Hello!

Does anyone know how to decode the value in byte 7 of a message with ID 35B?

My readings are between 140 and 250, but those values can't possibly be liters per kilometer or liters per hour.

It's a Volkswagen Golf V diesel manufactured in 2007 with an engine power of 66 kW.

Sure, here's the translation:

'Best regards,' or 'Sincerely,' (depending on the context).

Michi.

Use only the lower 7 bits; bit 8 is an overflow indicator, meaning the value has exceeded its maximum limit at least once since the motor started.
The multiplier is 256 µl (the 7 bits here are actually only the most significant bit of the value, but the least significant bit is only available on the drive CAN bus).
The instantaneous consumption (at a specific time) is then always calculated as (current value - previous value) / time interval.
