Hello,


I have another Parking Brake Malfunction. Same code as snapdragon had at the beginning.

Address 53: Parking Brake        Labels: 4E0-910-801.clb
   Part No SW: 4E0 910 801 A    HW: 4E0 907 801 
   Component: EPB  AV1C1010   H01 1010

- Both 30A fuses near by battery are OK.
- I bought a new motor to the left side but that didn't help at all. Also tried to install motors to the different sides but still problem stays at the left side. Just wanted to make sure a new motor is not broken already.
- I measured with a multimeter a whole wire from motor to control unit and its OK.
- I bought an used control unit with part number SW 4E0 910 801 D and installed it today but still, same fault code.


I have not changed a caliper, but it doesn't make sense to me how it would make any difference in this case, when fault code says "Electrical Fault in Circuit"?


Does anyone have any idea how to test further?
Is there any tricks what i should try with VCDS?
I haven't found any relays or fuses to the EPB except those two 30A in luggage?


Thanks.
