The first job performed is STEUERN_EVANOS1_FRUEHANSCHLAG -> Command inlet VANOS advance until endstop.
When it completes you get back the SOLLWERT, German for setpoint, and the ISTWERT, which is the actual value.
The setpoint gets always set to -10, the value it expects to see is 0.
I would say +-1 would be deemed good, +-2 would be acceptable, anything beyond that and your engine just isn't in time properly.
After that it goes to STEUERN_EVANOS1_SPAETANSCHLAG -> Command inlet VANOS retard until endstop.
The setpoint here is 75, while it expects to see 60. Again here +-1 would be good +-2 would be acceptable, etc.
Next up is STEUERN_EVANOS1_VERSTELLZEIT -> Command inlet VANOS adjustment time
It returns EVAN_VERSTELLZEIT_FRUEH which is the time it took to fully retard the intake cam, and EVAN_VERSTELLZEIT_SPAET which represents the time it took to fully advance the intake cam.
We consider under 250ms-ish good here, DIS allows up to 500ms before it fails you.
The rest of the test is the same thing but for the AVANOS which is just the exhaust side.
The only difference being the intake ranges from 0-60, while the exhaust ranges from 0-48, same tolerances apply, exhaust is usally a bit faster on the adjustment due to less range.
