2011 XFR 65K miles, I just brought the car to the dealer for the air bag recall on the passenger side air bag. I also had a new wheel placed on the back driver side (the original wheel was slightly warped). I brought the car home Tuesday and just drove it Thursday and ABS, DSC,E-DIFF, Adaptive Dynamics faults all came on. Could these faults be on because of either of these repairs? It seems a little coincidental.

 

First and most obvious culprit is a sickly battery which could somehow have been drained by or during the repair work.
Connect a battery tender, let it run for a few hours maybe even overnight, then see what faults do or don't appear.

 

Will I hook the battery tender on both posts? I know that when jump starting it, the manual wants you to place the negative on metal not the negative post.

 

There is a never ending debate about this and no definitive answer, some say connect the negative lead to an earth, others say connect it to the battery negative terminal.
IMHO it makes no difference at all, just go with whichever way is easier for you.

 

Normally it makes no difference, but if battery gasses are leaking out they are flammable and sometimes even explosive and a spark can cause quite a problem. Making the last connection (which often causes a spark) as far away from the battery as possible helps to prevent that.

 

Almost certainly a battery issue. Follow the advice above. But if you don't know when the battery was last replaced I'd suggest doing that. It's quick and not expensive - and low batteries give lots of niggling issues.

 

I plugged in a code reader and the wheel I had replaced by the dealer two days ago (because of a slight warp in it that you could only see on the balancing machine) is now showing code C0037 left rear wheel sensor but when I called today the dealer said no way they could have caused this print a new wheel on. I don't believe this is a coincidence.

 

Not sure if this is relevant, but every time I had my car dyno'd it would throw all those codes for about 20 miles. Maybe the wheel sensor is causing the same type of errors?

But I agree to check the battery first.

 

Same here, including the F-Type.
Modern Jags don't like being run on a dyno as the wheel sensors detect that the rear wheels are spinning a lot faster than the front wheels (duh) and it causes them to have a fit and throw all sorts of codes.
