I've just had a warning light come up in the rev counter side dash. looking in the manual it's listed as the exhaust gas warning lamp mentioning the lambda sensor? but looking on he web there are 2, 1 pre cat and 1 post cat. The car seams to run fine, idle and under acceleration. Is it a case of plugging it in to diagnose it to get the code for what the fault could be?
It couldn't have come at a worse time
as I am using the car on Monday to go on a family holiday for a week. Is there anybody that could help or have the equipment (Leicester area) to diagnose what it could be?Car is a 2007 B6 2.0 Tdi sport, BKP engine with 88500 miles.
Thanks in advance
Karl.
