Hi I have a 1997 5 door GTI central locking is playing up, unlocks with key pump unit runs on but wont lock with key have to push dont the door pins on all doors and lock drivers door with key
Can you advise where to start?
Could most propably have been either a broken vacuum pipe or a leaking servo in either doors,boot or fuel flap.Mostly the vacuum lines get disconnected in the boot area,since they get easily disturbed by something heavy.Let the pump operate and listen for a leak ... The best way is to work with a small vacuum hand pump with gauge and to isolate in stages and test each door,boot and line for leaks...

unlock with key and hold key over for 30 secs(windows may go down)then lock with key and hold over for 30 secs(windows may go up)then press remote unlock button and hold for 30 secs,you have just reset system...the closer you have to get to the car for the remote to work the lower the battery power.sensor on top of dash(little black dimple)rarely,if at all, goes wrong.....
All these components operate via the central locking control unit. Check fuses No.4, 37, 6, 3, 14. If these fuses are ok, the control unit may be faulty and need to be replaced. The control unit is located behind the right dash panel.[on right hand drive vehicle , may be else where on left hand drive vehicle.
the gas flap is operated with the central locking,stand at rear of car with tailgate open,just inside to the right,under the floormat you will find the central locking pump.but first renew the batteries in the remotes then unlock the car with the key and hold the key over for 30 secs, the windows may go down,
then lock the car with the key and hold over for 30 secs,the windows may go up and the sunroof,if fitted will close,then unlock with remote button held down for 30 secs,this will reset alarm/central locking.
if you need to get to gas flap, pull carpet away in boot behind flap area and pull wire to unlock....
