Another quick update.
Visited big Russ today over in liversidge
Cleared a load of fault codes that were stored, he test drove the car while monitoring the wheel speeds and found it to be okay. Battery voltage shown in t4 was fine too.
Couldn't get the abs or brake fault to flash up all the time we were there (sods law!)
So.. at this point Russ has advised I check the engine bay fuse box which I'll do when the weather warms up if the fault shows itself again.
A huge thanks to Russ for the time he gave today. Very knowledgeable friendly fella
Thanks
Rob
