Hi All, I have had a breakdown and would appreciate any advice from the collective experience on the Forum. Any advice gratefully received!
Van: 2007 Mk7 SWB T260 85 2.2 TDCI FWD. Reg: KV07 LBK. 145,000 miles. fully serviced every year.
Short History:
Van has always had a rough idle and tendency to stall occasionally at junctions, especially when warm, for the 4 years I have had it. But NEVER ever let me down, been 100% reliable, always starts 1st time, my garage never able to do anything about the rough idle and occasional stalling issues!
On Friday I nearly ran out of Diesel after the filling station I was heading for was closed, limped to the next one on vapours. Van running rough and stalling more than usual for the last mile.
After refuelling (only to 1/3 tank, due to being skint!) van was rough and continued to stall more than usual and was hard to restart on several occasions. It also had a power flat spot at around 2000rpm. Felt like the engine cut out and then cut back in again every time I went through that rev band.
Unfortunately needed it for my weekend job over the weekend so had to keep going, even though it clearly wasn't well!
Saturday Night, (Approx 100 miles motored with a heavy load since filling up) the van stalled for the final time and would not re-start. Still had about 1/8 tank of Fuel in it.
Called the AA, he put some extra Diesel in even though it was not empty. Still wouldn't start.
The van started and ran when he sprayed Easy Start into the air intake but stopped as soon as he stopped spraying it in!
He Connected the Tablet and view live data which suggested the van was looking for 60psi on the Fuel Rail and was only getting 9psi
AA man called it a failed fuel pump and van was transported home on a lorry (It had valuable business equipment in it which needed offloading at my home).
He has provided me with these fault codes....
Patrol found the following fault code/s:System : Engine control 1 - ZZH / Diesel CR/EDC DEN C1.1P0191 - Rail pressure sensor. Error Message : Outside specified range.U0167 - Communication with immobilizer. Error Message : Malfunction.P1103 - Air- mass sensor. Error Message : Signal too high.P2635 - Fuel pressure regulation. Error Message : Malfunction.P068A - Main relay. Error Message : Shutoff too early.
(Van has blanked EGR valve so Engine Light is always on)
I am assuming my running on vapours has dragged some dirt through the system and either completely blocked the filter, or damaged the pump.
My first thoughts are to try and flush the fuel line, change the filter, try and drag some fuel through the lines and then try running the engine again and then only go after the fuel pump if its no better.
But I would appreciate some advice if anybody thinks this is a classic set of symptoms or if this is screaming a known problem etc.
Also pre-empting a new fuel pump, my Van is old and tatty, not worth a lot, but I need it and can't afford a new one. Should I go for a 2nd hand pump off Ebay or a recon unit. I don't think it is worth a new pump. Also would appreciate advice on the best place to get any EEC re-learning that will be needed after a repair.
Best Regards,
Will.
