ASC+ABS+Brake warning lights AND other "Activation, Solenoid, Fuel" errors! HELP!!

Hello from Brazil!


Before explaining all these thinks below I have already searched on this forum for my problem and could not found a solution or same problematic as I’m experiencing and I think it should help someone if we discuss and find a solution.

I’m almost giving up of my car, but I think someone here could help me.


Information of the car:

- BMW 323i automatic steptronic transmission (Euro spec)
- I have already replaced many parts and sensors already (before buying the scanner)
- Car has already done the vanos fix
- Already changed MAF sensor
- I already all sort of problems with the car, mainly about suspension because roads in Brazil are not good and the car is armored so it is 200kg heavier.
- The car is running great on take-offs
- Front brake sensor was recently changed. (left front wheel).. The one from the right rear wheel seemed to be ok, and I don’t got any error concerning this sensor.
- I have BMW Scanner (1.4.0) and below are the errors I got so far.

Errors scanned:


DME -> Shadow-memory:
32/14 - Activation, solenoid valve, fuel-circuit changeover
85/08 - Signal, CAN ASC 3
23/12 - Activation, relay, secondary-air pump
3E/12 - Activation, solenoid valve, secondary air
7E/12 - Activation, solenoid valve, tank-leak diagnosis pump
7F/02 - Activation, solenoid valve, suction-jet pump
34/02 - Activation, solenoid valve, exhaust flap

(errors P1453 P0412 P1470 P1145)

IKE -> BF/C8 - Internal fault, EEPROM checksum, coding incorrect/incomplete

1rst problem

asc + abs + brake warning lights . It is a Random problem.

2nd problem

Sometimes the car shuts down at random speeds after is on for 30-40 minutes. It happens usually when it is already hot. It kind of stall, shuts off and right away on very fast.

The exterior temperature goes up very very fast after the car is hot after 30-40 minutes, and it increases even more if I turn on the Air Conditioning. And after all this it causes that stall thing and can even shut down the car for a while. But the engine temperature stays normal all the time.

After getting the car hot I have tested the auxiliar fan and it is working perfectly as it turns on normally right after I turn on the A/C. So I think the car is not actually getting hot and maybe it is just the exterior temp sensor that is crazy. (I already bought a new one and Im about to put it on the car).


3rd problem

My old mechanic, the one that I stop taking the car because I think he was a liar, after all the parts that he make me buy and spend on the car told me that the problem should be Throttle body. Does anyone know that this could really be it considering the errors I got?

He already cleaned the Throttle body on the car, but he said that it could be an interior computer fault of the part.


4th problem

After I received my BMW scanner I was trying everything I could do with it, and I went to the IKE and tried to reset oil service and was not able to do it. So I have changed the parameters of days of service, and now I could not even reset with the oil service reset tool and got that - X KM remaining for service. When I reset with the normal oil/inspection reset tool I got on the cluster a 0 KM blinking when I turn on the car! Does anyone that has the BMW Scanner tool could help me telling me what the original parameters are as described on the print screen attached?


Parts that I bought and still did not put on the car until now:

1. Exterior temp sensor (I think it should be faulty or the cable)
2. Throtle body sensor (I bought one used and in good conditions on ebay).
3. ABS Speed sensor. (But Im not considering to put on the car since it does not show error related to it)


My own conclusions:

1. Im not sure if the ASC error and abs + asc + brake warning lights have anything to do with the stall problem.
2. Maybe the car is not actually getting hot and the problem is the exterior temperature sensor that is faulty.
3. Maybe the exterior temperature cable is plugged to the engine temperature sensor (thermostat) and it the engine is actually getting hot.
4. About that solenoid error I don’t have any clue of what could be. I have already checked all the relays and fuses and it is everything ok. And the car probably would not be working correct if anything at the fuel system was faulty right?

Please help!

Dude i had that same problem, did you try taking out all the air in your radiator sometimes their is air trap inside the engine. Run your water hose to your radiator and take the presure valve off fill it with water, Their should be only water comming out from the presure valve. Turn on car and turn the heater on, Something like that. Good luck.
