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.

Optional Extra:
We are also able to thoroughly clean the Rocker Cover in the Hot Wash tank for £35.
(Some vehicle need this, and some don't. We can advise once we've removed the Cover).

To make a booking for this service we require a £500 deposit.
