e90 servicing

Hi All,

I'm hoping to get some service advice on my 2006 e90 320d (M47N2 engine).

I'm looking for people's opinion on what future service jobs I should be planning to get done. Plus I'm looking for opinions on the frequency of some of the jobs more regularly required. Here's a list of what I've had done recently;

(Feb 2012 / 100,000km)
Turbo Breather Filter replaced
Brake Fluid Change

(May 2012 / 109,000km)
Swirl Flaps Blanked

(Feb 2013 / 130,000km)
Clutch and Flywheel replaced

(April 2013 / 135,000km)
Air & Fuel Filter replaced
Clean Turbo Breather Filter
Diff Oil Change
Gearbox Oil Change

I'm now changing the oil and oil filter every 15,000km.

I've had it five years now and the car has never given me any major problems and obviously I want to keep it that way. I've never been tempted by any other car and will be keeping this for the foreseeable future so I really want to be sure that I'm getting all the necessary work done and at the correct intervals.

(DSC unit was replaced under goodwill and I'm aware already of a crack in the fuel pipe with diesel leaking in front of the driver side rear wheel when the tank is filled to the brim)

Thanks in advance for all feedback on this.
