I am having all kinds of random issues with my car at the moment I have had it into Vag and they can't seem to find an issue , I was wandering if any of you guys had any ideas .
coolant leak drops from max to min overnight if the car has been drove ( nothing on the pressure test )
rattle on start up for a few seconds
ruff idle , car seats shake on tickover
stronic becomes clunky when the car is hot and there's a burning oil smell?

pressure test on the coolant system was fine?

anyone any ideas please?
