    Weird noise followed by T/C light flashing

    Ok...... my car 2001 coupe turbo.... it has been making a sort of deep groaning noise now and again when i start it up and leave it to warm up, then the T/C light starts flashing with it, and it goes away after 2-3mins. but it will come back again 5mins later and do the same. the noise sounds like its coming from the back of the engine but thats just becasue im sitting in the drivers seat? i havent a clue what it could be? anybody got any ideas?

    The TC sensors must think your wheels are spinning mate, that would explain the speedo going nuts on you as well. Only experience ive had of this is with an audi a3 one of my mates hit a curb in, did exactly the same after the accident and he ended up gettin a new front corner. Looking at the car and driving it though you would not have known what was wrong with it.

    yeah sounds wierd mate but with your TC light telling you off and your speedo thinkin the wheels are going round sounds like somethin in between the power from your engine and it going on the road is spinning without connecting if you get me. I dont know enough to help further sorry, does it drive ok? still all the power you had etc? can you set the wheels spinning?

    yea i get full power, the TC is very intrusive tho?? it only flashes on and the needle moves when the deep groaning noise starts. its not every day tho? its now and then? so if i was to take it to a garage then i bet it wouldnt do it!!
