Audi A7 3.0Ltr TDI quattro sport back black edition. When it cold and issues getting worse my car shakes the car hunting badly then clears after 10 minute then drive ok it's getting more frequent and I'm worried what it is.

Any advise would be veryf grateful or ideas.. Carly brings up Cambus about the exhaust not cooling correctly 2017 model

I'd recommend a diagnostic check to see if any fault codes flag up. Could be an issue with the maf sensor, injector or cam position sensor. 

Identical problem, sometimes starts ok sometimes rough idle, 5 mins it clears or if drive off straight away it drives fine and no more idle issues. Took to VAGTec great service but found no warning lights or real issues. Suggested I take back to garage where I had oil cooler replaced last year rather than them start to pull car apart. Fault is annoying me now
