MOT Failure - How do i get the most money i can from it?

If you want it gone quick, how good are your brakes?

What are the plugs like? oiled?

Atleast check the lambda sensor is working or if you can't do that get one from a scrappie and change it, then either pay for an emmissions test or go back and have a partial re-test MOT (half price) within 10 days.

You'll make the most money selling it in bits, it'll be worth a few hundred like that.
The other option is an engine swap.

I'm happy to be corrected but, when I had this problem, the low lambda reading meant that the car was running rich. It appears to me that the lambda sensor is accurately measuring the rich running of the engine and is sending the appropriate signals to the ECU.

Where your logic is failing is that the *MOT sensor* is reading low lambda which does mean running rich.

The car lambda sensor might be reading high (stuck on high) thus the ECU compensates by riching the mixture.

Ah, I was under the impression that the lambda reading was that of the car's sensor.
