My car has passed the MOT emissions and has been spot on ever since :-)

Thanks for the indepth info. Much appreciated :-)

Excellent !!

Okee dokee I'll keep everything in mind. Cheers for the info :-)

I've been using this garage for years and trust them. if it fails the MOT through emissions then they'd be liable to fix it and I'm sure would honour that

As far as I can tell when the 4 bolts are undone, to split the casing there is filter in either side. I believe they drilled both sides 5 times. How far through I do not know

Looks like it's given enough flow through to fool the sensor into thinking it's unblocked?

Right all. I took it to my garage and explained. They had it for the day. They removed the filter and drilled 5 large holes in it then refitted. I picked it up but the fault was still there. Antipollution and clean diesel filter ! BUT, 2 days later both faults cleared themselves. This was 2 weeks ago and I couldn't be happier. It cost me £40 that's all so very relieved :-D Thanks for all the help people well chuffed !!

Excellent thanks for that. It does look quite simple, but I think I'll let my garage have a go. Can't be more than an hour's work I suppose. Thanks again :-)

Just for the fun of it then. Has anyone got any idea which wire(s) coming out of the bottom of the ECU inhibit the turbo in limp mode please? I would dearly love to give it a good rollicking in high speed low gear for half an hour just to see if that actually clears the soot, plus would save a fortune and I would smile when I drive again :-/

Ah. Good answer lol. I'll look into it some more then. Thanks again, I'll get back soon as I sort something :-)

Cheers for that. I asked my local garage about the filter and or sensor and they said it was a pig of a job...It doesn't look like a particularly hard job, or am I missing something?! Thanks again :-)

Hiya again. I tried the high speed low gear thing with no joy. Maybe because it won't let me use the turbo there's not enough pressure to clear the soot ? Anyway does anyone know where the DP filter actually is please? And how hard it would be to physically clean it out myself? Thanks :-)

103,000 miles. The engine purrs like a kitten, and when the faults went away for that short time it was a flying machine aswell. Oh that 1 whole week :-D

Thanks for the reply Paul matey. It's Saturday tomorrow so I'll drive from Cardiff to Chepstow n back in 3rd at slightly over 3000 RPM which is all my lovely but twit of a car will let me do grrrrr. I've had a few now so will digest the rest of your kind post tomorrow (or maybe not because the 3rd gear thing at maybe 55 mph will work !!) Get back tomorrow anyway Thanks again :-)

Hello. I bought a 2004 C8 2.0 HDI SX with these faults as the owner said he'd taken it to a garage and they put it on a diagnostic, to be told that it is a faulty diesel filter sensor. I knocked him down £100 because of this. The faults put it into limp mode, no turbo at all :-( After getting it home I Googled the faults and there's a few different thing that could cause them. The sensor being around £50 plus fitting, or the filter itself (many hundreds of quid), or the eolyn? liquid needs changing (again many hundreds of quid) etc etc. After I had the it for 2 weeks both faults reset themselves and I had a perfect running car ! But a week later the faults came back. Since then in the last 2 weeks the faults cleared themselves once more but only for about 5 mins then came back. Anyone knowledgeable enough to give an educated opinion about the probable cause of the faults please as I'm dubious about the original seller's diagnostics. Any decent help appreciated as my car does rubbish milage without the turbo :-/ Thanks
