Mk4 VW 1.8t problems
HTML-код
- Опубликовано: 20 сен 2015
- Another issue that can arise is the use of the wrong kind of oil. These engines require the correct synthetic oil.
And of course the correct timing belt intervals.

221,000 miles and still going strong. Got this car when I was 17, so as you can imagine it took a hell of a beating before I started caring about it. Original clutch too!
How’s the car driving now and how many miles?
265k miles here
the 1.8 Trubo is a great engine... fluids and timming belts need to be on top... and since its turbo needs warm up when cold...and not weather keep cool otherwise a great efficient engine with great MPG'S.. my second. 1.8 t no problem..and miles at 190k
Can someone help me identify the hose he's talking about @2:45 please
1.8 t is GREAT PIECE OF SHIT .a lot problems with that disaster engine .With vacum ,with belt ,with lifters ,with chain tensioner ,with oil sludge .
Everybody who owned that shit goes into mechanics nightmare .😏😏😏
That is a true !
You got some good points here but I think these are very reliable engines with normal maintenance, I've seen these with over 500 000 kilometers. My ex A4 with 1.8 non turbo (same engine almost) had 350 thousand and still going well
Literally one of the best 4 cylinder engines ever made. The EMISSIONS systems are over complicated I agree. Once they no longer have to be emissions tested delete the SAI, EGR, and the other emissions systems and you’ll have a simple, powerful turbo 4 cylinder that gets 30mpg and is very easy to make 300+hp out of. The engine itself is very strong, built with forged internals from the factory that can hold up to 500hp, many RUclipsrs and forum members confirmed.
Things tend to wrong with these engines simply because they are old now. Wear and tear thing. Nothing internal will go wrong.... as long as the oil, coolant and timing gear is good then your good.
its a very accurate and fair summary since i pretty much had all the problems you covered. thanks a lot for putting the information together.
Most reliable engines in the world
People just don’t maintain or do any preventative maintenance
Completly agree! Bought a Audi TT 1.8t and had loads of codes due to leaks and what not, couple of weekends with research everything was back to normal and 100% now that she’s being looked after by me
9 times out of 10 when something is broken on a 1.8T its always rubber/plastic/vacuum related. There are plenty of delete kits out there and replacement hoses, spending a weekend or two replacing all the hoses massively improves their reliability and makes them basically bulletproof, planning to do mine to ease my mind. The only other issue is that people dont change the oil frequently enough and they run super hot so they sludge up and have an oil pump failure or run like shit until they wear out. 10k intervals are the perfect way to kill these. 5k minimum but 4k is better. Mine is only at 120k and i had my fair share of problems thanks to previous owner but its been trouble free since i sorted them. They are a good engine if you know what you sre doing and you take care of it. They are very rewarding to drive. Not to mention they are a pretty flexible platform. Variety of vag/audi stuff can be fit to these or made to fit from different coils and turbos all the way to DSG's from newer cars. There is a reason why people love these. Had my fair share of ups and downs with it and even with all of its issues you cant really find another car with an engine for this money that runs as smooth and powerful as these. Not to mention okay fuel economy.
Can someone help me identify the hose he's talking about @2:45 please
So to make things simple : remove the egr,remove cat and remove the rest of emmison control if any,and enjoy.

268k on my AEB 1.8l turbo ‘99 Passat wagon. New water pump, alternator, fuel pump, timing belt and coolant flange but still going strong. Always use full synthetic oil and getting 30 mpg average. I paid $1200 for this previous 1-owner vehicle with 160k miles over 6 yrs ago now. Love my Passat!
Dude... my audi has 1.8t and 167,000. it runs strong. Every single plastic hose and pipe will break at some point regardless of the car make.
2003 mk 4 jetta 1.8t 206645, running strong
Update! 180,000 miles... once you replace those hoses, the engine will last long
Was there a point to these statements. You do not buy a VW for reliability cut the bullshit. VW has had a low to mid reliability rating forever which is sad when Audi and Porsche consistently get much higher ratings. Fun to drive, yep. Relatively cheap maintenance with a few future proofing mods, yep. But please stop with the 200k miles and blah blah unless it’s a TDI!!, when the timing belts on 1.8t were snapping at 60k following VW’s 100k mile schedule VW did not say my bad here’s a new engine nope they said try and change them 75k miles instead. care to mention how the timing chain guides on the VR6 fail long before 100k miles yet the chain itself is usually maintenance free. The every car has issues is nonsense and purely denial from fanboys who accept poor quality as the norm. VW was not always this way but they have had plenty of black marks in their history, Reliability is just one of them.
If you want to extend the life of those hoses and pipes, open the hood and let all that hot air out after coming home. I do this with my BMW and was advised to do so by a BMW expert. I leave the hood open in my garage for hours. If you have to park with no garage...........?????
236,000 miles on my 1.8 the best thing to do is just delete all of these lines and the SAI system and cap it all off.
they really arent that bad of engines
No they're not bad at all
my MK4 Gti has 220K miles and running strong. Light weight pulleys, lightweight flywheel, New water-pump and Kevlar timing belt. Got the APR stage one chipped and Blue-line suspension. Fast fun and can go very fast lets just say autobahn style not quarter mile kinda fast but can get some good top speed and handling.
Super informative, thank you for the video!
Well, you got one thing right: "I don't understand". Not reliable? There are plenty of these all over the world with 200k+ miles, and they cost very little to maintain.
One very common issue is definitely the PCV valve.They..VW..put shitty sub par valves on this model.It's just a simple plastic breather type valve that eventually sticks.If you notice you're having to but a quart of oil in every few weeks and or the oil gets dirty quickly after oil change.It's more than likely the PCV.I got a Billet aluminum one,that I ordered thur 03 motorsports.It cost 38 bucks but damn it works great!
Do you have pics of how to install it?
All correct places of failure. Thanks for showing them all on an engine out of a vehicle. The good thing is, you can change all those pathetic hoses with much better reinforced ones. Custom made if needed. I'm going to be doing that soon as I get some oil vapor smell, definitely from some of the hoses you showed here. Those engines run especially hot in a very cramped space both not helping the hoses at all. lol
I have an AWP engine in my 03 gti. Its been upgraded to a K04 turbo, the computers been upgraded, upgraded APR diverter valve, lightened (vr6 single mass) flywheel, and a GHL exhaust. . Its been a great car so far...even with the aggravating vacuum leaks.
Would you know why a 1.8 t after a sai delete not wanna roll forward or backwards without stalling over 4500 rpms? Would it need the sai tune to fix it?
@@strongarcwelds4163 yes
own audi a3 1.8t 150hp 1997 and works great,same engine model.
Depends how much you care and take care of the car and engine :)
Just make some custom poly urethane hoses to replace the plastic ones that break. I used Y adapters to join some hoses together and havent had a problem for 6 years now.
If there is no code on the head it does NOT mean the head has been "gone through". A good deal of late model AWP engines didn't have the code stamped there due to machinery failure at the factory.
They are a strong engine.....but hoses a plastic valves should be changed., as you pointed out.But regular maintenance and correct oil these engines last.....i would say longer than most.
Can someone help me identify the hose he's talking about @2:45 please
Just hit 300k no issues
Well. Yes, I have replaced quite a bit on my 1.8T. However at 357 xxx km's. Pulls better than when new. And still reliable. I believe the body will rust out before the engine dies.
Every plastic will break, it's the same problem on all cars because of engine temperature and time. I have that problem on my 1.8t. For other its a really good engine, affordable and no many problems if you take care of it. Some will say head gasket failure or turbo failure but it will depend of the driver II think
My 1.8T has187K without any major problem but strong; check and change engine oil every 5 to 7k !
mine has 340k and it's still a champ changed zero hoses
bull crap. There is no way those hoses will last more than 100k miles Maybe the hose fairy came to you in your sleep.
@@ihatecountry Where he lives can make a big difference.
Ive heard alot of bad about 1.8t engines as a daily. So i went and bought and Same 336k and counting. maintenance does alot. St
I've replaced just about everything you said. It still didn't leak any fluids.. I've had the car since 53,xxx miles. And it now has 148,xxx..
RUNS GREAT I MENT TO SAY!!
I just replaced my crank case ventilation hoses at 236,000 miles. They were just rotting away.
I Love my MK4 golf but the location of some of the parts is infuriating they have many things in hard to reach areas and a lot of little things always go out, even with proper maintenance, speaking from experience, so they're a little pricey in the long run but otherwise great cars.
at3:40 it's not egr, it's a kombni valve that is electronic controlled.
The problem with this engine….. ECU!!!! it’s way too sensitive for the engine. The ecu is built as if the vehicle will be driven indoors!!! The way they calibrated the ECU was ridiculous…. It tells the vehicle to commit suicide with certain issues and other issues it tells the engine to run harder…. The ECU was built for one of those mini cars for kids… but they never put them on….
I’ve had every one of these problems on my 2001 1.8t Jetta. I bought it brand new and within the first 9 months of ownership it was back at the dealer 3 times with different warranty issues. I still have it and drive it nearly every day but I’m unlikely to buy another VW because of the stupid problems and total lack of maintenance planning by the designers. In fact, the dealer where I bought it offered a “free oil changes for life” program and I regularly took it to them for oil changes because, well, it was free. Eventually they “phased out” the program by making appointments extremely hard to get and very long (like 3 hours for an oil change) so people stopped going. Only after years of dealership changes did I start doing my own again and discovered that the entire bottom of the engine is covered by a two piece shroud. To access the oil filter they both have to come off. Thing is, the dealer tossed the aft shroud sometime over the years and never told me. Presumably because it’s such a pain in the butt to disassemble the car to do some basic maintenance. Removing the plugs also has multiple layers of unnecessary brackets and sensors covering them to remove that could have easily been put elsewhere. I also own a Honda and can change the oil filter without getting under the car. And it doesn’t drool oil all over the power steering hoses like the VW. Consider me unimpressed by the VW.
My Passat B5.5 now on 174,000 km and running strong. Yeah sure hoses and plastic pieces deteriorate, crack or wear. But as in any car you have to give maintenance and follow the recommended mileage. Some parts really go well beyond the supposed manufacturer service life, others break earlier, like diverter valve, pressure recirculating valve, bleeder valve, jet suction pump and secondary air pump. I may not say this, but I haven't changed the timing belt, it's the original from factory still running. Change engine oil before what the book says and in those turbo engines, better be synthetic oil to avoid sludge. As I said, everything goes to prevention. If you act over correction, well then the engine and car is doomed.
mine has close to 400k runs great ;)
Are serious man? 400k? Did had any oil problem? That’s a huge number!
My friend also runs like 350k and only now he have like a small missfire
One year later update? 😁 still running?
I have a 2003 gti 1.8t with only 130k😅
3year update still running strong
Would you know why after a sai delete the car not wanting to roll forward or backwards without having to stall the car more then 4500 rpms and it barely moves? Is the tune needed for the delete to fix this problem??
Personal issues buddy. History speaks for it self.
what is that last thing on the video, that pump?
cool
1.8t is the most reliable gasoline engine vw ever made! cannot agreed with u on these vid bud
212,950mi. on my '03 1.8T
AWP w/ EHA 02J...
Great engines...tough as fuck!!.....
I just hit like for all that shaking action at 5:40
Ps i got agu engine, and has no such thing on it😉
i have one of these engines in my 01 audi tt and they are insanely good engines! it has 147k on it and i have never had a problem with it. i mean yeah i have had a cracked line but um its a 15 year old engine..
that one hose at 2:49, yea, I accidentally looked at it and it fucking shattered. then I went to the junkyard to find another one and guess what, they were shattered too.
chris griner what’s that part called? Just making sure
I got a 01 wolfsburg jetta . Original clutch no problems ... btw 02 to 05 awp have KO4 turbos not KO3s
99 to 01 have the ko3 the 02 to 05 have the ko3s the audi tt 225 has the ko4 lol
why are u not on the forums!!! you could of safe people so mush problems!!!!! JK been there done that. really it suck!
i have a 2000 passat wagon 1.8t ATW engine code. any videos??
03 and still running strong for me. Maybe stop using cheap Parts
what is the diffrient about aup and baf，my mk4 bora is made inchina Engine code is baf
thanks man!!
Not too reliable. This 276,000 mile GTI 1.8T owner respectfully disagrees. The motor is the most reliable part of the damn car.
I didn't think emissions parts worked on VW's.
+1970chevelle396 they must work for testing purposes lol
Complexity 😂😂😂
can one replace a bjx motor with a agu motor
Should the crankcase ventilation tube that you pointed at be shaking while the engine is running
Bro how often do you check your comments cuz I gotta question on a part that is directly to the left of index figure at 2:52 in the video
PVC hose
Hey good stuff...we have 1.8 T and Wolfsburg edition ? Jetta...got check engine light got code to replace sensor under..behind manifold... but help I can’t find the replacement fuse..not fuse but something that moderates combustion.checked the before and after catalytic sensor..o2....the part I ordered is not any of those...any ideas....we are in mexico...Jalisco...and mechanics are hard to find..thanks if you have any idea....grant..
The n75 valve? It has the small hoses connected to it
Or did you mean the secondary air pump? It has a relay on the firewall under the black cover.
I got that stupid PO411 secondary air pump code... Stupid piece of plastic shit lol, what could be the problem? Is it the pump itself or is it a hose leak? I think i hear it on cold starts. But on cold starts the engine sounds kinda rough and i hear buzzing
It's also the crappy seals of the 2ndary air pump, just do the delete
Yeah I don't agree these engines are fairly reliable tbh very good to tune and i have seat with auq engine at 180,000 and it is absolutely solid, alor of the time when people always say certain cars are unreliable it's myths it's just cos people say it then people ear people say then they keep saying it when most of time never even had one, same with fiats I admit small engine fiats are pretty weak but fast fiats 2.0 16v turbo 2.0 20v 5 cylinder turbo. 1.8 16v fiat engines are genuinely some of the fastest and most reliable engines iv ever had and seriously serious fast . And good to tune fiat 90s engines wow! And pre 90s and modern ones to, fiat own Ferrari Alfa Romeo lancia and the rest, they've been one of the best car companies in history and made some of the best rally cars in history.. and same with a lot of other cars that people call unreliable and I know that rant don't mean much cos you probably didn't get them fiats in America lol Probably just Europe but if that's the case, that's why fiat is underestimated so much cos people have never experienced a proper fast fiat.. unreal fast..
This video really tells the tale lmao
Can you get in trouble for having a crack pipe in your car?
i am me how?
WhatTheFox I just bought mine and it’s giving me so much trouble i am about to set it in fire 🔥
Problem: hesitation during acceleration struggles to pass 3k rpm sometimes it does with a lost of power feels weak.
I replaced,
Maf sensor, n75, n249, coolant temp sensor, clean the throttle body, egr and other electric sensors. tight all the clamps clamps, I’m bout to pull my hair out of my head it’s also the TURBO S THE ONLY REASON I BOUGHT IT. any help will be appreciated
Coded showing is for n249 malfunction valve. and bank 1mixture adaptation lean limit not reach
Had same check fuel pump pressure ,injectors or fpr
Ive heard a clogged cat can cause hesitation problems, you could also have a bad MAP sensor. its located 7 inches down from the throttle body.
Check your coil packs!!
What’s the rubber or plastic hose called he touches in first few minutes
Pcv hose
Or crankcase breather hose
What oil would you recomend
5w 40
This guy knows shit about the 1.8L AWP engine. I have this engine with 150,000 miles on it with a stage 1 plus tune and it just hums along. Regular oil changes (Synthetic 0W-40 only), a good catch can so you're not blowing oil saturated air back into the intake and timing belt replaced every 50K miles. Sure, I've replaced various hoses, thermostats, but it is a great engine.
The part at 1:25 what's it called. I've been searching and can't find the name or part number

Hi guys, i have golf 4 1.8 turbo and i have problem with oil red light.I turned off engine and start drive again and oil light off?What's problem?Thanks 💪
You have synthetic oil?
@@canadacatalyst I have castrol magnetec 10w40
A have 1.8t auq... I think i sell this car:( is really bad?
Ive done a full rebuild of one of these
Mikey after a timing belt change i connected all hoses back to fluids and out serpentine belt back on started it let it run and sounded good then my temp gage came on and threw my serpentine belt off and the then the car wouldnt start on my golf mk4 if uno anything that I might of done wrong please help if u might no the problem thanks
@@BIGGLENNGODSSOULJA ill pm u
Glenneddy82@gmail.com email me man thanks
Anything good about they engines 🤔
Well, they stopped selling diesels in your part of the world now, because they lied with the emissions test, so you might as well get used to those overly complicated gas engines ;-)
(By the way, this cheating and lying business is legal over here, which is why they can advertise and sell a car with "4.5l/100km" while when driving it, you will never get it below 6.5l/100km. It's all because in Europe, they paid for the laws to allow them to lie.)
Yeah... uh... that.. uh is uh a mk4 uh vw
Sorry man, but if your shop be that dang dirty no matter you have problems
My 1.8 stage 2+ running 22psi has Ben good for 70k haha. Fck a diverter get you a bov
i have one
This engine i soooo Shit... Really bad head and problems miss fire and vacum xd
Look after it and change parts that need changing and it won’t happen
Man I really tried watching this. The Canadian accent is one of those I just can't stand
instant dislike for diesel preference ;)
