I've noticed that if I'm in 5th or 6th gear on the motorway & I'm not going particularly fast (say 55mph in 6th) & I try to accelerate hard I get quite a lot of shudder. It was quite bad this morning & it felt like something was about to break, so I accelerated a little more gently.

At idle car & vibration noise is fine & pulling away seems ok. So, I'm not sure if this is the first signs of DMF failure.

Got Clutch replaced by Unit 18 about a year ago & they said DMF look fine so didnt replace it.

So hopefully its not gone as that would be a pain!

Yep sounds like it

bugger!

Mines has done that from day i got it 6 munth ago and bein mapped 3munth stil fine i find after 60mph in 6th its fine it doesnt like hard accelerating below that in 6th same for 5th below 50mph hasnt bothered me tbh i make sure im above these speeds on the very rare occasion i floor it both my mates jetta and ibiza deisels do this aswell both standard

The thing is I dont think it 'juddered' as bad before. I could quite happily boot it in 6th at about 50mph & not have any bad effects (didnt do this often as i know its not good for the clutch/engine). But now it really judders.

Is it mapped? I wouldn't be trying to accelerate hard in 6th at 50mph. Change down a gear or too

Yer thats just lazy driving really. Drop it down a gear and it might save you a bill.

Never felt shudder too badly until I took a trip out in vrsJoe's the other week

They just dont like foot to the floor low speed high gear as said drop the gears

haha

Sounds exactly like what JoshH witnessed in mine. It's very easy to drive round it, even at 50mph in 6th it's fine as long as you feather the throttle.

Mine started doing exactly the same about 2 weeks after I bought it. If I floored it in high gears from low revs, if would judder big stylee between 1700 and 2000 revs. Just changed it for a solid flywheel this weekend and no more juddering. I don't think my DMF was far from exploding considering the amount of play it had when I removed it.

Change down guys!

Pretty simple really!

Thanks for the feedback guys.

I know everyone is saying to change down - I normally do. But it doesn't solve the under lying issue: does my DMF need replacing?

Generally the car seems to drive well, it accelerates well in low gears, there's no judder. At idle it ticks over pretty smoothly (for a diesel) & there's hardly any vibration or rattling. The problem only seems to occur in 6th gear - above 65mph it seems fine, but at 55/60 mph its really badly juddering if I accelerate hard, which I'm pretty sure it didn't do before.

And btw - its remapped with a generic Angle Tuning remap.

Yer thats just lazy driving really. Drop it down a gear and it might save you a bill.

You will have DMF issues if you try and accelerate hard in a high gear.

What he said, don't look for trouble you don't have yet.

With a remap on it you really want to be dropping a few gears

The vibration is just the sheer amount of torque the flywheels trying to cope with!

It wont be goosed yet but if you keep going like you are you will run into trouble sooner rather than later, im surprised your clutch isnt slipping.... Yet

If it only does it at <60mph in 6th, just drive round it, as said, you dont wanna be doing that anyway.
