#1: Wet immobiliser - dry out or replace completely? Author: D-Zaak, Location: Sydney, AustraliaPosted: Wed May 30, 2012 5:51 am ---- Hi All,
UPDATE:
Turns out the issue is the ECU after all. The dealer is pushing the electrician to replace the whole ECU with a brand new one instead of a 2nd hand one. I feel a lot better about this now.
Original post:
I have just bought a 206, however am yet to receive it yet. I bought it based on its great service history and expected there to be no problems, BUT....
When the dealer got it detailed, the stupid car washers sprayed the water under the hood and caused some issues. The car wouldn't start.
The dealer has been great and has got the detailers to pay for an auto-electrician (Peugeot certified as well) to check it out. He said the immobiliser is wet, and will have to dry it out, then reprogram it. I have already asked about replacing it and he kept reassuring me that it just needs to dry. If the Peugeot electrician recommends it as the best fix, then I should listen to him.
My question is, should I push to replace the part? If the immobiliser gets wet, is it bad forever? Will it continue to play up somewhere down the track? (1 month? 6 months? 6 Years?).
They will give me a 30 day guarantee and fix it for free if the issue happens again within that period. I'm just p**sed off that I got a car with a great history, and the car washer might have F'd it up.
Will the immobiliser or electronics ever be the same? If a PPeuguot certified auto-electrician thinks it's fine to dry out, then it should be fine right? I just don't want to go 110k/h down the highway to havethe immobiliser fail and I'm driving with the engine shutting down a long with power steering and other electronics, etc.
Thanks for all your advise guys. Last edited by D-Zaak on Thu May 31, 2012 7:14 am; edited 1 time in total

So as their electritian has said its fine they shouldn't object to extending your warranty period to at least a year on the immobiliser as it wasn't your fault it's been washed!!

That in turn talks to the ECU (Engine Control Unit) which is in the engine-bay.
Maybe the ECU got wet but that shouldn't necessarily knock-it out of action.
Anyway unless water-ingress has been very-very bad into an actual unit (which I can't understand
or imagine happening) drying-out should be fine as long as it then works repeatedly and reliably
The real question is, why did this happen at all?
Obviously you don't want a repeat problem in wet-weather conditions.
Now if they used high-pressure washer under the hood as you say, that is simply stupid and would explain non-starter.

Thanks for the reply. When you say "quickly", how long are we talking here?
Also, in reply to V9977, thanks for the info. It was very helpful.

Bit like I said, tell them you want it covered on warranty for at least a year.

Water from the jets can't get into the ECU and solely destroy the immo, if water got in, it would ruin it all.
Plus the ECU needs to be heated up to break the waterproof seal.
I would be very wary, and ask for a second opinion on the actual fault.

I've been digging around, and it looks like I misunderstood something . They are still in the diagnosis phase and are just saying the immobiliser COULD be the issue. When they have more info, I'll update.
