Hi I am considering buy a 2004 Z4 2.2 , mileage 61K. At this age and mileage would the car be prone to Vanos issues and if so are there easy ways to check.
thanks

Have the same model/year, done 115k and no issues.
At 61k with a service (oil changes) history you have no worries.

On the z3 with m52tu 2.8 which shares the head and vanos system with all m54 based engines I had a wavering idle problem at part warm which turned out to be vanos seals. My car sat for years doing very little which probably caused it. In my opinion if it starts from cold and over the course of a few min settles down to a stable idle AND you have no loss of mid range torque.. good to go.
