Technical product information
Engine temperature display fluctuates between 50° and 90° C - all TDI
Customer statement / workshop findings
At outside temperatures under 5°C the engine temperature fluctuates 
according to the display in the dash insert between 50 and 70°C or till 
the coolant temperature reaches 90°C. The phenomenon occurs mainly when 
driving at low engine speed.
Technical background
Because of a very good effectiveness of the engine in low rev range, 
little engine heat is passed on to the coolant. At low outside 
temperatures the coolant temperature does not reach 90°C. If the heating 
is used, the coolant loses further heat depending on the blower level. 
As a result, the coolant temperature can fluctuate between 50° and 90° C.
Below an outside temperature of 5° C and a coolant temperature of 70° C 
the standard PTC auxiliary heater is activated, to heat the interior.
Measure
Please do not repair, this is normal.
Customer information
A low coolant temperature has no effect on the service life of the 
engine. An engine oil with suitable viscosity is used.
