You posted D2 diagrams which have nothing to do with a D1's electrics so i have no ideea what you are after nor where to connect those wires

"Key in" sensor and ignition key interlock solenoid, both neglected in the diagrams... though you should'n have posted with Disco 1 prefix

Sorry, just realised that it's the front passenger window and my last reply and attacchments were for the rear, here is for front which is a bit different as the motor is powered direcly by the ECU so check if there is power across pins H - G of C288 when the switch is operated, if it is the...

Your AC seems low on gas and has a drain tube clogged, as about the window, as long as it works with direct power to the motor and all the other windows are working means that the problem is on that particular circuit starting from the switch, common issue is that the wiring used to be chafed...

Hi, first of all as your profile is incomplete you should be specific if it's LHD or RHD vehicle and to know if you can fix it or not tell on a 1 to10 scale how handy are you with electrics

The problem is that like you can see at position 78 when you get 591 air flow the boost is only 1.28 which is low, at that sucction the boost should be very close to 1.4 just below the overboost limit, if you hear some hissing sound there might be a boost leak somewhere, i doubt that with low...

so what that "blows a lot" means? just be aware that the hotter it runs the less power it has.... check the wastegate to not be stuck open, how many threads yo have left from the locknut on the wastegate rod?

Nothing obviously wrong in those readings except that the coolant temp goes a bit higher than normal, if it's blowing black smoke i doubt it's underfuelled but there can be a leak along the air inlet/turbo circuit somewhere, some important things to clarify: - is it Eu2 or Eu3 engine? - manual...

Unfortunately you can't rely on those fault codes cos Foxwell is not reliable with the Td5 engine management codes that's a verified fact, first of all this has nothing to do with the engine management or fault codes and if you unlocked with the fob it's not immobilised either so first of all...

I couldnt compare them live to see the real benefits but AFAIK the 500070 has some software upgrades for better CDL-TC cooperation and better fault code protocol

The only thing both systems are sharing is the IDM(interior fusebox) no common earth nor headers/connectors as the washer pump is in front aand the wiper motor at the rear, the BCU is involved only in the washer's activity so the first suspect is the fusebox, it used to suffer from corrosion...

SRD000150 is the first upgraded version and the 500070 has even more upgrade.

I can't see any reason for that

If some people didnt have problems means that they were lucky to not get into the worst scenario, if you lock the diff while the engine is running the TC will work normally then if you get stuck turn ignition off then on as the lights to come on and the TC disabled... though even if you'll have...

The TC warning light has nothing to do with the wire i mentioned, not affected, cutting that wire the ECU will not "know" that the diff is locked and the TC can come in conflict with the locked diff in some cases that's all, while the newer ECU is conceived as the CDL and TC to work together
