Unhappy Blinking Fuel Gauge Lights '98 SL500

Has anyone experienced their fuel gauge lights blinking? They blink continuously, then stop without warning.

Thanks for any suggestions.

Do you mean the instrument back light or the fuel gauge warning lights? If the first, there may be a loose connection in the instrument panel, or a loose bulb, easy to fix once you get the instrument panel out but that is difficult to do without the right tool to avoid damaging the surround.

If it's the low level light, check the fuel sender connections which are under the rear seat. It may be you would need a new fuel sender, not a job to do at home.

Thanks for the info. Both lights blink, Iwas hoping it was something simple I could repair myself.

Sorry for bringing back an old thread,

Your thoughts? I have checked and replaced all the vacuum lines and fuel cap. What else?

The regular flashing discounts a loose connection and I think it may be linked to the check engine light. I think itís time to take the car to an MB specialist who can read out the diagnostics and has a manual explaining what the flashing means. It might, for example, mean the fuel pump pressure is low. These are old cars now and without modern displays, different light patterns could have been used to aid diagnosis.

The flashing indicates a leak in the EVAP system, though it's possible there is no leak at all, and a sensor is malfunctioning. Reading the OBD-II code associated with the Check Engine light may provide further detail.

Plugged it in and checked the faults.
Bad MASS and EGR valve.

Replaced both and so far so good.

If your mechanic thought the air flow sensor or the EGR valve could cause an EVAP code, then I would look for another mechanic.

Actually, I'm pissed off cause he's an Indy mechanic and he's doing exactly what dumb f**k dealerships do!
Plug in the Star diagnostics, and replace exactly what that stupid machine tells yo to, reset the codes, take it for a 3 min test drive and deliver to customer!

I'm going back and finding out what's going on cause yesterday he sent me a message saying they are looking for a "Fuel Pressure Sensor"

Apparently he is not doing that.

Here is the diagnostic manual for your engine: http://manual.startekinfo.com/manual/JSP/e4/9_4/m11.jsp. There are several codes associated with the EVAP system, and none of them encompass a diagnostic outcome where replacing the air mass sensor or an EGR component is indicated.

Thank you so much sir, much appreciated.
I'm gonna tackle this issue myself.

On a side note, I previously purchased an Actron CP9690 Elite AutoScanner Kit Enhanced OBD I and OBD II Scan Tool for all 1996 and newer and select 1984-95 vehicles.
I needed this for my 1993 Dodge viper RT/10.

Can I use this device on my 99 R129?
