HI

2007 S Type 2.7d - 74000 miles

I have changed the battery after I got codes U0121 and P1934 - Cannot communicate with the ABS.

I gave checked all wheel sensors, and the car in constantly on a CTek if not being used.

The went into limp mode and neither speedo nor the power steering is working.

Any ideas will be great.

TIA

Cheers
Werner

Stating the obvious, it sounds like the problem could be a wiring issue, something, I believe, which is not unknown on the S-type. Try emailing Tom Robinson or David Marks to ask for their opinions and for common wiring issues on the model. Both have extensive practical knowledge of working on electrical issues on cars of this era. Mike.
