W211 ESP warning light fault

[Tradtx]

I did some work about a year ago on my w211 e320 cdi (2007). Ever since the ESP light has been on. At first it would intermittently turn on and off but now it seems to always stay on. With it the cruise control is also gone and the tyre pressure sensor. Gone as in disabled. Got told the hand brake isn't working either despite feeling very functional when pressing with the foot pedal. Anyway, I don't suppose there's anyone near Birmingham with star software that could have a look at this? Do a moving diagnostics on the car?
