If the above-mentioned error is identified, one possible cause may be a faulty signal evaluation in the engine control unit.
In order to exclude any other sources of interference, first of all a check should be carried out on the periphery (power supply, engine oil level, sensor, etc.)
If then no errors are found and all the measured values correspond to the specifications, a software update of the engine control unit is required.
The update can be carried out, for example, via macsRemote Services or with a pass-thru-capable diagnostic device of the Mega Macs series and
registered access to the vehicle manufacturer's online portal.
If no appropriate equipment is available, please contact an authorised workshop.
