    Hi all, ive just had my car MOT'd which i never thought would pass having a 3" full system de-catted but thankfully it did :)

    After the MOT was done i had to take it straight back as there was some knocking from the underneath of the car. Was put on the ramps and a long piece of metal wire was near my prop shaft, i presume it had flicked up off the road, anyway found the problem and it was the heat shield around the bulk head had been touching the prop shaft so i had it removed as the clips had broken and it was worse for wear.

    Later that day i was driving to the garage and noticed a high pitch squeak and accompanied with vibration/rumbling which you could feel through the gear stick and the floor, if i turn right the noise goes away but if i turn left then the noise gets worse and is like juddering/clicking type noise.

    My friend seems to think the prop shaft has been knocked and is unbalanced or something is catching it, i however am not to sure.

    Could it be the drivers side front drive shaft as i thought i saw the drivers side wheel slighty move back whilst the guy at the MOT station moved the car on to the ramps whilst steering left?

    Any help from you guys would be much appreciated

    Very specific description but yet I can't grasp what it could be from that......... If you got rac or aa call them out and lie say it won't start and it's knocking. Or get it booked in at a specialist as it sounds like it's not a minor problem and how we all drive s3's it could be dangerous!

    ive just had the car up on the jack and stands and was just underneath when i noticed 2 cables possible linkages wrapped in heat proofing hanging quite low and touching the propshaft. could it be the problem as there was a heat shield holding them up to the underneath of the car but was broken and came off on the mot??

    cant see the heat shield loss being much of a problem though as its only over the propshaft and cant see that getting hot although the exhaust does glow on hard boost but u have the outside air to keep it cool :s
