Thanks Bro B33mEr and clavenk for your advise.
I test drive again today. Here's some of the problems noticed:
1) Driver side window got scretching sounds when down/up. Salesmen kauntim can fix this.
A common problem with E46 window regulator ... I'm on my 3rd window regulator
2) When accelerate >120km/h steering feels minor vibration. ON WHEEL balancing problem lor.Mechanic advise to change for 17" rims for better handling.Also this can kautim to fix by the salesmen
Check the front control arms bushings for wear in fact check all the bushing.
3) Steering pedal shift not working when change gear. But changing gear using gear knob seems fine. Salesmen said this could be some sensor problem. He promised to fix it. Sweet talker guy haha
The paddle shift will cost you RM800 new from BMW dealership ... Actually if you open the paddle shifter and spray contact cleaner on it should work again ... but don't tell the salesman :4:
4) Test drive to check the gear problem by mechanic seems ok when use manual mode. C or comfort mode seems got clunking sounds but according to the mech this is normal for SMG especially if you do not familiar how to use this tranny.- I do surf other forum especially from US,they also mentioned the same.
Yes it's the nature of the beast. Do check for hydraulic leakage when hoisting the car up
However,engine seems smooth and quiet. Exterior and interior finishing satisfied. Body color still original in phoenix yellow.18" rims/absorber still in good condition;quite comfort even you drive thru bumpy road.
Other sifus who have currently own SMG or have experienced before using SMG,really appreciate your advise.
