Issues have got worse now, keep getting engine management light on with traction control warning. Revs won't go above 4000 rpm, idle is lumpy, misfire and it is difficult to start. OBD pointed to a camshaft sensor fault. Replaced with genuine VAG part but still showing same fault. Any help would be appreciated as I use the car for transport to work as ambulance crew (60 miles round trip)

Last week my local mechanic replaced my rear hubs but coudnt repace the fronts due to not having the VAG bearing tool. Once the toolarrived the bearings were changed but with some difficulty. after replacement, on starting the car, it was missfiring, the traction control light and MIL light illuminated along with the ESP light. OBD code indicated that the camshaft sensor was at fault. I've replaced the camshaft sensor (030907601E) with a cheapone from the internet but made no difference. I have searched the forum but could't find anything. Has anyone had this issue before? I run a Feb 2014 on a 63plate 1.2 Skida Fabia 6 valve Enging code CGPB TIA
