Get the air flow meter checked.

Sorry no got.

the gearbox ecu has spotted and logged a problem. you can either try a ecu reset or get diagnostics done.

this is the check engine light does it come on then off? did it stay on? if this light is comming on any one of a hundred or more thing can cause it. from a loose gas cap to a sticking sensor. you might want to have it hooked to a computer to see what is causing it might be a minor problem like low washer fluid and it could be the start of a serious one. these lights remind you of scheduled maintinance,low fluids,oil changes ect depending on the manufacturer standards.i would check all of the fluids and if they are ok then get it checked better to be safe than sorry

sounds like a blown head gasket

if the transmission was low on fluid you may have worn some parts,take this to a shop that specializes in BMW transmissions,this is not for the local transmission guy,special tools needed to test the transmission,may have to be re-programed

Hi joserosa if this is a manual gearbox you just have to grip the gear knob and pull upwards until the gear knob is removed, the same principle is applied for a auto box but hold in the release button while removing, regards Mark.

You have a bad gearbox position sensor located on the transmission. When the transmission computer sees the fault in that sensor it goes into a protective mode in your car starts out in second gear that's why it is sluggish. This is a very common failure on that car. The heater issue is not related.

try disconnecting the air mass meter sensor if it runs better then ur air mass meter has failed had the same problem
