Hi allI have a 2004 Mk6 transit Motorhome with a Sigma S30 alarm system. I initially had a problem when unlocking the indicators did not flash, cured by replacing both fuses.

Now I have intermittent central locking, the alarm switches off, indicators flash but the doors stay locked. I then climb inside and operate one door lever and hey presto were all back to normal for numerous operations. Then it happens again......the doors don’t unlock. Martin

 

Hi
Thinking that it might be a dry joint on the central locking wires all connections are by passenger footwell behind glove box is the central locking module
Check connections there its negative driven

Thank you Ian, I shall be in there in the morning. It’s annoying as it’s intermittent. 👍🏼

 

Hi Ian, thank you for the reply, just been out for a look........pigs orphan of a thing to get at !. God knows how I’ll find a dry joint as I can hardly see the loom except using one eye !. But I shall persevere, nothing else to do !.

thank you again
Martin
