Hi guys...Lots of worrying yet interesting issues i find out about the E46 from this forum...I am considering buying over my brother's CKD BMW E46 328 year 2000 and i will still have time to think and consider till next week before he dispose it to the used car.I have driven the CKDs E46 318 1.9 and 328, and i got say i do like the E46 328 alot as it has sufficient power for road use and yet handles pretty well for a stock car and comfy and has 4 doors. But what i read about the E46 gearbox is scary. http://www.bmwclubmalaysia.com/forums/inde...?showtopic=9440http://www.bmwclubmalaysia.com/forums/inde...?showtopic=4206My brother's E46 328 is on its 6th year and the car has cover 90+k km. After the warranty period, all my brother did was just normal engine oil + filter change every 10k - 15k km.He has not done any transmission or rear diff oil change!!! This worry really worries me as i do not want to be stranded with a RM10k overhaul on these boxes... h34r: And what is expansion tank that i notice alot of members are changing??And what are the possible things that need to be changed as a preventive measure for a car approaching the 100k km mileage??Thanks for the advice guys!! :yes:
