Passenger door central locking

Hello I'm still here and enjoying my wonderful TF.

A frustrating problem though, my passenger door won't unlock with the central locking - it locks ok and unlocks manually but not with the central locking.
I had an actuator kicking around so I replaced it but yet the problem persists. I'm guessing the fault must be electrical - has anyone encountered this ?

( It was suggested it may be the BCU behind the centre console however on speaking to an expert it was thought to be very unlikely)

Many thanks as always

In BCU driven TF both doors are connected to same lines coming from BCU for central locking. If unlocking works on driver door with central locking then wiring (pink and orange wires) for passenger door should be imspected for continuity in order to see if you have some brake in the wires. You said you changed actuator. Was that good actuator?

Thanks for that, yeah the replacement was ok. I had wondered about the wiring so will check that out.

Check out www.technozen-electronics.com for info on the BCU.

I had another look today, removed the plug and scraped the contacts clean and sprayed with contact cleaner.

All is good now

Thanks for comming back with info how problem was solved!
