    Currently stuck in France after 4 days now with our motorhome in a Gararge 20 kilometres away after a breakdown on our first campsite.
    Communication is proving difficult with my school French just not able to come anywhere near understanding what the Garage is saying. Fortunately a Tugger ( Ill never knock them again :) ) who speaks fluent French spoke with them yesterday and they believe that the sigma vehicle alarm / immobiliser has damaged the engine ECU and now the engine turns over but won't fire.
    Four days in and I'm getting concerned that they don't really know what to do, the Mechanic said he has a friend who will be coming to see if he can repair it! I guess / hope he's an autoelectrician and not the local Farmer!
    If not it will require a new ECU cost around 900 euros plus labour ouch :(
    Just wondered if anyone has encountered this and would welcome any advice especially @eddievanbitz
    Thanks, Jez

    We had a similar issue when I overloaded a 12v Cigar Lighter socket and it turned out it had blown one of the fuses under the bonnet. That was on a Peugeot Van. But I am guessing the garage will have checked fuses. Unfortunately I cant remember which fuse it was though.

    To me that shouts "immobiliser". I think the normal method is to break the feed to the fuel pump. Have they said they know the fuel pump is running ?

    If Sigma is the problem remove that before starting on ECU.

    I would suggest that you contact the installation company and establish what they did, get the notes emailed to the garage and ask them to "reverse" what the installer did.

    So long as it is correctly installed I cannot think of a situation that the system could damage a modern ECU

    Good luck with this. It may be worth using a "translate" app on your smartphone if you have one.. or using a translate website on your laptop. You cold paste a couple of the replies above into it and have a slow but successful conversation with the garage.

    Sorry not been near WiFi. Okay we are back and running now however the ECU has been replaced ( I think - see following post ) and the alarm / immobiliser removed. This has cost 750 euros. Quite what has gone wrong is still a mystery ( language barrier!) The Van is 2001 2.8jtd ducato.
    Anyway back with the Van which quite honestly looked like it had been vandalized inside day before and will put it behind us.

    Thanks Hilldweller, that would make sense regards the symptoms. Hope they haven't rectified the fault by just removing the sigma and charging me for an ECU that wasn't needed! I should have insisted on seeing the removed item, they did charge me 5 euros for disposal of it ( an eco payment I guess ) but who knows? We are only on the other side of the Channel but it felt like we were in Timbuctoo at times.
