So... I took the 147 to the car dealer to check the selespeed system among the sounds I was hearing around the belt/engine area, tuned out that didn't find anything wrong with the belts and told me that the noise that I hear when downdshifting the gears is normal., but they updated the selespeed, and as soon as I got the car back I discovered a leak from the selespeed reservoir overflow pipe, is this normal after the selespeed update? or should I take it back.
Maybe they replenished the selespeed reservoir while the system was fully pressurised. Keep an eye on the selespeed oil level and see if it drops. If it keeps loosing oil trough the breather pipe, your accumulator is probably shot. When you enter the car in the morning, how many seconds does the hydraulic pump prime?
As far as the Juddering goes when the car is cold, it seems that they don't don't know - they suspect it's from the timing belt been out of time and they say that the engine is running "rich" what ever that means!...
So it means to spend more money and they might fix it or they might not right?
It's not uncommon for the selespeed to be a little juddery when cold for the first km. A calibration with correct clutch push rod adjustment should almost eliminate this problem. Being decisive with throttle also helps. Cleaning the EV0 electrovalve could also make a difference.
If the car is running rich, it's overfueling for some reason. Could be clogged air filter, lambda sensor, maf sensor, cracks in pipes/manifold/exhaust, fuel pressure, canister valve, injectors, timing, blocket cat just to mention some...
