[s-cars] Question about VAG-COM

[joeamund]

Konstantin!
You can read(on your 93 S4) real values(as the ecu sees them) of
temps,ing.timing,boost,barometric pressure,intake temp and so on  according to
tables written in Bentley. A lot easier when fault finding to se what actually
is going on.

Perform output test while engine is shut off and ignition on, for
injectors,fuel pump,idle valve,evap valve,wg frequency valve etc. Check all
functions on AC as output tests while engine is shut off.

As for 95-97 S6 with digital instruments and IMMO set service indicators,
adapt new instruments, program various functions on central locking system
etc.

Perform real time data logging, ie show file later on a spreedsheat when
accelerating for example, then analyze boost,ignition, intake tempe etc.

I'ts a lot more  than  a cool tool, and is probably the cheapest and  best
tool you will ever buy for you garage.
