Rear doors sometimes won't unlock, front only? Any ideas

Mike v.t.s · Apr 29, 2014

hi people not been on here for a while since selling my much loved p38 so I apologise, I do need your help tho.
I do have a customers L322 2002 model vogue that sometimes will only unlock the front doors and boot NOT the rear doors, but it seems to be random, also when I press the button or tailgate it opens the latch twice (fast) could this be related? I did hear water running in the glass part of boot as I lifted it up so need to clean the drains. Again could this cause the rear doors to some times not unlock with the fob? Any help would be much appreciated. Many thanks

Any body got any ideas? It's got to be a fault somewhere that makes it NOT UNLOCK BOTH back doors, as sometimes it unlocks them all.

Think the BCU controls the door locks

I'd get it on diagnostics and test them all out properly

Thanks hippo, I've plugged in with my snap~on solus pro but it doesn't come up with anything, where does the command wire come from that tells rear doors to unlock or where is the ecu for Central locking! I'm thinking that hopefully it's just a dirty contact. Thanks for the reply very much appreciated.
