Hi Blackmsport,
Have you been able to have a good look around your (clean first) engine and other areas.
When was your last Service.
Have you phoned or taken to the dealer and asked them.
You would be close to running out of Warranty or have you already run out.
On a different note, a 6 cylinder X1 in Aust. isn't that common. If your into Modifications, the USA People on these threads are doing some
ones.
