So I've been having some problems with the Croma (1.9 16V 150hp DPF). About a month ago going to work (about 10 miles down the A14) mostly through roadworks at 40 MPH. Coming out of the 40 limit I accelerated (not hard) and it just died, engine light on and then engine cut out. Pulled to side of road, turned off and it re-started OK but MIL still on. Got to work no further issues. Only thng of note was that I'd refuelled from very empty to brimmed that morning. Check of obvious stuff at lunchtime revealed nothing. Dive home was OK until 1/2 mile form home pressing the accelerator to go up a hill and it died again. Restarted and got home. Put MES on it and multiple failures recorded including high and low fuel pressure. I suspected a blocked fuel vent but no hiss when tank opend. So drove for a week with MES logging but the one time it did it again the laptop hd gone into standby because I hadn't plugged the power adaptor in. No more issues (until today). As the car had sat with the tank empty over the holidays I did add 200ml of isopropyl alcohol to the tank to dry out any water. (there was none in the fuel filter drain though).
I also ordered a Bosch fuel filter element. So fast forward to today. Filled tank to about 80% (first time since having issues) at same pump then drove into Cambridge (12 miles) including the roadworks on A14 and some 70 MPH driving. Stopped for about 15 min and drove back with no issues. A couple of hours later I drove to Soham (25 miles) again mixed driving, with no issues. I was stopped for 30 minutes then tarted to drive home and about 5 miles down the road on a slight hill it died in the same mannar a last month. I waited a minute, restarted and di about 2 miles before it did it again. So I opened the filler cap, no hiss, and put it back. Less than 1/2 mile, died again, took cap off completely nd did another mile before the same thing. At this point some tests indicated that when staionary revving the engine hard would cause it to die. This was a safer spot, I was on the A10, so waited about 5 minutes and managed to get back home driving gently (road works helped). Close to home with no one bhind me I floored it and sure enought it died. At home I put MES on it and again had High and low fuel pressure error codes and some others including C-CAN. Reset and went for test drive in village and floored it, same effect and codes. I thought some of the codes were due to the engine dying rather than root cause. Reset and drove on 1/4 mile later, uphill it started to loose power so I lifted off the throttle and it recovered. I got a MIL but it didn't cut out. Got home driving gently and checked codes. This time only Low fuel pressure signal reading improbable. So now looking at :
Filter, Low pressure pump, low pressure sensor, Tank vent or fuel return pipework.
I changed the fuel filter an the old one (about a year old) was dirty and there was some dirt /dark fuel in bottom of housing. The old filter had a non-pleated, non-woven fabric surface, The Bosch is conventional pleated paper.
We will see what happens next, long trip tomorrow.
Anyone seen anything similar?
