E60 M5 engine malfunction update
Well I have a progress update now on oil in cylinder 3. Apparently the sizing of cylinder 3 is larger than BMW spec and other cylinders - faulty manufacturing. So we are in discussion about how best to fix here.
Stay tuned for further updates but in the meantime, BE VERY, VERY CAREFUL ABOUT BUYING ONE OF THESE CARS - THERE MAY BE ISSUES AND CHECK YOUR WARRANTY TERMS VERY CAREFULLY first.
