The engine oil level is not shown in BMW F01 2010, the message is:
"Measurement inactive. Service interval adjusted. Have the system checked at the next oil change."

Can the engine oil level be checked in ISTA? And how?
I cannot find it...

Thanks!

This error is shown when the oil-level-sensor is defective! Maybe also only the wiring between the sensor and the ECU.
If the sensor doesen´t give any plausible signal to ECU, then you can´t reset the Oil-Service, because die DME doesen´t know anything about the OIlquality.

Replace the Sensor or check the wiring and everything´s gonna be allright.

Thanks,
BMW Dealer told DME malfunction (replace DME).
So I was wondering, if the sensor is maybe ok, then the oil level can be read in ISTA.
Can it be read in ISTA?

Dealer tell´s you always the most expensive I would check the Sensor by myself and don´t trust everybody. Cause in most cases there is only a wiring problem!

You can´t read it with ISTA, cause the sensor is connected to DME.
So if you read out DME and
1.)the DME is faulty--> you won´t see anything.
2.)The sensor is defective--> you won´t see anything.

You can´t connect direcly with the sensor.

Fault codes??? If you have a BSD signal failure you also can't read oil level... I had it twice that the alternator was defective... But that was with a N63 Engine...

It is possible that the BSD line is defective on ECU. This seems to be a common problem when alternator is defective.

Measure the BSD voltage to ground, with alternator disconnected. The voltage should hover around 7 volts. If you disconnect BSD wire from ECU it should hover around 10v if you measure the BSD pin on the ECU. If the voltage on ECU goes to 13v or sits at 0v, the BSD line in ECU is defective.

Inside the ECU, BSD is managed by either an Infineon or Bosch ASIC. These are hard to find, so I strip these out of faulty ECU. I'm looking for a source for these as they different for each ECU.

Anyway, I've fixed a few ECU like this.

If you have ISTA then read the codes and test the sensor using the test plans?

F01with n63 engine, sometime defect BSD data bus on DME, it has Puma, replace DME is fixed fault.

Try to update with Ista-p.
