Some progress today.
I fitted the pedal box to the car with the extended mount for the new throttle pedal.
It resides under this lot
It requires removal of the servo master cylinder assy on RHD for certain. So i am going to need to bleed the clutch and brakes. On the plus side, she was due a fluid change....
While the loom was out i did the ICM delete with the B6 loom section 1JO 971 658 L, much cheaper than the repair looms you get.
I chose a loom from a 2000 Passat / A4 as it was sort of an in between model. Still had dumb coils, but no silly second Lambda probes or SAI etc.
The loom i used was 8D2 971 072 FQ. It plugs in directly to my 99 Facelift car loom with 99% the same connections.
This does come with a few problems like it's still a narrow band ECU, it is however still ME7 and fully flash-able and readable and tweak-able using Unisettings and the like .
I have added a connection for the engine light, from the orange plug to the blue dash plug pin 13.
On that same plug there is 2 black/blue wires, but the car side loom only has one, so i have bridged them to allow 12v .
The new loom expects to see the combined sump oil condition / temp sender . I checked and the wire that goes to the dash is the same for oil temp on both looms, so i just made the connection fit my old style sender.
The MAF housing is different orientation to the old AEB/VR6 Combo i had previously.
The new style CTS was also required.
And a position welded to my FMIC pipes for the MAP sensor which would normally live on top of the OEM SMIC
May have added a boss for WMI while it was being done.
Throttle body needed to be changed to a DBW one, Not the studs, i found the normal TB bolts were too short so i made do with some studding and nuts i already had.
My chosen ECU is
4B0 906 018 AA Me7 ECU. Has so far read fine via Galleto and VAGcom
I had to add a N249 valve, even though i am not using it as such, the ECU needs to see the electrical connection.
The next hurdle is the Lambda sensor, even though both my car and the new setup are narrowband there is a difference of connection
For now i will splice it in, but will buy a new sensor, my old one has done 140K, so is probably passed its sell by date.
Now, here we are. Mostly together but..
She will not start, i can access ECU via Vagcom and it throws a code for faulty ECU relay 17925. I have a new one fitted but it seems that the 109 (1J0 906 381A) designation is incorrect despite the spades being correct.
I have ordered a 30 (165 906 381) for collection tomorrow, fingers crossed as i am too far into this to go backwards now.
Excuse the "snaps" lol
