Welcome, you have the same philosophy as me!

Windscreen scuttle would be my first port of call, followed by ensuring the wheel arch liners are in good condition with better fixing plugs.

For the rest, scroll through the 207 section and read the thread titles, that should give you an idea.

 

Hi thanks for the reply

By windscreen scuttle I take it you mean drainage under the bonnet and the wheel arch liners correctly attached to protect from splashing.

Yes I know I could trawl through loads of posts here and probably will but was hoping people would save me time I guess. I thought it would be nice to have all of the electrical issues and potential fixes all in one place to help everyone as it is quite a big problem.

 

ive just bought a 1.4 vti and read about water getting in fuse box from a leaky
water temp censor,on checking mine it was ok,and inside the fuse box everything looked good.still cant see how a leak from there would get to the fuse box.im more concerned about my chain stretching,so i will be changing the oil twice a year and learning all about vvt just incase i have to change the chain.but with only 28k on the clock and she only use,s it for shopping i doubt it.touch wood.

Just to clarify the water ingress issue because I had this happen on my 207 and it was explained in detail by the master technician at Peugeot. The engine coolant if it leaks through a faulty sensor goes through the inside of the wire between the copper strands. Imagine each wire is like a tiny thin pipe with copper strands inside. I didn't believe it was possible so I got a piece of wire from the old wiring loom and tried it using a syringe with water. Sure enough water can slowly flow through inside the insulation between the copper strands. The same thing can happen if the windscreen washer pump leaks (as it did on my 207). The water travels slowly under pressure through the inside of the wire until it comes out inside the connector at the other end. The washer pump wires go straight to the fuse box and the engine coolant sensor wires go to the ECU.

 

Wow that's pretty bizarre will have to look out for it.

 

I cut the insulation back and solder the wires a bit after the plug then shrink wrap it this stops the water Going down as the solder acts as a dam its not a cure for the problem but it will stop the water causing more serious damage later.

 

Thanks for the input yes I think soldering the wire cores together is a good step I wonder if water could use the shrink wrap as a conduit though ?

 

Hi Continental. PM sent as requested.

i was thinking if you just put solder round the outside of the wire whats to stop the water going through the inside.i think i would rather cut the wire and put spade connectors on with electrical grease in the connectors.

Now that's a good idea because I'm sure the male and female crimp connectors such as I've got here have insulating sleeves that should let out any water, will check tomorrow.
Being old school I'd still solder the connectors though.

 

Give the coconut to marrygold, see attached photos of spade connectors.

You can see a that the insulation of the assembled connectors is good while leaving an opening for water to exit.
Would be best to mount with the opening facing down I guess, I think this is probably the way to go.

 

On my washer pump I cut the wires six inches back from the pump and soldered (tinned) the ends. I've then put those tinned ends into blade crimp connectors. I put a smear of grease on the male crimps before plugging them into the female ends.

 

Hi Matt, do you get to the pump wires by removing the wheel arch liner?

 

No, I didn't do it that way actually. I went under the corner of the car (parked on raised kerb) and unplugged the connector from the pump. I then pulled the wire up into the engine bay behind the headlight and worked on it there where there was plenty of room to use the crimp tool. Once finished I dropped the wire back down to where the pump is then went under the car to plug it back in.

 

Sounds like an easy one then, cheers
