Dear all member fellows, am a new z4 owner which just got my car 2 months ago. Need some guidance from all members here. As according to my mileage reader it shows my car run 32k km when I got my car ( reckon uk spec 2010). It is come together with opal 12 months warranty of which my car must send to particular authorize workshop. My problem is the idrive shows that my next service is another 26k km, break pad 76k km and next service is in 2016. I think it is ridiculous with such reading. Upon am asked the salesman he told me is a technical issue as in uk reading unit is miles and now converted to km. To me is totally lame excuse. My question now are: 1) Why there is no ATF to be replace indication2) I believe all the computer reading been modify by the car trader prior I got the car, if so is there anyway to trace back the actual mileage reading to my continuous maintainence follow up? 3) Am not comfortable to the opal authorize workshop, as those seem like smaller scale workshop and worst still the engine oil they offer not as per the BMW manual book ( gastrol, shell and etc) 4) anyway can recommend me a reliable opal authorize workshop as I have no chooise to send back my car to opal authorize workshop for at least 1 year maintenance or 25km (whichever come first) in order not to void my warranty period. Thanks in advance for your kind assist and suggestion. Hope have a chance to meet up all the BMW fans here for TTThanks
