ESP FAULT. RUN FLAT INACTIVE. HARD STEERING
I have a c63 2008 amg. It had no warning lights other than it had got heavy steering with no whines. It’s had a new pump and still no difference. Put it on diagnostics and showed the following code :
5075 - solenoid valve speed sensitive power steering - permanent
so I replaced the speed sensitive valve on the rack and still got the same code and no difference.
Driving today and esp inactive and run flat inactive popped up. Put it on scanner and got this code :
5506 brake light switch - permanent
replaced this switch too on the pedal and still same lights on dash and same code coming up. But the brake lights still work.
What could be be my issue ?
Thanks
