Regeneration question / Turbo boost issue

[buaan]

Hi all.

2005 407 2.0HDI with DPF

A few questions that I hope you can help me with.

1. How do I know when my car is regenerating?

2. How do I force it to do it? (without plugging in planet)

3. What are the symptoms of a clogged DPF?


Heres my problem. I've been lurking here and 407 owners trying to find a solution but no luck yet.

Intermittently I will loose turbo boost, usually driving up a hill or out of a roundabout under load. The car doesnt get a limp mode rev limit, just loss of boost. If I pull over, switch engine off and restart 30secs later it works again.

Using a code reader I kept getting P1351 for glow plugs. Fitted new ones 2 weekends ago but it still does it.

Does anyone think a clogged DPF could be causing the car to shut the turbo wastegate as it is being over restricted by the DPF?

Any advice is appreciated

1) You hear the fan

2) Drive for 20 mins on motorway in 4th gear, keep revs over 3000. DON'T let them fall below!

3) "Anti-pollution fault" on screen.

Thanks Gibbo. I'll try that out.

Still struggling to get to the bottom of the loss of boost. Might be worth pressure washing the DPF?

I also cleaned the EGR out last weekend.

Does anyone has Planet near the Huddersfield area and is willing to plug my car in? Willing to reimburse you for your time

Ive just has something very similar with mine and with a dose of redex diesel treatment and a new fuel filter it has gone away.

As for regens youll know as your exhaust will sound like its got a hole in it.

Drivers and passenger door mirrors will heat up on its own when regenerating
