Last week the xk8 displays DSC system failure display along side the ABS warning light. It did this when I first test drove the car at the dealer, it turned out the right hand front wheel sensor - this was replaced and all was well.
Thinking it may be the same problem reoccurring, I was puzzled to find on checking a couple of days ago in addition to DSC failure, the handbrake light on all the time, low brake fluid warning light(level ok), speedo not functioning and engine management light also on.
I put a new battery on as suggested in a search, checked and cleaned battery cable terminals and did the hard reset, all have no effect. I've now ordered an icarsoft i930 jaguar specific code reader, I'll report back when I start to use it.
(I should add that the car is out of warranty from the dealer and I try to do all the maintenance myself)

Well, I hooked up the scanner and entered jaguar model and year but it kept coming up with communication failure with ecu on a completely random basis.
Eventually after much trying, I managed to get the following codes - U1041,
B1446, B1875, C1300 - does anybody know what these mean ?
I've cleaned the OBD11 port with contact cleaner to no effect, this scanner was bought with the intention of getting diagnostic help, I'm starting to think I've wasted £90...
