Any joy with getting it going yet? One question, when it originally went off did you notice that in the centre dial where the running options can be changed from EV to four-wheel drive etc, was the light indicator still on the dial or not?
Well actually my situation is a bit more complex so to speak.
So initially i was "washing" the AC condenser with foam . I was pumping the foam through the vents. Everything was going well till almost the end of the procedure when the sos light went on and car was trying to call the rescue services. It was going on for some 15 minutes till it stopped trying. I got scared of course but in the end the car was functioning normally after that incident. For about 3 weeks. Thenas I was driving out of a residential area and once i hit the road i have accelerated from 10-15 to 45-50kmh to get ahead of the other cars. The red ENGINE FAULT message popped on the dash and the steering got stiff. I have barely managed to get it to the rightmost of the road, it let me drive about 50-70 meters till it stopped completely.
As it happend for the first time (spoiler it happend in several months again after that) i thought i will just "take off the plugs" on the 12v battery for some 30 seconds, the error will clear and i will try to start it. It did not work of course so i have called for the tow and got it to my regular service mechanic guys that i used to service my other cars before.
They read the errors with Autel, there were at least a dozen but they told me the problem is with BSI, they opened it and it looked like it burnt. So they told me i needed to find another BSI and bring it to them for replacement. I did find one from another donor rxh. They swapped it in and miracle have happened. The car would start and run. Yes there were still some errors left but i did not care at the time as i was thinking to take care of them a little later.
Fast forward 3 months and about a 1000 km after, same situation happens. I have accelerated from 10-15 to 50 kmh and the car shuts down. Exactly same situation. I'm towing the car to the same guys. After a couple days they tell me it's highly likely the traction battery is dead. And they can't go past it with their diagnistics. I have taken the battery to other guys who have tested each cell and overall the battery was at 55 percent. I know it's not a good sign but i thought that it's strange that the car won't start at all so i decided to tow the car to Peugeot's official dealer. They tried their magic to make it start but it did not work out. Next day they called me telling that the traction battery is too weak and i should buy a new one or bring them a healthier one. I took the battery to another shop that got it up to 80% capacity. So i brought the battery back to the dealer and now miraculously they were able to go past the battery in their diagnostics investigation and now they tell me the problem is highly likely with the alternator and that i gotta bring them a new one so they could try it and see if it's really the case. Since it's an old model they don't have those alternators in stock.
I thought it's not a cheap gamble to take on. Based on the previous example with the battery that eventually was not the cause of the problem as it appeared, i was not sure i want to spend some Eur2000 just to cut away a possibility.
They also told me that if it's not the alternator then maybe it's the invertor or the wiring in between. Go figure
At that point they told me that they cannot help me with anything unless i bring them a 100% confirmed functional alternator to move forward. So i had to find someone else willing to jump on the task.
So final chapter, i know it's already a novel but stay with me for final couple phrases. The guy that the car is with now, for last 2-3 months already, has managed to start it but it runs 1-2 seconds and stops. He told me that he did not believe that
BSI BSM was burnt the first time. He checked it and saw no damage except from the opening on the plastic cover by the guys at the first shop. He cleaned everything and swapped it back in. It worked, so apparently it wasn't burnt. Now interesting thing is that more than half of erros have gone. The car sees the old
BSI BSM and it's fine.
So to sum it up, I had 2 instances in same conditions, but after the first one the car was made to start again and drive ok-ish (although not for too long)
So at this point i'm taking thematter in my own hands, roaming the forums and looking for solutions as mechanics would not spend more time trying to bring it to life.
