🚘 One for the B58 fans here and if your not then this 3 litre, straight 6, twin scroll turbocharged, xdrive 330+ bhp convertible came to us for a few issues.
😲 Fun fact incoming: The new generation Toyota Supra also comes with a B58 engine 💪, now back to the topic.
🤔 This pocket rocket convertible came to us for a ZF8 gearbox service due to holding the gears a little and brake pulsing on moderate braking.
✅ After a test drive confirming the front brakes need attention and the ZF8 gearbox was holding back a little, it was front wheels off and brake service.
✅ We found the disc to have built up a rust lip and pads had collected debris due to the disc.
Both discs cleaned up, pads/pins cleaned and lubricated and built back up.
✅ We then serviced the ZF8 gearbox to spec, checking the temperatures and using the correct ZF8 fluid (If you DIY this, don’t use normal ATF or non ZF oil on these gearboxes as you risk breaking them🥲💸).
✅ New filter and ZF sump casing (comes built in), bolts torqued to spec and following the procedure of the service.
🤔 Another fun fact: BMW themselves say this is a lifetime oil 👎, unfortunately it’s just not true and should be serviced around 60k miles or 6 years, whichever comes first.
BMW won’t pay for a repair if you decide to try the lifetime route (unless under warranty) 🤣.
🤷 If you are unsure if your ZF6/ZF8/9 needs servicing then give us a call or message and we can check for you and provide a very competitive and thorough service.
🩺 Symptoms are usually a slowed gear change, holding or hesitation of gear selection and usually lack of smooth transition into gears.
🛞 After a test drive this convertible was back to insanely rapid, smooth gear changes and responded faultlessly to the different modes along with the brakes being just like new.
☀️ Car handed back over the customer ready for its new owner to enjoy this spirited Convertible Coupe and the lovely sunshine we’ve had recently.
