ISTA- Vanos Solenoid Valves values - tommyarbi - 20-04-2019
Can anyone be so kind and explain, do I need to replace all four Vanos valves?
There are screenshots after bleeding procedure in ISTA+

OK, I would probably ignore this, It can sometimes take repeated vanos bleeding and driving to get them working, you might see them coming back one by one.
If they don't return, it is more likely the vanos oil pressure feed line inside the front timing case cover.
