    If it's 2003 mate, you need to be in the B6 section.

    a4 engine help

    This is the B6 section fella!!!!

    That sounds like they replaced the original 1.8T 190 BHP engine with the lesser 163PS 1.8T variant.
    Not sure what differences there are but that is not a good sign if u bought a 1.8T s-line 190??

    My A4 avant is a limited edition (non s-line, non quattro) 1.8T 163PS.

    I would not have bought it knowing that myself unless it was given a huge discount ?

    I imagine its still running the 190sline slightly larger turbo and management etc so will be a bit of an odd one power output wise. Im not sure what if any the internal differences were. If its running well i wouldn't panic too much about it, if its from a dealer i would consider sending it back though to save your self any potential headache.

    A 190PS should have a BEX code on the engine, if it reads something else then it will not produce the same output without some tinkering eg remap. Check to see if you have intercoolers at both corners for starters.
    The BEX engine is the same 1.8 engine but it has some strengthened internal components, dual intercoolers as well as bigger injectors and maybe some other things that I cant remember right now.
    What does the log book say? Also what month in 2003 is it? and is it a proper S-Line?
