Evening Guys,
Apologies not been on the forum for a week or so.
Car is running okay, starts first time on the button, fires into life and idles nice and smooth, I really like this car. So a few updates:
EGR Blank, I fitted the blanking plates myself, the car was practically un-driveable as you needed no other cars on the road before you pulled out of a junction. After messing about trying to see if the egr valves were actuating I found one was completely dead by putting 12v on it and getting nothing back, the other one you could hear it actuating when 12v was applied. I bought the blanking kit based on the cost to replace 2 egr valves. Totally transformed the way the car drives in that you can pull out and it will shift to get you up to road speed, however as one of the valves was dead the check engine light was permanently on. So I got the egr system deleted, no check engine light now, no egr codes stored. I did not remove any valves, I did remove the pipes but still have them, so could re-fit for MOT if required.
Still got an engine system fault flagging up which is more annoying than the CEL as it toggles on the drivers info display every few seconds. K Motors checked and sorted the actuator arm, so I can rule that out for now. Strange thing with the code is that when you clear the error memory, as soon as you start the engine the code comes back, this is before driving the car and putting any load through the turbo so if this is a genuine turbo issue how does the car know at idle when no boost is required. Also, the turbo is a mechanical lump, what sensor could be flagging this code, the signal amplitude.maximum part of the message must come from some electrical component somewhere in the system.
I'll check the MAP sensor tomorrow, guess there is a write up on disco3 forum. Going to Belgium in it tomorrow, setting off just before midnight so got some time tomorrow to have a look, I'll check the fuel filter as well, it was on my mind to put a new one on, they are really quite cheap for a decent one.
Lynall, what you describe about the behaviour whilst on cruise is exactly what I experienced, held 70 easily but as soon as I hit a mild incline it seemed to drop a couple of mph.
I also agree with the comments re.getting it mapped. I've always resisted getting my cars mapped or chipped as it was called in the 90's Cosworth years, just figured on this car it may help with performance and mpg. I think I'll re-consider when I've got to the bottom of the potential turbo issue.
For info, I asked K-Motors to quote for brake fluid, ATF fluid, front & rear diff fluid and gearbox oil/filter change. £579 for the full fluid service. Think I've said before I'll do the engine oil/filter every 6k, fairly straightforward job and oil/filter reasonably priced.
I'll update on any findings and after I've done 1500 miles in it over the next week.
