    Quick throttle body question

    I want to take my tb off for a clean. Is it really necessary to replace any gaskets or can you get away without? Would it benefit from a clean? I wouldn't imagine it's ever had one...

    as above, but if you really must take it off you should really use new gaskets as the old ones will have deformed/squashed, and run a throttle body alignment with vagcom once its put back together...

    I hear what you're saying and I agree but I think there may be the beginnings of a problem with it. The revs have started to dip below idle a bit when I pull up to junctions etc. Also I have a problem I detailed here >> Odd Idle Problem Think I might just try an adaptation first before I go pulling it to bits unless anyone can shed some light for me

    What do you mean clean the throttle body? The inside around the butterfly valve? I hear of people doing this all the time, I think it's a ridiculous idea. Unless it's full of carbon which it won't be. Bad idle can be caused by air leak, maf, spark plugs, dirty injectors and a few other things.

    Ok just to update....
    I didn't bother taking off the body. I just took off the pipe and squirted a bit of carb cleaner up the body and wiped it out with a rag and got loads of black crud out of it and took my time making sure I got the butterfly edges as clean as I could. I then ran the alignment with vagcom. When I first went to meas block 98 the end field said ERROR but after I ran it it said ADP:OK.
    Seems Problem solved....so far
