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 surcharge for the additional cleaning.
Optional Extra:
We are also able to thoroughly clean the Rocker Cover in the Hot Wash.
(Some vehicle need this, and some don't. We can advise once we've removed the Cover).
If you have any questions or would like to make a booking, please Contact Us and speak to General Manager Simon Edwards who will be happy to assist you.
Please note, to make a booking with us we require a £500 deposit for this job.
