I seem to have suffered the same mystery oil leak as Indian Bob tonight, Small droplets on the drivers screen and cowl which started to appear whilst on the Motorway to Blackpool Illuminations.
This is where I also got my first taste of the engine running in 'skip mode'. Although it was a fun new experience driving the M3W through the lights I was glad to escape the crawl and get some cool air flowing past the engine.

Had a look at the engine and suspension when I arrived home and it looked more likely to grease originating from a top suspension bush rather than oil from the engine. Will have a closer look tomorrow.

Still running in (now at 750miles), but I think the ECU has just released a few more RPM joy
