Hi Guys,

i thought I would post this as a heads up, found oil in all 4 of my cam shaft sensor plugs, I did have an engine light come and pulled the codes and sure enough exhaust camshaft bank1 and intake camshaft 1 sensors showed a malfunction.

So I decided to replace all 4 sensors as the newer version of these sensors address the issue of oil leaking through, onto the harness and then working its way to the ecu, which could be very pricey as a few M!57 engine owners have found out!

Super easy, took me 15 mins to swap over all 4 sensors, only to realise that I had run out of electrical cleaner so I’ll finish her off tomorrow.
