DPF Faults Everywhere

NeuralCord · Dec 2nd, 2010, 09:42

Hi guys,

After having my S40 for 2 months (Volvo Approved Used), on Sunday night it nicely told me an "Engine System Service" was required.
I dropped it off with Volvo in Leeds, who diagnosed it as a faulty DPF Pressure sensor and that it wasn't covered by my warranty. After contacting Volvo Warranty (who are utterly useless and made me realise the warranty on my car is equally as pathetic) and the service department at Volvo Bradford, I rang Trading Standards about this. I was told that I should go back to the dealer who sold me the car (Volvo Bradford) and that they are liable for selling me a car that is not of satisfactory quality - after-all, a sensor is a completely passive device with no moving parts so any failure is a problem with manufacturing.

After talking with the owner of the dealership (Bradford), and being told that I shouldn't have gone to Trading Standards (the cheek!) I faxed over a copy of the diagnostic report from Leeds Volvo and later heard back that Bradford are willing to contribute 50% of the total cost (est. £614 in total). For something which, after some Googling, seems to be a common fault, I am still pretty shocked by this! Especially considering I've only owned the car for 2 months and it's already had 2 bearings replaced.

I took it to Bradford yesterday for them to diagnose it themselves (why isn't a diagnostic from another Volvo dealer enough? Surely they're all trained Volvo techs?). They put a new sensor on - came up with the fault.
They put my sensor back on - came up with the fault.
Updated the ECM software - claimed it didn't come up with the fault and that they were able to wipe it from memory, but it flagged it the second I got in the car on their forecourt!

I was wondering if anyone else has got Volvo or their dealer to pay for this fault? As far as I've been advised they're completely liable and any mention of their liability comes back with an off-hand comment about how "you really don't need remind me of our obligations".

For the techies out there, the VIDA codes read by Volvo Leeds are:
ECM2454 - Pressure sensor particulate trap sensor signal too low
ECM2002 - Particulate trap faulty signal
ECM2452 - Pressure sensor particulate trap faulty signal

Is it a brand new car, or one you bought used?

NeuralCord · Dec 2nd, 2010, 10:02

Faffi, it's used. Just ticked over 4 years, 56k on it.
Was just under 4 years old when I got it, and 54k.

I do not know your local legal rights, but as to the fault codes, I expect Guru or Clan to be able to give you an explanation as to what the real problem likely is.

Mike, that's a fantastic help, I really appreciate it. I got your PM, but haven't hit the magical 30 posts yet to send you a reply!

where did they get that price ? the sensor is under £100 ... and they do go occasionaly . but the steel pipes going to the DPF should also be changed as they can get restricted inside .
They can read out the pressure from their equipment . the vital reading is 0 pressure when engine off and ignition on have they tried this ? If it is reading some positive pressure then the sensor is faulty .. Another thing the wires can break internaly near the plug on the sensor have they looked at this ?

Clan, that price is for:

- DPF Press. sensor - £70
- BPF burn off (which can be initiated by me, surely?) - ?
- ECM update - £142! For software! I don't pay that much to Microsoft for Windows, which costs millions to develop!
- Pipes - £79
- Diagnostic charge (cheeky!) - £97.52

I asked about the readout from the sensor, only to be fobbed off with "it's within parameters".

Mike,

It's one of the D4204T engines.
