Ford Focus Traction Control/ESP -- error light

[planetf1]

I have a yr 2000 european focus 2.0 i ESP.

Last week it went into the main dealer for it's 9th service, and I had the front brakes/pads replaced.

As soon as I collected the car, I noticed the TCS warning light was on. The dealer did a quick check, reset (I think) and I headed off. Then in 2 8 mile journeys the TCS light came on both times.

I returned to the dealer, they took the car in to check wheel/brake sensors and came back telling me it was the lateral sensor, that it was nothing to do with the work they'd done, and that it was a ~ £450 replacement.

I do have a generic OBD scanner, but it doesn't appear to show anything relating to TCS

Any thoughts
- how likely is it the brake/disk replacement could have introduced this error
- suggestions on what to do next

Go back and kick up a massive fuss if it wasnt there before as it sounds like theyve damaged a sensor and are trying to get you to pay for it!

I did get in touch with the dealers head office. Didn't find any strong recommendations for local independent alternatives for this specialist area. One of the directors suggested I take it to another garage in the group to see their top specialist for these systems.

I took the car in today - we went for a test drive and brief exam and I have

C1281 - Lateral Accelerator Circuit Failure
C1282 - Lateral Accelerometer Signal Fault

Taking car back monday for panels to be removed/wiring to be checked -- apparently there's quite a few connectors that may be dodgy that could cause these failures before a sensor is replaced

Nothing obvious with the original work done, but the wheels/sensors are also going to be removed to confirm that work was done properly.

Still worried this could be an expensive repair with labour+parts.
