Hello, I've a 05 407 2.0 diesel saloon. Several weeks ago, after a long run, if I stopped for about 20 minutes and then restarted the car it kept stalling. I tried to keep the revs up using the accelerator pedal but I could feel the engine trying to shut down.If it stalled then I had to leave it for several hours before it would restart. This problem got more frequent and I took it to my Peugeot dealer for a diagnostic. They said it needed a new ECU and EGR valve costing £1800!. The next day the car went through the stalling routine again. After attempts to keep the car going the starter motor stopped turning over, I rang the Peugeot garage and they said that it sounded like my ECU had failed altogether. I managed to tow the car to the local garage I use and made the decision to send the old ECU to a company who return a re-con one which has been programmed using your original. This 'new' one has been fitted but the engine will still not turn over using the key. The mechanic tried the old trick of applying power direct to the starter motor and it turned over and fired up the engine but stalled after about 8 seconds (similar to what was happening before). Is there something that could be preventing the engine turn over on the key, faulty wire / fuse /BCR aside from possibly the ECU still not being right? Are all the issues connected or could the starter problem be a different issue. The mechanic has hit a wall with this so any help would be appreciated, regards Peter.
Although it's taken this long to hear back, I do still require an answer to my query.
