Peugeot 406 2.2 HDi DW12 engine woes...

[chazola]

Hi, my gf's 2.2 Hdi estate died on her this weekend- she said she was just going along normally then noticed a severe lack of power, which finally ended in black smoke coming from the engine bay and the car shutting down.

The EML had been on for a few months with the ever-helpful 'anti pollution fault' displayed on start-up, but the car was driving fine with no issues like limp-home mode or anything, except in the last month the ASR/ESP fault light would come on occasionally. The car lives quite far away from me so I hadn't had a chance to investigate the EML etc faults.

I know when the codes were last read it said DPF additive level low/faulty and I'm wondering if the filter has finally clogged?

I've had it on a ramp and there were no obvious spilt hoses etc, it sounds like a high pressure noise (like the turbo on full chat/and almost like a really badly slipping belt) just at idle, coming from the turbo/cat area. Giving it a little bit of gas and going over 1000rpm 'tuned' & got rid of the noise, and it drove but very juddery like a blocked fuel filter and won't go over 1500rpm.

So far we've tried removing/blanking the EGR, disconnecting the turbo's vacuum line, and unplugging MAF... no change at all. I was thinking of changing the fuel filter but but not sure how that would explain the noise..?

Then when off the ramp idling there was a very loud pop/bang noise, with the whine/whistle changing to more of a hiss... no smoke though.. So shut it off quickly!, again nothing obvious in the engine bay...

As a 12 + year old car I would just be scrapping it with issues like that.

Do have any fault codes since the problem

It could be the turbo bearings the turbo could be way off line and it does not take much for that to happen

you need p2000 to read codes, it could be a vac issue? Fap and eyols might need cleaning or filling up. have you checked the turbo inlet pipe or intercooler pipe.

Just an update if anyone's interested- turned out to be a totally blocked DPF, sorted and car is ok now (touches wood...)

It's not ok unless you have also found and fixed the problem that cause the DPF to block. Otherwise, what you've done is a rather expensive temporary fix for the symptoms.

the dpf can be removed and cleaned easily. the 2.2 actually runs pretty clean for a diesel as long as no faults.
