Problems with 2014 BMW 4 Series gasoline engine: engine light, rough running, high consumption - throttle valve defective?

Hey guys, I've got a problem with my 2014 petrol BMW 4 Series. The car is behaving really strangely - engine light comes on, engine just cuts out, doesn't really pick up the throttle, runs erratically, pulls when accelerating and consumes a lot of fuel. I think it could be the throttle valve, but I'm not sure. Do any of you have experience with this kind of problem and could give me a tip on what I should have checked at the garage? I would be interested to know how you have solved this and what your experiences are. Many thanks in advance!

Summary of the thread

The conversation revolves around a problem with a 2014 BMW 4 Series gasoline engine, which includes the engine light turning on, rough running, high fuel consumption, and potential throttle valve defect. The car owner suspects the throttle valve might be the issue. Another participant suggests that the problem could be with the accelerator pedal module, based on their experience with a similar issue. They recommend having the vehicle's error messages read out at a garage. The car owner agrees to take the car to a garage for a fault diagnosis. Other participants suggest checking the throttle valve for oil, as a malfunction of the crankshaft ventilation could be causing oil to leak into the throttle valve.

Hello, I recently had a similar problem with my 2012 BMW 3 Series. I'm more of a layman, so I have little experience in the automotive sector. I took my car to the garage and it turned out that the accelerator pedal module was defective. The repair cost 205 euros. Of course, it could be something else in your case. I would therefore recommend that you first have the error messages in your vehicle read out. Could you perhaps share a few more details about your vehicle? Then I might be able to help you better.

Hey, thanks for the tip! Did you get the same error message with your BMW? I thought it was due to the throttle valve, but your experience with the accelerator pedal module makes me doubt it. I'm a bit worried about the increased fuel consumption and want to solve the problem as soon as possible. I recently had my BMW checked in the workshop at 218784 km. I'm assuming that's a detail you wanted to know, right?

Hey, yes, my 3 Series also had an error message like that. If your 4-series already has almost 220,000 km on the clock, it can have the potential for all kinds of problems, including a problematic accelerator pedal module. But you really shouldn't rely on my amateurish assessment. The throttle valve could also be the cause, as it can also break down at this mileage. Your symptoms could certainly be the same. You should definitely keep a close eye on the fuel consumption. Poorer fuel consumption can indicate several problems, including a defective accelerator pedal module or a defective throttle valve, but also other things. That's why my recommendation would really be to visit the garage and have a fault diagnosis carried out. The exact mileage reached during the last inspection is less important here - it is more important that you recognize the problem early and solve it to avoid major damage and additional costs. It's best to make an appointment as soon as possible! I think it's great that you're being so careful with your BMW. Please keep us up to date!

Yes, you're absolutely right. I will definitely make an appointment at the garage as soon as possible and find out the exact cause. Your input was really helpful and I now have a better idea of what to expect. Yes, the fuel consumption is actually something that worries me. I will definitely keep a close eye on the fuel consumption, as you recommended. I will of course report back on the results. Thanks again for your help and advice. Have a great day!

Hello, SUPER that you are taking part in this conversation. So that we can help you as efficiently as possible, it would be great if you could give us a few more details about your vehicle. Which vehicle do you drive exactly? How does the fault manifest itself in your case and have repairs already been carried out? I look forward to your reply

Hello everyone, I drive an E91 320D Touring built in 2007 and have the error message throttle valve, control. I've now got a new throttle valve from Pierburg but haven't installed it yet as I'm not sure whether it needs to be programmed or not. If so, does it work with carly? It's an M47D20. engine. LG Andi

According to BMW, it is not necessary to program the throttle valve in your particular case. Nevertheless, you can of course delete the adaptation values with Carly, but as I said, this is not absolutely necessary. This is because the throttle valve in your diesel does not work in the same way as in a petrol engine or has a different function. In your vehicle, the throttle valve is necessary for DPF regeneration in order to limit the air mass.
