98 A8 4.2L - Central Locking Question
 

Situation;
- locks do not work (vacuum leak in the line somewhere - pump runs too long)
- vacuum trunk release works fine but response is a little slow
- Vacuum pump seems to be fully functional (pulled the pump - I don't think it's broken)

Question;

Is there a certain location that these things are prone to leaking (before I tear every door apart)?

Local dealership told me it's a cheap fix, but expensive to find the leak.......

Whats are the faults in the central locking module? If all four doors aren't locking its either the module or a line close to it.

The fault code is;

01367 - Run time exceeded (likely leak)

Check the connections at the vacuum resevoir (big round blue things behind the bumper) and make sure its not leaking from there or the lines going to it. If its not there or by the pump its time to take apart the doors.
