Clive, not quite the same but had a similar fault with our Purgeot, the engine fan would come on even though the temp gauge was showing normal. This gradually worsened until the fans came on as soon as I started the engine, even when cold( this was while on holiday in SW France). anyway it got to the point of the ECU shutting down to crawler mode,20mph max and no power! Finally got the problem sorted at a main agent in France(although it took them 18 days to sort it!!) it was a fault in the ECU. While relating this story to a RAC mechanic friend, he suggested this kind of problem can often be rectified by disconnecting the battery, connecting a lamp or bulb across the "LEADS", to discharge any residue current and then reconnect the battery. This evidently resets the ECU, rather like Ctrl,Alt,Del on a computer. Any way I had a problem with our current FIAT based MH, erratic fuel gauge, carried out the above "fix" and that seemed to cure the problem. Hope this might be of some help to you.
