A quick update from M Coding Workshop:
We’ll be closed from 2nd–13th October, and will be back to responding to calls and messages from 14th October.

I also realise it’s been a little while since I’ve updated the page! The workshop has been extremely busy, which is a good thing, but it hasn’t left much time for keeping up with posts. 😅

There are, however, some really nice projects we’ve been working on that I’m looking forward to sharing with you soon.

Thanks as always for your continued support and understanding! 🙏

The S63 is a phenomenal performance engine, but like many high-output BMW V8s, connecting rod bearing wear is something owners should be aware of as mileage increases.

Preventative maintenance remains the key to avoiding much more costly repairs down the line.

This 2016 M5 came in for a preventative connecting rod bearing service, so it was time to get the subframe down and carry out the following:

✅ ACL Race connecting rod bearing set
✅ Genuine BMW connecting rod bolts
✅ Genuine BMW gaskets, O-rings and hardware throughout
✅ Thorough inspection and measurement of all bearing journals and clearances
✅ Meticulous cleaning of all mating surfaces and components
✅ ROWE 5W50 engine oil (customer's choice)
✅ Liqui Moly Cera Tec engine protection treatment

As you can see from the photos, the original bearings were showing the expected signs of wear for the mileage and usage of the vehicle. While no immediate failure was present, replacing them now provides valuable peace of mind and helps safeguard the engine for many more miles of enjoyment.

All components were carefully inspected during disassembly, bearing clearances verified during installation, and every fastener torqued to BMW specification.

Another S63 protected and ready for many more kilometres

We get a ton of queries about Android Auto in G-Series BMWs with NBT EVO.

While it’s not natively supported, it can be achieved using an aftermarket MMI box.

You can find compatible MMI boxes here: https://m-coding.ie/products/carplay-android-auto-retrofit

If you’re unsure which option suits your car, or which idrive system you have we have a blog post on that too :

Let's talk connecting rod bearings on S55 engines
Conrod bearing failure is definitely less common than on the N55, largely due to improved oil pickup and bearing clearances. That said, rod bearings on the S55 are not completely immune to wear, especially on higher mileage engines, aggressively driven cars, or vehicles that see frequent high RPM use, track time, or extended oil change intervals.
Key here is monitoring oil condition, listening for unusual bottom end noise, and considering preventative maintenance

This 145k km example came in for conrod bearings due to glittery oil in the filter housing which was well spotted by the owner.

So off with the subframe to do the following:
✅Mahle Motorsport bearing set
✅Genuine conrod, oil pump and sump bolts
✅Genuine Sump gasket
✅Genuine Breather pipe
✅Sacrificial oil and Liqui Moly engine flush
✅Liqui Moly Molygen engine oil
✅Genuine rear differential fluid
✅iStep update
And to top it all off
✅GTS software flash.

As you can see in photos, while all conrod bearings were showing signs of wear, cylinder 5 bearing had considerably more worn upper and lower conrod bearings. We suspect excess silicone to be the cause from a previous attempt at oil pan sealing by another garage.

All bearing clearances were plasti-gauged for peace of mind.
Meticulous cleaning of all components, all torqued to spec.
