SYSTEM FAULT SPECIAL PROGRAMS NOT AVAILABLE

Hi

I have a irritating problem with my disco3

This message pops up on start and the car also gets limp mode. No warninglight on dash just the message.

I get codes from my icarsoft reader
U0401-94
U0416-94


Once in a while it starts normal but after a while the message pops up and im back in limpmode.

I have changed battery and checked some connectors but nothing have made a difference. Suspension gerbox, handbrake and high/low works perfect.

Anyone have ideas?

Try a better reader like a gap tool, should be some hard codes if you are getting communication errors.

I have read out the codes with 3 different readers and this is the codes i get. Sadly i have 700km to the closet Land Rover dealer so that is not an option.

try doing proper hard reset

mostly those codes are BCM related hard reset might help or solve but not guarantied

if hard reset does not improve things I would start looking at all connectors going to BCM engine ECU and all more exposed for oxidation of pins and stuff of clearly visible harness damage
have you checked you charging level when car operates normally
good luck

Hi

I have already done the hard reset several times, it does not cure the system fault. It is totally random when it comes on or not.

Some times i can start the car with no fault warnings at all (still in limp mode) and drive around with it and the warning message dont appear until i twist the drive mode selector.

maybe gear selector has the issues than since it is kinda directly resulting in fault appearing?

I have been thinking so too, i have a used center console on the way. I will try to swap it out and see if it works

I have been thinking about the instrument cluster too, it might be faulty.

gear selector gathers lots of crap from users and activity around it and not waterproof so i guess if water ever got there at all would defo cause issues

Hi mate like I said mines doing the same thing so I bought a icarsoft v2 cleared all codes and went into limp mode and same message as yours and code came out as p2290 quick google and appears fingers crossed just the fuel filter well I’m hoping it’s that’s as i have never changed it yes since i bought it 8 months ago but was on the to do list 🤞🤞🤞
