Hi folks , this is all new to me so bear with me!! Owned my Q5 for 9 months and love the car. Great to drive and look at and it has a quality feel. It is a 2010 black s line sp ed tdi. Booked it in for emissions update and got a brand new A4 white s line 2.0 tfsi courtesy car NICE. Upon return I got a goodwill Audi car care pack.VERY NICE. HOWEVER,the car doesn't feel the same to me. It feels a little sluggish and every time I drive off in first there is a judder through the clutch pedal. I drove home 25 miles and the mpg is down a bit. Early days I know but I think I will be going back in time to get the car checked over. Anyone else had the emissions update and had any problems?? Cheers .
