Change the thermostat in it.

You have a check light on !! Surely you know that you have to check for codes, to even get pointed in some directionYou don't ever drive more than one day without checking for codes & if you can't have the car completelyrepaired in a week, you don't use it until you can.

HelloWhen the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Had same problem on my 120i (2005 reg) only done 16k. Took it to official dealer and they said it seems to be affecting 04-06 models. BMW agreed to pay for part and half the labour without any pushing - the dealer contacted BMW on my behalf before they even confirmed what the problem was to me.

dtc relates to brake hydraulic pump unit 1300 top buy from bmw, the rest will be labour.

Had DTC warning light come on on my 120i (2005 reg). Without prompting dealer contacted BMW who agreed to pay for part and half the labour as it seems to be a common problem for 04-06 models.

Hi Nicco, Take the vehicle to a workshop where it can be scanned. The code can be deleted via the scanner. Regards John

Check the bonnet pin (small switch that is pushed in and out by the bonnet opening and closing) which tells the computer if the bonnet is open or close, maybe its faulty or broken and the computer thinks the open is always open even though its closed.

When they are set to the proper pressure, and driven around 40-60 miles, the light will go away. There is the rare case that one is broken, or the sensors lost the code and would have to be re-initialized at the dealership... but that is typically a free service. Goodluck
