It has been mentioned that there may be a possibility somebody could translate this receipt for the works done on my car this year (by the previous owner)

fingers crossed.
**EDIT

have found out Google have a Slovakian keyboard option, very handy!

I managed to translate as this:
Set nozzle carousel
Spring
Washer
Delphi repair kit
check cr injectors for test
repair cr injector Delphi
set of seals
bearings
transport pump
high pressure pump repair
venture tubes

 

The 'carousel' is the fuel rail, the kits are filters and spindles for the existing injectors. It sounds like they replaced the pump, rebuilt the injectors, then re-seated the original injectors.

I would hope that they rebuilt the set, and not just one sticky injector.
