Hey guys well i recently just started experiencing this issue with my car after installing a test pipe and giac x tune on my car. About a week ago my car would start to slightly smoke from the exhaust at idle for a lil bit then go away. And just a few days ago i just realized that from the back of my block there is light smoke coming from there too. Ive searched and searched but to no real avail. all ive heard is head gasket, pcv, and turbo seals. Im pretty sure it might not be a headgasket bc Ive checked and checked and i see no oil in my coolant or coolant in my oil. And the smoke doesnt smell sweet it smells like burning oil. I also checked my intercooler piping for excess oil that maybe the turbo seals might be blowing more oil but it looks normal. Nor do i loose much oil or coolant than normally. No overheating or running badly just only other thing im getting from the car is a po170 code. Really confused on what this could be. Anyone no what this could be and have any other ways to check and find out what it could be. Im new to audi's and kinda no clue else where to look or what to do so if you guys could help that would be awesome.. thanks in advance for your help...

 

It's getting cold you sure it's not condensation burning off? Otherwise it could be coolant coming out of the water jacket of the turbo

 

Well its only doin it after the car warms up. And I guess how else would I check for tg turbo seals

 

Anyone???
