[Help! My EPC (Emissions) or CEL (Check Engine Lamp) is on.]

I have a 1.8T ARX engine 4x4 elegannce 2003 plate car.

 

I keep getting the lambda light. Have replaced the secondary air pump -- was busted, and replaced some of the rubber pipe between the air filter and the engine, so there is no leak.

 

Can anyone help??? (see fault codes below)

 

I did a VCDS scan and here are the findings:

[How to: Replace Coolant Temperature Sensor]

HI, Do you know where I can buy them? Thanks

[What's quicker?]

Powerline may be flaky if the wiring in the old part of the house is not good. Have tried it before with variable results. You may wish to try them out first before buying.

 

A future option would be to put a cat5e /cat6 cable upto the point where the new extension is and then see how you could do the rest of the cabling later.
