Service Info: Insufficient heating performance Release date: 20-Jan-2011
Customer statement / workshop findings
The engine only slowly reaches its operative temperature or it does not reach it at all; the heating performance is insufficient.
Technical background
When driving at low rpm and with small load under low outside temperatures, it happens that the highly effective TDI Diesel engines very slowly reach their operative temperatures. In these cases, the heat exchanger for heating the interior has less energy at its disposal and therefore it takes longer time before the heating reaches its full performance.
The lower temperature of the coolant does not influence the engine lifetime!
Production change
Measure
If the engine temperature increases with increasing load and reaches the operative value, it is not necessary to carry out further checks or to exchange parts (e.g. thermostat), with which you do not clearly find a defective function.
Warranty accounting instructions
Repairs based on the above claims cannot be charged as warranty claims.
The unjustifiably replaced parts will be charged back.
