Fuel gauge flutter....Normal??
I noticed tonight that when my needle was between 1/4 and R that at stops it would jump back and forth. Is this normal or is there a voltage regulator in that circuit that might be going bad? I know on older domestic cars that the guages stayed steady with the help of a regulator. After filling up it does not flutter. BTW car is a 92 W124.
Thanks.
Thanks.

Your symptoms sound similar to a problem common to Audi/VW cars.

Hopefully, it's as simple as this. Let us know. . .

Replace the fuel gauge sensor in the tank. It is behind the carpet lining in the trunck. Open the large hex nut and pull the sensor (6-7 inches long) and replace it with a new one (approx. $ 20). It should fix the needle to jump up and down.
I just checked another source concerning the flattering gauge. It can also be a cold solder joint at the back of the fuel indicator instrument itself.
