I had these errors.
Started with faulty key module, then brake light switch shorted, then ABS said pressure sensor fail.
All sorts of warning like belt and airbag came up.
I fitted 2nd hand ABS unit, no coding required and replaced key reader and brake light switch.
All working, but tpms doesn't work.

So got hold of a cable and ISTA plus. Tricky to install but was all good on the end.
Started car and the check engine light was still present. Successfully connected the laptop and did a full scan.
Weirdly the data showed the car as a manual. Lots of colours showed up.
Both of the red alerts were related to MOST and seemed to be for unable to contact the cd player. Which makes sense as Dave coded a CD changer into the car in order to add the MMI box. So not sure if these can be resolved.
Anyway didn't have time to do anything else with this so disconnected.
I then noticed that the engine light had gone out. I didn't do anything else other than run the scan.
Took the car for a short spin fully expecting the light to come back on, but so far it has not.

an update.
Engine light still didn't reappear and car was running perfect. Keeping any journeys very short and local at the moment in case of issues.
Took her for a short drive to pickup a parcel and got her cleaned as well. Looked great and started the 2mile drive home. got about half a mile from home along a dual carriageway and same thing happened, however this time it went into neutral and i couldn't engage any gears so couldn't even limp home. Couldn't get into park and was stuck in neutral so i had to engage the handbrake and called the AA.
After about 15mins i tried her again and she fired up and even though all the lights were on, she was engaging gears fine. got her home so i now need to run a full diagnostic as soon as i can.

i have done a full scan and again the engine management light has gone off and the errors do not seem major but all seem electrical, it does not help that i dont really know how to use ISTA.
Anyway the engine management light has gone away and the car check says no errors.
ISTA errors are as follows
CD Changer error i expect as it was coded in by AnubisZed when installing the MMI box
High beam assistant seemed to work last time I used it (about a week ago), but i guess it could be faulty
PDC was working when i parked the car so again unlikely to be faulty.
All pointing to electrical, might check the MMI box and ensure all connections are secure. Need to do a firmware update on it anyway. Its just getting the time.

You are going through the typical stage of denial! I already told you I went through the exact same, the issue and what the fix was. After my first experience with this I blamed the battery, changed to a new one and all was well for about 6months! Then it came back, seems like it’s a progressive decline until the module just stops, I have experienced this with each and every module I’ve had to replaced.
I am biting the bullet and going to replace the ABS Module. The symptoms are becoming more frequent now and looking previous posts and some other YouTube videos it seems that this is my issue.
Just a couple of questions to anyone who has changed this module themselves. Is this a simple part to replace? For someone who is not by any means a competent mechanic. Happy to give it a try but is it something that I should leave to someone more experienced? I have seen some quotes into the thousands.
Also it is difficult to find a new one and the ones I do see are very expensive. Is it advisable to go for a used one (usually go for new due to the chance that the used one could also develop a fault). Would you recommend used or should I go for a new one?
Sorry for all the questions but I desperately want to use the car but at the moment I can't trust its not going to break down.
