central locking partially unlocking June 14, 2023, 10:55:15 AM in the jetta, i can her the vacuum pump, but it does turn off lateand the passenger side as well as the trunk remains closed.even by hand i can not open the trunkand, since it is separated by a welded steel plate,i have no idea how to access it now,which would be very funny, if i had perishable goods in there.any suggestions ? :-)

Re: central locking partially unlocking Reply #2 – June 15, 2023, 12:52:03 PM my mistake. i forgot that one can turn the key to the right. then it opens(regarding the hatch, there would have been a bag riveted in there).the central locking issue seems to be somewhat sporadic,cause lately it once worked as always but then the same again.are there known locations,where the vacuum tube tends to break ?

So I would say the potential failure points are either at a joint or at a bend. The c/l for my rear hatch doesn’t work. I presume it’s a break in the pipe where it gets continuously flexed at the hinge, but haven’t investigated.
Re: central locking partially unlocking Reply #4 – July 24, 2023, 02:29:01 AM thank you for the hints.the web gave me a manual for a mk3.it said i should listen, so i did.there is a little bit of a high pitch sound,like from a ultrasonic cleaner, near the vacuum pump.it isn't supposed to be there, true ?the connection looks ok and i'm not that sure about what to do,but i will try something as soon i find some time.if you have a leak in the bend, wouldn't it get worseand prevent some locks from opening correctly at some point ?
