I should be grateful if anyone can shed light on the cause and possible cure to the above fault.
My 306 is a late model which has experienced this fault, intermittently, about five times over 2 1/2 years. The problem has been referred to two main agents, who were both familiar with the fault but without, apparently, being able to effect a cure. Peugeot, too, must be familiar with this fault through a BBC Watchdog programme, December 2004, regarding the same fault on 206's.
The trouble is that without knowing all possible causes, and I think there may be a number of them, and effecting a cure for /all/ of them you just have no idea when it might happen again.
Quite simply the engine cuts out completely with complete loss of the electrics, with no warning. As this has, so far, only occurred at one geographical location I feel that this must be RF pick up due to inadequate electrical screening. At this location there is one smallish electricity substation and several domestic satellite aerials which might be the culprit.
The accelerator wiring and the accelerator potentiometer has already been replaced because of inadequate screening.
Oh, the ECU has been replaced as well, but this was related to performance anomalies, especially during cold running.
I am told that on the 206 inadequate earthing of the engine can cause this fault and on the 306 too. But, as I believe RF pick up is at fault here, causing initialisation of the immobiliser, this may be a red herring. I have had problems with RF pick up on the transponder/immobiliser near a local hospital (lots of aerials, etc). I also think that the ECU has something to do with immobilisation.
Some of the above may be plain rubbish but I should nonetheless like to know how to cure the problem and would be glad to receive any advice.
Above all else, how on earth do you fault find for this type of event?
As I use the vehicle for transporting my severely disabled wife I am sure that you will understand my dismay and alarm at this fault.
