Collision Prevention Assist Plus Inoperative
2016 MB GLE350 I bought CPO back in June 2020.
Car has 40,200 miles.
No other problem since I bought it.
I am getting the error "Collision Prevention Assist Plus Inoperative".
Car works just fine but every startup this message shows up.
I remember few weeks ago car had to break to prevent collision.
Is there a way to reset it?
Is it due to cold winter and not enough driving?
Wife uses it only for 5 miles RT to work.
Thanks
Robert
PS: CPO ran out Jan 1st!
Cleaned the camera area in the windshield.
Error still remains.
Will see tomorrow if it goes away after driving a little.
I talked to the dealer and they want $190 or something for diagnosis fee + additional reset fee.
I am not happy at all.
There was no accident, just the hard breaking system did and now it's disabled.
Next time I have to get major service done at 50K I will get this done.
If anyone knows of a way to reset this let us know.

They charge $199 for diagnostics which I had to pay. They did not charge me for reset procedure
(maybe they felt bad that I could not use the $150 off coupon which needs $299 minimum service work)
