Do this DIY first then worry about the Vanos seals later.
My car is the same as yours 1998 528i with 110K miles, and it has Single Vanos.
My car runs smooth like butter so I am not wasting my time doing the Vanos Seals thus yet.
When the Vanos Seals go bad, the symptoms are WORSE for Double Vanos cars.

So w.r.t. your symptoms of bad cold idle, do this ICV CCV DIY in this link first.
If it does not solve your problems, then look into the Vanos Seals!
