Worth getting that oil change done, gives you piece of mind. 034 Motorsport transmission mount is a really easy, cheap mod and smooths things up a bit more.
Sounds like a ballast issue with the light, I,ll second that the Osram bulbs make such a difference. Not cheap but worth it. Good luck...
I originally purchased my fog light grills from the A5OC forum but a kamikaze pheasant saw off one of them.
Got the second set from eBay and no complaints for a 1/4 of the price.
I’m not sure if the original rings will fit but I thought xenonz used to supply.
Never seen a bad review for them
of course you will need to do the foglight grills as well
