Hi all,
I eventually had to source the seat relay from MB which was around £24. Installed it and all is well.
For anyone thinking about this job it is not too much hassle to actually drop the panel underneath the steering column and replace the relay. It took me around 15-20 minutes without too much cursing
.
If you want to try and actually repair the relay its self then you'd need to source the diodes, have a very good small soldering iron, good eyesight and a steady hand are also required. I gave up on the repair and forked out the £24.
Just a mention of my experience with ACD Lancashire. I've contacted them twice now regarding fairly inexpensive parts for my xfire and twice they've messed me about. I'm sure some have had a good service but it seems to me that their quality of service is determined by how much profit they will make from a particular transaction. I personally won't attempt to use them again.
Enjoy the weather whilst it lasts,
cheers,
Pete.
