Speedo prob is fixed. Still having bad noise and vibration under load and especially in 5th gear at 80kph. it seems to ballace out at 100k's though, and at lower speeds there is a metallica chinking or rattling sound.
Cutch??? Flywheel???
2001 Td5 110. 185,000k's on it.
HELP????\
Hi I am also getting the same sort of vibration. 93 TDI Disco with 107000ks. The vibration is not there all the time but disappears mainly at about 100kph. Yes and it does it at rest too. I will try engine mounts later and maybe the harmonic balancer. I will advise on the progress.

You'll get used to it, mine has done it from new and I think it is to do with the harmonics of a five cyl engine. I hardly notice now after 6 years. The tinny sound at about 80 kph is a vibe from the exhaust in my opinion.

I also get this vibration in the engine at 2200 - 2400 rpm, whether in gear or neutral. It has been apparent in some form since 60,000 Km's when I bought it. New engine mounts settled it for a time. Seems like a common issue.
I just bit the bullet and replaced the dual mass FLYWHEEL. FIXED THE SODDING VIBRATION!!! It was buggered and had heaps of play in it. A big expensive job but its sorted now. I got a new flywheel for $390 and a clutch kit for $318 and labour $450.The next day I went back and had the engine mounts done as well while I was in the mood. Two mounts from a Trannie write off done 10k fitted for $150. Loads of people say this helps and it is generally smoother but it was not the cure for the big vibration I was getting at 2500-3000rpm. There are still some harmonics coming through mostly I feel from the exhaust (goodbye cat) but they are so mild as to be irrelevant. It has transformed the vehicle and feels like a totally new car. Hope this helps
Good result.
$390 for a dual mass flywheel (and that'd be those NZ dollars as well.....)sounds pretty cheap to me! I thought they were a lot more expensive than that.
Yep is is cheap. I have spent a bit with them over the years and they also wanted to get to the bottom of the issue as well. Other vehicles they deal with have this problem but nobody wanted to fork out the coin in case it was not the cure. I think it was at cost or close to for the flywheel. My clutch was knackered so I had to get in there anyway.Quote:

Mine could be the flywheel but as the engine gets instantly smooth and more powerful at about 2700 (somewhere between 2650 & 2750) I think it could be a change point in the fuel timing map that could be better programmed. I can't imagine that a faulty/worn flywheel would suddenly become balanced at a specific revs. I will in time remove the starter and check the flywheel for movement though if my clutch problem persists.
Hi, any update on the flywheel? Vibration cured?
The engine has lost most of its roughness since removing the big I/C, so I think it was the particular combination of the ecu remap, the I/C and possibly the improved intake and exhaust flows. Its also lost a significant amount of its willingness above 2500 rpm, although still a lot better than standard.
