HarleyFDMD Posted May 12, 2017 Author Share Posted May 12, 2017 How far back is the noise coming from? could it be your prop shaft hitting the exhaust? Sounds like its coming from right at the back. Dont think itll be the exhaust hitting the prop as there is plenty of clearance Quote Link to comment Share on other sites More sharing options...
HarleyFDMD Posted May 12, 2017 Author Share Posted May 12, 2017 Sounds like diff bushes. Easiest way to check is to get it on a ramp, get someone to go through the gears and go on to do throttle whilst you stand underneath and see what's going on. Amongst a many things not already mentioned it could be diff hop due to knackered rear sub frame bushes. I think you guys are probably right. The diff bushes were replaced last year with superpro bushes however the ear mounts are shit. They are just little packers designed to sit inside the oem bush to aid stiffening it and i didnt think they actually fit that well. Im going to remove them on Saturday and see if that cures it. I also need to have a look at the diff backlash and see if thats excessive Quote Link to comment Share on other sites More sharing options...

HarleyFDMD Posted May 12, 2017 Author Share Posted May 12, 2017 Dampers knock when they fail Brand new meisterR CRDs last year. Only covered maybe a couple K miles. It doesnt knock over bumps, only when you first press the accelerator, and then again when you let off Quote Link to comment Share on other sites More sharing options...

Bayden_uk Posted May 13, 2017 Share Posted May 13, 2017 I had this exact same problem. In the end it turned out to be a crack in the break disk. Wouldn't really see it the crack was that fine. Get the wheels off the back and just have a good look. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted May 13, 2017 Share Posted May 13, 2017 I had a similar issue was the prop carrier bearing , bit of a clunk on/off power 100 euro for a new one Quote Link to comment Share on other sites More sharing options...
squiffy Posted November 9, 2017 Share Posted November 9, 2017 Was the cause of this ever found? I'm chasing a knock on mine with the exact same symptoms described in the first post Mine is a tt 6spd for reference Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted November 9, 2017 Share Posted November 9, 2017 i dont think its the exhaust unless there is something new near it, its solid that exhaust. The car is prone for smashing diffs, i did one on cadwell and one on the road, i may have done another but i cant recall. what your describing to me is not what ive had with the diff going, when the diff goes it will grind under hard acceleration or click and tick. - - - Updated - - - shit just seen its a revived thread Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 9, 2017 Share Posted November 9, 2017 This sounds like it could be the dual mass flywheel is worn out. You can check the play on a ramp through the inspection covers. The manual has figures for how much free rotation is allowable. Quote Link to comment Share on other sites More sharing options...
