Afternoon everyone,
I'm having an ongoing issue with the Defender. Its a 2000 Td5, has a performance upgrade on the aftermarket Bruce Davis ecu.
The original problem was the car would drop into what seemed like a limp mode, not firing on all cylinders, could keep limping it until it got worse and cut out all together. Turning the car off and on brought it back to normal. I was going into the shop to have this looked at ( classic injector harness issues i thought) however we soon found out the coolant was full of diesel (I have another post covering these repairs http://www.aulro.com/afvb/90-110-130-defender-county/230609-big-td5-issues-coolant-full-diesel.html) but basically overhauled the lot, new head and all associated parts and complete new cooling system and fuel cooler rebuild, quite the pricey incident. We thought this would solve the issue as a crack in the fuel rail on the old head might have meant it wasn't getting the flow it should however with the new rock solid engine the issue remains.
It logs faults on all injectors when this occurs. The fantastic guys that I have been working with are adamant all injectors aren't stuffed but it could be one causing a really bad miss which throws the others out. Their suspicions lie with the injectors or the fuel pump. I left it with them for a day and it wouldn't play up for them. At first I thought the issue was more apparent while the engine was under load, I don't tow but do drive on soft sand on occasion but on the drive home from the shop it displayed the mentioned symptoms while taking a right hand turn whilst accelerating and come to think of it this has caused the issue in the past I have just not linked it. So perhaps it isn't the load put on the engine caused by soft sand but the excessive bumping around that could replicate a right turn. These symptoms only really start to appear after at least 30 minutes of driving.
I am hoping to have to back to them for a week next time so they can get it to play up I just thought I'd run this by the veterans on here so if they had any ideas, i could possibly try and diagnose over the weekend such as harnesses rubbed through in certain spots or the like, sensors or switches I can check as this is not the classic oil in the loom causing a miss.
Cheers!
