Emission Control System Light :-(
Driving along today and this light pops up:
I gave the car a vagcom scan when i got home and it come up with this:
16804 - Catalyst System: Bank 1: Efficiency Below Threshold
P0420 - 35-00 - -
Readiness: 0000 0000
Could this all be related to my other threads:
The difference now is that the 17705 code didn't show up (maybe because I've not been booting the car around) this 16804 code is no longer saying “intermittent” but now says “Readiness: 0000 0000”.
I'm guessing its time to change the pre cat lambda sensor
Any ideas ?
