Hi guys quite new to this forum but any help is great,

Basically got a 2012 A4 B8.5 161bhp 2.0 diesel.

When I take off in 1st gear only the car shakes/shudders really badly. This only happens when the car has done a long journey.

I leave for work at 6am there is no shudder all the way there and back, 40 mile journey in total but when I get home and go out doing abit of start stopping, after about 1hr/1hr 30mins of driving the car starts to shudder on take off unless I Rev higher than usual.

The car has been in Audi Liverpool and I've been told there is no issues but they only do a 30 min test drive and the problem only comes after atleast 1 hour.

I tried taking it after it was doing the shudder but they don't look at it straight away and it cools down and doesn't have any issues again so I'm stuck

Has anyone else had this issue?

Thanks any help is much appreciated.
