Peugeot Boxer Error Code p2100 and constantly stalling engine. (1 Viewer)

[CamperJack]

A few weeks before Christmas (when travel was allowed) I took the van away to Yorkshire, however it developed a fault. The engine stalls and cuts out when you slow down / the revs drop. Also it drives rather juddery / shaky. When the engine cuts this means the power steering is lost and the breaks go a wee bit iffy. Obviously this is far from safe and so my trip was cut short and the van, disgraced, was carried home C/O Green Flag on the back of a low loader.

My friend had plugged it in with one of those gadgets that reads faults when a error light showed on the dash. It read p2100. On googling it it seems to be (from what I can understand of the technical stuff) an issue with an "accelerator actuator". Whatever one of those is...

My friend cleared the fault code and the light has gone and not come back. However the fault (stalling / juddery driving) persists. Obviously it wants looking at.

I'm not mechanically minded so I wondered if anyone who knows a bit more than me might want to offer a guess at what sort of price I'm looking at for a replacement actuator? Being clueless a garage could say any figure and I'd have literally no idea if it was a fair price or if I was being ripped off!

Hopefully it will not cost a big heap of money!

Give Eurocarparts a ring with your reg number and ask them for a quote for said part.
That is your start price.
Then labour { phone around or maybe DIY}.
Check no obstructions by foot pedals { carpets etc }
Recommend having an interim service at the same time.
Engine oil change
Oil filter change
Fuel filter change
Air filter change.
That's what I would do if it was My van..

Plenty of fitting instructions on YouTube

Throttle position actuator sensor. I had similar fault on traffic and was the clutch pedal sensor. I picked it up with life running data as was doing my head in at the time. I don’t have the van anymore, I used auto doctor app with the paid version, then I cancelled the subscription.

when my citroen relay was cutting out on slowing down it turned out to be the pressure relief valve in the fuel rail, we only found it by watching the live data on a snap on scanner, think ford call it a suction control valve and it was around £50 i have the 2.2 ford puma engine in mine http://rover.ebay.com/rover/1/710-5...0001&campid=5338547443&icep_item=274052625690

P2100 is a generic code, I know the code reader your friend used shows it as the AA but I'd be wary of trusting it unless it was Peugeot diagnostic equipment. Before I spent any money I'd get it into a Peugeot garage and get the code read again, they'll have your pants down for the pleasure but it should point you to the exact fault.

The fault light on the dashboard has now disappeared despite the fact the actual issue is just as bad. Will it show up again if I ask Peugeot to scan it?

 

[Campervan_man]

Main dealers will sort it as they have the specialised test equipment.
Don't give them a blank cheque ask what the cost will be before you proceed.
I asked a Vauxhall Dealership to 'fault diagnose' and I said I would pay if the diagnosis was correct,
it wasn't so I got My money back.
Meriva kept cutting out at a junction { stalling }. I changed the car in the end.

The truth is I don't know, but I think I know where you are coming from. My work van, Transit had a problem with the fuel pump recently, when I got it to the garage the dashboard light had gone off, the diagnostics read, no codes although the problem was still present. Worth a call to a Peugeot garage to ask the question.

Obd2 codes come in different flavours, some manufacturers eg fiat even hijack the generic code and give them slightly different descriptions. See obd2 file in resource area ( compiled from different sources)

Fiat 2 P2100 throttle actuator control (PWM), Overtemperature

The addition of "overtemperature " to the standard code sounds significant.

NOTE

just because a device throws up a code doesn't mean you need to replace it eg sensors out of range could be due to a leaking pipe or dodgy connection.
Live data from multiecuscan (if a fiat engine) could help confirm diagnosis.

Well, my wallet is £580 lighter but the issue is finally resolved.

My mechanic friend who works for the RAC did some diagnostic works for me. About three hours in he found the culprit. A blocked DPF atomizer. He only charged me £60 and, as I was quoted £100 / hour labour for specialist diagnostics, he saved me an absolute fortune. It's a shame he doesn't have his garage anymore.

He booked me into his friends garage who took out the DPF atomizer (a big job so I am told - apparently it was sized in place). They also got an auto-electrician to work his magic. As the fuel wasn't getting into the DPF it was getting into the oil. The level was well over max. So I had them change the oil and filter. The service light came on while they were working on the van, but a full service was done less than 500 miles ago by another garage. I'm very confused about why this would happen after paying top dollar for another garage to do a full service. I can only assume the original garage didn't reset the service timer in the silly computer. This work cost me £515.

The garage that did the work is Car Craft in Northwich. I cannot recommend them enough. Dan there is a great bloke. Sometimes I find mechanics can be a little grumpy or not so sociable. Dan was friendly, chatty, smiley, and didn't mind me asking questions about this and that. I'll definitely be taking the van back there in the future.

It's a great novelty to have an engine that goes!

Glad you didn't change the throttle actuator.
Thanks for sharing the outcome. Is it a ford or fiat engine?

its a boxer but the 2.2L in it is made by ford.

Spoke too soon!!

My sister has recently moved in with me so I went up to Yorkshire to collect her furniture in the van.

50 miles on the motorway it drove like a dream. Couldn't fault it. Got off the motorway and five minutes later and it had a mad ten minutes. Juddering and jolting like a bucking bronco while moving, and on slowing down and the revs dropping it stalled three times. On stopping, if it didn't stall, the revs were far from steady. The counter fluctuating. See video of my van.



Then as suddenly as it started it drove fine again. On arriving at our destination I checked the oil. The reading is too high. As said before the garage changed the oil and filter when it was in last time.

I drove back home (76 miles) and it was absolutely faultless in terms of performance. No hint of anything being wrong, whatsoever.

I spoke to the garage again and they said "its done a DPF regen and may have dumped fuel into the oil". It's going back in tomorrow and they will test the oil for presence of contaminates and correct the level, or replace if contaminated.

I am starting to wonder if something is wrong with the fuel system? Also dubious that simply letting some oil out will cure it.

As ever, I am grateful to anyone who may be able to offer any suggestions or advice about this issue.

I need to get this van right because I should be going semi full time (four days to a couple of weeks at a time) in summer, all being well. It's all starting to get rather stressful.
