Resistance values

The diagram refers to the coolant temperature sender -G62- and the intake air temperature sender -G42-

The diagram is divided into two temperature ranges:

A -	from 0…50 °C

B -	from 50…105 °C

Examples:

t	30 °C is in range A and corresponds to a resistance of 1,5…2,0 kΩ

t	80 °C is in range B and corresponds to a resistance of 275…375 Ω

Removing the air filter

–	Loosen securing bolts marked with -arrows- to remove air filter.

Note!

t	When the securing bolts are loosened or tightened using a power tool, the threads in the intake tube may be damaged. For this reason, only use a power tool in the following conditions:
