VW provide no protocol for the testing of the G39 Lambda sensor, they tell you to use Guided Fault Finding which is what the dealers use, I have it now as well but among independents it is rare. The car is incorrectly registered as an EU3 model, this will become a problem when entering the new Toxicity zones around the UK where EU4 petrol is the minimum standard without having to pay a tenner or so per day so you should get onto the DVLA about having this altered. To save a set of items, click on the VAG-COM logo found on the top left corner of the item selection. The Advanced Measuring Blocks now include a Turbo button and the ability to save the list of selected items to a file and retrieve it later. The lambda sensor used is a first generation NTK AFR type NGK - Broadband lambda sensor () This function is available only when a label file exists for the control module being accessed. So, a 2005 model automatic, makes a difference.
