C230 K 2000 Blinking Fuel indicator...
 

Just bought a 2000 C 230 K with 139, 000 KM on it. Very clean and excellent drive. The fuel warning light keeps lighting up and does not go away untill I shut engine down and restart later. I checked the tightness of the fuel filler cap , because the manual reads that a lose fuel cap could cause the blinking. Well I dont think it is. Also, almost everytime the fuel light comes on the "Check Engine" light also comes on.

Also between 100km/hr to 130km/hr the car has a vibration which goes away if I exceed 130km/hr or drop below 100km/hr. I checked the PSI in all tires, left rear was short a few PSI. I didnt test yet but I am just putting this info out.

I checked the oil, its slightly below max marking.

Should I have this diagnosed at a shop? Any hints?

thx for that link.

Is the Fuel shut off valve, AMM or MAF covered as part of engine warranty?

I have powertrain warranty on the car. I have only had it for five days, I am going to have this problem diagnosed but its comforting that its not difficult to fix on my own.

it depends on rhe warranty company you chose, some may some may not

UPDATE.


I took the car to a shop downtown (non mb but they have a lot of euro cars go through), had the guy hook up the diagnostic reader. He pulled a code P0455. Evap/Emissions Leak. Which he said could be the gas cap, before I mentioned it. I then tried a cap from a 1997 c230 and drove for about 15 minuets, till the fuel indicator light came on again, but the Check Engine light did not come on. I went back put my original cap on and drove for about 7 minuets when both fuel indicator and Check Engine lights came on. I then got home and put the cap on from my 190e 1990 2.6L. Same result, no Check Engine light but fuel indicator light came on.

I have question about gas caps. I was browsing ********AZ and saw that Gas Cap for 2000 C230K costs about $15 more than a Gas Cap for a 190e 2.6L, while both seem to intergchangable. Are they the same?
