the vehicle, »lack of cooling air«.

4 - The selector lever position engaged cannot be recognized.

The Selector Lever Transmission Range Display - Y5-

blinks. Differences in the driving and shifting can definitely

be felt. It is not possible to shift into reverse. There is a »se‐

rious malfunction«, a sub-transmission is switched off,

transmission repair is necessary.

Usual”, page 7

2.3.1

Transmission Range Display, No “R”

Simultaneous lighting of all segments on the transmission range

display indicates the transmission is in emergency mode. The

vehicle can no longer drive in reverse.

2.3.2

Touch Function Malfunction, Not

Changing Gears as Usual

Check the lock washers on the selector lever cable mounting

bracket at the top of the transmission. The washer -B- especially

must never be used twice.
The lock washer -B- can deteriorate if it loses its »residual stress«.

The -arrow- points to the selector lever cable adjustment screw.

»Drive« Faulty - Insufficient Oil Suspec‐

ted

First click here once. Refer to

⇒ “1.5 DSG® Transmission Fluid”, page 3

 .

Only add fluid if it has definitely been seen that oil has leaked out.

Under any other circumstances it is just an »unnecessary ex‐

pense« that does not help.

2.3.4

No Faults are Stored

In this case, it is especially up to the technician to find the solution.

Experience shows that often a »fault« that is attributed to the

transmission was caused by other components or assemblies.
It can be the case that poor shifting behavior is a result of insuf‐

ficient engine air supply. Do not make such a mistake.
If such faults are to be eliminated, work can be performed sensibly

with the VWtester.

Faults are Stored

Find out which faults have been stored. Volkswagen testers offer

Guided Fault Finding

. Using 

Guided Fault Finding

 cor‐

rectly can determine the cause of many malfunctions.

2.3.6

Malfunctions »Outside Transmission«

If, for example, there is a malfunction in the transmission: “ABS

signal missing” is stored in the transmission and perhaps another

control module also says: “ABS signal missing”: Then do not con‐

tinue to suspect the transmission control module is »faulty«.
The entry simply means: the transmission (and possibly other

control modules) is waiting for a signal from the BUS but is not

receiving it. In this case, the ABS control module would have a

problem. The DSG Transmission Mechatronic - J743- must never

be removed here under any circumstances. In this example, the

fault points to problems with the ABS.

Transmission Identification

⇒ “3.1 Transmission Code, Reading”, page 9

Example -arrow-:

GKF - Transmission Code
10.05.2 - 05/10/2002
14 - Plant Code
14 15 - Time
001 - Serial Number

On some transmissions, additional code letters are applied on top

of the transmission near the selector lever cable -arrows-.
The transmission code is also listed on the vehicle data label.
If the vehicle data label is not available, a different transmission

was accidentally installed or there is no definite way to identify the

installed transmission, read the transmission code letters directly

from the transmission.
Reading the code directly off the transmission. Refer to

⇒ “3.1 Transmission Code, Reading”, page 9

 .

3.1

Transmission Code, Reading

The transmission code is on every transmission in at least two

different locations.

-two arrows-.
If these cannot be read or are »on the head«, the transmission

code can also be read under the left subframe mount transmis‐

sion bracket.

To read the transmission code letters under the transmission

bracket directly from the transmission, the engine and transmis‐

sion must be supported. The left subframe mount transmission

bracket -A- must be removed. It is important to lower the engine/

transmission just enough until it is possible to slide the bracket

toward the rear. If lowered any farther, the pendulum support

could be damaged. After being assembled, the selector lever ca‐

ble must be adjusted. Refer to

⇒ “5.6 Selector Lever Cable, Adjusting”, page 80
