Recently I've bought a 2011 CL63 with 90k kilometers , I've had several issues that I've dealt with on the past 6 months including ( Fuel pump replacement + Filter ) ,ABC pump replacement , Transmission Mapping update + Transmission oil change with some other tweaks here and there lol ( People here in South Korea don't exactly know how to maintain their vehicles lol). I went ahead this morning on drove the car after it stayed over night , the car shudders and vibrates + the transmission slips when the car is set on Comfort . After the car warms up , the shudders are way less , but it comes and goes with minor slips + ( vibrates when it comes to a stop if ECO is set to ON ).
Another issue is when I drive the car into a parking lot ( where it requires a lot of steering ) , there's a weird sound like ( Scratching / Rubbing ) that comes from the front end I guess ? I checked the bushings on the front but they look fine
If anyones knows how to fix those issues , I'll be more than happy to hit the road again with the beast

Cheers !
