D4 Servicing requirements

[Defenderbuff]

Hi all D4 owners,
Im after the pearls of your wisdom in advising a scheduling task regime for a D4 that has completed 178,000km

I have purchase at 162,000 and the D4 had been serviced by a Gippsland landrover Dealer since new.
The compressor for air suspension was replaced and upgraded.
Servicing every 15,000km or thereabouts.
I had the auto serviced when purchased and replaced the plastic pan with the metal one, new oil and filters. The auto was described as being in good health!

Moving forward I plan to change oil every 10,000 km.

Current concerns are when to do,

Timing belt.
Hi pressure fuel pump belt
Electric park Brake

Any further planned maintenance suggestions will be greatly appreciated. I want to get 300,000- 400,000 from my D4 to equal my other vehicle( 2007 Jeep Grand Cherokee 3.0l V6 Diesel - 300,000km currently.

Thanks in advanced for all replys

Timing belt. Now.
Hi pressure fuel pump belt. Now.
Electric park Brake. Now and check every service. If it's not making a noise, then it has been well serviced, so all you need to do now is check it. Straightforward and costs nothing.
