Ok, so I had a problem that now seems to be fixed, sorta kinda. ABS, SRS, trac control and Engine Check coming on intermittently (basically dash going nuts) and as has been discussed elsewhere, replaced the ABS module. All seems fine now after I got another one from Pick a Part. Except that I got the 2nd hand one from a VX that had the same part number, looked the same, bolted in the same etc, and I seem to have lost trac control, ie no response when I hit that button where I used to before. I tested the ABS and it works fine, but for obvious reasons, I am not willing to check whether I have actually lost airbags and similarly if not quite so much trac control. Are there different ones that look the same etc but do/do not have all the features or something?
