“It is really distressing that life has so many up and downs. I would dream of a life that goes up always. But real life is different.”
I started with that as it truly sums up the grand relationship you will have with this car. One would dream of a life where there are only ups with it. The ‘M’ cars are described as exhilarating, iconic, jack of all trades; track and street “ultimate driving machines” and they truly are but, and yes there is a but, one has to be realistic when purchasing or maintaining one for, lets say, a lifetime of joy.
Nothing kills your passion like a six digit bill for an engine replacement or rebuild.
There are a few things you would need to do to keep the passion alive.
Firstly no matter what service annually, weather you make the mileage in a year or not.
Then there would be a small list – take heed;
- Big end bearings drop the sump and do a set before you get to 90 or 100KM. Time wise possibly every 5 or 6 years. See picture below.
- Have the electronic oil level sensor changed, it’s electronic and not knowing how much oil is in that engine is plain asking for trouble. Models 2006 upwards.
- The vanos pipe – special steel pipe V10’s
- Don’t ignore faults, prevention is better than cure, Engine lights etc
- See M3 E46 – First time client so there was no warning him, possibly the worst I have ever seen, ran a bearing – could not save this engine.
See M5 V10 – The car came in for a service – We saw metal fillings in the oil cap and advised the client to do Bearings immediately to save the engine, fortunately the crank was fine.
- Refresh gearbox oil every 40000KM
- Refresh diff oil every 40000Km
- FM booster additive for noisy diffs – developed and sold at BMW
The Tune-Tech family owns an M5 V10 E60 and they race a M3 V8 E92
There’s probably not much that can surprise them on these cars as they have seen it all and done quite a bit to them; mild to wild conversions.
The M3 V8 race car has a custom build 4.4 engine in it – I am not authorised to mention power figures.
Side Note: Currently fitting a DCT gearbox into the M5 – the box it probably should have come with. Keep you posted on this modification.
