Question about 2001 Volkswagen Beetle

7 Answers

2002 vw floods when i start it and revs high until it warms up.

Will also periodically idle roughly for no reason. The black wire coming out of the fuse box located on top of the battery also gets very warm to the touch but does not blow the fuse. Are all these problems related and how do I fix them?

    I think this may be more than that. It just started out of the blue. It is flooding so badly that I have to pump the gas and get a flood smoke cloud when I finally get it to start. What does the black wire coming out of the fuse box over the battery go to?

  • scottrm1971 Jun 20, 2009

    The connections are all good. I checked that in the beginning. Thanks

  • scottrm1971 Jun 21, 2009

    No engine lights are coming on. This is a gasoline engine.

  • scottrm1971 Jun 21, 2009

    It has been recently tuned up. It only has 58000 miles on it. After it warms up it idles perfectly. When I first get it started it revs up to about 2500 rpms and hesitates when u give it gas. Once it runs for about 4 or 5 minutes it starts revving up and down until it finally kicks down and starts running smooth. It's almost like there is maybe the cold idle settings are overcompensating. The black wire coming out of the fuse box is also getting hot. What does it go to??

  • scottrm1971 Jun 21, 2009

    I am not sure what the black wire goes to. My big problem is the flooding issue when I first start the motor. It is very hard to start and when I do get it started it is flooding very badly. It seems to be worse if the motor is warmed up some but not completely hot. What is strange is that it runs perfectly when it gets hot.

  • scottrm1971 Jun 22, 2009

    This wire can make the engine race????? Can it damage the engine???

  • scottrm1971 Jun 22, 2009

    The black wire is a hot wire coming out of the top of the fuse panel over the battery. I think it is one of five wires. I believe it is coming off of the alternator possibly but that is just a guess. It is one of the fused wires. This isn't a ground wire. Can you please explain more??

  • scottrm1971 Jun 22, 2009

    An update. Came back to the car after a day and a half and it started beautifully. No issues what-so-ever. What is going on?????

  • scottrm1971 Jun 24, 2009

    It still is revving unusual for some reason. It is just coming and going. The black wire I mentioned coming out of the box over the battery, what does it go to? It is still getting very warm although not hot enough to melt anything. It is much warmer than the red wires next to it. It seems like when it gets really warm is when the motor starts idling funny and thereafter when I start it it revs really fast the next time or two.

  • scottrm1971 Jun 25, 2009

    I have asked several people what the black wire is going to but no one can tell me this. If I knew myself then I would be able to fix the problem more easily. Does anyone know what the other end of this mysterious black wire goes to????

  • scottrm1971 Jul 07, 2009

    HEEMAN453, where is this idle speed control unit located??? Whatever is making the engine flood when I first start the engine seems to be getting worse. It is getting hard to start but once it runs for about a minute it smooths out perfectly.... someone please help me.

  • scottrm1971 Jul 07, 2009

    I don't think that it is an injector problem cause after it warms up it runs perfectly. No misses, hesitations, or anything. It also idles down on its own so it can't be the idle sticking. It seems more like it is cold idle or choke related.

At the battery bracket/fuse box check those fuses with a test light

There's a magnetic coil in there, so it stands to reason it would get a bit warm.

    Many things can cause the stalling you described. Have
    you had a tune up lately? You may have a sticking idle speed control motor, a faulty
    EGR valve, a faulty fuel pump, a lock-up converter in the transmission not unlocking
    (if automatic) to name the usual suspects.

    heck to see what the clamped off vacuum hose is attached
    to. If it goes to the power brake booster, you may have a faulty power brake booster.

    heck to see what the clamped off vacuum hose is attached

    Check the
    ECC relay in the main power block; it is brown and black in color. This could
    be the cause of your no start problem.

    If a major tune-up has not been done recently, this could be
    the cause of your problem. Replace the spark plugs, plug wires, fuel and air filters,
    etc. Also, replace the oxygen sensor and multi-rib belt. In addition, service the
    fuel injection system. Clean the carbon deposits from the throttle bore and idle
    passages. If the problem still exists, scan computer for trouble codes.

Well it looks like there might be a couple problems here 1st one is it seems to be that there is a short in the wiriong harnest some where that is causing the wire to heat up the only way to fix that your self is to locate the short if not able to locate it find full service garage....

2nd if the vehicle keeps flooding it might be a fuel injection problem or stuck throttle try to look into that that is a easy find if its the throttle stuck you look under the hood for the throttle body which will have cables running to it and make sure it isnt stuck open...

is there ant thing else i can assist you with

European Cars follow the same wiring codes for their vehicle. The black wire if I am not mistaken is the one connected to terminal 15 or the switch controlled positive downstream - from the batttery. This means any electrical unit that needs only to be turned on when the key is switched, that wire supplies the power.

When your motor starts racing like you say shut it off asap.pull the fuse and check out. the fuse should be to the left of the steering wheel underthe dash .black wire goes to the negative end of the battery.if the black wire is looose or not connected or has cut in between the motor will get hot and make noises while starting.that wire is for giving pressure from battery to motor.if the black wire is not connected the motor will not start from the current of battery but by the force of the engine and it gets hot.check out the wire by meter.or get get it checked and connected by local car garage mechanic.this will help.

Normally if a wire gets hot then it means that the wire is not big enough for the current going through it,but now the problem is how hot is it getting? If you could find out where this wire goes then maybe I could help you more..Also there is an idle speed control unit which sometimes gets dirt clogged to it and a bit of cleaning normally sorts this out.I would suggest you clean the carb(if it has one) and use something called Reddex which cleans the whole fuel flow from the tank up to the combustion chamber...Hope this helps..

If the wire does not make any problem to the normal working of the engine and system ,don't get bothered about it.avoid the touching on the wire with bare hands.the hot you feel is normal and don't get scared of that.thank you

Are the battery connections dirty at all or any corrosion? A lot of vehicles idle at a higher rpm when they are first started and the idle will drop when they warm up. Is the vehicle engine light or any other light coming on? How old is the battery? How many miles are on the vehicle and when was the last tuneup? Could be as simple as your throttle body needs cleaning. Also is this a Gas or Diesel beetle? Once I have more information I can assist you even further. It sounds like general cleaning and maintenance should solve this problem. Also please give me a chance to assist you further before requesting for more help. Also at anytime you feel acceptable please rate my solution accordingly. Thank you,
Lee

    When was the last time you had a tune up? Also how many miles are on the vehicle? If you don't hit the gas pedal the vehicle doesn't start? Its possible it has something to do with the ignition. Would still like a little more information before I just start throwing things out there.
    Thank you,

High low idle, rough idle stalling


If it's surging, make sure your radiator is full. Do a tune up, plugs, wires, etc. Put some fuel injector cleaner in your fuel tank. On a cold start the vehicle compensates for being cold by adding fuel. Once it warms up the computer tells it to quit adding extra fuel. If it is a bad sensor of sorts, check engine light should come on.

Have the 'Throttle' or 'Accelerator' re learn performed. Some will re learn as follows : Turn ignition to RUN with engine OFF. Push throttle pedal to the floor and hold it there for 30 seconds.

Turn ignition off and then release throttle. Start engine and allow it to idle until warm ( 80C.) Do not rev the engine or put it in gear dueing warm up. It must be allowed to warm up at idle only. When you hear the radiator fan come on, turn engine off. Wait 10 seconds and restart engine. Test drive.

This procedure MAY have caused the throttle to relearn. If the same problem is present, go to dealer or VW shop and have them 'relearn' the throttle with a scanner.

Due to the amount of miles on it I would check the cat and the muffler to see if the exhaust is plugging up. It sounds like the engine is flooding and that is why you are seeing the black smoke when you rev it up. I would also check the ETC switch (it looks like a temp. sw) it sends a signal to the computer as to the outside temp and the amount of fuel need to fire the engine on start up until the idle air control kicks out.

Could be a idle air problem. The injector could be leaking when you shut it off ..Try some injector cleaner see if it gets better..The idle air shouldnt run rough just idle real low or sometimes it will get stuck and idle high....Are you losing any antifreeze..If you are the 2.0 SOHC engine bad about leaking antifreeze into the cylinder and makes the engine run rough until it burns it out..See if you can see the smoke coming out when it happens..White smoke indicates antifreeze,,Black smoke indicates fuel..

Error code po0117. Vw beetle


16501/P0117 - Engine Coolant Temperature Sensor (G62): Signal too Low Possible Symptoms
  • Difficulties with starting a cold engine.
  • Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
  • RPM at idle is irregular.
  • With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
  • With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
  • Bad acceleration during warming up.
    • Diesel: an indication is extreme long time burning time of the glow indication light.
Possible Causes
  • The electrical signal coming from G62 is too low
  • Wiring and/or connections faulty (short circuit?)
  • Engine Coolant Temperature Sensor (G62) faulty
Possible Solutions
  • Check wiring and connections
  • Check / Replace Engine Coolant Temperature Sensor (G62)
Special Notes
  • In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.

Engine shakes and hesitate when started until it idles down


Sounds like its missing on 1 or more cylinders. A check of the plugs and wires is in order, Could be a fouled plug or a loose/bad sparkplug wire. Best of luck.

Idles high when warm


With the age of the vehical it might be a good idea to do a compression test first. I would check the timing. Sounds like the engine is advancing for some reason, if that checks out then recheck for vacuum leaks( it could be leaking past the base gasket, vacuum booster, or intake), The vehicle has a carb. not a throttle body injection? Also if you can retrieve that engine code it may be helpful.
