Reduced power, showing yellow half engine light on rev meter dash and after an OBD scan, i got P1637 and P2103 error codes. Check engine light on the dash is lit but the misfires and limp mode driving feeling has gone. What could it be?
You can look them up right here at Motoring Alliance. ECU Codes Chart - 2nd Generation MINI - Library Maybe something wrong with the throttle positioning motor.
So, you have throttle errors and fuel rail pressure error. Sounds like that is where you should look. Could be as simple as a clogged injector. Had that on my kids CRV. Stuttering. Can't keep it running. In the end it was a fuel injector.
My main concern is, how should the technician begin to diagnose correctly, because most just have the tendency to start changing stuff. But this method -to change stuff until the problem stops- can mean a lot of wasted money!
If you are worried that you shop are parts changers I would take it somewhere els. Are you close to any of ower sponsor?
Where i come from, ive been to many mini shops but i haven't met one, not one that really know the whereabouts of the mini, or should i say the whereabouts of the engine and its function!
I just replaced the HighPressureFuelPump but the Throttle valve errors (1637, 1638) are still there. If its the Throttle valve, maybe i need to fix it, maybe clean it someway. has anyone got an idea on how to do this?
Well since you won't tell us where you are located and you don't want to spend any money you probably use cheap gas and change your oil every 15 thousand miles. So your car needs to be maintained. Change the oil, run top tier 93 octane fuel, try some fuel injector cleaner, and get the carbon blasted from your car. Get you car scanned for codes and reset the adaptive's. You have to spend some money to keep things in good running condition. If you cannot do basic maintenance for a car a MINI is not for you. Maybe you should look into a Toyota or Honda.
Because they have nothing to do with each other. You didn't want to take it to a mechanic that would just throw parts at it.... Yet that is exactly what you just did.
