Hi - just joined the forum and this is my 1st post.
Car 307SW HDi 110bhp 53 plate 55 miles
4 weeks ago I had a 48k mile service at the Peugeot dealership in Linwood, Renfrewshire. I mentioned that there was an ANTIPOLLUTION fault reported and would they have a look at it. Suffice to say they came back and told me they could not find anything, but mentioned that the flywheel and exhaust needed fixing.
Car had been running ok. Within days the car seized and flywheel had gone. I had it recovered to a local Kwik Fit and had repairs done. However on taking the car back it had gone into "limp home" mode under 2500revs. Took it back to the Peugeot dealer and they found the following ECU faults (all permanent):
1. Fuel pressure signal. Signal short circuit to positive, open circuit
2. Differential exhaust pressure signal. Coherence of the differential pressure when stopped
3. Additive system. Fuel tank cap pressure signal
They have suggested performing the following work:
Replace Fuel cap sensor 1503T2 £20.03
Replace pressure sensor FAP 161809 £73.74
Replace Rail pressure sensor 19207R £151.99
Add 2 litres of FAP Fluid 973685 £27.27
add in 3 hours of labour at £65/hr and it comes to £581.65 (inc vat)
I'm also concerned that they may have ignored the Particulate filter which I think should be changed aroun 50k miles
Could this problem could be related to the EGR?
Any advice on how I proceed with this as I've read many forums and I'm concerned that I do not want many visits and the problem still exists - especially after the recent costs to get the car back on the road.

Mutiple sensors do not just simultaneously fail!
From what you have said KF had the gearbox out, with major work having been carried out I would be looking for a common factor. Broken wiring, incorrect reconnection of sensors or something similar.
I would also change your main dealer who is looking to make money by just changing parts without understanding the true nature of the problem.

What did kwik fit do?
(and why did you take a complex diesel to kwik fit in the first place?)

Firstly; thanks for proper car details - so many don't... [And they wait - and they wait....]
It wasn't a good idea to ignore that warning from the dealer. "Within days the car seized and the flywheel had gone."
That's no minor fault on an HDi; what did all that come to - £1000+? What did they replace, a failed DMF often slices the engine and gearbox clean in two.
The fuel cap sensor loom is a common 307 fault - it's very important - do it. [And - while they're resetting the additive ECU - top-up the fluid.]
Next up; the differential pressure sensor on the FAP. What did Kwik-fit do to it? What was the source of your reference to "exhaust needed fixing?"
The rail pressure sensor is very near the starter - that needs removing to access the flywheel - did they break it or just leave it disconnected.
I'm sure that the dealers will be happy to fit you a new FAP now that one is due - but whether you will be happy when you see the bill.....

They initially told me "the flywheel was squeaking" - had they said this was about to fail I'd have done something straight away. I had no idea that this was likely to happen. Hindsight is a wonderful thing eh? I only used Peugeot to service the car because of the Antipollution warning light. The fact that they were unable to locate any problems with the diagnostics led me to go elsewhere
Car is due for an MOT in December and one of the parts Peugeot suggested replacing prior to this was the exhaust and new wipers.
My local KF have been fairly reliable and I thought I'd go for a 2nd opinion on the flywheel - however the problem kicked in within hours. Too late by then. Ouch.
All in the work (including exhaust, labour, etc) performed by KF was £1300 which to be fair was very close to the price I'd been quoted by Peugeot for the after service work.
I'm not sure whether KF did any damage to the differential pressure sensor on the FAP or whether that was already a problem pre Peugeot service, that they failed to pick up on the diags.
I also picked up on a EGR valve problem at www.peugeotcentral.co.uk/modules.php?name=Forums&f...3
which is why I thought there might be something related to the KF exhaust replacement.
I've got a feeling that Rail pressure sensor may be disconnected - I've seen some lines hanging down in the engine bay, but I'm not entirely sure whether these may be connected. Is there a picure on the web of what I should look for? Alternatively is there a way I can upload an photo or send via email? Let me know.
As for the actual FAP - I've read so many topics in the last 24 hours about the service intervals for a new replacement, using re-conditioned/re-gen parts, etc - I really don't know what to do for the best.
My plan is to get them to carry out the following:
1. Replace fuel cap sensor & fluid
2. Replace pressure sensor on FAP
What about ECU? I'd imagine there must be some process for resetting this and perhaps updating the ECU with a latest release.
I know I need to get more work done - my concern is that I get everything doen I still end up with more problems.
BTW I really appreciate all the helpful advice. I wish I'd done a bit more research 2 weeks ago.

BTW how much would a new FAP be versus a reconditioned one.

So many points to cover here; I'll just have to use a lot of quote to do it. [Sorry PU]
I only used Peugeot to service the car because of the Antipollution warning light. The fact that they were unable to locate any problems with the diagnostics led me to go elsewhere
That's the first odd thing. The self-diagnosis is brilliant on these; if the AP warning was up there would have been codes; which - presumably - they cleared?
My local KF have been fairly reliable and I thought I'd go for a 2nd opinion on the flywheel - however the problem kicked in within hours. Too late by then. Ouch.
I'd never let K-F touch anything; be very careful taking a car of this horrendous complexity anywhere near them. Did they fit a genuine clutch and flywheel? What about the damage to the bellhousing etc?
I'm not sure whether KF did any damage to the differential pressure sensor on the FAP or whether that was already a problem pre Peugeot service that they failed to pick up on the diags.
Which bit of the exhaust did they fit? They would have had to disconnect the FAP sensor to do the flywheel etc. Frankly; most of your subsequent problems appear to be down to their goons. [You were lucky that they didn't "discover" that your shocks, or discs, were... "dangerous!"]
I also picked up on a EGR valve problem at www.peugeotcentral.co.uk/modules.php?name=Forums&f...3 which is why I thought there might be something related to the KF exhaust replacement.
I see nothing to suggest an EGR issue at all.
I've got a feeling that Rail pressure sensor may be disconnected - I've seen some lines hanging down in the engine bay but I'm not entirely sure whether these may be connected.
The rail pressure sensor is a big brass nut under the fuel rail at the g/box end. [If this is a 2.0 HDi.] It's plug is three wire; flat one end, rounded the other.
My plan is to get them to carry out the following: 1. Replace fuel cap sensor & fluid 2. Replace pressure sensor on FAP
Good move. But get them to check K-F's work first. It wasn't in limp before it went there.
What about ECU? I'd imagine there must be some process for resetting this and perhaps updating the ECU with a latest release.
The additive ECU is a separate one. It will need re-setting to adapt to the new flap sensor and the new additive quantity. There is no level sensor - it measures the amount injected.
