Electronics tech, here. Don't let Grimes get away - that kind of diagnostic ability on the electronics side of things is only becoming more and more valuable on today's vehicles. That guy's worth his weight in gold.
I agree, Grimes has an excellent approach to fault finding.
I have spent almost 50 years doing the same, and for a young person to be this good
is very rare, i hope The Wizard pays him for his skills.
The stains were staring at him, i find most repair shops only fit new modules
and going to component level is just not done.
I would have taken the module home and recapped it, the Wizzard may be right that the
board only cost $10 to make, but at Bentley spares prices a new module could be $1000
or more.
@dcerisano
“That guys worth his weight in gold”
Lucky for wizard he hired a skinny dude.
I hope the Wizard rewards him for his fault finding skills.
These guys are born with it, i have been working in electronics for neary 50 years
and i am still learning.
Grimes has a great future as cars become crammed with electronics.@@jbro507
@dcerisanothat was leftover flux from separating the board from the housing. Caps were okay, but from what I can tell the driver for the lock motor failed. Replacement boards are affordable enough to pursue that route instead of holding warranties on an in house repair for an out of state car. We want to ensure this doesn’t ever happen in the future for the customer!
Because electronics on older classics are often overlooked, and rarely even considered when troubleshooting classic vehicles built during the 80s and 90s, I’ve started a business restoring the various modules and stereo equipment used in these vehicles. So far, I’ve had tremendous success repairing Miata stereos and some ECUs. The key is replacing the electrolytic capacitors - 90% of the time, the capacitors are the root cause of a variety of hard-to-pinpoint maladies.
My NB's 6-stack CD player only accepts one disc. I'd assumed it was a drive belt and haven't bothered to fix it. Perhaps one day... (And also upgrade to add the minidisc player if I ever come across one!) 😀
When I was working in car electronics we always specified the high-reliability electrolytics and doubled the capacitance the design called for; that's probably changed now.
Because electrolytic capacitors suck. And the cheap ones they use on cars wouldn’t have that kind of lifespan. It’s not just a problem for cars, old video games, and all other old electronics share problems with bad capacitors.
@@neilkurzman4907 indeed. I collect vintage computers and other electronics - it’s like a plague!
You must get this alot, but....I have a 1990 Lincoln Mark 7, the windows don't go down but the motors are buzzing. Any ideas?
@@steved3702😅 I'm 2:21 I'm on 2:30 I'm
It feels good knowing that my $70K Audi S5 is made with the same parts found on a $200k Bentley and a $30K VW. Reminds me of my Saab and its mish-mash of GM parts bin equipment.
That said, my Saab is currently sitting at 176K miles and aside from brakes, maintenance and the AC compressor, its been a damn reliable car. I bought it new, I was the only person who drove it, aside from a couple of techs, and I'm still on the original clutch.
The 2010 Lamborghini Murcielago has a cd changer in the glove box that also was standard in the trunk of a 99-05 volkwagen jetta.
Grimes did a great job explaining it all!
This engine is 2 VR6 put together, it's pretty amazing. VW also did a W16 variation for the Bugattis
If I could afford one, I still keep my Accord, as I would need a car for when the Bently is broke.
Keep it, you'll not buy a more reliable car.
Very wise, i live only 30 miles from the factory where they are built, and they are reknown for
poor reliabilty.
You don't want to own one without a good warranty.
And when your pockets are broke...
They should come with an accompanying Accord.
So, you'd be driving the Accord most of the time then... 😀
The car has 19,850 miles. Actually 0-60 4 seconds flat in the Speed (206 mph). I jacked up each rear wheel and put auto caster wheels (from Harbor Freight) on locked rear wheels. Dragged up on transport trailer with a Tahoe using recovery hook on front bumper.
The computer says "I'm shutting everything down so that you have to take me to the dealer for a thorough hosing"
Also a tiny tube of lubricant pops up out of the console. 😊
Amazing that an owner of such a luxurious piece of automotive engineering living in a sizable metropolitan area (I used to live in Chesterfield, MO, yuck) is willing to ship it to Kansas, well done Wizard as a credit to your reputation (and Grimes of course)
In Germany the auto club company ADAC actually have tow trucks that have a crane hoist on the back where they can literally lift a car, parked between 2 others. vertically and swing it onto the back of the tow truck. Likewise they can deliver it too. Ive never seen that here in north america. would have been good in this case
The Germans need it because their cars are so shit.
Yep with the CANBUS confirming the serial numbers of items like instrument clusters when one goes wrong it can lock the car up to the degree it locks the transmission - I think that may even be required by EU legislation.
In London back in 1973 our car was taken to the pound by just such a truck. Nothing special about that device. As Aussie tourists we managed to get the car back without paying the fees by being very nice to the guy behind the counter, haha.
You might see that on a 3axle tow truck for 18 wheel trucks. But towing fee would be $$$.
Why not just put dolly's under the wheels and winch it onto the trailer normally?
We've been repairing the Bentley Gen 1 & Gen 2 boot motors here in the UK for a few years. We replace the potentiometer if needed and upgrade the plastic gear for a metal one
I'm glad that somebody is finally making new gear sets for those trunk actuators. If we want to keep these older cars happy, more solutions like that will need to happen.
Or just manually close the boot. Why the lid of a car's boot should open electrically is beyond me. Are posh people so lazy that they can't be bothered opening and closing anything anymore?
ahh the ELV and KESSY. what a great system! At least your car will never be stolen (or used again by anyone)
The more I see all the problems with circuit boards and power-actuated whatnots, the more I want to restore an oval window Beetle. Gas, spark, air. That's it. Thanks, Mr. and Mrs. Wizard! 🤘❤️🙂🇨🇦
3D printing those new parts is an awesome way to keep cars on the road. Kudo's for that business to take on the process of scanning the old part and printing it new! I'm sure in the future we will see more exotic metal capable printers hit the market for less money too.
the thing to retain is that it costs half the cost of the new part ?!!!!!! damn 3d printing is expensive lol
I tried that with some plastic gears from a laserdisc player, they lasted a few discs then split apart.
The technolgy is getting better, but the plastic they use has no strength.
seems funny (ironic) that a $200,000 machine is undone by a $10 part (or two).
You'd think they would "test" them first...
@@BarbarapapeThey cheated you with crappy stuff. If they used something good that wouldn’t have been an issue.
@@oldrrocr that part does not cost $10 in Bently more like $1000++
Try buying a replacement tail lamp assembly. Sit down phone the paramedics to come and be present, advise them to have the defibrillator at the ready . When there and ready, phone the dealership .....charging clear ⚡⚡⚡⚡ 🤞🤞🤞
The IAC motor on a 2001 Mazda 121 1.3 L engine costs, get this, TWO THOUSAND DOLLARS in Australia. Same motor on a Holden Commodore same year costs $90 Aussie $$$. And yes those are dealer prices.
You and Mrs. Wizard are great! 🎉
Cars have gotten way too complicated. We never know when something will fail, with ANY car.
Cheap OEMs buy cheap parts.
My 98 LX470 is covered in electric crap and it doesn’t have these problems!
Then there is my 52 Plymouth and 1980 Plymouth. A small amount of electronics on the 80 but has never let me down
@@JollyGiant19 Toyota/Lexus usually stick with Japanese suppliers, and the Japanese really know how to make high quality electronic components. Having said that, even Lexus ICB's will have problems like leaking caps, dry joint and so on eventually - but yeah, they'll usually last twice as long or more than the German crap - also things like leaky caps and bad solder are usually easy fixes as long as the PCB isn't damaged - if you don't want to tackle it yourself any decent electronics repair shop can usually manage it - even if the PCB isn't great, that can often be dealt with by someone with a bit of skill too.
@@JollyGiant19it's a Toyota
desined to fail more like it...
As Craig from flying wheels has said, all the fun is in the cheapies. You get the driving fun ... and the thrill akin to skipping school as a kid due to the very low $ amount involved.
PREACH
My 1956 Holden car failed to proceed because the fuel pump diaphragm split. It was a $0.15 part. One $0.15 rubber can make the whole car totally inoperable!
And 1 split rubber can cause no end of problems .😋
@@anthonycarty9433 I hear you 😀
It continually amazes me the variety of cars you work on. Lambos, Ferrari, Bentley and Honda mini vans, no problem.
I was just talking with my friend Raif about this same thing..he said his Bentley has the same problemm...poor guy had to drive his Lotus today..
Absolutely GENIUS! I love the detail that the WIZARD goes into on his repairs. Keep up the good work Dave!
Love your channel, David Long the Car Wizard… So much to learn from it… 👍🏼👏🏼appreciated my friend!
Remember, Rodney Dangerfield said the perfect 2nd car is a TOW TRUCK.
Thank you Car Wizard for keeping my car repair education current. Bentleys are essentially German cars, and we all know the tendency to over complicate with substandard components and eventual high repair bills.
My Flying Spur has been in the shop for two months. I get back next week. The car didn’t believe I was stepping on the brake, so wouldn’t let the car start. The part is superseded but the car only reacts to the old part. And even then a section of the ignition circuit went out. Before that an egt sensor caused random limp mode incidents. Great car, but the tiniest things yield it stranded.
the phone in the armrest os not obsolete, its not actually a phone. its a privacy phone.
it only works when you have paired your own phone via Bluetooth to the car. To save you having to take your phone out of your pocket, if you want to take a call in private, through that handset, rather than over the sound system, you can 👌
Now that is a beautiful car, and in the beauty one can sense the power and speed that radiate from it.
Wes Anderson made a movie, Asteroid City, the main character's car breaks down and the mechanic says either the engine is destroyed OR you need a 50 cent part lol, hilarious scene in the film. It's strange what can bring a car down, but really it makes sense, too... a lot of "cheap" parts do important things!
OMG my cayenne turned into a POS because of that ELM module - top video guys !!
Thanks wizard for the knowledge
All that luxury and I'm still dumb, fat, and happy cruising in my 1961 Dodge Lancer with a Slant 6. It can do 0 to 60 in around 5 minutes and reach 140mph off a cliff. It can go even faster if I shove my feet through the holes in the floor boards to give it an extra push.
If you replace the 170 with a 225 ci engine - you will reduce your 0 to 60 time by at least half a minute - and a little faster off a cliff as the 225 is slightly heavier.
@@georgebettiol8338
You're right. 😆
This happened on my B6 Passat, as you say a common issue.
A good way of getting power to the car is bridging PIN 16 and PIN 1 on the OBD port. That will give enough to get the parking brake released and may also allow you to get the car in neutral.
Mine is a manual 6 speed so the neutral release wasn't needed.
Be aware that sometimes the module going also causes an EEPROM corruption in the immobiliser and may cause weird errors in the future until it is replaced as well.
Very awesome guy you have in omega clinic now,
Very much respect !!
I'm a 57 year old master mechanic/gearhead from Germany.
Audi calls it an Access Start control module. I had to get the one in my Q7 rebuilt by Speedometer Solutions recently.
The issue is that nobody really pays the level of attention to the electronics in the same way that they do the mechanical parts.
I would imagine the circuit design is just fine - the problem is they would have used poorly manufactured components, like capacitors and resistors, poor quality solder and so on - many electronic components will fail eventually - but if you get a top of the line Japanese capacitor for example, it'll last many decades - if you buy some cheap no-brand Chinese one, you'll be lucky if it lasts half that time before it fails completely, and probably won't be operating to spec for a lot of time before that. German manufacturers in particular seem to love to use the cheapest ICB components they can lay their hands on. Bean counter engineering.
Now of course, we are seeing the same issues with mechanical parts too, at least in the spares market - it's flooded with Chinese knock off junk that just isn't reliable at all.
@@Beer_Dad1975 Nope the main problem is lead free solder. the solder doesn't spread as well as leaded solder does on the pads. Unleaded solder also grows 'tin whiskers' over time and any boards in important areas should be conformal coated as a preventative. Capacitors are subject to breaking through vibrations but this is not as common as tin whiskers. One of our customers uses flexible termination capacitors in important locations on his pcbs and his faults have reduced markedly.
@OP You do not understand what you are talking about. Automotive electronics get a very serious level of attention. Beside pb-free solder, it is common to have conformal coating and potting failures, which are added to protect the modules from weather. Capacitors tend to have low failure rates as they are now solid state tantalum electrolytics for higher values.
Unfortunately that is the role of an immobilizer circuit, to prevent the car from starting. In event of a failure, it will no longer provide the logic function to allow ignition. The set conditions for which the immobilizer may not allow ignition, or in some cases, not even access to the car, is complicated, and occasionally may be triggered by a sensor, fuse, or ground fault (e.g. rodents or old age chewing through wiring harnesses)
The boot issue with the soft material gears is an annoyance, but won't prevent you from using the vehicle.
SAC95 solder is adequately resistant to tin whisker formation due to alpha-tin state conversion. If it's a particularly crucial safety related circuit (e.g. accelerator pedal sense plate) you could go with indium based solder.
Sadly the mechanical parts are not that great either
Total rubbish. My 1998 Isuzu Monterey (Trooper in other markets) got stuck in Nolan's Brook and the 4WD computer under the driver's seat took a bath. Only had 2WD until we camped overnight and I pulled the computer out, opened it up, and dried the circuit board and the connectors. Put it back in the car and it was perfect for the next 10 years till I sold the car.
Wow, what a beautiful car!
Bentleys are absolutely beautiful. And I wouldn’t take one for free.
Tyler is a good addition to the both the shop AND the youtube channel
Met him. He's a good dude!
The more i know about these modern computer vehicles The more i LOVE my early 2000 GM & FORD Trucks
Grimes needs a wizard uniform😊Great content! Thank you for sharing your honest knowledge to keep us informed when we go to our local shops.
Too hot for a robe right now. 😂
My Corvette has a similar steering column lock problem. Fortunately I installed a bypass harness several years ago to preemp the problem.
Very honest of Wizard finding the $10 part problem. Any other foreign shop would say $1000.
just a thousand?🤣🤣🤣🤣
Oh he didn't say the part was $10... He said the board cost $10 to make.
Please don't confuse! Wizard said the PCB board (mass produced) probly costs $10. That is not the complete replacement part, nor its retail price. Also no costs for labour (troubleshooting, sourcing, ordering, reassembly) included. Even a remade PCB-board or the service of replacement of single components is likely much higher than $10. A OEM replacement part might be even cheaper, if its not labeled Bentley but identical part also used in a "generic" Audi/VW. Even then it still needs programming to the car… Hell of a hassle.
Wow! It's beautiful!
As always, great video. If I could afford the GT Speed, I would buy it.
Steering wheel lock malfunction a very common issue in Corvette C5s. The drive pin locks place. Had 4 C5s and after he first one malfunctioned-One of the first things I did when I bought subsequent C5s was buy a Bypass for the lock mechanism. A $120. investment that ALWAYS eliminated the this common issue. Leave it to the Germans to over-complicate this issue.Their mantra is -"why use only one screw-when two will work better"
Wonderful always to watch your vids........ there's so much that goes into a Car 😅😊😊
What a Beautiful looking car.🇬🇧👏
My favorite car of all time. Fast smooth and quiet. The Wizard 🧙♂️ is a lucky man to get to work on these.👍☺️
Sad to see the owner neglect to clear the leaf litter from the base of the windshield. Beautiful automobile and great video Car Wizard!
Gorgeous vehicle
Wonderful car.
It's basically 2 VR6 engine combined
That interior just confirms my dislike of "Piano Black" trim - it just looks so dirty so soon and is easy to scratch.
@13:30 Derek from @vicegripgarage would be proud of that superstart battery 🤣🤣🤣 does it have a go handle 😁😁
That's a nice piece.
I had a Mercedes E class 2006 and had the same problem as the Bentley. The car was only 4 years old. BUT even Mercedes couldn't diagnose the problem. The car was down for 3 weeks till I spoke to a Mercedes Car Breakers
Just as people have doctor's visit anxiety this Bentley was having Car Wizard anxiety
Beautiful car
Grimes is a keeper.
Timeless styling
These things rip the streets here in Kuwait. There's one sitting in the garage in my apartment that just sits collecting dust. Sits so long the suspension is always collapse
$10,000 USD just to repair the front suspension... I speak from experience.
Wizard MUST take care of Grimes. Dont force him to open his own shop.
.... Looks like it had an Over voltage fault on the control board, or your boy burnt some flux when he was trying to see if he could replace some components to salvage the part. It's all generic parts except for the control chip so if it just a failed capacitor, resistor, or relay it's $100- $125 fix with labor included. Always worth seeing if you can save the electronics when possible.
Like the red accents. They really lift the grey.
97-04 corvettes had a column lock issue. Corvettes of Houston made a ton fixing it.
That’s a nice VW !
Cannonball run in style! 😊
Come here to Palm Beach. These are everywhere. You can find older models with 45k miles for unbelievably cheap.
Magic Mike never really left. Wizard sends him ahead to cause issues with the cars before they get delivered :P
Someone i knew owned a mercedes, but i forgot which mercedes. It had similar problem and he bought the module for 100$ ish from marketplace. Also we are not from US. Helpful video 👍
It’s common to bypass the ESL on the Benz with an emulator. That’s likely the course of action they took. Programmed ESL from MB is roughly $4k installed and they’re currently on back order.
Did they mention the cost of the replacement parts? I heard that it "probably costs $10 to make", but not the retail cost.
Such a pretty vw
It's good to see aftermarket companies filling niche areas like the gears for the trunk opening mechanism. Being able to get replacement gears for my W126 odometer was great. It definitely makes me appreciate owning a car that doesn't even have a computer in it with my 1984 Mercedes 300SD. It seems so unnecessary to have this level of computer control over the car imo.
When I was a kid, a cousin had a Dinky Rolls Royce toy. He smashed it up and said, 'Now it's a Bentley!"
I think that word has got round between the cars and they know your reputation now Wizard. 🤔 😉
Grimes is the man and very smart guy.....Thanks to y'all
Great video. I bet the $10 board was more than that to replace.
Wow Grimes is quite the pickup for the Wizard's shop
It was a precision strike. 😂
Wonderful video... can you go to Flying Spares or IntroCar for the part or is it a VW / Audi part so you can source in USA?
This is a common issue and a SECRET. When people can't start their cars because it has no power are they going to think I need a new steering column?
1:20 bird cutters. Slices and dices the ronco grill, but wait there's more.
This is what happens when too much technology is crammed in a car. Poor quality and/or unproven tech results in frequent problems. Manufacturers gouge customers.
The less computers on a car, the better!
Use Japanese firms to make your electronics and guess what, you won’t have issues. New Lexus’s have a ton of technology, and when was the last time you ever heard of an electronic issue with one of them?
Marty McFly: All the best stuff is made in Japan.
Doc Brown: Unbelievable…
@@hokie9910 Japense OEMs also use electronic components made in China, however they 'ensure' the parts are manufactured to a set quality standard. Chinese parts manufacturers are capable of making both good and poor quality components - as it depends on what one is prepared to pay and the 'imposition' by the OEM of strict quality assurance/quality control measures. The evidence accumulated over the last decade or so tends to (sadly) indicate that German OEMs are overlly controlled by 'bean counters' who tend to opt for the lowest price whilst paying scant attention to quality assurance/quality control measures.
Sooner or later technology is bound to fail which can cost $$ to fix
Are those nylon gears? Wonder if it's viable to replace them with metal (e.g. brass) gears. That's what they needed to fix a parituclar model of power window notorious for failing.
I no industand...pls explain simply 🎉🎉🎉
this car will be great just dont stop before its finished.
To help car owners and shop owners with electronics issues is exactly why I founded Motivelectronics 18 months ago.
You ought to make a video here to advertise your services.
Nice
thats interesting. my 04 rav4 has the same security lock thing (without the parking brake). if it feels the steering wheel move while off it locks and doesnt let u start the car. luckily for me all i have to do is hover the steering wheel between the the 2 lock points (there's a bit of play when its locked) and the key turns.
You have to see these on the Autobahn,at top speed….Breathtaking
I think $10 is a big over statement. I bet that board closet $1 to make. But that doesn’t include the r&d to design it but pcb’s are cheap to make over seas
Cool elect /pc diag
Hey Wizard! Another great video you’ve made. Just a question: it looks like you have a huge shop, so how many employees do you hire? We never see mechanics working in your videos.
I’ve stopped by Omega on a trip, and it’s a lot smaller irl (in real life). The videos are photographed with a wide angle setting so objects seem larger.
Shop manager, shop owner, and two full time mechanics
He said in a previous video that he films during lunch breaks and after work hours
Red Barchetta was a documentary 😂
Darn Circus Boards!
Yeah, and no tigers or elephants! 🐘🐅
Ah so that was the problem with John Ross's Bentley Continental someone had tried to fathom the problem and dismantled the centre console.
Unfortunately the shift interlock had a piece of plastic lodged in it and I had to remove the console to access it and clear the blockage. Otherwise it would’ve remained untouched.
@@GrimesGarage To electrical test engineers. Investing in a Fluke IR camera would save so much hassle. At the design stage you can see what is getting hot.
man your beard is magnificent
General Module in any BMW 850 has the capacitors fail after 25 plus years which takes out a bunch of interior electronics. $6 in parts or send it to the correct guy for $60 to have then new ones soldered in.
You need two Bentleys because one will always be in for repairs 😅
Sweet
