Thank you! I will reach out to a few ADAS places and see what they can do/offer.

If it was an alignment issue would it intermittently work? If for argument sake, the radar was not getting power (or faulty) would it bring up an error? Would it still engage cruise control? I was whinging to my mother and she suggested an auto electrician?

I don't mind getting my hands a bit dirty, though my skills and expertise is limited (translated to I don't want to break anything LOL).
In terms of scan tools I do have a cheap and nasty bluetooth tool would that be able to see if any codes are being produced by the system? If you can recommend any I don't mind forking out a bit of dosh.
