September 15, 2008

Vehicle Information

Radio reception and playback problems

Condition

The customer may report constant sound interference in the radio. The sound may be distorted, or a humming or hissing noise may be audible in all

speakers.

Technical Background

If the reception level is good, the problem may be caused by aftermarket equipment that is plugged into the cigarette lighter or one of the power

outlets. Insufficient radio interference suppression of rechargers and power supply units of mobile telephones, navigation systems and other

electronic devices may cause voltage interference in the on-board network.

Production Solution

Not applicable.

Service

1. Verify if aftermarket devices were installed in the vehicle.

2. Disconnect the aftermarket devices, if applicable.

3. Inform the customer if the interference disappears after removal of a plugged-in aftermarket device.

February 9, 2009

Vehicle Information

Condition

The customer may report that personalized memory settings (for example, electric exterior mirror, seat memory, radio, air conditioning, electric

steering wheel, etc.) are inoperative or incorrectly assigned when using the remote key.

Technical Background

The memory settings for each key are stored in the individual control unit (depending on the function) and not in the key itself.

Only the identification of the currently used remote key is transmitted on the CAN bus. Each participating control unit sets its own adjustments.

Production Solution

Not applicable.

Service

To rule out the key as the root cause, check whether the remote key is correctly identified by the vehicle.

TIP:

Only keys on positions 1 to 4 are included in the personalized memory settings functions. Keys from position 5 cannot be personalized.

- A3, TT, R8: Check MVB 10 in the convenience control unit (address word 46).

- A4 (B7), A4 Cabriolet: Check MVB 7 in the convenience control unit (address word 46).

- A4 (B8), A5, Q5: Check MVB 10 in the control unit for access/start authorization (address word 05).

- A6, Q7: Check MVB 11 in the control unit for access/start authorization (address word 05).

- A8: Check MVB 6 in the control unit for access/start authorization (address word 05).

Vehicle Information

Parking aid warning sound without obstacle

Condition

The parking assist system warns of obstacles when there are no obstacles around the vehicle.

Technical Background

Several reasons can lead to an unjustified warning sound of the parking assist system.

- One or more sensors are incorrectly mounted (see attachments) and the bumper is detected as an obstacle.

- Dirt, salt, ice, snow etc. might cover one or more parking assist sensors.

- Without single frame radiator: If the license plate holder is attached with only 2 bolts, the holder might protrude due to the uneven surface of

the bumper.

- With single frame radiator: If the license plate holder is not correctly installed, it might be detected as an obstacle.

Production Solution

No change.

Service

1. Check for parking assist system-related diagnostic trouble codes. If present, follow Guided Fault Finding to solve the concern.

2. Verify that all parking assist sensors are mounted properly. Remount parking assist sensors if necessary.

3. Verify sensor brackets are not broken. (Bumper removal is not necessary for the check.) Replace brackets, if broken.

4. Verify that the sensors are not covered by dirt, ice, salt, etc. Clean if necessary and inform customer.

5. If a license plate holder is mounted improperly:

- Without single frame radiator: The license plate holder must be attached with 4 bolts.

- With single frame radiator: Install the license plate holder correctly.

Warranty

Accounting for incorrectly fitted license plate holder and for cleaning of the sensors under warranty is not permitted.

Vehicle Information

Condition

Battery testing and charging must take place directly at the battery for vehicles that meet all of the following four conditions:

- Batteries are located in the trunk area.

- Jumper posts are located in the engine compartment.

- Vehicle does not have a battery energy manager (BEM).

- Vehicle may or may not have a battery monitoring control module, J367.

Technical Background

Inaccurate test results will occur if the testing and/or charging takes place at the jumper posts in the engine compartment. This is due to the added

resistance in the system between the battery and jumper posts.

Production Solution

Not applicable.

Service

Testing the battery

Midtronics MCR340V handheld tester for all vehicles:

1. Connect the tester directly to the battery posts.

2. Enter the DIN value listed on the battery.

1. Connect the charging station directly to the battery posts.

2. Enter the DIN value listed on the battery.

VAS scan tool for vehicles with J367:

Follow Guided Fault Finding battery test plan in service work.

Charging the battery

Midtronics INC-940 diagnostic charging station:

1. Connect the charging station.

- For vehicles equipped with a battery monitoring control module (J367): Connect the InCharge 940 negative cable where the vehicle's

negative cable connects to J367. J367 is mounted directly to battery negative post.

TIP:

This connection will allow J367 to remain in the loop so that it may provide battery charge data to the Gateway, J533.

- For all other vehicles: Connect the charging station directly to the battery posts.

Several reasons can lead to an unjustified warning sound of the parking assist system.

- One or more sensors are incorrectly mounted (see attachments) and the bumper is detected as an obstacle.

- Dirt, salt, ice, snow etc. might cover one or more parking assist sensors.

- Without single frame radiator: If the license plate holder is attached with only 2 bolts, the holder might protrude due to the uneven surface of

the bumper.

- With single frame radiator: If the license plate holder is not correctly installed, it might be detected as an obstacle.

Production Solution
