i'll have a dig around later, might have a module that'll fit for you
Any luck with that module Chris?
I removed my one yesterday and dismantled it. Sure enough two of the micro switch soldered joints had dry joints at the plug connection end:-

Re-soldered, reassembled and refitted and works perfectly electrically now. However, there is a mechanical problem that I suspect we have has for a long time that has only come to light since the electrical side failed. It will lock/unlock electrically fine (now), it will lock/unlock mechanically (using inside handle) fine, but if you lock electrically it will not unlock mechanically

So it's back together and working but if the electrical side ever fails in the locked position I could be in similar if not worse situation again.
So, if I can get hold of one at a good price then I'll replace it

Right back to the mk1...........oil pressure sensor to replace to get my VDO oil pressure gauge to work
