Audi A4 1.8T Common Problems PART 2

This video goes over some MORE common problems I've seen on the Audi A4 Quattro with the 1.8T engine. In the video we look over my 2002 A4 and talk about some past and present problems I have seen on this car. If you haven't seen part 1 check it out on my channel. Thanks so much for all the support, please comment problems you've seen on your Audi's!

Check your spark plugs. They can break in weird ways and cause the inner part of the plug to move with compression.

great video, very informative thank you for uploading. i have a b5 a4 so many similarities to your car.

i just recently got an 05 1.8t manual quattro and it has the tick and rough idle. the tick does go away once the engine has warmed up but the rough idle stays. been suggested to look at the engine mounts

Hey All, getting an 04 A41.8T soon so will be coming to the community and Stuie for all my advise, glad I found you guys and thanks for the Video Stuie, really prepared me for the road ahead with my new (old) car.

Hi Stuie. My 2004 ticks also and I suspect the timing is off marginally after a belt replacement but not sure. Anyways you make great videos, thanks for them.

The tensioner by default when broken in will be slightly loose at when the engine is off since its oil pressure driven along with an internal helper spring.

The ticking is fairly normal, it's the timing chain slightly knocking against the head cover gasket, rough idle I experienced for years and then only by chance replaced the breather and pancake valves, the car has been sweet ever since and has been like that for the last 5 years.. Annoying when trying to fault diagnose though, try squeezing breather valves and when you come to one that smooths out the idle, your culprit will be in that area..

[rollindeep]

Personally, I do also believe the car is not ideal in the very hot weather's you experience in America.. Plastic and rubber components do not bode well in extreme hot weather, mines in the UK and tbh, after initial teething issues, it's lasted 15 + years and still sounding sweet along with decent power, Common faults are coolant flange, pcv valve, the older ignition coils, boost leaks, plastic water pump and chain tensioner which disintegrates and clogs up the oil pickup tube located in the oil sump as well as the dreaded wiring loom in between the car door due to opening and closing over time. The manual Transmission very reliable, wish I could say the same about the automatics tho lols

I’m looking at picking up an 04 B6. How often would you say you’re actually having to wrench on yours? Looking for a fun daily.

[smackthatsolskinnsbolle]

Same sound in mine. And it was one sparkplug under the coil

[milkyway]

Звук может быть из за изношенной постели распредвала или самого распредвала. Это случается из за краткосрочных перегревов головки блока, которая очень чувствительна к этому, так же из за неправильного подобранного слишком густого масла. В корпусе масляного фильтра стоит маленький шариковый обратный клапан, который не всегда работает исправно и стравливает давление из головки блока при простое. Густое масло усугубляет положение.

I own the 1.8 Manuel versions have had timing chain busted and nothing else luckily failed except the bypass valve due to me turning up the e boost. Mechanic fried ecu doing engine work had to replace ecu at 100k miles. Having major coolant leak all of it gone after several miles used to barely leak now it’s exploding out. Was curious if the coolant flange was the result to that problem

[Calabrai]

how about the center console electical problems

[PCassotech]

Hey buddy that knocking is most likely from a piston, sorry to bring bad news.
Someone said chain slack but it should be noticeable at idle and go away once you rev up, yours is the opposite, bet you at higher rpm’s it get louder… right..?

[tomaszziomek]

Is this noise after replacing the timing chain and tensioner?

[steambuns]

hey man, is it true that u can delete the secondary air pump with a tune?

[tnoddy]

@stuiesgarage please could you assist, my A4 B6 leaking from the radiator and I suppose there may be a blockage in the coolant system and that’s the weak point or the water pump may have given in and that the blockage any advise would be appreciated. Too scared to drive it now.

[thatkidagain]

did u ever figure out what was causing that ticking? currently having the same noise coming from my 20th gti

[lolfix]

did you ever solve the tick? and if not got any more clues?

[XstremeModz]

Just watched your last video a few minutes ago. Just got an 02 a4 1.8t (not quattro) and been trying to figure my gremlins out.

Check engine light and red oil light, esp pops on and off. Have no horn (guessing fuse, I can hear it click in the wheel), door jam issue for window (driver), and a short of power in 1st-2nd.
At 90k, just had oil done and coolant res replaced.

Any advice
