Bro,
actually i never own a BMW and study about it b4 i bot this car. i get it from a used car seller. i did test drive the car but the trouble din float up when i test it coz i just try it for a short journey. until now i oso cant believe that why i din send the BMW specialist to diagnostic the car b4 i buy it, i'm yet stupid enuf. after i draw back and i drive it for few days, the troubles i mentioned all came out (engine vibrate; low power when the rpm below 2k and huge petrol consumption). i took almost 6 weeks to repair it at the BMW specialist which recommended by this forum, but now still kenot settle my troubles. the mechanic told me that since we hv did the top engine overhaul, the coding of the driving usage memory in the mainboard b4 all cleared, it needs times to tune back after we drive for few journey, i oso dunno is tat right or not. By the way, i bot this car at RM90k - 318i 2.0L Valtronic 2002/2006, is tat cheap? at this stage i ade dunno which way to go and wat to do, js wish tat i may settle my troubles and ride on a great BMW as wat i aspected b4 like u all, tats why i need advices from you all pro's here. anyway, ur's car is auto bavaria one or imported one? any ideal to share with me abt BMW which we need to know? ur opinions are mostly appreciated!
