Euro4 D5 / 2.4D DPF or Sensor Issue ?

[graemedench]

OK

Having alot of trouble with my DPF however I'm really starting to think its really the sensor! Any pointers would be great I know Clan has previously said :-
The reading from the sensor with just the ignition on and engine off . ( should be zero)
The reading at idle (3 to 20 hpa depending how much soot in filter )
The reading when revved hard . ( may go up to 70 Hpa with soot in .)


I am seeing off 0Hpa
20 idle when cold quickly going beyond 100
then when revving hard and temperature 500+

I just don't believe it , I bought a new cheap sensor (big mistake) to check against however it gives fault ECM-2A00 Pressure Sensor Trap. Signal too High and will not read any variation in pressure.

Anybody got a feeling on it or seen similar issues ?

with the original sensor I get the following errors saying filter full, signal faulty. signal low. (I know I was an idiot and forgot to take a snapshot of the errors)

Would a blocked DPF show the kind of figures I'm seeing ? I've started taking the EGR apart to clean it out in the mean time and I kindly have the loan of a Mighty Yaris to get to work. I know I can get a Volvo sensor for £100 or I can take the dpf off and flush for £50,

I've never had a DPF problem in the 4 Years I've had this and my driving's not changed at all, Interestingly the sensor that's on the car looks like it may have been replaced at some point as it has numbers etched into it as if maybe a scrappy has put there identifier on it ?

If anyone has maybe values they've seen on a blocked dpf then it would give me a clue,

Sorry to those who have seen this posted (with slightly less info) on the Phase2 section, but maybe others have seen this problem.

I'm looking to sort this and then probably sell up cars been great apart from this really, Feeling the call for a Defender again
