My 1996 audi A6 quattro is overheating and blowing white smoke out of the tail pipe. I have replaced the water pump and valve cover gaskets however the problem still persists. There is a crack in the coolant resvoir which is causing a coolant leak, does this explain the overheating problem? I also believe it may be a blown headgasket. Are there any other possible causes of these problems?

You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.

I think I can help you. I just did this on mine yesterday because my clock runs a few minutes fast each month. It was somewhere bizarre - sorry I'm not near the car to be more clear. I think I picked Sound, Settings and for some odd reason, it was there, rather than in Car, Settings. NOOO - it was in Tuning - click the AM/FM button, then Settings. I've only had it for a few months, but you'd think I'd have that one figured out due to re-setting it.

If its blue smoke then your valve stem seals are worn and that is allowing oil to enter the cylinders and burning with the gas.

it doesn't matter what brand you use, just make sure you use the motor weight on the cap (don't use Pennzoil)
