Simple solution is keep the tank full. What you are seeing is caused by the "free surface effect" (gasoline sloshing back and forth in your tank). If you can't keep your tank full. learn to ignore it or put black tape over it. The repair will be very expensive.

Thanks for your question @ FixYa.com

    Wat is the repair gna cost I don't mind the cost and wat is it

  • A Miller Aug 04, 2011

    If you don't mind the cost, go into your Jetta VW dealership and have it done. It takes about 4 hours ... I don't know what country you are in so I can't quote you a price as such ... I am neither a mechanic in a auto shop nor am I a dealer. On the US Eastern Seaboard, shop time is about $100.00 per hour and I would expect parts to be about $100.00 when all was said and done, if it is repairable and doesn't require other repair parts. I suggest you call around and find out the "flat rate" time for this job is and you can come up with your own estimate in your community based on the local shop rates.

    According to Kelly Blue Book, a car similar to yours is worth about $1,150.00

    The most recent fuel tank experience I had was estimated to be way more than $500.00 because the fuel tank foundation was wasted (and would require rebuilding of the trunk and foundation for the tank). I had to junk the car, which was a '95 model year (not a VW). I have done this proceedure (dropped the tank) several times for myself on an assortment of vehicles and based upon my experience, I am giving you the original advice of leave it alone. Frankly my friend, I wouldn't invest more than 10% of the value of the car in repairs of this nature.

    Thank you for your question and feedback @ FixYa.com

Fuel gauge does no register properly

Older cars use to fluctuate, when driving. Not at start up. At start up it would be a power or ground problem. Newer ones can also be power and ground. They don't fluctuate though. I have found that newer cars that fluctuate are a problem with the instrument panel(IP). The different readings at start up could be the IP or the sending unit in the tank

I have a 1992 Mercury Grand Marquis Ls with a fuel gauge that does not work (gauge may be reversed)??? help please.

The fuel level indicating system is a magnetic type system, which consists of the sending unit located in the fuel tank, an anti-slosh module located on the back of the instrument cluster, and a fuel gauge located in the instrument cluster. The sending unit changes resistance according to the level of fuel in the fuel tank, which varies the current flow through the gauge.The pointer position varies proportionately to the current flow. In this system, the sending unit resistance is low (22 ohms) when the fuel level is low and high( 145 ohms) when the fuel level is high. The pointer of the magnetic gauge remains in position when the ignition is turned to the Off position. On some models, an anti-slosh module is used to dampen out fluctuating fuel signals from the sender. Some vehicles are equipped with a low fuel warning indicator. The anti-slosh module will also actuate the low fuel indicator when the fuel level in the tank reaches 1/16 to 1/8 full.


Do your other gauges/warning indicators work properly with the ignition on? If not, check for power at the fuse panel/fuses.

If they do then partially remove your cluster with connector still installed and check for voltage at cluster connector and gauge. Check continuity of cluster and gauge for ground.

Sometimes the anti-slosh module (if installed) goes bad in the Grand Marquis but not likely.

Sender troubleshooting:
  1. Perform test with resistors as follows:
    1. Disconnect wiring connector at sender unit, then connect resistor between gauge lead and a suitable ground.
    2. Turn ignition switch to On position.
    3. With 145 ohm resistor, the gauge pointer should contact the Full mark.
    4. With 22 ohm resistor, the gauge pointer should contact the Empty mark.
  1. Perform test with fuel sender of known quality as follows:
    1. Turn ignition to Off position.
    2. Disconnect wiring connector from sender and connect it to test sender.
    3. Move float rod away from fuel filter against Full stop position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or above the Full mark.
    4. Move float rod toward fuel filter against Empty stop position. Turn ignition switch to Off position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or below the Empty mark. If gauge works properly replace sender, which involves dropping fuel tank.

Hi I just bought an 51 plate Audi A4 1.9 tdi b6 model. The speedometer does not work and is constantly on zero and the fuel gauge fluctuates while driving. Also the odometer is stuck on 123122 miles. Any...

Have the speed sensor checked, that's mounted on the side of the tranny, that operates the speedometer. As far as the fuel gauge, probably the fuel sending unit is shot which is in the gas tank.

Fuel gauge peggs out

Mostly likely you have a tank mounted fuel gauge. If your vehicle is pointing down hill the guage goes up or down. It is usually the fuel level in the tank that makes the float go up to tell you how full the tank is, if fuel is sloshing around then level fluctuates. I would say that if it stabilizes on level ground and at a stop, and you can get a stable fuel reading then this is more of an annoyance than a problem. If you can get an accurate reading and you do not run out of fuel you may want to leave this one alone, you will have to drop the fuel tank and replace the fuel float on top of the gas tank which can be labor intensive as well as expensive.

Fuel box licking

vent valve or vapor canister purge valve is what I believe your referring too. You dont need to replace the complete vapor canister, just the valve itself. the valve is connected to the canister with a small 2" long rubber hose.
