Engine vibration on 1800-2k rpm when accelerating

[Priit]

Hello.
I have 2012 citröen jumpy 2l turbo diesel 94kw.

1 day i had oil leak at engine and went to car repair. Then they told me that i have to change new clutch also.
After repair 2 days later i felt little shuddering/ vinration on engine and inside car around 1800-2k rpms when accelerating. And couple of weeks later shuddering went more bad. If i accelerate smoothly then its fine. Now ita on pretty much 3-4-5-6 gear. On 5th i feel and hear it loud and 6 th its pretty bad . So i went back to repair and they changed both drive shafts left and right but problem still exists.
They sayd they dont belive that problem is in flywheel (single mass flywheel) because it looked solid if they put a clutch on there.
So i went to other guy he put computer to my car and it showed dpf problem. But also there wasnt any smoke coming out of car.
Can you guys help with ideas?

thank you

Welcome to the forum, If the car didn't have the vibration before it went in and has the vibration after the 'repair'. The vibration is the result of repair ie something has been knocked, not fitted properly or the repair has not been done correctly.
Has the correct clutch been fitted to the car, correct transmission fluid been used and filled up to correct amount. Basically anything which has been removed and fitted back on the car and not fitted correctly could cause your problem.

Good luck
