210 is a little low, but its consistent in all four, so I'd go with a leakdown test now. Or perhaps a running compression test.

Not to challenge your competency, but did you do the test yourself? Just surprising to get 210 even in all. Or was that a general number being thrown out?

210 across the all cylinders and i had a good shop do it for me for 40 bucks, (they did it twice)
the shop is called ccb and they got a 650 audi s4 and a 550 evo 10

they said that i should be fine if its every now and then but if i start to notice it more its a bad sign, and its probley a head gasket.

typical sign of a head gasket will be coolant mixing in the oil or vice versa.. It could also just be the test pipe not burning what the CAT would burn. You have an AP1 which is set to run more rich than later models and also burn a little oil. If this is coolant it will have a sweet smell and is steam not smoke. There is also a possibility that you have a valve seal(not a vale seat) allowing a little oil into the exhaust.

If you have a blown head gasket and you are mixing oil and coolant it will start to turn your oil into a chocolate milk color and consistancy. Something to keep an eye out for. But in all seriousness I would lean more towards it just being the testpipe

i check my oil very frequently and the color is good. so i think its just the test pipe. my coolent level is not going down, and my oil is burning at a good rate. just kinda weird.

but thanks everyone!

Invidia states that the TP may show some white exhaust until it gets 'burned in.' That should be within 1000 miles (usually a lot less). I think I had it for a few days before it went away (could smell the chemicals burning too).

I would keep an eye on the coolant and oil as well as the exhaust. Have you checked under the car to make sure nothing is caught and getting burned and only appearing like exhaust smoke?

dang i've had the tp for about 2500 miles or a bit more. never really check if something is burnning. Its not a burning smell. but ill check just to be sure! thanks a ton

you may just have a small leak in your head gasket, so you won't notice the coolant level going down much. if the white smoke doesnt go away, i'd be safe and just change the head gasket. when driving it hard, it could really "blow" and then your car could suffer a lot more damage
