Weird locking issue? PSE?
Hi all, we have had a strange issue for quite some time. I did my research and initially thought the PSE unit must be wet/damp.
Basically the car will lock on the button no problem. But only very rarely will it unlock. There's no activity from the pump at all when you press the unlock button and nothing happens. It never ever fails to lock. It's purely the unlocking which is at fault.
It might not be related, but I'll mention it just in case, but the air bag light came on a while ago and this was said to be a faulty control unit by a specialist. I doubt it has anything to do with the locking issue but as I say, you never know if you don't say anything.
So I took the PSE out of the boot, took the bottom off, left it in a baking hot conservatory for over 48hrs and put it back together, wrapped in a plastic bag to keep it dry.
Absolutely no change. I'm gutted.
I have noticed that the hydraulic fluid is almost right on the minimum line. Could this have anything to do with it? I am picking up some of the correct type of fluid later today. Should I top up or syphon out and refill?
Many thanks for any help/suggestions.
