loads of warning lights and no speedo on 2.4 c6 what could it be

[jemis]

after having the front wheel bearings chged on my 2005 A6 I now have just about every warning light up on the dash a dodgy handbrake and no speedo, anybody have any idea what went wrong?

 

[jemis]

would I be on the right track thinking they have broken a sensor or cable to a sensor

 

[murran]

what warning lights exactly? abs? traction? esp? brake pad wear?

might have damaged an abs/pad wear sensor.

speedo is driven off a sensor on the gearbox tho. dunno how they might have managed to damage that changing wheel bearings.

take it back and complain. get them to code read it etc.

Damaged speed sendor I would say, not 100% here mind, but ABS, ESP and speedo all rely on the speed sensors for their readings.
