Jeg vil skrive på engelsk nedenfor pga. min dårlig norsk. Høpper det er greit med dere
So last summer bought my first car (BMW e87 116i, pretty basic equipment) here, presented as fail free which turn out to be major p.i.t.a.
At a time i didn't bothered with air-con (this is just one thing that is bad with car) it was hot and blower worked, so i suggested that everything was ok. And usually i like to drive with window little open than with air-con.
Problem started when started to getting colder and colder, hot air would blow only from windshield defrost. Could not change direction of air blowing nor trigger seat heating.
So i bought cable and downloaded reinghold ista to start troubleshooting.
Got few error:
009C48 - IHKR: Mixing-flap motor
009C4A - IHKR: Fresh-air/recirculated-air-flap motor
009C4D - IHKR: Air-distribution-flap motor
00A6CF - JBE: AUC sensor
00A6D1 - JBE: Auxiliary-water pump
Things that i done:
First tried to delete errors, with no success. Error just pop back,
Control panel responded to ISTA functions (turn all lights, can read potentiometer angle, ...), checked that out
flaps stuck at 255%
Checked all fuses, all good,
Battery was around 12.4V, so i checked that out
According to newtis.info documentation flap motors are connected in line so if first motor fail rest wont work. So i put 2nd and 3rd in place of first flap motor. No good
Checked all cables for open circuit or high resistance, all looks good
Bought new fsu, no changes,
Bought used klima control panel, no changes
I have run out of ideas what to look. All i suspect is that i bought broken panel or it ghost possesed
Anyone with ideas what to look, or someone lives near Kristiansand that don't mind trying klima panel from his car just for check
Takk
