The Yellow Engine Light is Back
computer says DPF not so sure this time as it indicates normal and 50% clogged going to try and force a regen on Friday when driving home have to say the removal and software patch for £350 is now sounding very tempting !!
Why not post your pressure values.
It's listed as 'differential pressure sensor' in MultiECUscan, tab F4 'parameters'
What's the pressure at 2000rpm, 2500rpm and 3000rpm ?
50% clogging is not relevant to soot loading, it's a general control variable.
You can drill *some* of the back of the dpf core and I guarantee that the vibrations will loosen a lot of soot from the face. Yoiu might want to try washing it, off the vehicle.
New DPF's on ebay are £235. I've read a fair few posts by people on other car forums who use these third party dpf's successfully, they seem to perform like the original parts. If I wasn't able to do my own work I wouldn't think twice about walking into a tyre/exhaust depot with a new dpf under my arm and ask them to fit it. (phone for a quote first
What you need to remember though is that although the ECU *ought to* be able to 'learn' new parameters for a new dpf, I think it is still a good idea to use the 'replace dpf' routine in MES or AlfaOBD, which requires a registered version of the software.
If you go for a new one, can I have your old one, for experimenting
But maybe you want to keep it ? If I felt I was going to buy a new one anyway I would take it off and wash it...or just try a bit of drilling first, because there's nothing to lose and it could get the EML light off as well as restore performance. I've shown that you won't get an EML light by doing even drastic drilling, and there's every chance you'll improve the situation by trying even partial drilling. I'm not trying to persuade you to drill, if you can afford a remap right now or a new filter good on you
