ESP/BAS trouble
the car seems to be OK and after some time (could happen in a few seconds after ignition or hours after), the warning light start to flash. If you touch the brake pedal, there are intermittent wheel blocking. after a few attempt on the pedal, the BAS/ESP light stay on. when the car is off, the BAS light disappear and the problem come again after a few time. We tried to retrieve the default code and I got a C1120 ; C1140 ; C1141 and C1202.
I would like to know :
1) if I can have an emergency solution to drive more safely without the wheel bloking issue ? someone told me I can remove the ABS pump relay somewhere but I don't know where I can find one
2) if you know what can be my problem and where to look to solve it
