When driving in severe wet weather there is a risk of water entering the intake system which can result in deteriorating engine functionality. In order to prevent water from entering into the intake system an air filter housing with water separator is fitted. It is essential that the car is updated with new software designed for the new air filter housing.
In addition, the new software for the V6 diesel engine management system has been improved in a range of areas, including:
|
-
|
reduction of vibrations and jerking at low engine speed and light load
|
|
-
|
reduction of jerking at high engine speed and light load
|
|
-
|
reduction of black smoke with acceleration
|
|
-
|
performance at starting
|
In order to reduce the blackening of the rear bumper shell, a new tail pipe is fitted on the exhaust pipe.
