I'm guessing you are refering to the softer steering wheel from the later buses.
After I fitted mine, I had the same problem but with regular use it has stopped mucking up my hands. It was a real problem as I had to wash my hands after every drive.
And I am not going anywhere near the double entendres!
One I thing I can't resist though is;
if it is playing up in the sun of your side of the blue ball, the steering wheel must be seriously unwell.
