1999 audi a6 hard to start but runs smooth otherwise

You will need the systems control module scanned for fault codes, when the light is on a code is in memory.

its a scandinavian version ,,,the lights automaticly come on .

When the light stays on it indicates a fault is occurring in the system. In order to repair this you first need the control module scanned for fault codes and then careful diagnosis will reveal the failed part.

First of all you should access the Airbag ECU (Electronic Control Module) using suitable diagnostic equipment (VAS, VAG-COM) connected to the data link connector of the car in order to erase all faults - DTC's (Diagnostic Trouble Code) memored, unlock and reset the Airbag ECU. Then the Airbag light will turn OFF after approx. 4 seconds, ignition ON.
Good Luck!

It sounds like you have more than one problem with your Audi. The coolant leak and the ignition switch are two separate issues. I would recommend that you take the car to the Audi dealer or to an independent garage that specializes on German cars and have the vehicle checked.

IMPORTANT NOTE: You must have the security anti-theft code for your Audi radio from the car manufacturer, or from an Audi dealer!

The sequence of programming for 2000 Audi A4 radio is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
3. By the #1 key you will set up the first safe code digit.
4. By the #2 key you will set up the second safe code digit.
5. By the #3 key you will set up the third safe code digit.
6. By the #4 key you will set up the four-th safe code digit.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed. The radio is now ready for use!

That indicates that the ABS controller is having issues. The ABS controller is the metal box along the driver's side of the engine, just in front of the coolant overflow tank. The controller is the black box on top of it with the harness attached. You can buy a new one (expensive) or send yours to www.modulemaster.com for a warrantied rebuild. They have a great reputation on the Audi forums I frequent, and you can drive the car while it's gone (you just won't have functioning ABS while it's gone).

IMPORTANT NOTE: You must have the security anti-theft code for yours Audi Concert radio from the car manufacturer! For Audi Concert the sequence of programming is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
3. By the #1 key you will set up the first safe code digit.
4. By the #2 key you will set up the second safe code digit.
5. By the #3 key you will set up the third safe code digit.
6. By the #4 key you will set up the four-th safe code digit.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed. The radio is now ready for use!

Please rate my response. Thanks !

Yes. Because the security system was "set". You need the code to unlock the security system for the radio. It is like that for theft pruposes. Best bet is to go to the dealership to have them reset it or figure out how to get the code for your radio.

It's a transmission system failure. Take it to an Audi dealer or a euro-car specialist. When the indicators light up like that, there IS a transmission fault code stored in the controller. The shop can use diagnostic software to retrieve the code so they can fix the problem. There are several things that can cause this to happen, so you have to have that code scanned before you can start to repair it.
