Stolen Gas Cap....

[Cliff_W140]

1999 E430

Yesterday morning I walk out to my car and notice that my fuel filler door has been pried open, my gas cap is missing, and my tank has been siphoned empty (same story for the cars on the left and right of me.)

I ordered a new cap from fastline and filled my tank using only a rag until the new cap arrives.

Tonight while driving home from work I noticed that my low fuel warning lamp on the gauge was blinking and the check engine light was on. Got out and fiddled with the gas rag and the light quit blinking but Check Engine remains on. Am I correct in assuming that the Check Engine light is a result of no filler cap? The new one should be arriving any day now.

Thanks,
Cliff
