TrumpieVr 10 Posted March 28, 2018 I know this issue has been cover repeatedly however to try and speed up the search process I could do with some pointers as to what the problem might be. The central locking will unlock from both doors fine, pump comes in and all is good however neither door will bring the central locking in to lock. The pump doesn't run there's nothing happening, the doors can be locked manually as can the boot, it this likely to be an electrical problem or a pump issue. I know this is a vacuum system but how does unlock differ from lock? if the pump and vac work to unlock why not lock, any help would be appreciated.

virtuoso23 10 Posted March 28, 2018 Strange one this, I would imagine the central locking is purely controlled via the pump. Quote Share this post Link to post Share on other sites
Dox 23 Posted March 28, 2018 (edited) The locking rods inside the doors operate micro switches in the vac pods when you turn the key turning on the pump to either lock or unlock dependant on rotation of the key. The easiest place to start is the pumps connector on the boot, check for corrosion in the plugs. https://www.ebay.co.uk/itm/45-Vw-Corrado-Door-Cental-Locking-Solenoid-Actuator-Motor/222871508490?hash=item33e42d560a:g:Zy4AAOSwTM5Yx84b Edited March 28, 2018 by Dox Quote Share this post Link to post Share on other sites

TrumpieVr 10 Posted March 28, 2018 Cheers Dox for that, super help, where in the boot might I find it? Quote Share this post Link to post Share on other sites
TrumpieVr 10 Posted March 28, 2018 Don't worry traced to right side of boot.👍 Quote Share this post Link to post Share on other sites
1xshaunx1 27 Posted March 29, 2018 If it’s not that it could be the soldered joints in the door that goes to the actuators There are a few threads on this. Unravel the sheathing to see if the joint is still good and not corroded. Follow it along the bottom of the door and unravel upwards three red wires are soldered together or should be.

TrumpieVr 10 Posted April 4, 2018 All fixed 😁, traced wiring back to a fault with the Clifford alarm controller putting a permanent 12 v supply on the lock circuit therefore stopping it from locking. Once the supply was cut all fixed, and as an additional bonus the Sunroof also now works. As this is linked into the central locking system too and was being held shut for the same reason.

1xshaunx1 27 Posted April 5, 2018 Well done matey. Can be a complete arse tracing electrical problems. Take it the alarm wasn’t working as it should either. Have you now removed it. Quote Share this post Link to post Share on other sites
