    ive just took her out and the TC light and the abs light is on. When i reversed out my parking space i turned the wheel slightly and i got like a soft constant vibration through the wheel as if something was up with the power steering. Now all the disks and pads are new and im not sure when the PAS fluid was last changed. Also when braking im getting the feeling as if the pads are real low, its not always, only at low speeds. Can anyone advise me. Thanks guys

    sorry yto stae the obvious m8 but :

    not present means its not hapning the now
    present means its hapning the now
    and intermittant means it happens now n then.

    clear all codes, then take it a run and try again.. those couls have been old codes

    also:

    ABS and TC could mean that the sensor wire is unplugged or damaged at the hub
    The coupe...ITS ALIVE & back from the dead....again!

    ahh so not present means theres a problem but not at that second, present meaning the problem is now. And intermittent meaning a mixture of both. Its ok i just didnt get it lol

    I did clear all the codes twice and these are the ones that come back.

    With regards to the TC and ABS problem, i checked the sensor when the wheel was off and all looked fine, are there common faults with these?

    Do u think the ecu is blaming its own fault on other things?

    The ABS sensor is inside the hub so you cant 'see' anything.
    The truth is always the truth even if you haven't realised it yet...

    The abs is built into the hub, so you need to replace the whole wheel hub

    Here's the hub from LMF
