Question about 2000 Volkswagen Beetle
This is a intermittant problem. When down shifting and coming to a stop the car will die. You can turn the key off and start it right back up. Today I noticed that when it would die the battery light would come on. But I doubt its the battery as every time it starts right back up. I pulled the codes from the parts store and Mass Air Flow sensor A Circuit is High, Intake Air Temp Sensor 1 Circuit Low Bank 1, Engine coolant temperature censor circuit short to ground, cooling system malfunction, multiple cylinder misfire. The car sat for most of the winter and this is the first time I have ever drove it. It supposedly has a new battery and alternator and only has 100k miles. This morning it was sputtering like it had bad gas which i believe is the reason it the cylinder misfire. I put seafoam in it and the sputtering went away and it drove better. My husband will change the fuel filter tonight. Does anyone know what is causing it to die when coming to a stop.
Clean the MAF sensor with MAF sensor cleaner. Replace the engine coolant temp sensor. Also I would suggest adding Sta-bil a brand name fuel gel dispersant. This will break down the gelling, this is what happens when fuel sets too long. I have used sta-bil many times when an engine would not start or ran rough and stalled at idle. The battery light comes on when the vehicle is below normal RPM and has stalled or is ready to stall.

I agree with Adam on that one.all the bad gas needs out even before you change the fuel filter. sea-foam will help til then. i would recommend a new air filter and cleaning the MAF sensor. they sell a spray for that at Autozone. i would even go as far to say if it sat all winter then after you get the bad gas out. change the spark plugs too. If you plan on letting it sit next winter then put some Starton ethanol enzyme treatment( in blue bottle) you fuel. the ethanol in fuel now makes gas go bad quickly ( less than a month) and draw moisture. Also have Autozone or other part store to check you battery and alternator. either of them having a problem can cause engine light codes. and sputtering/stalling also.

You might have bad gas when it sits for months the gas will separate. best to do is run all the gas out of it till it stops running. have a 2 gallon or 5 gallon gas can with you and fill it up when it finally stops. the other thing you can look for is a rust ground. I had this problem with a saab 9-3 took me months to figure it out. the battery and alternator you can go to any local parts store and have them test the charging system to see if there is any problems
