Question about the Audi

Mar 28, 2007 23 Replies

Ok i have a slight problem, thought i might throw it at you guys first.....



The 1.8t is now reaching intersteller miles and I just had the cambelt / waterpump / aux belts done, I also had the rocker cover gasket replaced as I had a slight oil leak, but I now have another problem.



I am thinking head gasket, but what do you think...



Still got a leak from the engine (hard to see where its coming from) but not from rocker cover now....



Smoke (grey) coming out of exhaust at slow speeds, noticable from behind



A new "whisteling" sound at low revs before the turbo comes in.



Slight hesitation when pulling away or changing gears but not really noticable.



Car still drives fine, turbo still pulls great just had 60 quids worth of NGK spark plugs but the smoking and other things are worrying, any ideas???



Over to you :)


I should also say, no mayo anywhere, and no oil in header..

Sell it and buy a Fiat Tipo or something nice and reliable - a Renault or a Peugeot perhaps? I've got a K plate Polo you can have for a few hundred quid.

Hmmm, turbo on it's way out, I reckon.

Check all the pipework under the bonnet, intercooler pipes, vacuum pipes, anything you can find. Otherwise it might just be a tired turbo.

Your local garage can do a very quick test on the coolant for products of combustion. That will tell you quickly if there is any evidence of a blown headgasket - from that perspective.

Hmm I was thinking turbo too, but it's fine, it pulls great sounds quiet and is actually pretty good.

Could this be a K04 upgrade time?

Could be, I've owned turbo stuff that has smoked a bit but run fine for ages. Just keep an eye on the dipstick and drive it as normal.

As for hybrid turbos, I've never seen the point on a road car.

Sounds like the turbo to me too. Is it using any oil? Might just be the seals?

Blocked breather pipe could explain all of the symptons I reckon.

Tired valve stem seals if the engine is high mileage could account for the smoke too.

Or, as others have said it could just be the turbo.

Maybe start of the turbo seals failing, and some oil weeping past? Maybe stem seals but that wouldn't explain the new turbo whistle.

you can't seriously mentuon renault and peugeot when also telling him to get something not only nice but reliable! surely they cancel each other out on the 2 makes? on the plus you'd give less of a s*it if a renault or peugeot broke i guess...

Apparently if the HG is gone, air can leak out causing a whistle noise, ?? true or not??

Tilt your head back a bit. See that thing flying over, that's called "irony" that is :)

Not heard that, bubbles in the coolant, mayo in the water, or loads of white, not grey smoke (and I mean loads, not a bit), overheating are all HG symptoms. If it is a waterway that has broken through, you plugs may have steam cleaned themselves. One plug cleaner than the rest can be a symptom.

it's chipped isn't it? I'd bet on something internal to the turbocharger - mine in the S60 got noisier and more oil-thirsty as it went on but performance never suffered.

In the case of the cars listed above it's more iron oxide than irony.

IIRC it's not chipped, just had the trial?
