R56 Throttle Problem - dracoola - 06-08-2015 Hi eveyone, My mini has a problem with throttle. I'm getting these errors from ISTA/D : 28A3, 28A5, 2B02, 2B06, 2B0B, 2B22, 2B4D, 2B4E, 2B6D, 2BD3 ISTA screenshot : When i've started car, rpm goes to 2000 and downs again to 800-900 continuously. I fully press to throttle pedal but rpm cannot pass 2000. DME shows throttle pedal position as %99,61 and pedal voltage 1 as 4,00V but pedal voltage 2 shows 0,07 when throttle pedal fully pressed. Is my problem about throttle body or DME unit ? Do you have any idea about this issue ? RE: R56 Throttle Problem - aiauto - 09-08-2015 I suggest you check the oxygen sensor voltage,maybe a ir leak from mainfold R56 Throttle Problem - dracoola - 09-08-2015 No air leak in intake system...

Now finally i've found problem on temperature/pressure sensor on the intake system, which is one placed before throttle body. this sensor has causes short circuit on the dme cy320 power supply on the second voltage monitoring line. because of that my throttle body and other sensors not working properly and my dme throws voltage monitoring errors. I could not find this sensor in my country, because JCW version of this sensor never ordered in turkey. my friend found that on california mini service and he will be here in three days.. I'm happy for found the problem
