My ETS light is on and my 2000 Volvo S70 won't start.

Your heater core is leaking. The smell and smoke is from the coolant evaporation.

You must take the car to a Volvo dealer so they can reference the code from the VIN number. If you call it in, they only assume you stole the radio. Sometimes you have to prove you own the car.

SOURCE: Volvo S70 won't start - battery, generator, or other

usually multiple clicking (like a machine gun) does indicate lw battery voltage. did you get 11.9 volts with it running or car off? with running you should be over 13.6 min up to 14.0 volts. these cars have a fair amount of electronics with some residual voltage draws which may shorten battery life. 4 yrs is not too bad. i would consider replacing battery

Just to add to it. Volvo Darin is right, but the extended warranty period was for 10 years or 200,000 miles. It depends on your warranty start date. Being a 1999 it could or could not be covered.
Don't wait any longer, because there is NO help or extension of this warranty after 10 years.

I had the same problem with the 2000 v70 XC I bought in Dec. 08. I replaced the battery, then the antenna ring (around ignition; part of the immobilizer system), and bought new keys as sometimes the chips in them do go bad. Also, if you have a key for another car with an immobilizer system on the same keyring, take it off. The multiple signals can confuse the immobilizer system. I think the antenna ring may have been one issue as, consistent with what repairpal stated, I got a crank and the engined turned over for about a second or 2 one time and then it died. The antenna ring (and the new keys) were relatively inexpensive. That worked for about a month and then I got no crank at all.  I had the starter replaced, but in hindsight I think that may have not been the problem.  I think the problem was the starter not getting juice. The starter was a very expensive solution. About 2 weeks after having the starter replaced, it wouldn't crank again.  I took it to a Volvo dealership and gave them the history. They found a corroded wire near the starter and, at least until now, that seems to have done the trick. Labor on the wire was about $100 at the dealer. Searching Volvo forums for those who have had a similar problem, I have found that others have had the "bad wire" problem.  If you are told to replace the starter by your mechanic, my advice to anyone having this problem is to have check to make sure the starter is getting juice before replacing the starter as replacing the starter (parts and labor) cost me about $650-$700.  If they find that the starter is not getting juice, they can check for wire corrision starting at the starter and working their way back.
