You folks out there used to diesel bug, can you help..?
Is this diesel bug..?
Background: This a a friend's car a 2007 Peugeot 407 2,0 HDI. (sorry)
Last summer he went to Croatia towing his caravan, and on the day of return he filled up at a gasstation at the highway. ca 500 km later when he reached Southern Germany, the car wouldn't pull anymore and engine light was on. Towed to a garage where they said, bad fuel (water.?)
Had the tank cleaned, new fuel filter and off he went the next day. Shortly after the engine light came on again, but he could drive the last 1200 km home.
Have had the car looked at a few month ago at a Peugeot dealer, replaced 2 injectors and the fuel filter.
Last week the engine light came on again and he can feel engine vibrations at ca 2200 revs in any gear. Today he had it booked into a local garage (same place that did my glowplug/head replacement) and this is what they showed us when we arrived. The picture is the fuel filter housing and the fuel filter was completely black and an error code logged regarding too low fuel pressure.
Is this what diesel bug looks like..? (we're not used to that problem around here)
