Hi gurus
I have switched from P38 4.6 to L322 (TD6 BMW Diesel, year 2003) a year ago. Happy with the ‘upgrade’ but misses the V8.
The L322 has been running like a clock until a few weeks ago, where the problems started…
Symptoms:
I first noticed a brief loss in power/stuttering when travel at same speed for longer periods. It disappeared when I increased the speed and would sometime reappear if I held that speed for a longer period.
When coming to a halt the revs would go up and down randomly when idling. When I started accelerating the problem would disappear again and reappear when coming to a halt again. Sometimes to a point where the engine would cut out and hard to start again.
Yesterday the car wouldn’t start at all. Just cranking over.
I have changed the fuel filter but it didn’t solve the problem.
My GAP IIDControl diagnosis tools give me these errors:
P1180-01: Low side fuel pressure sensor plausibility (fuel filter) - reduction in quantity due to low pre-pressure - General failure information - general electrical failure ///
P0193-02: Fuel rail pressure sensor malfunction - short circuit to battery positive - General failure information - general signal failure
When idling my low pressure pump shows 3.9bar and fuel pressure approx 350bar (dropping to 260bar when the problem occurs)
Fuel comp for the cylinders are (order 1-2-3-4-5-6, units mm3): (0)-(1)-(1)–(-2)-(-5)-(-5), but varies when driving. Specially cylinder 5 and 6.
It’s my first time working on this diesel engine and I’m about to order parts today and could really use some input to where I should start looking for the cause and eventually what parts to order.
It would be fantastic and I would appreciate some guidance from you gurus…
Best regards
