Hi Guys

I know this subjext will have been covered but here goes with some Specifics.

I have a 2007 1.6HDI 407 which has run almost perfect.
put diesel in last night and "Risk of Particle filter blocking" pops up.

I assume it's out of additive at 120k

is there anyone who can re programme the ECU to turn the thing off and disable the DPF as i know from experience that they are a PINA.

I'm in York and any help would be appreciated.

There are two other issues that i need to get fixed, one may be related.

* one glow plug keeps throwing an error (no EML but codes)
* one injector had a leak past the seal, but a nip up and it stopped.

Thanks

Nik

The DPF is getting to the point where it's clogging. You need to take the DPF off and give it a thorough clean through with hot water, preferably a jet washer.

The additive quantity can be checked using planet, it may not need filling.

The car needs frequent runs where the exhaust temp is hot enough to burn the particulates in the filter. Usually this means at least half an hour with revs above 2300 down the motorway.

If you have a glow plug fault, then the filter won't regenerate and become clogged. Similar if the cooling fan isn't working.

Make sure the glow plugs and high speed setting on the fan are working first, and then clean out the DPF and take it for a good blast down the motorway.

Keep on top of the oil filter changes on this engine too.

The additive ECU can be programmed as being absent but it won't stop the warnings appearing. The errors will need to be cleared which will likely need the DPF cleaning out or removing and then the engine ecu will need to be remapped to remove the DPF. If my understanding is correct, a Bosch ecu can be remapped by connecting a programmer to upload the new map but a Siemens needs to be opened up and have either the chip removed and programmed externally or programmed in situ with a piggyback clip.

I have PM'd you

the high speed setting on the fan is working fine and the car gets a good 80mph run daily.
so i need to get it plugged in to check the additive level and run diag on the glow plugs before i start spending on it.
