Hello. I've found many good information on this board, so decided to share with some info that could be useful.
Last week I'd decided to have my high pressure fuel pump reconditioned as it was bleeding through the top seals and the mechanic told me that it can be a reason of difficult morning start.
I'd found the info about taking off the HPFP without removing the cambelt. All you need is to use two 6mm screws to fix the pulley.
The holes with thread are used to take the pulley off (photo #2)
And the other two are for fixing the pulley to loose it or to tight it up(photo #3)
You should use these. Just be careful with the Nm (not too strong).
When you fix the pulley, loose the pulley nut, the HPFP nuts (3) ant take it off.
Then you need to brake the HPFP. It's not very difficult, however there are tiny parts, so you have to be careful and watch your movements in case not to get lost any of them ant to put everything together in right order later.
Here's the scheme (thanks for the shop manager or printing

The oil-seal is old separately, so if you haven't got it - it's not worth to go on with two big o-rings in front of the pump, cause you probably won't be able to put the oil-seal back unbroken (when taking it off).
So, change the 0-rings, seals, put everything together and return pump to its place. I think you should loose the pulley fixing bolts to get the pulley centered after inserting the pump (as I didn't do and now the pulley has a slight side moving).
The recondition kit for fuel pressure sensor is sold separately (in LTU, don't know about UK) (2 o-rings and seal).
I've paid for the parts (at the BOSCH dealer in LTU) 15£ (main kit) + 2,5£ (pressure sensor kit) + 9£ (BOSCH fuel filter). The job took about 3hrs.
