Self-Leveling Suspension (coupe) Audi A5 I

GENERAL REPAIR INFORMATION

General Information

To perform a problem-free and successful repair, extreme caution and cleanliness, as well as properly functioning tools are an important requirement. Understandably, general safety guidelines apply when performing repairs.

A series of applicable general notes for individual repair procedures - otherwise listed several times at many points in the repair information - has been collected here. They apply for this repair information.

1. Thoroughly clean connecting points and their surrounding areas before loosening.
2. Place removed parts on a clean surface and cover to prevent contamination. Use foils and paper. Only use lint-free cloths!
3. Only install clean components: Only unpack replacement parts immediately prior to installation.
4. Use exclusively lubricants and sealants marked with part numbers.
5. Carefully cover or seal open components, if repairs are not carried out immediately.

Seals, Sealing Rings

1. Always replace seals and gaskets.
2. After removing seals/boots, inspect the contact surfaces on housings and shafts for burrs and damage and repair if necessary.

Bolts and Nuts

Scheme 1

1. Loosen and tighten the bolts and nuts of covers and housings in a diagonal sequence.
2. Components that are extremely sensitive must not be distorted and should be loosened and tightened in stages in a diagonal sequence.
3. Torque specifications for unlubricated bolts and nuts are given.
4. Always replace self-locking nuts and bolts.
5. Always replace the bolts and nuts, which are tightened with an additional tightening angle.

Electrical Components

Surely everyone has been shocked at one time or another when coming into contact with a metal object. The reason for this is the build-up of static electricity in the human body. This build-up can lead to malfunctions when contacting electrical components.

Touch a grounded object - for example a water pipe or a vehicle hoist - before working on electrical components. Do not make direct contact on connector terminals.

DYNAMIC RIDE CONTROL (DRC)

The DRC counteracts the pitching and rolling motions of the vehicle body around the longitudinal and cross axles and thus optimizes the vehicle driving characteristics. The Audi RS 5 has a DRC with a variable damping that can be shifted.

In addition to reducing the pitching and rolling motions of the vehicle body (identical to the hydraulic DRC), the adjustable DRC with variable damping allows the driver to adjust and the damping level using the Audi drive select controls. Each shock absorber has an additional component with an integrated electric motor. The electronic damping control module -J250- controls the electric motors.

There are several damping settings

1. "COMFORT"
2. "DYNAMIC"
3. "AUTO"
4. "INDIVIDUAL"

Only approved oil for filling and draining must be used. .

Filling must only be performed at ambient temperature of approximately 20 °C (68 °C).

As a replacement part, shock absorbers and lines are delivered empty.

Lines/dampers and central valves may only be suctioned, evacuated and filled when they are installed and connected.

When the DRC system is disconnected from the individual components (for example, the connection between the line/damper/central valve), the vehicle must not be standing on its wheels.

While filling the DRC system, the gas reservoir to the pressure clamps is checked for leaks on the piston on the inside of the central valve.

If, while filling of the DRC system, a pressure of 22 bar cannot be reached or continually drops, then check all connections for damage and leakage. If no issues are found on the outside, the gas reservoir to the pressure clamps on the piston on the inside of the central valve is leaking. Replace the central valve.

If the DRC system is being extracted, evacuated or filled, then this must be performed on the front and rear extraction/filling valves for each damper line. Note the following

Before removing or disconnecting any DRC components, extract the affected line completely.

Shock absorbers must only be filled when installed and connected.

Vehicle must never be placed on wheels with closed, filled system and locked central valves. This inevitably leads to leaks and system malfunction.

Lines must not be bent.

Small oil leak with locked central valve which results from connecting or disconnected charging device V.A.S 6209/2 at connection is not critical. Avoid repeating measurements because a small quantity of oil is removed from the system every time the V.A.S 6209/2 is connected. Every connection results in a pressure decrease of approximately 0.3 bar from the previous reading. Multiple repeated measurements decrease system pressure below minimum pressure or failure.

DYNAMIC RIDE CONTROL (DRC), DRAINING AND FILLING

Note. Extracting, evacuating and filling the whole DRC line (lines/damper and central valve) is performed with the Filling device for DRC system VAS 6544 Depending on the DRC system equipment in the dealership, the equipment may need to modified or updated to match VAS 6544. The following choices are possible

Special tools and workshop equipment required

1. Upgrade kit, Filling device for DRC system VAS 6209/4. The VAS 6209/4 serves as an upgrade to the charging device for DRC system VAS 6209 already found in dealerships.
2. Retrofit kit, DRC system VAS 6209/5. The VAS 6209/5 is needed if the dealership has the pressure pump VAS 6209/3 and wants to upgrade the filling device for DRC system VAS 6544. The supplement set, DRC system VAS 6209/6 is also necessary.
3. Supplement set, DRC system VAS 6209/6. The VAS 6209/6 is needed up upgrade the already available pressure pump VAS 6209/3 in the filling device for DRC system VAS 6544. The requirement is that the dealership already have the charging device for DRC system VAS 6209. If the dealership does have the charging device for DRC system VAS 6209, then the retrofit kit, DRC system VAS 6209/5 must be obtained.
4. Charging device for DRC system VAS 6544

Note. Updating the equipment for the DRC system must be done one time only. It is not necessary to convert back again. The procedure for draining and filling the complete DRC system is described using the V.A.S 6544.

Only approved oil for filling and draining must be used.

As a replacement part, shock absorbers and lines are delivered empty.

Filling must only be performed at ambient temperature of approximately 20 °C (68 °F).

Lines/dampers and central valves may only be suctioned, evacuated and filled when they are installed and connected.

Note. The shut-off valve for the wiring harness at the central valve must remain open when extracting, evacuating and filling the DRC system (lines/damper and central valve).

While filling the DRC system, the gas reservoir to the pressure clamps is automatically checked for leaks at the piston in the central valve.

Valves of filling device are open when ratchet levers are parallel to direction of flow.

Note. The valves must be kept closed during transport and storing the VAS 6544.

Lines must not be bent.

When the pressure manometer shows approximately negative 0.9 bar, close the valve -C- and disconnect the compressed air hose from the Venturi injectors.

1. Check for leaks.

Note. Vacuum must be stable for at least 2 minutes at negative 0.9 bar.

Check the oil level on the oil reservoir, fill with new oil up to the marking if necessary and position the o-ring to the height of the oil level.

Filling

Open the needle valve -B- approximately 2 turns and let the oil run out of the oil reservoir on the VAS 6544 into the evacuated DRC system.

Oil flows from the reservoir into the connected DRC system. This is shown by the decreasing oil level in the oil reservoir. Depending on the amount of oil remaining after extraction, the procedure may take several minutes. As the system fills up, the oil level goes down slower. If the level of the oil no longer moves, the first step of the filling process is complete.

Close the needle valve -B-.

Open the valve -A- and fill the DRC system to 22 bar by pumping the lever on the hand pump -1- several times.

Special tools and workshop equipment required

1. Charging device V.A.S 6209/2
2. Hand vacuum pump VAS 6213

Bleed charging device V.A.S 6209/2

Use only approved oil for the bleeding procedure.

Note. Charging device V.A.S 6209/2 must always be bled at initial use. If charging device V.A.S 6209/2 still shows a residual pressure greater than 0.5 bar (e.g. from a previous reading), bleeding must not be done.

To bleed pressure gauge -B- and line section -A-, install special tool as shown in illustration.

Scheme 15

Note. Illustration shows bleeding process by extracting hydraulic oil with VAS 6213

Bleed process must be performed until air bubbles are no longer visible in hose -C-.

Disconnect hose -C- and -D- and perform system pressure check.

System pressure check is performed on front shock absorber of corresponding DRC line.

Scheme 16

Remove the cap from the extract/fill valve and connect the V.A.S 6209/2.

Read system pressure at V.A.S 6209/2.

Note. Pressure increase at V.A.S 6209/2 occurs slowly and takes approximately 2 minutes. DRC system pressure can only be read when V.A.S 6209/2 needle has finally come to a stop.

Disconnect V.A.S 6209/2 and install dust cap.

Note. Small oil leak which results from connecting or disconnected V.A.S 6209/2 at connection is not critical. Avoid repeating measurements because a small quantity of oil is removed from the system every time the V.A.S 6209/2 is connected. Every connection results in a pressure decrease of approximately 0.3 bar from the previous reading. Multiple repeated measurements decrease system pressure below minimum pressure or failure.

If the pressure is not OK, determine the cause and service the system.

DRC System Pressure Values

Pressure values refer to reference temperature of 20 °C (68 °F).

1. 20 bar (290 PSI) = operating pressure
2. 19 - 20 bar (276 - 290 PSI) = central valve new or as good as new.
3. 18 - 19 bar (261 - 276 PSI) = normal range of operation, system OK.
4. < 18 bar (261 PSI) = system leaking or not filled completely, air entering system, central valve has no pressure/is empty.
