Car juddering at low revs

matlob · 2024-12-03T15:50:39+0000

Hi. Looking for a bit of help if possible

Have an Audi A5 2.0 tdi 2011 and it's started to judder and shake quite a lot when at around 2000 revs. If I dip the clutch and increase revs the juddering reduces.

The clutch operation wise seems fine. I turned the engine off and coasted down a small hill and the judder was still there so not sure if it could be related to the wheel or if it's the clutch it would still be noticeable with no engine running. I've not done any clutch oil changes

It does sound mechanical and even at tickover/stationery it doesn't feel right.

When I first drive the car it's fine for 10 mins but then got progressively worse and the judder seems to come and go

Thanks for any help. Car is on 120k so maybe it's just starting to fall to bits

Dual Mass Flywheel?

Thanks Mottie. I'm thinking clutch related too. Would it still jerk when the engine isn't running.

I had noticed that when I released the clutch I would get a rattle at a certain bite point too. Shifting gears is still as usual.

I see a clutch kit doesn't include a flywheel. Is it best to too the lot?

Sounds like DMF I agree, but have you checked for any codes to rule out other possibilities

Is there any knocking or thumping evident?
I agree, a DMF is likely - unless there is a misfire. Any dash lamps on at any time?

Thanks. Drives perfectly for 10 mins and no lights at all. Then just starts juddering at low speeds and then again at higher speed. Gear changes have always been perfectly fine. No knocking or thumping.

Mechanic has mentioned a DMF to solid swap which would work out cheaper. He's not checked it out yet though

Time to get another mechanic. Rules is rules

DMF not DPF Stivino.

I must learn to pay more attention when I'm reading. TMA for me (Too Many Acronyms)

Hi, I've just ran a diagnostics and get the below error on the diagnostics

Bypass flap air cleaner valve - open circuit. Code P101600

and the below error on the dash popped up when ticking over

Stabilisation programme fault

Not sure if something else now causing the juddering.
