Question about 1999 Volvo V70
Disconnected battery and did not affect the noise. 1999 V70 single owner non-turbo. Filled gas up about 4 miles before noise started. took off gas cap and di not make a difference
SOURCE: 1999 volvo v70 xc gas tank
Option 1 the easiest way is to jump the fuel pump relay with the fuel feed line at the engine disconnected from the engine and connected to some sort of catch basin (bucket, gas can, etc.) this allows you to use the vehicles fuel pump to drain the fuel. All you have to do is find the fuel pump relay, then jump the positive side (key off) to power to make the fuel pump run, use that to pump all the bad fuel out.
Option 2 is to remove the filler neck and check valve from the tank (a real pain on that car)
Option 3 is to remove and drain the tank... this is the most costly and time consuming option as the alldata labor guide quotes 8 hours labor time.. so i would advise option 1
As for damage to the vehicle/engine that is always possible with a contaminated fuel, my advice would be just to get the bad fuel out as soon as possible, get good gas in it and give it a try.

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.

The noise is coming from the blend door motors.
All of the climate control doors (vents, defroster, temperature, recirculation etc) are controlled by electronic motors. As the motors age they tend to make a buzzing noise when they move.
There is a software upgrade that is available to minimize the noise, but it will always make the noise to some degree.
Hope this helps.

Vacume line off of transmission won't alow high gear and at that speed the tranny starts screaming for relief. Find the vucume line and make sure its good and connected at both ends
