If the Check Engine warning lamp suddenly lights up on the above-mentioned vehicle, this may be related to a fault in the DC/DC voltage converter. The first step is to read out the error memory using a diagnostic device (e.g. Hella Gutmann mega- macs X).

When replacing the cabin filter in the above-mentioned vehicles, there are a few special features to bear in mind:

• Remove the right panelling from the centre tunnel
• Remove the panelling under the glove compartment and also disconnect the footwell lamp connector

Every driver is familiar with the "dipped beam" and "main beam" lighting functions. In addition, modern lighting systems offer further possibilities for light distribution and, in compliance with legal requirements, bring out the maximum possible in road illumination. Here you can find out what tips and tricks make this work and what new lighting functions, such as those for country road lighting, really entail.

The tyre pressure monitoring system may fail on the above-mentioned vehicle model. The system must first be re-initialised in order to run a check on it. This procedure depends on each individual vehicle type and details can be found in the vehicle operating instructions. If re-initialisation fails, first check the individual wheel electronics.

St-, st-, starter motor broken? Well, it certainly doesn't sound like the video! But it doesn't matter whether it clicks, spins or doesn't make a sound: Our HELLA Hero has top-quality starters and alternators in its luggage - er ... boot! HELLA - We got that!

On the above-mentioned vehicle model, the display on the instrument cluster may sometimes be offset. This fault occurs after the vehicle has been stationary for a longer period of time and can be rectified for a while again after switching the ignition off/on. This defect may recur at irregular intervals.

If the Check Engine warning lamp comes on in the above-mentioned vehicle and the error code P0401 (EGR system, exhaust gas flow too low) is stored in the control unit, a faulty or clogged EGR valve may be the cause.

The crankshaft sensor is one of the key providers of information of the engine control. It detects the speed and position of the crankshaft and forwards this information to the engine control in the form of an electrical signal. On this page, you can find out how crankshaft sensors work, and what must be taken into account when checking them in order to prevent damage.

In order to be able to adjust lamps, they firstly have to be made accessible. To do this, please proceed as follows:

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

With the above-mentioned vehicle model, it can happen that disturbing rattling noises are heard from the engine compartment shortly after starting the engine. One possible cause could be vibration noises on the actuating rod of the bypass flap on the turbocharger.
