Hey drago011,

1. If you are planning to do some of the smaller VAGCOM mods (window roll down, fog lights etc), you'll be okay. However, any modifications to the ECU or drivetrain parameters (tuning software, lowering etc) will void your warranty.
2. Stick with Ross-Tech. I understand they are pricier but in terms of comprehensive support and functionality, I have not seen an alternative. Here is a link(Ross-Tech: VAG-COM: Audi A4 / S4 / RS4 Applications) which shows all the control modules accessible for your car through Ross-Tech

Hey greenline4,

Its possible the unit you bought is defective. Your car is compatible with OBD2..maybe try another reader? Or if you can find someone with access to VAGCOM for a more thorough scan...that would be better.

Hey greenline4,

That would be just the VAGCOM cable. You would also need the software to scan. Ross Tech is the premier manufacturer for VAG diagnostic software/hardware. The link is Ross-Tech: Home.

1. You would have a timing belt
2. The Audi interval is every 120K km but should be done earlier if the belt is cracked/frayed. With the timing belt change, you should also do the water pump, tensioner/rollers.
3. If the belt looks damaged or covered in oil, change it right away. If it was changed, there is usually a sticker near the belt covering or under the hood indicating when it was done. Do you have any service records for the vehicle? If you are completely unsure when or if it was done and a visual inspection shows deterioration, then change it.
4. Does the sound occur when the wheel is centred and you are in reverse?

Yes we are located in Toronto (motorfabrik.ca)

Thanks Again
For the VOG Cable , the seller offer the CD of Software, so i guess it s gona be okey.
4.No Sound ( till now ) when the wheel is centered )
5.See the Picture 1 ( drive Mode )
6.See the picture 2 ( Fog Light )
7.What is Mode Sport ? ( Letter S )
Thank You

4. And this sound does not occur in drive? Just when you are in reverse and the car is actually moving backwards?
5. Unfortunately, it looks like the pixels for that part of the display on the cluster are shot. Rare but it happens.
6. Your fog lights are supposed to come on. Check the wiring for the one that is off or possibly a bulb issue.
7. Sport mode holds each gear a little longer...better acceleration pretty much

Thank You Motor F
4. Just when you are in reverse and the car is actually moving backwards ( i can record it if you want )
5. I remark that the Car doesn t change the Speed ( from 1st to 6th) when that happens, i mean when All letters are selected, the Drive speed still the same and number of Tour per minutes doesb t reach 2 000 .....i became crazy...( i can record a video if you want )
6. since the fog light comes one when i start up the car, i guess it s note an issue with wires or bult, what do you think ?

Thanks Again

Hey greenline4,

4. If possible, open the hood and have another person with you to try and determine where the sound is coming from. Reverse slowly and turn the wheel lock to lock. If the sound is coming from the engine bay itself, it may be a tensioner squeeling under load. Odd though that it is only in reverse.
5. Sorry I do not understand. Can you reword please?
6. If both fog lights turn on when the car is started, that it is normal
