STEERING COLUMN

[scorpionfrance2]

Hi All
Just returned to the Forum after a bit of a break.
Sorry if this has been covered before, but, my probelm is this...
I have a 2.5i Z4 registered Dec 2006, which has been, almost, faultless in the six years I have owned it - until now! It has developed 'sticky steering syndrome' over the last few weeks - intermitently notchy and not pleasant to drive. I was under the impression that the problem was solved for 2006 cars and later, but that's obviously not the case.
I've seen posts suggesting drilling and lubricating the column, but I would prefer to replace it. Being an OAP, I really can't run to main dealer prices, and will probably have to do the work myself. Which brings me to my question can any year of Z4 columns be used as a replacement?
Cheers
Scorp.
