Yes
As some of you may have seen on Facebook yesterday, I broke down :(
I'd just done a 40 mile trip on the motorway in the pouring rain, pulled into Asda, stuck a tenner's worth of fuel in, parked at McD's with the engine running for 15 minutes, then pulled onto the motorway.
Within 2 minutes, car cut out with the generic "AntiPollution Fault". I coasted to the hard shoulder. Wouldn't fire up again so I got recovery to bring me home.

Anyway, I've had a bit of a google, and I've hooked up my diagnostics to it. BTW It *doesn't* have a DPF (It was removed before I got the car), so it's nothing to do with that or the EOLYS fluid.

Here are the faults listed under the Engine ECU (No other ECU has relevant faults).

Permanent Fault. Turbo Pressure. Short-circuit to earth or circuit open.
Permanent Fault. EGR control electrovalve fault. Open circuit.
Permanent Fault. Fault. Pre/post heating relay circuit. Relay opened.
Permanent fault. 3rd piston deactivation. Short-circuit to earth or circuit open.
Permanent fault. EGR butterfly position fault. Open circuit.
Permanent fault. Air intake heating circuit. Short-circuit to earth or circuit open.
Permanent fault. Coolant solenoid valve. Open circuit or short circuit to earth.


Now the reason I mention the rain is because while googling, I saw someone mention water ingress through the air intake causing a similar problem.
Also, I remember driving over a bit of motorway where the top layer had been eroded. Like a 3 foot long pothole that's only a couple of cm high.

I wonder if some wiring somewhere has just worked loose?
I had the aircon refilled last week, maybe he knocked something (Although it's been fine all week).

It just won't start now, it turns, fires but dies straight away. Yes, I double checked my receipt, I definitely put diesel in.

Any thoughts from those in the know?
 
Before you do anything else, check the fuel in the tank as well as the receipt.

Thats the obvious first thing that jumps out from your story.
 
You're right Jonathan, that's the first thing I thought of. I wonder if it was petrol in the wrong pump.
I phoned Asda and asked if anyone else had complained of problems with the fuel pumps and there was nothing.
Anyway...heres the strange thing.

I had a wiggle of a few things under the bonnet, unplugged and replugged in the MAF sensor (don't know why I had issues with it a while ago, force of habit), took a few fuses out regarding the fuel pump etc to check them, all fine.
Was going to try a BSI reset, and just thought I'd try to start the car first...it started.

Engine management light was still on, and the generic Anti Pollution Fault message still on the on dash, but it was running
So I plugged my laptop back in to it, and took it for a drive on the motorway, 3k revs for 10 minutes in 3rd gear. Didn't notice any DPF regen (As I suspected, was just incase it hadn't been mapped out/removed properly).

Got home, cleared the fault codes, everything seems fine now...

This is strange. I'm wondering it was water in there somewhere (It was particularly incredibly wet out yesterday and we were driving in it for a couple of hours roughly)
 
Just a thought, but seeing as how it's showing up all these electrical faults is it possible that you've got a loose connector somewhere. Or seeing as how it packed up in pouring rain it could be one that's got full of water and shorting out? First thing I'd check tbh.
 
peugeotcentral forums would be a better place than Tp i would have thought, plenty of pug specialists on there who will be able to offer you more information on your read out
Thats no disrespect to anyone here BTW but i would want advise from those with possible more experience, a bigger pool of knowledge as such, in the same way i would come here on how to repair my camera rather than there lol
 
I've posted pretty much the same over there already ;)
I post on here too cos you're all my friends :D
 
Long shot, but have you checked your earths - I had a car a few years ago that had electrical issues when it was very wet, wipers would slow down when you went through a puddle was one that frustrated me for a while.
I disconnected the earths from the battery, scrubbed and greased them up, tightened up and covered with a layer of grease, did the same to the engine block strap and the body ones.
Don't know which one it was, put didn't have any problems afterwards. As I say, long shot, but could be worth a try to at least eliminate ?
 
Its French. That's your problem ;)

Is there a common earth for all those items? I'd also check earth to ecu and check ecu isn't damp....

Under bonnet, windscreen and door drains/ seals are obvious places to look for odd leaks.
 
A good squirt of a well known Water Dispersant (the 40th formulation the Rocket Fuel company tried IIRC... ;)) over the visible connectors might help prevent a recurrence of the problem. Give them (the connectors) a wiggle while you're under the bonnet since that can help restore dodgy contacts.
 
Do you usually use Supermarket diesel, or do you normally use the likes of Shell. BP, Esso etc? Reason I ask is most supermarkets sell a higher percentage of biodiesel, where as a lot of the big fuel companies have stuck to the older, lower percentage. Whilst your ecu should be able to adjust to it, it may have decided it didn't like it. Also a good possibility the diesel you bought had a high percentage of water in it too. If you can't find any other sources for the problem, I'd avoid the cheap supermarket fuel and run it on decent stuff.
 
I've been filling on Esso for the past 3 or four tankfuls. Couldn't get there the other day, so had to stick a tenner in from Asda.

If it was a tenner in an almost empty tank, it could have been enough to do it.
 
I know it's while ago but I'm stuck with the exact same proplem..did you ever find out what was the problem? I'm thinking of draining the petrol out and try yo start the car ( it did start after taking few fuses out to check but now it's not)
All I can hear is clicking and engine light is on
 
don't know if its possible on the pug ,but on the mondeo diesels (mine included) better performance ,power,less fuel consumption is simply done by blocking off the EGR valve with a blanking plate .it simply means your engine light stays on ,thats not a m.o.t failure so so if you can live with it get rid of the EGR
 
The car wont start at all.. After a full tank from TOP.. this light only came on after that
 
Any ideas? The garage still can't fix it

If yours is the same as Marcels and is an HDI, putting petrol in it might be the problem.
 
It's probably the problem.. But the grage said it's not.. They still can't figure it out..
 
I did find out. It turns out the fuse box was wet I think.
When it was in previously they'd not attached the wheel arch properly (This is my theory), which two days later got ripped off on the motorway, so I drove without it for a while before I fitted a new one.
It wasn't long after that this breakdown happened.

I remember the garage telling me he had to call out the auto electrician who traced it back to water in the electrics around the fuse box, and I surmised this was why.
 
Try the water trap on your diesel filter also if 1.6hdi check the rubber seal near turbo and at crankcase breather they perish and can suck junk in or let turbo get more air than needed

Glad you are running again

Old days yes, good? Hmmm even at the back of a recovery truck you'd get there quicker and in more comfort :p
