I love my facelift 3.0d!
Awesome power, torque, economy, comfort, handling and looks.

Only a couple of things have bugged me so far: the air filter and fuel filter.

Changing the air filter is an absolute bugger of a job!
I've done it 3 times, the first time took the good part of an hour and now even though I know what I'm doing, it still takes nearly half an hour.
You have to remove the cabin filter housing and covers, engine cover, air intake, air filter cover that has a hidden bolt that has to be done by feel with a uni-joint socket on an extension bar,
and then the cover has to be rotated in a space where it just doesn't fit to get it out! Come on!
Getting this cover back on is even worse, I've actually put a hole in a new air filter once trying to get it back in place! What were they thinking!?

The fuel filter is also a right pain in the arse!
Under the car, under a huge cover with lots of bolts some requiring two socket extensions to reach.
On a diesel where it is best to change filters quite often, this is just a pain.
What makes it even worse is that the pre-facelift cars had a normal diesel bowl type of filter in the engine bay, a minute job to change.
