Hi, I bought the M62TU vanos solenoids off rockauto $33.79 USD each, they work just fine and i've used them for about 90 days now without any issue.
ULTRA-POWER 2T1078

However I did have to apply some loctite GS2 on the sealing face of the flange gasket due to some weeping before I corrected the leak issue. I decided to re-use the old flange gasket instead of getting one new.
And I needed to get the special vanos socket off ebay, it was not expensive.
