The Euro 3.2 Z3M Vanos has a reputation for fragility. Usually a bill for £3k plus is expected when a new unit is required. We have rebuilt and fitted a large number of these units with excellent results and long service life

  • A failing Z3M Vanos can cause a rough idle and lack of power throughout rev range.
  • The ‘growling’ noise is not always a sign of failure, however it’s not a sound a high-performance engine should make. This noise will come back without changing several key parts, and custom machine work. Not just a seal kit.
  • Once a Mr Vanos unit has been fitted, we fully expect it to last the life of the car.


Common Problems:

  • 1996 – 1999 Model
  • Power – 321 BHP
  • Piston Seal Failure
  • Intake Gear ‘Growling’
  • Solenoid / Seals Failure
  • Snapped Pistons
  • Solenoid Cover Bolts Shearing

What do we do??

The Z3M Vanos is completely stripped down and cleaned thoroughly. The oil pump is rebuilt and all of the internal composite piston seals are replaced. Both solenoids are tested and then it is rebuilt using Viton O-rings and High Tensile Bolts.

The gears are modified to address the rattling.

We will sign off the unit as complete following a bench test of 1hour at 150psi.

Supply and Fit

We can either, recondition your unit after you have sent it to us, or supply and fit a reconditioned unit at your address.

This can be completed in one day and we are available 7 days a week for this service.

Mr Vanos offer valve clearance checks while your car is being repaired. 


The warranty for the Z3M is 3 years with a lifetime vanos noise warranty
