ive got a 2003 D2a HSE auto 170 000 on the clock full service histroy.
ever since i bought it it has used excessive amounts of diesel! my average is now 18L/100klm...
with stock ecu map in 18L/100 with a BAS map in 18L/100.
towing my 850kg camper still 18L/100.....
the disco has sliders, a front ARB sahara bar, no winch, dual batts, rear draws(10kg) and a full length roof rack(35kg)
the tyres are 255 70 R16 km2's (25mm taller than the 255 85 R18)so i doubt weight and gearing have any part in it.
it has an egr blank kit, sillicon intercooler hoses, modified OE exhaust(no OE mufflers or kat, has 2x 330mm hotdogs) finer filter air filter (foam type)
ive just replaced the
CAS, tried it with and without the spacer
new OE MAF, MAP, boost modulator and have tried 2 second hand IAP sensors.
new britpart injector harness, there is no signs of oil at the ecu at all, even behind the white plug cover piece.
ive even checked the injector codes were correct and tried a second set of injectors!!!
the rear diff has been replaced disc to disc, the front center has just been rebuilt, all bearingd and break callipers were checked
also.
the auto has been serviced in the last 10 000k's(oil and filter) and shifts and locks as it should.
i have a nanocom and often check the engine values, nothing seams out of limits.
i do have a mis at idle, a drop of 50-80rpm at uneven intervals...this has gotten worse since the new inj harness and CAS and spacer.
motor dosnt use oil or coolant...
the egt's max out at 750deg stock map and fly through 850deg with the bas mapping
the fuel pressure i get between 3.8-4.2bar.
about the only sensor i have to replace is the speed sensor in the auto..
any help would be most welcome!
