Shudder / Judder under load Golf TDi Mk5
Discussion
Hello all,
I've had this very odd issue on my TDi Golf for several thousand miles now but have no been able to successful in finding the cause. My car has done approx 70,000miles.
Bascially when the engine has warmed up from overnight cold and i'm at motorway speed in 5th/6th gear (worse in 6th), if I agressively build the revs from 2000rpm I feel a resonance/shudder through the car. I can only describe it as a rythmic shudder through the whole car (feel it through the seat) which begins to settle as the rev climb past 3000rpm.
Revs needle appears to pause briefly whilst this behaviour occurs but then the car will continue to accelerate with no problems.
It most easiest to demonstrate going up long motorway hills.
Diagnostics show now errors what so ever.
MAF sensor was changed and fuel filters to no avail. If anything using fuel additive has made it more obvious (my car does acceleate quicker since running that stuff through the tank a few times).
One workshop I took it too suggested it would could cost me a lot to diagnose going through the fuel system components to rule out and issue there.
I think its more something mechanical than electrical but i'm not specialist on this subject.
Feedback appreciated.

I had something similar in my MkV Golf TDI. I don't take it on a motorway during the test drive before buying it, but as soon as I used to go to work there was the shuddering. I only noticed it at around 60mph. Local indy looked at it & they found two tyres (I forget which ones) out of shape. They thought the tyres were run at too low a pressure & got too hot. I replaced the tyres & problem solved.
Experienced similar with a TDI 105 a few years back, but it only happened so occasionally and the car wasn't used on the motorway that much that it was never considered an issue that needed fixing. Have certainly read about it occurring online though, but can't remember if a definite cure was ever found.
edit - this was at 15k-ish miles on the clock

Did you find the solution?I have a very similar problem with a TDI Seat Alhambra, and my mechanic can't work out what's wrong. He has replaced one worn driveshaft & roll bars, but problem persists. Usually when it occurs the resonance / shudder is mild and you can accelerate through it, but on long journeys it can get severe and affects drive speeds from about 45 mph upwards. Shudder disappears as soon as clutch depressed, vibration is on the car floor but not steering wheel.

It's either the dual mass flywheel or clutch.I have a very similar problem with a TDI Seat Alhambra, and my mechanic can't work out what's wrong.

The bold would be a pretty big clue for me if I was trying to diagnose the fault.
Matt,
Thanks for your comments. Our mechanic didn't think it was the dual mass flywheel as it has been intermittent, and in the past only would occur on long journeys under load. How would you tell if its the clutch or the DMF?
More recently it has occurred when driving up hills etc. but it appears possible to accelerate through it. On long journeys it has got progressively more severe and affects a wide speed range.
Some history
The problem started off last summer when we were driving in the Alps on some steep hills under load, a minor vibration which would disappear when you got more speed up or the road flattened out. Not conscious of the problem for rest of holiday including some long journeys, but then it came back on the long motorway drive back home, and was quite severe.
Took it to our mechanic a couple of days later but absolutely no sign of a problem, so we forgot about it.
My wife took it loaded on a long journey and the problem came back in a severe way, so she called our roadside recovery. They thought it was the dual mass flywheel, but our mechanic disagreed. Our mechanic replaced a worn drive shaft and roll bars, and had no more problems for months, but then again did not do many long journeys or fully loaded trips.
My wife recently took it on a motorway journey including a steep hill in High Wycombe which seemed to trigger the problem on her return journey.
Any more thoughts would be appreciated.

My 06 Alhambra 90 k mileage also developed this same intermitant fault as yours about six months ago, it only happens on similar trips to yours and only occasionly, not able to diagnose the cause but seem's to happen in 4th mainly.

Currently my car has decided to play intermitant clutch fault, no clutch slippage or DMF flywheel vibration, however clutch pedal stayed depressed on leaving motorway, managed to fight it in to gear and get to my nearby friendly garage. it was sat for a few days then pedal pulled back up and it now seems to work fine and no tell tale faults with clutch or gearchange can not be found.
however replacing the master cylinder and bleeding system at present as it is a start and cheapest option after doing nothing which is frankly not an option at the moment. I am not sure it will cure this, I have my suspicions that the Gearbox shaft wear may have something to do with the problem in the end.
