Hello! I have a problem with the e39 engine 2.2 ben. Namely, my bunia fires very nicely and works freely. When I want to add gas it goes on 1200ob and it seems to choke and does not get higher. Throttle error came out from under the computer, more precisely: the engine throttle position...

Hi, and which year do you have this e39, because after the engine capacity I deduce that you have an electric throttle?

Hi, 2001 ... so electrically controlled ... I exchanged for another and the same symptoms.

And if you don't get screwed up so it goes out or does it normally go after letting go of the gas? The question is how do the probes behave? Because if it is the fault of the fuel system, e.g. low pressure on the rail, the probes will be very poor.

I work very well on slow ... I press the gas goes to 1200rpm and chokes and waves ... releases the gas pedal goes even on slow And the topic of probes is probably turned off because nothing changes. The LPG oxide in the car may therefore not work

Do you have inpa or dis? To see how they oscillate and do they even oscillate?

I don't have anything special, just general autocom ...

Hmmmmm, it will be hard, because it's best to observe the parameters, e.g. if the resistance on the gas pedal increases smoothly, if the probes react, check if someone in the area has inpa'e and ask to connect the beemka. It will be easiest. Because you know ...

Ok ... something overwhelming ... and I will give a sign what and how

Maybe during the weekend something will come to my mind I will write you something, but we are waiting for diagnostics. If you had m52, I would tell you to check throttles from asc, but you have an electric one, so one has 2 functions .... for curiosity, disassemble the throttle inlet, disconnect the flow, etc., see how you open the throat or open it to the full extent. And if you have it, check the pressure on the injection rail. Have a nice weekend!

Throttle adaptation. Should help.

Hello!
I have a problem with the e39 engine 2.2 ben. Namely, my bunia fires very nicely and works freely. When I want to add gas it goes on 1200ob and it seems to choke and does not get higher.
Throttle error came out from under the computer, more precisely: the engine throttle position controller - slightly blocked and then permanently locked. (Code: A0 and A1?)
Error clearing enters 2 thousand revs and waves but reacts to gas.

Throttles I replaced, cleaned. I also cleaned the crochet by the way. Everything is supported and the problem is the same.
Maybe someone has encountered such a problem and will help

Topic summary

The discussion revolves around a BMW E39 520i with a 2.2L engine experiencing throttle issues, specifically error codes A0 and A1, resulting in the engine being stuck at 1200 RPM. The owner reports that the engine runs well at low speeds but struggles to accelerate, choking when attempting to increase RPM. Various troubleshooting steps have been taken, including replacing and cleaning the throttle, but the problem persists. Participants suggest checking the fuel system for low pressure, observing throttle position parameters, and performing throttle adaptation. A final resolution was found to be a damaged wiring harness at the control computer plug.
