Hi all Landy Lovers,
I am experiencing some severe problems with my Disco 3 TDV 6 HSE Camper / 2007. Basically the car doesn't won't to start at all after I have change the ABS Sensor on the left side.
The typical disco light were flashing on the instrument cluster unit before I started to change the sensor. I changed the rear bulbs, the brake light switch and the ABS sensor as well as the ABS unit.
I took out the ECU/ TCM module to see if the unit is dry which was positive, I thought maybe it is the immobilizer. Something is draining the battery hard but I couldn't find out what it is so far.
Anyway I am trying to figure it out since February and haven't got any clue now. Although tons of threats are written about similar issues and I do believe I made use of nearly all of them. Sadly they didn't work for me.

The following codes are showing up
P1623 Immobilizer
U0001 Highspeed Can Bus
U0010 Mediumspeed Can Bus
U0100 Can Bus Connection with engine control unit
U0132 level control unit
U0140 power supply unit
U0164 Can Bus air condition control unit
U0159 Can Bus connection parking assistant
U0122 Can Bus drive dynamic control unit
U0138 Can Bus four wheel drive control unit
U0184 Can Bus connection radio
B1A00 control unit
B1A81 Control unit navigation
B1A87 engine tailgate

I would very much appreciate if some of you might have any idea what might solve the problems or any suggestions what else I could possibly do.
I did buy a complete cluster instrument unit with keys, immobilizer, engine control unit, ABS control unit and I do wonder if I can replace this package without any harm to any other units of this car, which I do not know or do I have to reprogram anything respectively only with precautions?

Kind regards

Rick
