ESP + ABS lights on

[safjar]

Hi all,

Just after some advice, my ESP and ABS lights are on. To start with it was intermittent, it would come on when I started the engine and after a minute or so they would go out but now they are on permanently.

I've had it plugged into a diagnostics, 2 fault codes come up.

290 - Wheel speed sensor, rear left - G46. Mechanical fault. Sporadic.

493 - ESP sensor unit. Defective.

Had anyone had experiences of both these? I'm guessing new wheel sensor and either rebuild or new ESP unit? Sounds expensive lol.

Cheers
Marc

ABS/speed sensor would be first choice, looking at around £40/£50 for a genuine item, otherwise non OEM parts can be found for around £15/£20 online.

Sounds like it could be perished and be be splitting into two pieces, starting to throw up the fault.

Thanks for replying. Would that be an easy replacement? Would I need any specialist tools?

no just be careful not to break the senor when removing it ,they get seized in

Sorry for the late response, only recently got round to sorting the issue as I replaced my brake discs and pads at the same time. Replaced the electrical sensor and the fault was still apparent, spoke to 2 independent VW/Audi garages and both immediately said the fault was the wheel bearing, as the sensors use these for a pick-off. Wheel bearing was replaced (old one looked knackered on inspection) on Friday and had no problems since. Nice cheap fix.
