The part where you switch off, re-start and everything is normal until the next hiccup is typical brake light switch.

Symptoms in my case:
"Special programs not available" message - suspension light flags on the dash
"Transmission fault. HDC not available"
Engine will not accelerate beyond 30mph
Switch off and on, everything goes back to normal.

Happens every 1-2 years.

That's a definite update I need to do then. Switch ordered  Robin

Forgot to mention, do not press brake pedal when changing the switch as may well damage the new switch.

If you change the brake pedal switch, be careful. There is a procedure involved - do a search as there are some good write ups on here. It's an easy enough job but there's something you mustn't do before it's fitted. Can't remember what but a search will show it.

Thanks for all the thoughts and suggestions guys. Lets pick up a few of those so that others reading this later may find it useful.
[list]Battery - is about a year old but I'm not ruling it out. I do have a CTEK which I use occasionally if it goes flat (which it has done at least once) including the rejuvenation programme

If it's been flat a couple of times, properly flat, then it might have a weak cell. That will cause problems. I had a battery that lost a cell, my CTEK would run and say "it's charged", put a meter on it and it's 12.7V. Put a load on it and it dropped to <11V.

Yeah. Like don't be tempted to depress or pull the plunger. Just put the switch into the holder, twist and re-install the connector.....and that's it IIRC.

Also Ford, Mazda & LR all use the same switch. For some reason, I find the Mazda lasts a longer on the average.

Goodness knows which one I've gone for - I've just taken a chance on the cheapest Robin

I'v just taken the RRS up the road as an initial test - it behaved impeccably!!!

Later on this afternoon I'll take it to my indie. On the phone he asked if I had tried turning off and restarting when the engine fault appeared. I didn't because I was worried it might not start again. But he thought it could be a sticking EGR Valve that caused the initial fault???? But that wouldn't have caused the transmission or suspension faults would it?

Anyway, we'll hopefully see what his code reader says later on. Robin

OK. Back from the indie. Guess what? Engine fault caused by .....



....split in intercooler hose. Both hoses had just got old and hard and one had given up the ghost. There was a 2 inch split underneath. How the mechanic yesterday didn't see it especially as he actually went round checking the hoses. He must have gone away wondering how he managed to get his gloves so dirty

So - car is back and running well again - actually feels a bit nippier - and the strange groaning noise has gone! This may not have cured all the problems but I'll fit the new brake light switch when it arrives. Fingers crossed!

Thanks to all who made suggestions and tips.  Robin
