Hi, I'm new to the forum and new to the Peugeot expert.

We have just purchased a 2005 Peugeot expert HDI as a second van for our business. I bought the expert as it's the perfect size in the back for what we need and it has the three seats up front. We have only owned it for a few days and covered around 200 miles of what I'd hoped would be faultless driving.

Yesterday on our way back from our first job we were slowly moving in the morning rush traffic. The van stalled as I had started to move forward and I thought it was just me not being used to it. I attempted to start the van again but it just turned over. Typically it had stalled on a narrow road and going up hill. With the help of a few motorists just wanting to get to work, we managed to push the van to the side of the road. When I was trying to start the van I noticed the temp gauge going up and down. I checked all the fluids and basically just looked for anything obvious. After 10 minutes I managed to start the van up and drive a mile to get it home. I phoned my mechanic and he came round and said it sounds like a battery lead is loose. I popped the bonnet and yes, the negative lead was pretty loose. We tightened it up and I hoped that would solve it.

Late last night travelling to a job the van decided to cut out on me. I looked at the dash and the temperature light was on and the needle was rising quickly. I had and luckily managed to get it off road. Again I popped the bonnet, all levels good, battery connections tight. The temperature needle was fluctuating so I unplugged the plug on top of the expansion tank, no idea what it does but I was trying anything. Tried to start it with it unplugged but just turned over. I plugged it back in and it started and the temperature settled again to just over 70.

I'm totally baffled as to what is causing this issue. Have I just bought a knackered van? Sorry if it long winded but I'm just trying to explain everything. The van showed no signs of being an issue it just suddenly stops running. I would really appreciate any info anyone could give as to what this could be. I can't currently use the van for fear of breaking down and not being able to get to my jobs.

Would maybe suggest first checking where the main earth from the battery bolts onto the gearbox,make sure its clean and not just tight,common problem on many peugeots and citroens :)

The sensor on top of tank is just to tell you if level drops its not the temp sensor

The temp gauge jumping around is just BECAUSE of the non starting issue its not the cause merely a symptom BUT having said that the temp sensor on the engine MAY be faulty and the ecu is shutting down the engine im not entirely sure peugeot ECUs do this but i know some vehicles do cut the engine if they see to high a temp.

Just so we are clear im not saying your engine is overheating im saying the ecu THINKS its overheating.

If changing the temp sensor does not cure it then its likely to be my favourite a bad wiring joint somewhere or rotten wiring.

Thanks for the info :)

My mechanic put diagnostics on it today and one of the issues shown was air flow meter. Not sure if that could cause the issue or if that's another separate issue. After clearing the code, it came back once the van was started up.

This Monday it's going to a diesel specialist to be checked over so hopefully he will find what it is.

Appreciate all the info supplied.

No he didn't have his main diagnostic machine with him and the one he used wouldn't show live data.

Hopefully the mech I see on Monday will get a better idea. I'm hoping it's sensor rather than wiring.

Had the van in to a diesel specialist yesterday. Ran diagnostics with no issues then he spotted a split pipe. The boost pipe was hanging off and there was oil all over the wiring loom.

Pipe replaced and huge noticeable difference with acceleration. Going to run it and see if that cures the stalling issue.

Just to update this thread. After having the pipe replaced that was split, the van cut out again and took around 20 mins to get it started.

Back to the garage and diagnostic shows an error with the crank shaft sensor. That replaced and two wires under the ECU repaired, let's see how it goes.
