Hello, my friend has VCDS cable and next week we will look for used cars with 2.0tdi CR engine. Do you have any checklist what to look for after auto-scan?  For example what channels are for injectors, dpf, egr, map, maf, adblue;  what should be the values, and anything you can think of.

Channels vary according to the model and engine type, no point in quoting a number, also the descriptions change often akin to a cryptic crossword puzzle clue.

 

Looking through the thousands of channels which only present a few at a time in a miniscule text box I can find a dozen if not more for the same parameter with varying descriptions, only one of which will have data for my vehicle the others bring up nothing.

 

Same deal with quoting values, they units change and often the data will not even correspond to the supposed unit of measure.

 

Other than doing further investigation led by fault codes I would look at DPF differential pressure (back pressure) the measured not calculated value of soot compared to how many kms since last regen which will probably be shown as meters despite the units being kms, ignore the ash reading be it volume or weight as its a fantasy estimated figure and may have been reset to zero in the past.
