GENERAL INFORMATION
Note. Use only new Original VW / Audi brake fluid.
| WARNING | Brake fluid is poisonous. Do not let brake fluid come in contact with the paint. Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore always be stored in air-tight containers. |
Please observe the following
Scheme 1
- Fluid level must be at MAX mark
Note. To prevent the brake fluid from overflowing from the reservoir, the level must not be over the MAX mark.
Note. Use only new Original VW / Audi brake fluid
change brake fluid with brake charger/bleeder unit VAS 5234
| WARNING | Brake fluid must never come into contact with fluids containing mineral oils (oil, gas, cleaning solutions). Oils containing minerals damage plugs and sleeves on brake systems. Brake fluid is poisonous and must not be extracted by mouth using a hose under any circumstances. In addition, it must not come into contact with paint due to is corrosive effects. Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore always be stored in air-tight containers. Observe waste disposal regulations! |
Note. Always use an original air filter insert. Before installing, make sure there is no oil or grease on the hose connections and hoses around the intake area. Do not use any lubricant containing silicone when installing. The air filter housing must be clean. Secure all hose connections with hose clamps that match current standard production. Before installing, spray the screw clamps with rust remover so that they can be used to secure the air guide hoses onto the connections. When cleaning the air filter housing using compressed air, note the following: to avoid malfunctions, cover the critical air distribution components such as the air guide tubes etc. with a clean cloth. Always follow the instructions for disposal!
Blow out the water drain with compressed air.
Clean out any salt build-up, dirt or leaves from the air filter housing (both upper and lower parts) using a vacuum.
Check the air guide hose (clean air side) for salt build-up, dirt and leaves.
Check the air guide going from the lock carrier to the air filter housing for dirt and leaves.
When installing the air filter insert, be sure to center the insert when installing it into the air filter housing lower section mount.
Gently place the air filter housing upper section onto the air filter housing lower section. Make sure the air filter housing upper section is sitting angled on the air filter insert (note the sealing lip on the air filter insert).
Installation is the reverse of removal.
Note. Please follow specified engine oil capacity and oil standards in Maintenance, Diagnosis
Engines with turbocharger
After the engine oil and oil filter have been replaced, observe the following when first starting the engine
- As long as the oil pressure indicator lamp in the instrument cluster is on, the engine may only run in idle. Do not touch the accelerator pedal! Bumping the accelerator pedal can damage the turbocharger or destroy it completely
- The full oil pressure achieved and the engine can be accelerated only when the warning light extinguishes
All
Check the oil level.
DUST AND POLLEN FILTER WITH ACTIVATED CHARCOAL INSERT, GENERAL INFORMATION
- The dust and pollen filter is available in different versions, without and with a filter insert with activated charcoal, A dust and pollen filter with activated charcoal insert is currently installed in vehicles with the "Comfort" air conditioning system. A dust and pollen filter without activated charcoal insert is currently installed in vehicles with the "Basis" air conditioning system.
- The dust and pollen filter with additional activated charcoal filter insert is installed in vehicles with the "Comfort" air conditioning system. These vehicles also have an air quality sensor -G238- installed.
- The filter with the activated charcoal insert performs the same task as the dust and pollen filter. It can also filter gaseous pollutants such as ozone, benzene, nitrogen, etc. out of the air inside the vehicle. The basic task of the activated charcoal insert in the dust and pollen filter is to keep peak loads out of the passenger compartment.
- The activated charcoal insert also removes certain gaseous contaminants from the air inside the vehicle. The activated charcoal layer in the dust and pollen filter works different on various pollutants in the air
certain pollutants are trapped in the activated charcoal layer.
others are converted to harmless compounds as in a catalytic converter.
for the remainder, the activated charcoal functions as a condenser. When the load increased, pollutants are first absorbed until a certain saturation point is reached. If the amount of pollutant decreases, the activated charcoal layer continuously releases the absorbed particles.
- Because the activated charcoal layer also absorbs a portion of the gaseous particles permanently in addition to dust and pollen, the filter may need to be changed earlier than specified when under the following conditions
When operating the vehicle in areas with continuous heavy air pollution. The activated charcoal layer in the dust and pollen filter is saturated earlier than intended.
When operating the vehicle with the "automatic recirculation" function switched off most of the time.
- On vehicles with an air quality sensor -G238-, the air conditioning system should be operated in the "automatic recirculation" function as much as possible. However, if it is necessary or desired to switch the function off, observe the following
The activated charcoal layer in the dust and pollen filter will become saturated after a certain amount of time.
A saturated filter cannot absorb any more pollutants so they will enter the vehicle.
- The basic task of the activated charcoal insert in the dust and pollen filter and the air quality sensor -G238- is to keep peak loads out of the passenger compartment. Keep the following in mind
If the vehicle is traveling in an area with relatively clean air (with minimal gaseous pollutants in the air), the system will switch from fresh air mode to recirculation mode at a different time than when traveling an area with a high constant level of pollutants (e.g. an industrial area).
The switch from fresh air mode to recirculation mode always takes place whenever the amount of pollutants increases, regardless of what the constant level is (e.g. when driving in the exhaust cloud from a diesel truck).
