Had this on my e430 a/garde few years back same result found inside of tyre flexed rubbed on suspension under load cornering mine was more on front than rear tyres
I have used cks on several occasions and had no problems found that they are polite and information correct as said there are two sides ps Ihave know connection to cks only as a customer
Hi I was informed that after change of air filters on e55/e63 star has to reset engine management system however I don't think this would cause cutting out of engine
Hi think you will possibly find this is part of MB recall notice they failed quite often check if still applies to your motor believe applies to s class and e55s 210/211
