I have been having some grief with my wifes' (DIS dead) and it finally looked like I was getting somewhere, until.....
The dash insert I got was a pre-facelift with no boot open warning, whereas hers was a hybrid facelift with boot warning and analogue clock! I was told this at the time of purchase, but was not bothered as it was to test if the faults were dash or car related.
The original dash part number was 8D0919930M, and the one fitted was 8D0919930 HX
I now have Byzans alarm issue as mentioned here Replacing and re-coding dash clocks in S4?
Can any of the participants remember the fix, or give me a clue as to how to disable the alarm for (possibly) a few weeks whilst hers gets tested and then fixed?
The way things are going, it's starting to look like she's going to get something else, and somebody is going to get a bargain deal on a B5 2.5TDi Q Avant with a 30,000 mile engine and Diesel Bob recon'd pump and injectors! (or it'll go the way of my three cortinas last month and get squished with the tractor and weighed in!)
