Help - Electronic handbrake errors Mk4 Leon FR 1.5 TSI - P062F and U0121

[C_ED_99]

Could the forum help?
We've two Leon's in the family, and hers had been running fine. Last night it was driven a couple of miles to a family members birthday party*. On parking it was fine.

*It was a short trip, we didn't hit any potholes or have any other concerns or issues with the car

When we went to leave the dash lit up like a Christmas tree (see below)

The main problem is the electronic parking brake is locked on, so we cant move the damn thing to even take it to a garage.

With so many errors I'm guessing one of the (E)CUs has an issue?

I plugged an OBD reader in there now and got two codes -
Current Fault P062F - Internal Control Module EEPROM error
U0121 - Anti-Lock brake system control module no communication - though on turning the ignition off and on again this "cleared" itself

Is there a way to force reset the handbrake?

Any advice appreciated as the car is July 2020, so just out of warranty

You might want to get your battery checked before doing anything else.
Weak batteries that are about to die can lead to all kinds of control unit faults, which got cleared when battery replaced.

Update - Battery changed and rear wheels removed to reset the handbrake.

Car is still dead and sitting in the garage
