1)The 'check engine oil level' light on
the workshop changed another engine oil level sensor OEM brand HELLA ,channged new engine oil for me "FOC" ,the 'check engine oil level' signal gone,so far so good
2)the asc and abs light on
confirmed is the asc module faulty,because after fix a new module on it, the asc & abs lights go off,so fix a new original bmw cause RM1800
3)when the rpm going down to about 1k rpm my engine shut down with all the light still on(battery still supply in) ,i push gear to N swithoff the engine and swith on again,luckily the engine can restart ,this happen few times since two weeks ago
my car engine not stalling any more since that day incident untill now,so this problem still not solved yet,
thanks bros for all the response and help
