Problem with black smoke and loss of power in BMW X1 successfully resolved with lambda sensor repair

Hello, I have problems with my lambda sensors bank1 sensor 1 heater circuit interruption and bank2 sensor 1 signal too slow. Check engine light is on and comes on again after clearing but no smoke or loss of power. Vehicle is an Audi A8 D3/4E year 2003 engine is a 3.7 gasoline engine

Hello, The error codes you're seeing suggest that there might be an issue with the heater circuit of the lambda sensor in bank 1 and the signal of the sensor in bank 2. This could be due to a faulty sensor, wiring issues, or a problem with the engine control module. I would recommend checking the wiring and connectors for any signs of damage or corrosion. If the wiring and connectors look good, you might need to replace the lambda sensors. If the problem persists after replacing the sensors, it would be best to have a professional mechanic inspect the engine control module.

The adapter shows me : DME : Crankshaft ; Exhaust camshaft , Reference; I got this error once, otherwise never again 👀.... (Here a year ago) With regard to an error message in the car , on closer inspection , ehr probably says ,, magnetvenile 👀 can that really be because of it !

Hello Sebastian, The error code you're seeing is likely related to the crankshaft position sensor or the camshaft position sensor. These sensors play a crucial role in engine timing. If they're malfunctioning, it can cause a variety of issues, including poor engine performance and even engine stalling. I would recommend having these sensors checked by a professional mechanic. If the sensors are found to be faulty, they will need to be replaced.

I have a warning saying "Engine fault! Reduced power". When I ran the scan through Carly, I get the following error code. 002A99: DME: Crankshaft - Exhaust camshaft, reference And the freeze frame data as follows. Motorvarvtal: 768 rpm motorstatus: 2 0-n (Motor) -Oeltemperatur: 88 °C Spänning kl. 87:12 V Car details. Bmw 520i 2008. N43B20 engine. I recently replace both camshaft position sensors because they were faulty.

Hello, The error code you're seeing is related to the correlation between the crankshaft and exhaust camshaft. This could be due to a timing issue, a faulty crankshaft position sensor, or a problem with the variable valve timing system. Since you've recently replaced the camshaft position sensors, I would recommend checking the timing and the crankshaft position sensor next. If these checks don't reveal any issues, it would be best to have a professional mechanic inspect the variable valve timing system.

I have deleted the error and will check again after a few days. Kind regards M. Schmidt

BMW F48 X1 Xdrive with B47 2.0 diesel. Fault code was 284E00 - this was removed by replacing the front oxygen/lambda sensor.

Hello Philip, That's great to hear! Replacing the front oxygen/lambda sensor is indeed the correct fix for the 284E00 fault code. Please continue to monitor your vehicle and don't hesitate to reach out if you encounter any other issues. Safe driving!
