Lightbulb problem? That's an engine-out service.
Just do an LS swap. That will solve the bulb problem for sure.
Nothing would surprise me anymore, what with the way cars are engineered today. Just changing a headlight has become a big deal.
Which requires the whole front end of the car be removed. Everything back to the firewall. ;-)
@@Flies2FLL just junk it, take it to the scrap yard 😅
@@chrisfurlough466once you do an LS swap, you’ll probably never need to pop your hood very often afterwards.
Having a honest mechanic is priceless
I had a lightbulb warning for my license plate light intermittently going on and off on my old 2013 VW Eos after the dealer replaced the dead bulb. After a few weeks I bought two new bulbs even though both were lit (there were two bulbs for rear license plate on that car) and I found the dealer replaced the bad bulb with a different size bulb then the one that was there! With the matching bulbs installed the warning went away! Wish the VW dealer knew how fix a VW!
I've found over the years that most mechanical devices that are made in the UK need a knowledge close to a PhD in mechanical engineering, while a lot of mechanical things built in the United States have a comic book type of manual that can easy be read. I was in the Canadian military back in the 70s and when we switched from British equipment to American equipment like switching personal weapons from the FNC1 rifle to the C4 version of the M16 rifle, the FNC1 manual was the size of a Sears catalogue, and the M16 manual was a comic book. You have to know where to look and how to read to find what you need.
The Brits also speak in convoluted sentences, and for that reason I dropped any class in university that had an instructor from the U.K.
It's a VW 🇩🇪
@@bactaniteits called English speaking and your remark is - frankly - absurd.
@@naradaian You must be English. I'm an American who went to university in Ohio. The Brits just take 10X as long to explain things. Btw, my mother was from the U.K.
Also helpful is a hogwarts trained wand carrying technician
Always ask yourself first, "What Changed?" New batteries were installed. Is it possible a ground return line was loosened during that process? A loose ground could be the root cause.
Hey Wizard. VWAG products of this era had tons of issues with factory grounding points not being sufficent enough to provide an effective neutral circuit, then proceeds to backfeed ground through the connector. I bet that connector for the suspect light is burned on the ground pin. Best fix is to add a ground wherever is easily accessible. Had this issue with my 07 audi tail lights. Factory ground was not sufficent had to drill and add one
Yep I'm having issues with the light bulb fuses and similar codes even in my 2012 Skoda. It's irritating to see the light lit up for basically nothing lol.
It wasn’t not sufficient. It was done poorly on purpose. The VAG management was focused on making their customers get to the VAG dealerships’ shops time by time to keep their workers busy and bank full.
It sounds like a poor connection with wiring, big pain to trace wiring.
Did this on my BMW also a 2016 model. Drilled a hole in my trunk behind tail light and. Grounded it properly now fixed but felt horrible taking a drill bit to my pretty Bimmer!
That was my thought exactly = check the earths.
I repaired electronics for 20+ years and even we had times he had to do the same.
The gauge cluster surround reminds me what was in my sister's old mid-70s Firebird 😅
As i have said before these cars are made only 30 miles away from me.
And my friend who works there will tell you, eletrical gremlins are very common.
and not easy to find even on brand new samples.
At least the Wizzard has the sense to not replace a lot of expensive parts until the
fault is permanent.
Good luck with finding this fault.
And the whole electrical system is Bosch.
@@michaeltutty1540 And reknown for expensive issues that are hard to rectify.
An extended warranty on these cars is very expensive but a must or your bank
account will suffer.
One word…. Integrity. Thanks for the video.
This owner is awesome, he put a 1980 Pontiac Firebird dashboard into his Bentley - crazy
I recently went to a Toyota Dealership just for an oil change, and the mechanic came out and told me that I needed a new rack and pinion which would've been almost a $3k job. I left and got an opinion from another dealer an hour away and the mechanic saw that my rack and pinion were perfect and no bushings were damaged. He even showed me, unlike the other mechanic. I ended up just rotating the tires and balancing them with alignment because the other shop screwed the orientation of my tires as well. I ended up with a $360 bill instead of the $3k. I have grown tired of going to different dealers for opinions and everyone has a different opinion.
I'm sure you've heard the old saying, opinions are like aholes, everyone has one. 😂😅😂
My Mercedes 550 would start vibrating and shuttering after 90 mph. Took it to the Benz dealership and told me my AWD transfer case was bad and quoted me 9000$. 😅. Went to a private mechanic and he pulled off the wheel and showed me a badly dented rim. I bought a used rim for 250$ and it runs like a top. That was 8000 miles ago.
@@Wargasm54I had a 116 Benz that had a ticking noise when I was moving but not when stationary. The local Benz mechanics scratched their heads over it and I told them to not worry we will fix whatever is making the noise when it breaks. My brother discovered the reason - it was a loose wheel weight dropping and hitting the metal hub cap! When i told the guy at the garage they just shook their heads in amazement.
@@ianmontgomery7534at least you found the issue before paying through a troubleshoot with multiple mechanics
Just finished a two year long debacle with my C5 Corvette's column lock giving the famous 'pull key, wait 10 secs'. $3,000 and a bunch of replaced parts later I finally decided to tear into it myself inspect the circuit myself. I am by no means a mechanic but I was able to find that my BCM had corrosion on the internal circuit board. ~$600 and a 30 minute installation, including someone with a tech II, and it was good as new. I was a victim of the parts cannon :(
Here we see the Phaeton convertible, ...in its natural habitat...
Hilarious 🤣.
Drophead coupe...
Too many mechanics treat each hour changed as a way of making money. The Wizard thinks of helping customers as his way of earning a living.
My wife had an E46 BMW. She kept getting a dashboard warning saying a RR bulb was out. It wasn't. I cleaned all connections, switched bulbs side to side,checked continuity and resistance on both power and ground, even bought a new bulb from the dealer, the problem kept randomly coming back. I finally just ran a jumper wire from the battery direct to the fixture. The problem went away and never came back. The only answer it could be was a factory ground good enough to keep the light on, but intermittently bad enough to trip the sensor. Sensors seem to be TOO sensitive on a lot of German cars
😮Mercedes require German bulbs that have the oval lead bulb contacts instead of round dots otherwise the light bulb fail light stays illuminated! I have the e46 e36 and e90 but haven't had issues with AutoZone generic bulbs but did so with the r107, the w124....and w123 Benz cars.
My old Jaguar XJS for years it kept telling me a sidelight bulb was out and I knew there was no side light issue. I just put it down to Jaguar electric gremlins and never let it worry me.
Lucas-The Prince of Darkness!
@Big_Ben_from_La_Mesa eh m8, Lucas made one thing that didn't suck, unfortunately it was a vacuum.
To me, it sounds like a bad connection somewhere in the CAN bus. Using a scope could uncover a problem. The guy running the South Main Auto youtube channel does a lot of work like this.
For some reason when you were reading the manual about the air bag light I was reminded of the years where GM products had a snowflake with a slash showing the A/C is off instead of a snowflake to indicate its on.
Always great, informative info. By the way, Mrs. Wizard does great videography for you.
9:51 - RTFD...read the fucking directions. Absolutely.
I know it as RTFM but it has the same meaning.
Intermittent problems are the worst. I deal with it daily on industrial machinery. Just break so I can find the problem, or just work. So frustrating. Dead motor, dead servo, dead relay, dead battery, dead solenoid, broken limit switch, bad proximity sensor. Give me those all day long.
"we don't do the parts cannon on Bentleys"....
I just imagined an estimate that involves engine replacement to change the light bulb. And when owner raised brows at the bill, tell him, "That's normal. A Bentley thing. Comes with the privilege of owning one"
My nephew in Australia had an Arnarge and was told to replace the LEDs in the dash would cost $15K. Fortunately they didn;t need it. I find it hard to believe that there would be a problem with the LEDs unless they were overloaded.
I’m learning so much from you.
Just replace the bulb and see what happens. The actual LED diode may fail intermittently regardless of manufacturer or application. Put another working bulb and it may not fail again anymore.
I think someone put in the wrong bulb in. The resistance is different with the bulbs that Bentley uses! Sure it will work just fine but the computer sees the resistance difference and thinks there is a problem and lets you know! So I'd replace the easy turn signal, running lights and such!
That would trigger the code immediately, not once every 3 weeks.
Why do people want automatic trunk openers?! Just one more thing to break.
just be sure to get the kind that doesn't cut off your fingertips...
oh, they ALL do?🤣
Because work is for commoners. Pull yourself together man 😂
For most vehicles, reduced effort, easy to close with your hands full of stuff. For Bentley, so you don't put handprints on the trunk lid.
I'd never own a car where the hubcap initials are up side down when it comes to a stop.
The more complicated electronics gets in modern cars, the harder it is to track down electrical gremlins. My lowly 2018 VW Sportwagen 4Mo developed a strange electrical problem with the auto-off interior lights. They would stay on all the time even with doors closed and key off, also while driving. The dealer did a total parts cannon (under warranty)replacing door micro switches, overhead console switch modules and even the body control module. Finally had to hand off to a visiting VW engineer who finally solved the issue. Something with the CAN bus. They wouldn't explain. Took two months and they had to spring for a rental car.
I swear the Euro style manufacturers need to have Toyota or Honda do the R&D on especially electrical systems.
I came home from work, Parkes my R53 MINI, and the RR tail light stayed on. I tried cycling the ignition, cycling the lights. Etc, and the light stayed on. Said screw it, and went to bed. Got up for work, light was still on. Drove to work, and light went out when I shut it off and has never done that again. I'm at a loss as to whether blame this on German engineering, or Bri'ish construction...
Wizard, in Vag cars normally that relates to the airbag cable that is under each seat. They get wet/moist, and then become corroded. Remove the batteries, lift both seats, unplug the airbag cables, give the connectors a good clean, and it should go away.
I admire your work and see you as a role model! Since October last year I am a shop owner as well (in Switzerland) and I always tell my people: you may have a quick win, but being honest you go a lot further! We let the customer know, if a small issue can cost a fortune to solve! We actually advise them, to leave it alone. It’s his call! Cheers and keep up the good work! 👍
Thanks Wizard!
At this point these videos are just testament to why you should bring your car to Omega. ❤❤❤
Its in another country
Great video today, thanks for the sound advice.
Check if all bulbs are correct wattage, or even LEDs?
Exactly 👍🏻. LED’s will show a bulb out on cars that weren’t designed with LEDs
Working on high end cars you should know,my car will say a bulb is out ,yet it works. 2-3 weeks later it's out.As bulbs come to end of life resistance goes up and triggers warning ,and works until it blows
Or replacing incandescent/ halogens with LEDs can trigger erroneous caution lights too.
Some black tape over the light fixed can’t see it
Surely piano black tape though!
Loose wire on the bottom of the passenger seat?
great video! Good to see honest people still exist!
When Wizard showed these plastic gears I lost all my remaining respect for Bentley.
They are VW parts really, probably shared with a Golf
@@texarkana3781No it's BY specific for sure and really expensive. Don't ask how I know. Sucks to have these plastic gears put in in such an expensive car to save 30 cents and a tiny bit of weight. WTF where the engineers thinking
Well, in this case plastic gears are a good choice. They are intentionally designed to fail if someone accidentally slams the trunk as opposed to using the power button. If the gears were made of metal, they could damage a lot more including the struts and support structures. Then you’d of wished you had plastic gears. Use your head.
@@Wargasm54 wrong dude. there would be a failsafe mechanism to prevent that. no need to break the gears. they are not even supposed to be changeable or serviceable. So every time someone closes the trunk the "wrong way" you are supposed to change a 1500$ part? I don't think so. NO my friend, this is cheap out plastic crap for no reason. Actually I do drive a Phaeton and you actually can manually operate the trunk, that doesn't break anything. You even have to if there is like a battery failure. there is even a failsafe way to open the trunk if the electric system fails.
@@Wargasm54 I too, am not convinced that those Plastic Gears are the best solution, and here's why: Those Plastic Gears have to work AGAINST the force which is provided by the Gas Struts - in holding-up the Trunk Lid. To close the Trunk Lid (working against the force of Gas Struts) is quite some force for those Plastic gears to handle, day in, day out. That force to raise the Trunk Lid is increased momentarily - if the Trunk Lid is covered with snow. Most plastics degrade with time, become brittle at low temperatures, and this is well-known. The complexities which have been designed in many modern cars, both electronics and mechanicals - leave a lot to be desired. Give me simpler cars from the seventies or eighties every time, because we are seeing a bottomless pit of money being wasted in moving you from A to B.
It's an Audi A7 with a different body and interior at twice the price. It's all marketing. The Wizard has also mentioned in the past that taking the car apart may make things worse because there is the chance of breaking something or forgetting to fully reconnect something causing a new light to come on. As he said, without more data to go on, it's better to leave it alone.
I’m glad to hear your health is doing well. I can tell you haven’t gone to the Doctor lately. I just want to inform you, the doctor will run up the bill and order all types of tests.
I have had a bulb issue where theres a bulb out light on but all bulbs are fine, the problem is where the module monitoring the bulbs works on voltage/current flowing through the circuit and if the bulb is old, it will use either more or less volts/amps and this triggers the fault but the circuit is good so the bulb still works. When visually checking the filament you can see its just about hanging on to work and a tap on it would probably break the filament. A new bulb will use the correct resistance to turn off the bulb failure light. The problem on mine was an E46 bmw coupe with the single filament bulb working the tail/stoplight and using different volts or amps to work instead of a twin filament bulb with separate circuits.
The best car repair channel on RUclips ❤
The B in Bentley is for BAMBOOZLED.
Mr Wizard, I really enjoy your channel and how you share your knowledge and experience. I’m not an auto mechanic at your level by any means. I spent many years “flipping” cars in an honest and legal way during the 17 years that my father had a shop. Dad’s shop was never near the level that you operate. In early February of this year I emailed you asking your opinion of Hyundai/ Genesis vehicles. At that time you responded that you had a video coming out about these vehicles and that you don’t recommend them. I follow your channel faithfully and will continue to do so. I’ve yet to see the video your email said was coming out. I personally have had several Hyundai vehicles. I have family members that have had this brand. I have done the maintenance on all but my niece’s newest one. Yes, these are cheap cars. It’s been my experience that they are easily repaired and cheap to maintain.
Probably a resistance issue with one of the bulbs.
More shops should be honest like yours!
About three years ago I installed clear front side marker lights on my '14 Cayman S. I added LED bulbs as well.
Last month all of a sudden, I kept getting a side marker bulb out warning. Swapping the bulbs caused both sides to indicate a problem, when the bulbs were operating just fine. One finally burned out, so I replaced them both with new LED's. Still got the bulb warning. I cleaned the plugs with Stabilant 22 to no avail; I reinstalled the original incandescents and put the LED's away, problem solved. Why the car was happy with those LED's for three years and then suddenly got pissed off I have no idea; This is literally the only problem I have had with this car, which has a little over 70K on the odometer.
Go figure~
😡
Now I know what to look for when I find a 2014 Cayman S to buy lol
It's just a fancy Volkswagen. Which means all the reliability problems Volkswagen has are multiplied by at least 10.
Love that Bong is the exact same as a 2010 Golf
I got lucky with out local Honda dealer. Several times they've proven honesty. We ran over a dead deer once and it tore some cover thing off on the undercarriage. They did a quote and when we went to get the work done it ended up not needing a $100'ish part and they came out and told us that and the bill was cheaper than we thought. That kind of thing really sticks with you in a positive way. Makes it incredibly difficult thinking about getting a different brand car or from somewhere else.
And I've tried independent mechanics. Wasn't impressed. We have mandatory state inspections here and some shops will do what I call the old/used/high mileage car tax where a sub $50 inspection is always $300 a year. Usually for bullshit, a new set of wipers this year, new bulbs every year, some headlamp cleaner because allegedly the lights aren't bright enough, and my personal favorite new brake pads every year even if driven less than 2,000 miles for the year. That's when it hit home time to change shops.
One of the best things you can do to keep these cars happy is to keep it on a battery tender when you are not driving it. The batteries in these are expensive and they do not like a discharge at all.
The first thing i do when a get a new(to me) car is to read the manual from the first to the last page at least a couple of times. It saved my butt al few times.
Just fitted a main battery to a family owned continental on Monday, often the wrong battery type and size is fitted. You need VCDS on laptop or a good ODB reader as often they just put the lights on for fun. We also found a tracker connected in the boot which has now been disconnected.
My Audi a4 airbag light was the connection under the drivers seat replace fixed
Problem does sound like the micro switch underneath the brake pedal. If one of those 2 switches have a connection over 1/2 an ohm, it will trigger a check lights warning message. As far as the abs light it sounds like an intermittent dry connection on the ignition switch and or the air bag on off switch.
A lot of foreign cars have to get a new battery coded to the vehicle as well SMH
spray deoxit on the bulb sockets.
Has a little pine tree. New car smell
If the bulbwarning light comes up on Hoovies Volvo 760, then these are made with a large relay that uses spools that see the balance, left vs right side lights. Having another wattage on one side will illuminate it. Leaving it lit for a long time will burn the relay out and the warning light would stay on for ever. Better change both side bulbs every time one blows, this keeps it in balance.
Hey now you don't want the Passat turn stocks in your $200k land yacht? Such a shame they took what Rolls gave them and decided to try to cut corners anyway they could.
All cannon fire is indirect - the parts cannon is no different. Rarely does it hit the target on multiple volleys.
Glad the see the Wizard army experience taught him that life lesson so he can pass it down to his customers. Good job!
Did they program the battery to the car? Its oem or aftermarket? What kinda quimestry are it regular or agm? Does bentley require batteries program like audi?
I had the same wuestion during this video. My 10 yo vw need programing as well
I watched your video about "How RUclips wrecked my shop". I must say this is quite a prolific channel. Most other channels are weeklies, not dailies. Great content, you could just put out one big one every week or so and no one would fault you for it. Might even allow you to put some real Wizard SFX in there.
At VW I had tons of those passenger air bag codes because people will put their bags of weight on the seat whd it will not be enough for light to turn off so it will tunk there's a fault. We told customers if youre putting weight on seat buckle it up so the sensor bypasses the check of seat weight and just arms the airbag. That's probably what this is
I saw the same problem when I worked as a Master tech at Mazda. The Gen 1 Mazda 3 has the exact same fault even when that airbag bulb functions. Turns out that someone put a normal T10 bulb there, where there needs to be a specific T10 with a specified resistance to it. You had to order it from Mazda ($5 or so).
Give it a try... Not much to lose.
Even though a bulb works the electronics might think it's open circuit due to a contact not pressing fully. The bulb test injects a tiny current through the filament and if it's outside a set limit then it's deemed a failure. The bulb might light fine in normal operation. Reseating or light sanding the contacts is usually the solution.
Wizard, please open a shop in Palm Springs. Thank you.
take a shot everytime he nods
Some BMWs are sensitive to the bulb used. They need a silver tipped bulb not a brass colored bulb tip. The resistance of the metal will give the wrong answer to the car and it assumes the bulb is out when it’s not.
Thank you for your integrity, how do I find a mechanic that is honest.?
On day, on the 10th of never, you’ll find one!
Intermittent problems can be some of the hardest problems to troubleshoot. Since todays's cars have so much electronics, intermittent problems occur more often.
The first thing to do is to look at previous repairs. Bosch went and multiplexed the electrical system. Everything works via feedback. Use a part that feedsback the incorrect frequency and other things will go bad. The German wiring is the biggest issue.
can you do more videos on normal / regular cars? I would like to see what to buy/ not to buy for Acura, Lexus, and other Japanese cars.
Newer high energy cars need lithium batteries vs old school lead acid. Lithium LFP(lithium IRON) hold power consistently at higher level, higher ccs, no corrosion or explosive hydrogen gas, last 3-5 times longer, longer warranty, much lighter, charge in minutes vs several hours, hold full power down below 10% of charge(lead acid has trouble charge dropping 70%) no need for trickle charger if storing car over the winter months
something similar happened to me, my e300 have shifting issues and the shop told me a I need a new transmission, but it turns out to be a $75 engine sensor.
my michanic think same way you do work 👍🏻👍🏻👍🏻👍🏻
Did you do a full code scan (all modules)? It could provide some direction.
The owner should take it to a Bentley dealership and have them do a full factory reset with the manufacturer diagnostic tools. Should have been done when the batts were changed. Poor thing is in a weird state.
this car is a dream car
You should do a video on reliable and unreliable exotic used cars: Rolls Royce, Bentley, Lamborghini, Maybach, Ferrari etc
My jetta 2013 does the same light bulb thing, tells me of a burnt bulb which is not.
Why can't every automotive technician be this honest and competent. Wizard, I wish you were geographically close to my location so that I could have you check out things for me.
i have touareg that year, they share same parts. i had same thing when i put led light insted original normal light.. after 5 days i replaced with normal and problem solved.
It did.
the design of these continentals is timeless...
As my Mercedes got some age on it, the burned out bulb indicator would come on. When replacing a working bulb, I noticed the inside of the bulb would be coated. The resistence would change making it appear the bulb was burned out.
Intermittent electrical issues are always the worst to diagnose.
IMHO with those two battery covers off I would have checked the voltage drop on the positive side and the return side. I have seen a lot of electrical problems being fixed by just breaking loose a bolt/nut and tightening it back up.
You need to check that the bulds are the correct type and correct wattage. The difference in wattage can cause issues.
You have it absolutely right. Do not fix this crap. That is unfixable Lefty
Also, a lot of replacement LED bulbs will send false “lightbulb out” signals to your cluster. I guess because they don’t draw the same voltage/wattage and the computer thinks it’s burnt out. I’ve replaced bulbs with LED bulbs in my Mercedes and the cluster will still tell me that particular bulb is out when in fact I walk out to look and it’s working.
Hard reset? Worked like a charm on my Buick for those wacky intermittent electrical issues pituitary after a weak battery change out
Particularly
My son's volvo from 2005 was like that & we changed out the battery & now all the modules that had 1 code now have no codes.
Be safe
A CHP friend of mine said that when a warning light came on with no fix, they just cover up the light with black electrical tape. Solved.
I had a similar problem with the ABS light on a Dodge P/U several years ago. Somebody had replaced the original stop light bulb with the wrong bulb. The bulb fit the socket correctly but was the wrong amps.
Your right, the M.B. dealer replace over 8,000 thousand equipment on my 2015 E250 Diesel, and the car did not start after the repairs, so I sold the POS and got a Toyota, never again buying a German car.
Mrs Wizard’s like: “But Wizard, we got boat payments to make! Let’s get that parts cannon loaded!”
VW architecture.. a non standard bulb has been fitted. Plus ecu needs update when new batteries installed
Grounds / harnesses rubbing.
It's crazy how that stuff works . Was the Bentley in a flood by chance?
