Service ESP issue

[markmc68]

Hi all,

I have service ESP message showing on the dashboard along with the ABS symbol and car with 2 lines underneath symbol. Borrowed and connected a Bosch KTS 200 diagnostic tool to it and it showed up as error code C0040 Wheel Speed sensor front right malfunction. Bought a new front sensor and fitted quite easily myself but I am no expert with the diagnostic tool. I think I cleared the error memory as the lights and ESP warning message went off but as soon as I gave the KTS 200 back the warnings return and the brakes feel like they are grinding again when used at very low speed. I take it that is the result of the ABS kicking in when not required? Seems fine at higher speeds. Question is do I try and clear the fault properly on the BOSCH diagnostic tool again or just bite the bullet and put it into the garage to do properly?

Any advice welcome :-)

Thanks

Mark
