Same codes as before or any new ones?

From previous codes, it's not happy with the bank 2 sensor 1 Lambda sensor and bank 2 knock sensor.

P0430 is a cat efficiency code that can be ignored for now.

I would check the wiring to the knock sensor on the passenger side is OK and plugged in for starters. Any sign that the engine loom has been hacked about with during plod decommissioning?

Knock sensor shouldn`t give starting problems, should idle and run OK just a noticeable drop in power

Just had to replace a knock sensor on mine, as Rob says down on power, fuel consumption up and eml showing.
Replace sensor, reset light and all's good.
I can see it being interesting to replace the no2 sensor though.

Doubt it, mine was starting and running fine.
I believe the ECU uses a default setting when it detects a fault.

Strange thing is the starting seems ok now . I`ve bin run ragged by her in doors today looking for a new cooker and it started and run perfect all day was just on the way home and on came the light i`ll double check the codes later i`ll also check the wiring but ive had the car nearly 2 years now so doubt its the wiring but you never know
