I am having issues with psm, start/stop, 4wd faults on my 2014 4 which happens quite often - usually goes away when I restart. I've sent it tiwce to Porsche of Delaware and they just said my aftermarket 22" wheels are causing them. My warranty is about to run out in October so wanted to get another dealer to check it. I've heard bad coils can cause these series of faults so wanted to get another set of techs to look at it.

Any recommended dealerships I should go to? Also let me know if you have specific techs you trust, appreciate the help and thanks in advance.
