Just a bigto Brian H for posting how to retro fit cruise control to a M54 engine. I followed his instructions and the job was done in 15 mins. The hardest part was removing the lower steering column trim panel. Brian, when (if) we meet up I'll buy you a beer, Thanks Dave
Got the interface Friday and had the switch for a while so ready to fit, I've checked all the connectors are there. Thanks to Sopers for getting the part only 1 left now I think.
Cruise control fitted tonight and all works. I got a replacement bottom half of the steering column shroud just in case I ever take it off and I can put the original back on. Blagged it for £2 from a local scrappy from an E36.
