But if i leave it for say 10 mins it fires up straight away any advice would be nice cheers (BTW its my 3.2 ex plod that is having the problem)

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.

yes mate just rung the other dealer near to me and he quoted the part number you gave me  :y at £42.63 The thing that annoys me is that both dealers are the same group i always have trouble with the nearest one . Saying that the guy in the second one is really into his omegas so guess it`s lesson learned Thanks for all you help just one more thing will the light go out with a new sensor or will it need resetting

If it doesn`t extinguish straight away, should disappear after about 20 "clean" starts :y
