The issue I'm having with the car, is, when idling upon initial cold start up the engine knocks, which appears to be coming from the bottom end (So I'm assuming low oil pressure related issues =/ ) once the car is up to temp the knocking is gone, but when in the car initally, vibrations can be felt through the cabin. I'm unsure what issue this relates to exactly, as there doesnt appear to be any loss in performance or power at the moment, but I know obviously that this issue needs to be corrected as it will probably cause long term damage. The car is going in for full service saturday but I have little faith that a service will correct the knocking issue. I'm thinking dodgy oil pump or along those lines.
Any advice would be much appreciated.
