Peugeot 406 2.2 HDi DW12 engine woes...
Discussion
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...
