Parking brake again

[Stuarta]

Thanks,

Will remove wheels and have a look after my night shifts the next couple of days. Unlikely to be corroded / moisture here - more likely dust.

BTW - yes, I did code the new battery and it was accepted.

In the meantime, is there any way of manually disengaging the epb? google has failed me on this.

Planning to get a new controller once I can get the damned thing mobile to collect it!

Sorry all - should be in the D3 forum - mods, can you move it or do I need to repost?

moved
Im sure there is a wind back tool for manually winding the parking brake on a D3 to back it off - DarrenJoe90 had to do it recently - check your user manual I think its like a z shaped allen key?

[Stuarta]

Thanks

Had a look in both the manual and the toolkit - manual has nothing to say at all about a procedure and the contents list for the toolkit has no mention - only possible suspects are the torx allen key and a plastic rod that's threaded at one end and has a couple of holes at the other but I suspect that's the "wheel mounting pin"

I suspect all but the first one are due to low battery and starting the car.

Clear all trouble codes, then do the Function Test:
Prerequisites:
Connect a battery charger as per repair manual.
Cycle the Parking Brake ON, then OFF first.
[Select]
[53 - Parking Brake]
[Basic Settings - 04]
Group 010
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]
The brake pads are now opening and closing 3 times.
Wait 30 seconds after the the brakes stop making noise.
[Done, Go Back]
[Close Controller, Go Back - 06]
Clear all codes again.
Do you still get EPROM error?

There is no way to manually disable the EPB, it has to be done electronically

Saying that it might be possible to remove the motor and manually wind the plunger back, but then that would throw up more errors and could cause the ECU to do a wobbly

Tried that today - after leaving the charger connected for several hours on a brand new battery - switch is ineffective (disabled) and so impossible to cycle EPB. All other functions requiring the motors also disabled.

EEPROM error is consistent and has been since I bought the car - didn't do anything about it as the EPB always worked regardless!

Glad I found your post again, today I had same problem. About two months ago I replaced both parking brakes calipers. In the meantime I spotted problem with battery and today brake malfunction both of them. My first feeling was OMG new parts and already broken can't believe until I've done scan. Scan showed this same problem" Left and right brake motor voltage supply - Electrical malfunction in circuit. Have you had similar problem, do you think that my poor battery condition can cause this problem with the parking brakes when engine is off. I will appreciate for your answer
