Since 1 or 2 mths ago, my e90 have gearbox issue whenever i park my car more then 5hrs. 1st gear will hesitate to change to gear 2 and if u carry on depress the accelerator after 2.5k RPM, ccid 246 fault will show. Off engine n start again, fault will go off.. slowly drive, ard 2km plus and once car hot enough it will be ok for the rest of the journey... but as long as car park above 5 hrs.. problem will resurface. Yesterday after car park for 10hrs, i warm up n drove.. first 200m, ccid 246 shown and stuck there.. now car cant travel above 40km per hr. Any 1 such problem before.. please share n advice.
