Long story short I bought a non running 2007 plate alhambra tdi with the 2L tdi lump. It had the low oil pressure problem due to a worn key. Anyway I managed to find a good company called kmb parts, after a bit of googling it seemed they were the place to go to. I bought the replacement shaft with new 100mm key and the tool for locking the shafts to get them aligned properly.
Took a few hours but got it together, oiled filled and fired it up for the first time, ran like a dream.
Anyway I thought I'd add some pics
The car
The damaged key
Balance shaft unit which sits in the sump, new balance shaft and longer key
Shafts in place with shaft locking tool fitted
