Howzit Gents,
Hope someone could help me with a dilemma i'm having at the moment
raise:
I had deleted my Cat's, added Mini-Cat Foolers and a Dastek Unichip a while ago when I did my exhaust, etc (6-8 months ago).
Now I'm reverting back to stock, but i have not changed the branches with the cat foolers or the unichip
Currently getting the following Error Codes:
2C6D CDKLASH - Lambda sensor aging of rear cat bank1
P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2)
2C6E CDKLASH2 - Lambda sensor aging of rear cat bank2
P0159 O2 Sensor Circuit Slow Response (Bank 2 Sensor 2)
29F4 CDKKAT - Catalytic-converter conversion
P0420 Catalyst System Efficiency Below Threshold (Bank 1)
29F5 CDKKAT2 - Catalytic-converter conversion (bank2)
P0430 Catalyst System Efficiency Below Threshold (Bank 2)
Car on - Cold
Car on - Warmed up and Idling (15 Minute Drive)
So what I want to know is, is a O2 Sensor faulty ? or is the unichip messing with my readings ? or should i remove the Unichip and get them to write to the ecu directly @ Xcede.
I would like to get this sorted out properly as I want to get her re-tuned @ Xcede for better fuel economy (e90 320i) and not wishful extra ponies like the F30 320i :hammerhead:
Would really appreciate the advice on the matter above
