hi guys, i bought a clk 320 around a month ago and im really happy with it just got 2 questions..1 it has a auto/tip box with a w/s setting, should i be in w or s for normal driving??? i always thought that w = winter s = sport but according to my handbook s= standard so which will be the best for mpg? 2 the only thing that dosent work is the multi-function steering wheel, if i pull the lever nothing happens, i did notice on the service history that it had a new indicator stalk due to a fault so would it be possible that they didnt connect the multi-function steering lever up correctly when fitting the indicator stalk?? also is this a diy job to fix??? many thanks spencer
