Has anyone had any issues with their car stalling after fueling up? The first time I thought maybe I was just really low on gas, but since then I've had it happen when filling from half full. Any ideas on what causes this?

 

Mine does the same thing... From what I understand it's a common issue but I don't know what the fix is. Trying to figure that out myself!

 

Could be fuel EVAP system. Next time try filling up 3/4 of a tank instead of completely full see if that might help.

 

filler cap issue . . . it is not sealing correctly

clean the seat and the gasket .... I'll bet there is some crud in there

 

Thanks for the tip Capt bj, unfortunately I cleaned it out but there wasn't anything in there. The interesting thing is that I tried starting the car after having the cap open for cleaning and though the engine didn't die, it was very close. Letting it idle for a minute brought it back. But just opening the cap seems to be all that's needed to cause a problem.

 

EVAP problem. Check the Fuel Tank vent valve and/or scavenger line extension.

I would agree 100%. This is a common charcoal canister issue for any car, not just MINI's. When the gas tank is filling fuel vapors start to build up. Ever since early 90's or so EPA standards have mandated an evaporative emissions control system installed in every car. This is because when fuel evaporates (that strong gas smell is the vapor) it goes into the air and atmosphere as pure hydrocarbons which have a direct effect on greenhouse gas pollution which is known to destroy the ozone. This is also why our cars have catalytic converters in the exhaust, so hydrocarbons can be converted to carbon monoxide and carbon dioxide and water vapor.

So anyways... what happens is that there is a vent line near the top of your tank which those fuel vapors are supposed to collect and go through that vent line into the charcoal canister. The charcoal canister then absorbs the fuel vapor which collects instead of venting into the atmosphere. Your evap purge valve then opens to utilize the vacuum from the engine intake to suck this fuel vapor into the engine to burn in your combustion process.


In your case, if you top off then engine after the nozzle automatically shuts off or if you have an issue with the fuel vent valve or evap purge system, pure liquid gas ends up filling up your charcoal canister which in turn ends up flooding your engine and causing the stalling.

If you happen to be one of the *many* people who 'top off their engine' I would kick that habit immediately as this is the pure evidence of what will happen from not allowing an air pocket at the top of the tank for the evap system to properly breathe.

So what do you do to fix this problem if the eng light has come on and gave this code? Any help is appreciated.
