A flashing light means you're actively misfiring. Have the ECU scanned to find out which cylinder it is. Bad coil packs are common and there is a recall for them. Call a dealer with your VIN number and if yours qualifies, you'll get four new ones free. If not, buy a coil pack for each cylinder that is indicated as misfiring and replace them. They're $35 at AutoZone and about $160 at an Audi dealer.

If you changed your heater core, it has nothing to do with the car starting. Did you disconnect the battery when you did this? . The only other thing I can think of is a safety switch that won't allow the car to run if the water is low. This can happen if the system gets air locked. How did you fill the system back up? Did you hit any wires off while working on car? Did the car run fine before you changed the heater core? Let me know and we can go from there Cheers from NS Canada
