π BMW M3 4.0 (2008 β 136,679 miles)
πReason for booking in…
‘It’s my track car and want you to get it back to its best with your service just before I do the oil change.’
π Initial inspection found no obvious issues in the engine bay with no excessive rattles and shakes, but a purr/vibration from the carbon present and associated boom from the back.
π Initial code read found 68 codes present throughout the vehicle, but given the level of customisation it was expected.
π Live data showed all temperature and sensor values showing acceptable figures.
π§βπ§ On with the clean and it soon smoothed out, quietened down a lot and by the end it was quiet, smooth and responsive again with the exhaust boom replaced with a lovely raspy burble.
