Thanks for this video. The clowns at my local garage told me it was the ecu unit despite me telling them of this video. Took it to another garage who diagnosed the problem as the abs module. A common fault on the 207.

had same thing happen to me, and i was told the same about the water from the washer bottle. water also leaked through fuse box down into computer unit below. Peugeot wanted £3000 to change wiring harness and computer / braking unit and fuse box. A local auto electrician changed fuse box, a new computer unit, and put a new wiring harness plug on end for a lot less. Turns out it's water dripping down from the bulk head, onto cable that enters fuse box, and finding its way in. ( but that would be a manufacturer fault ) Mine is now wrapped in a thick plastic and tie wrapped off. £2 cure.

I simply topped up my brake fluid lol solved the problem

Hi all, I have a Peugeot 207 HDi 1.6 Turbo Diesel, mine seems to have a similar problem to you all, water infiltration into the electric system with heavy rain and high humidity/fogging of windows, the electrical system goes mad. Mine has a sound like the blinkers going on and off but the power steering, power windows, alternator, cruise control, aircon, all stop working normally until the car dries out. I hear something clicking on and off madly inside the glove box (my car is right-hand drive) but I still haven't been able to locate the part. So, in my case it's usually with wet weather, so obviously it seems like water in the electrical system problem. I had thought it might be a loose ground wire somewhere where all these components work as well. Take yours to a good auto electrician and mention the comments here. It's not ABS or individual component problems for the most part from what I have followed up on other forums. For the most part, the car is very reliable. Mine already has 342000 km, does not consume oil, goes well, averages 880kms in city driving on a full tank, 1100 highway, the electricals are the problem, not mechanicals. Rear window regulators, the cables have popped out and need replacing, driver power windows command has broken a support and plastic is starting to get dull, driver door padding starting to scuff. Otherwise no complaints.

Thanks for the video. I need a new fusebox then too. I was shocked at the price £60-ish for a fuse box. F hell.

My P207 has some issue like this but only when he stays out of garage in high temperature - then he gets a lot of errors - after killing them by app Torque the problem dissapers to next time. Do you think its the same issue with some pin-s?

I’ve had the same problem so I have just ordered a new fuse box would this be a simple removal and install without having to reprogram ECU? Thanks

hello the same problem happened to me, wonder if the problem is taking water? or if it's a chronic problem, you can tell me I want to take action.

Mine got no corrosion changed the box but still the lights are still there. What can I do now.

i've got this issue at the moment i'm reluctant to take the connector off incase i snap any more pins, it only came about after changing the front disk brakes oddly enough :/

I've got abs /steering wheel / engine lights on but all of my plug connectors including the brown one have no corrosion. Now i dont know what else could be the cause of all of the lights? Is it any of the individual fuses which need replacing?

I've never liked the Prince engined 207's. The whine they make gets on my nerves
