With the above-mentioned vehicles, a sudden drop in engine performance may occur after the operating temperature has been reached. Often no error is stored in the control unit. A defective fuel temperature sensor can be the cause of the trouble.

The above-mentioned vehicles may experience a sudden loss of power. The engine control lamp lights up. Error code P2015 (intake manifold flaps/flap control for intake manifold) is stored in the control unit where appropriate.

Correct headlamp adjustment is a very important safety issue which is frequently underestimated. If the headlamps are set too low, the field of vision is limited during darkness. If they are too high, they dazzle and impair the view of other road users. On this page find out what requirements must be met for the correct headlamp adjustment, and how both classic and modern lighting systems can be tested.

Changing the cabin air filter on this vehicle requires some skill, otherwise the entire front mask has to be dismantled. Proceed as follows when renewing filter:
 

• Remove the ventilation grille on the right under the windscreen
• First turn the screw in the grille using a suitable tool in order to release the locking mechanism.

On the vehicles mentioned above, the vehicle may pull to one side even though the steering wheel is in the straight-ahead position. Often the following measures have already been performed, which make sense but have not led to success:
 

• Tyre pressure checked
• Axle parts/axle suspension checked (joint/bearing play; spring broken, shock absorber defective etc.)

On the above-mentioned vehicles, bulbs for halogen headlamps can be replaced as follows:
 

• Switch off the ignition
• Disconnect the headlamp from the power supply by unplugging the electrical supply line

The ignition coil generates the high voltage required to ignite the fuel/air mixture in gasoline engines. On this page you can find out how ignition coils work and which designs are used in the latest generation of vehicles, for example. You will also find a wealth of practical tips for diagnostics and checks on ignition coils.

Regeneration of the diesel particulate filter may no longer be carried out on the above-mentioned vehicle type. Regeneration using a suitable diagnostic device (forced regeneration) is also not possible.

In the above-mentioned vehicle, the cabin air filter is located in the driver's footwell on the right-hand side. In order to replace the filter, you should proceed as follows:

The classic low beam is in fact a compromise solution, and it's not without its weaknesses. Thanks to its new light functions, the Advanced Front Lighting System (AFS) eliminates the rigid boundaries of the low beam, thereby significantly improving visibility in the dark and in poor weather. HELLA's VarioX technology forms the basis for this. On this page you will find out which new light functions have been made possible by AFS and what advantages they bring.
