147 Door Locks Problem - Will not lock!
First post, hoping to get some help.
Very strange problem that occured last week. Got home from a 40 minute drive - tried to lock the car and nothing but a click from the doors. This was using alarm fob (Toad Ai606 that is linked to the central locking), so I tried to lock using the key. Turned the key, both doors locked, only to then instantly unlock themselves again.
Then tried to lock using the Alfa fob - again just a clicking noise from the doors, but got the Alfa alarm beep - followed by another single beep afterwards (I believe this extra beep indicates a problem?).
The toad works independatly from the Alfa alarm, so set properly and activated when I opened the unlocked doors, I am pretty sure the problem is not to do with the Toad (its been on for almost three years without problem) - My initial thoughts were the solenoids...but what are the chances of them both going at the same time, plus the fact the key locks the door and they then unlock themselves would indicate its something else.
Its been into a local auto electrician who could not diagnose the problem, so I am having to take it to Alfa, who are going to charge £85 + VAT p/h labour, so I want to go armed with some ideas for them to look at first.
Thanks in advance.
