PLEASE NOTE:
We're finding some E46 M3's with extremely dirty/stained/clogged/tarnished Cylinder Heads (due to incorrect oil grade, poor oil quality, or extended service intervals).
Some vehicles require the Cylinder Head to be chemically cleaned in a Hot Wash bath twice (or even three times).
If this is required on your vehicle there will be an additional £80 surcharge for the additional cleaning.
