Hi i have problem with my c257 cls 350 4matic,
Car runs fine until i dont step harder on the gas , engine try to kick in but its jus a weird whistling sound (like from back exhaust )and car goes on kind of limp mode hi revs from 2000 to 3000 rpm on gears , paddle shifters doesnt work , check with carly and error code is (P238096 Generic communication fault code). Not any warning lights on dashboard , after restart car back to normal as long as i dont try to accelerate harder
Anyone know what is it ?
Regards
