Hi peeps
Ive got the below fault on my Ibiza Cupra 2002 (ayp)
Any of you had this before?
My car drives ok and boosts as normal but the CEL light comes on now and then
I have a Blue Flame full exhaust system
16804/P0420/001056 - Catalyst System; Bank 1: Efficiency Below Threshold
Possible Causes
Oxygen Sensor(s) defective
Oxygen Sensor(s) Control defective
Possible Solutions
Check Oxygen Sensor(s)
Check Oxygen Sensor(s) Control
Perform Oxygen Sensor(s) Aging Check
Special Notes
For 1.8T's experiencing this fault code, this thread may be useful: http://forums.vwvortex.com/zerothread?id=663057
The vortex thread states it may be a leak from the cat or a dodgy sensor
Any ideas?
Thanks
Matt
