After that take remove the large C clip which holds the CP to the throttle body and then undo the jubilee on the intercooler side. Don't lose the C clip as it can't be bought from BMW on its own. Next is the torx bolt near the middle of the charge pipe which holds it in place. The MAP sensor will still be connected at this point, it is a bit fiddly to remove but a thin screwdriver and a bit of patience will allow you to remove the wiring loom. You might be able to wiggle the CP out and twist it and then remove the wiring but you don't want to stretch the cables.
Space isn't so bad on that side, trying to do anything on the turbo/steering column side is a complete pisstake. I have big hands and need to change the engine mount which looks to be impossible
1/2 a days work then idnan ? Will wait for the weather to improve a bit first, may sell the 335 and buy a boat
