I’m having an issue with the rear drivers door.  Sometimes it will not unlock.  Sometimes it will not lock even though the car tries once it goes above a set speed.  There is no issue shown when I check OBDeleven.  I do get a fault though shown for the rear left door showing an implausible signal for the lock unit for central locking.  Looking for some advice.

 

I have changed the battery to see if there was a battery issue and no difference.

New lock mechanism required.

I thought that might be the case.  Skoda has quoted over £450.  Other garages have said the part can only be purchased from Skoda.  Anyone know if £450 is good?

It depends on the level of lock fitted. Can be purchased from €80 to €200+ for the part.

Fitted one to my OSR door during the summer for same symptoms. It was more or less £250 from TPS for the part.
