VAG-COM: Useful Fabia Codes

[ColinD]

Some common VAG-COM Options for the FABIA.
Common operations

ANTI HIJACK
The anti hijack is a superb feature....

[Select]
[46 - Cent. Conv.] (35 - Cent. Locking for manual window cars)
[Adaptation - 10]
Channel (03..08)
Adaptation Value (1 = on, 0 = off)
[Save]

Channel 03 Auto Lock
Channel 04 Auto Unlock
Channel 05 Unlock, horn sounds
Channel 06 Lock, horn sounds
Channel 07 Unlock, turn signals flash
Channel 08 Lock, turn signals flash


Remember to do a scan of the module on each one to find out what each channel is, prior to making any changes as some cars beep is channel 7, not channel 6.

SINGLE DOOR UNLOCK

[Select]
[46 - Cent. Conv.] (35 - Cent. Locking for manual window cars)
[Recode - 07]
Write down the existing coding for future reference.
Enter 5-digit code from below
[Do It!]

Look at the existing Soft. Coding. If you have selective unlocking (press the unlock button on the remote once to open the driver's door, twice to open all the doors) the last digit of your coding should be an even number. To make all doors unlock, add 1 to the coding.

So, if you have a 2-door 2002 GTI that is coded for selective unlocking (00064) add one to make it 00065 so that all doors unlock with one press of the unlock button.

POWER STEERING
[Select]
[44 - Steering Assist] (from Chassis tab)
[Recode - 07]

Take note of the value which is in the form 0001x1 where x is the weight setting, eg 000121
If x is set to 1, it will be very light, if it is set to 5 it will be heavy
Replace the number with the required weight, eg 000151
[Do It!]


HEADLAMP ADJUSTMENT: (Xenon only)

[Select]
[55 - H. Light Range]
[Basic Settings - 04]
Set channel to "000"
[Do It!]
Wait about 20 seconds
Manually adjust headlamps
[Done, Go back]



EGR DISABLING
With the engine warmed up and running at idle in neutral with all major accessories such as air conditioning turned off, connect the scan tool cable and start the scan tool software.

[01 - Engine]
[Login - 11] and enter 12233 as the access code
[Adaptation] and go to block 3.
Give the accelerator pedal a quick "blip" to ensure that the EGR remains turned on for the next minute while you perform the following steps.
Note that the display shows a default adaptation value of 32768 and shows approximately 250 +/- 20 mg/stroke of air intake volume.

If all is well, enter 33768 as the new adaptation value, and select "test". Note that the displayed air intake volume changes, usually to about 370 mg/stroke. The specification limit is 370 mg/stroke, so if you want to remain within OEM shop manual specifications for emission control reasons, you might have to enter a number slightly smaller than 33768. (If you don't care about road-legal NOx emission limits then leave it at 33768. [Depending on the usage cycle, NOx at this setting can be increased by as much as 40%]) If all is well and you have a seting that you are happy with which results in an intake air volume of 370 mg/stroke or just a hair less, enter [Save]. The values aren't exactly the same, but when you enter the value 33768, the ECU will automatically adapt it. In my case it was something like 33628. 370mg/stroke is what your looking for.

Good Guide

Do you know the VAG Com procedure for resetting the heating flap when you get extremes of temp ? seems to be quite a common thing too?

As said by the master


The heater reset is easy to do, as follows.

08 Heater/A.C
04 Basic settings
Channel 000
001
002

When it goes into a channel let it run until the numbers stop moving. The numbers mean the flap is moving from one stop to the other. Should at the end read 0. Then clear any fault codes.

Many thanks

Indeed - I did this very thing when rewiring in my heating system ( for the second time )

Is the channel 5 and 6 bit in the anti-hijack section the "beep" when locking/unlocking that Hellfire was on about in the other thread? Good to know for the future if it is.

Yep

What actually makes the "beep" as well. And if someone says the alarm horn then.... "oh well" (I have not got one fitted )

[grecianite]

This is digging up an old thread. But does anyone know what actually does go beep?

I'm off to the dealers tomorrow and am going to (fingers crossed), get them to program the car for anti-hijack, non selective door unlocking, pull out the key and all of the doors unlock and possible a beep for the unlock as long as it is not the full on horn!
