Click on the automatic vehicle model selection option. Click on the diagnostic option. Select the control unit option. Click on TP position check. Click OK to start the automatic reset programming. At this point, run the engine, the idle system works normally, and the throttle can be used normally.
When my BMW X1 had intake valve carbon buildup issues, I first used walnut shell blasting to physically clean the carbon deposits. This step was crucial because excessive carbon buildup can cause engine knocking and a significant increase in fuel consumption. After cleaning, the ECU might not adapt to the new condition immediately, leading to engine shaking or rough acceleration, so reprogramming is essential. Connect an OBD scanner to the vehicle's computer, such as the BMW ISTA diagnostic tool or mobile apps like BimmerLink, and locate the engine control unit to perform a learning values reset. During the operation, simply select the adaptive learning or reset function option; avoid modifying other settings randomly to prevent fault codes. The entire process took me over an hour, and I recommend beginners watch tutorial videos beforehand. Tools can be rented from e-commerce platforms. For prevention, I regularly drive at high speeds and use fuel additives to reduce carbon buildup. After reprogramming, the engine response improved noticeably, but this is just the beginning—don't overlook routine maintenance.
My experience with programming after cleaning carbon deposits on the BMW X1 intake valves is to first ensure the intake valves are thoroughly cleaned—just spray some chemical cleaner. For the programming part, I use third-party diagnostic tools like Carly for BMW, plug it into the OBD port, connect via Bluetooth to my phone, and select the reset option. It was easy to handle, and after the ECU relearned, the car drove much smoother. However, carbon buildup often occurs due to frequent short-distance driving, and city traffic congestion can easily cause it to recur. Programming only adjusts the computer's adaptability, so don’t expect a permanent fix. I recommend buying tools for DIY—it saves money and is convenient. You can get a set online for a few hundred bucks, avoiding frequent expensive trips to the dealership. Afterward, using high-quality gasoline and adding some cleaning additives can help protect the engine and extend its lifespan.
