Oh dear. I can safely say I won't be trying that myself. Thanks for the heads up anyway Steve.

Thanks for your reply Steve. The diagnostic platform's not mine but I think the reductant related codes will clear as the light comes on when AdBlue's low and then goes out a little while after re-filling. As for the p2002, I'll look into it as you suggest and maybe I should get the DPF cleaned. I'm hopeful that if it comes to it the EGR cooler would be covered under warranty.

The following codes are lurking in the background of my beloved 2.0L diesel A4.: P200200 PARTICULATE TRAP BELOW THRESHOLD P204B00 REDUCTANT PRESSURE SENSOR CIRCUIT RANGE P204F0ON REDUCTANT SYSTEM PERFORMANCE BANK1 The car currently drives well, although I'll begin to feel the pinch if the cost of AdBlue increases. Could someone give me an idea of what I might have to do to prevent catastrophe? Many thanks in advance.
