V50 Engine 2.0D : - Loss of Turbo - DPF Sensor ?

iferg · Nov 24th, 2012, 13:20

Hi,

For past 2 days the engine won't go above about 2.8k RPM. We changed the DPF fluid last Monday and car was fine until after the heavy rain etc on Thursday. The air filter has been checked and is ok.

Got the codes read and there are 2 showing :

P2454 - DPF Differential Pressure sensor Circuit Low
P2002 - Particle Trap efficiency below threshold Bank 1

I've had a search around and seems that it may be a faulty DPF sensor but wanted advice on whether this is the most likely case or whether something needs to be reset after a DPF fluid change and that might sort the problem.

Any thoughts advice / advice please.

most likely the sensor , but you need to read out the pressure reading from it with Vida . should be zero with ignition on and up to 20 hpa idling ( depending how much soot is in there ) ... and linear increase with more rpm ....
did you reset the level gauge when topping up the EOLYS ?

I didn't realise there was a level gauge to reset, is that also done via Vida ? I know I need to go to a dealership together the "engine system service required" indicator reset.

yes the additive tank gauge needs to be reset or it may think it is out of additive , it needs resetting on vida with a FULL tank ...
