Collision Prevention Inoperative plus multiple errors
Some time ago, my car (2017 C205 220CDI) started showing this error randomly. It disaperas when car is turned off. Then one day, in heavy rain, error came and with it came few more error. Power steering, parking brake and few more. Since I'm under warranty, I stopped, called benz hotline, got replacement vehicle, and car was towed to dealership.
And they found nothing, car returned with no errors. Great. That's when I got first sense of electrial gremlin problem and started googling just in case. Today It happend again. CPI error, then power brake starts comming of and on in terms of seconds. Then Power steering. Important to say is I do not loose actuall steering or speed or strenght. Just random errors. I stopped the car, no one to call today, decide to try and get home, turn it on. all is good and drove next 20miles home with no error.
Now, I've seen members of this forum and over the internet posting CPI plus losing power, but did not find issue similar to this. I'm affraid if I do not dig really deep my dealer will not find a solution.
Anyone had similar case?
Could it be battery related? So strange that the service staff did not think of it. I was about to sell the car in the next 4 months due to family addition and I had it really long time now, but I want this resolved to sell car as its rest of it, perfect condition
Weak or fading batteries cause myriad unexplained electrical problems on MBs.
