Peugeot 5008 - Car starting problems - electrical fault - Sue Wallis

I have a 2012 Peugeot 5008 that has an intermittent electirical fault and wondered if anyone else has had a similar problem.

Every so often, with no rhyme or reason, I get a warning light when I go to start the car that says 'Braking System faulty' and then lots of electirical warning lights come on.

Absolutely nothing happens with the engine when I try to start the car.

But, if I leave it for a few hours, it then starts ok although the battery light stays on and then it goes off after a while.

It then runs perfectly until the next time it happens.

I have taken it to the Peugeot dealer and they have run the diagnostics but couldn't find anything wrong - they say they need to replicate the fault to find out the problem but as it is intermittent this is almost impossible.

I had a new battery fitted when it first happened about a year ago and then it's not happend for another year until recently when it's been happening relatiely frequently.

I wondered if anyone has any similar experience?

Thanks

Sue

Modern cars with complex electronics can be very difficult to fault find with intermittent problems. I would start by checking the battery,even though it’s fairly new,and all the local wiring attached to it,including the chassis and especially engine earth points. Recently looked at a C4 Picasso with similar issues,I grabbed hold of the engine earth lead and it broke away from the engine mount point.

Check the battery voltage when cranking the starter, if it drops to low it will upset the electronics. The wipers often wouldn't work on my C5, a new battery cured the problem. Could also be caused by a high resistance connection in the battery circuit.

Check the voltage across the battery with the engine running, should about 14.4 volts, much less and you could have an alternator problem.
