16 yr old daughter has a blond attack - Help

Just towed the car home yesterday..

Probable cause... $10 worth of Diesel fuel in a 1.8T.

Yea.. I know. Thought everyone might get a good chuckle and have a "glad it's not me thought".

The car died in a mall parking lot down the street from the gas station. I suspected it was starving for gas when I tried to start it as it would occasionally fire but not start. I changed the fuel filter (in the parking lot). Still didn't start so I had it towed home. Got back home a poured the remaining fuel out of the old filter into a glass. Didn't look or smell right. Called the gas station this morning to ask if there were any other complaints. Told her what time of day and which pump my daughter used to fuel. She was very nice, took down my info and said she would have the owner call me back. Then a few minutes later, she calls and says "sir, pump #2 is diesel fuel"....

The tank was low when she fueled it so I'm guessing the mix is probably around 4 to 1.

I appreciate it if someone could pass on a procedure to flush the fuel system.

I do have Ross-Tech Vag-Com and a Bentley manual.
I'm assuming I may need Vag-Com to turn on the fuel pump and/or injectors at some point..

so the mix is 4 to 1, diesel fuel being in there 4 times more than gasoline? If your tank is low enough, it is possible to fill it up with premium gas and it may start. Diesel fuel shouldn't KILL the engine, it just doesn't spark, so you should be able to burn it out. As for flushing it out, the only thing I can think of is to remove the gas tank from the car and empty it.

:hmmm: I've burned diesel in a gasoline engine before (mind you it was shit and being thrown out in the near future). It should run really rough but it still should run. But on the other hand, if that was my car I wouldn't run it with the diesel either. Carbon like you wouldn't believe. My best advice would be to fill the tank full with normal gasoline (preferably 91) and burn it all off. Next tank throw in a bottle of fuel injector cleaner. You wont even notice the diesel. Good luck.:salute:

Maybe pay someone to siphon it out... (j/k... don't actually let someone do it.. health problems etc..) except if its the dealer.

Seriously, maybe try those manual pumps from the auto store and try to flush out as much as you can... there might be a liter or so remaining in the system but tilt the front end of the car and let gravity do the rest. Pump out remaining fuel then put regular (premium) gas.

Health issues? I remember watching Mel Gibson in Lethal Weapon sucking gas out of a gas tank with his mouth, then spitting it on the ground and muttering "...Exxon." I've done the same myself more than once, though I generally try to avoid completing the siphon before the catch-can is in place.

Come on guys, it's not that big a deal. Siphon the stuff out and use it to run a chainsaw or an old lawnmower or something.

You could just pull out the fuel pump in the trunk and siphon straight from the tank, no?

doh, too slow

you don't need to remove the gas tank to empty it, but removing the fuel pump assembly will give you greater access to the tank to pump it out.

Here is what I would do:

-Remove the fuel pump, drain the tank COMPLETELY, wiping it dry even.
-Reinstall the fuel pump. Disconnect the fuel return line (it'll be obvious when you look at the pump assembly) and run it into a container with a longer hose.
-Run the fuel pump until nothing comes out. You can do this by cycling the key to off-on for 2-3 seconds at a time. It won't take too many cycles.
-Change the fuel filter, and reconnect all hoses.
-Fill the tank with premium gas, completely.
-Prime the fuel system with the same cycle method as for the drain.
-Start the car. It might take a little work, but it will start.

I doubt diesel will do much harm to the car. I use diesel to clean and store fuel parts. The gasoline will wash it right off.

Your biggest problem will be disposing of the mess. It's dangerous and considered hazmat. Check with your town on what to do.

Be very careful working around fuel. No sparks, no fire. Keep an extinguisher handy, and have someone supervising or within earshot.

For the record my old Mercedes 300SD owner's manual said you can use gasoline in a diesel as an emergency fuel. The cetane/octane rating of gasoline is much lower than gasoline so power is considerably reduced.

Truckers use gasoline in their diesel in the winter time to keep it from gelling. Anytime you are following a diesel in the cold winter at night and you see a blue flame coming from the stack, that's gasoline continuing to burn as it is being exhausted.

#2 Diesel is virtually the same as jet fuel and home heating oil.
#1 Diesel is the same as #2 diesel with an anti-gel additive which could be gasoline.

Diesel fuel won't hurt anything. Siphon as much as you can out and refill the tank with gasoline. The diluted mixture will be just like adding top lube to your fuel. In about 300 miles all will be OK and you can reset any engine codes you might get.

Harbor freight and tools sells a siphon for pretty cheap. I hear it works good.

Last year i was frantically trying to get back to my house on my Harley. Pulled up to a station...grabbed the far right pump and started filing. Realized about .0001 miles up the road what I had done, full tank of diesel. Now I was stranded. A buddy of mine came over and we siphoned it out with a cut garden hose (we were both puking in front of my house). Filled it up with some premium . Ran like crap till I blew out all of the deisel.

I feel your pain for my 17 year old had a blond moment last summer going thru a drive-thru in the rain. She side-swiped the cement pole protecting the pick-up window area trying to stay close so she wouldn't get wet under a huge overhang :banghead:. She did it at night and I leave for work early AM and didn't notice it in the dark. I saw it in the parking lot at work as I approached my car while leaving work WTF!! So much for my cars pristine body :mad:. Doesn't affect operation and I didn't want the hit on my deductible and insurance premiums. The Joys of fatherhood.
Reading all the responses, it looks like you're gonna be ok - I hope it goes well for you.
OH YEAH, for the posters that want responsible fathers to post pictures of their beloved daughters (I don't care how many blond moments she has with my car) for all the world to see - AIN'T GONNA HAPPEN.

I would second the siphoning from the fuel pump hole.
you would be able to siphon about 99% of the fuel.
open the fuel line just before the injector rail.
fill some premium in the tank and cycle a few time the pump to clean out the lines.
after it should be able to start and run it for a while.

not sure about the passats, but most cars the fuel pump is under the seat. hook a rubber hose to the output, wire up the motor, and let the sucker pump itself out.

guess yall need to learn how to siphon. ive siphoned diesel plenty of times and got a drink once. never happened again :icon_eek:

Maybe, just maybe, she was trying to be nice and save money by fueling the cheapest one around. She is just 16, life is a good teacher, she will know better the next time.

^^

Magic? :rolleyes: but as many have mentioned, I’m sure she's chalking it up as an embarrassing moment and for young girls that’s a big deal. She’ll remember next time i'm sure. ..*fingers crossed*

Sorry to hear about your misfortunes though...at least she was paying for her own gas! :thumbup:

I would get all the fuel out from the pump assembly location, as pet CTOBIO's instructions, but no need to wipe it dry, though. Don't forget to change your fuel filter again, and purge the fuel line, pressure regulator, and injector rail. (don't know the exact procedure, but google is your best friend)

After all that, just before trying to start the engine I would completely remove the coil packs from the vehicle (to prevent unwanted sparks ANYWHERE), remove all sparkplugs, disconnect (electrically) fuel injectors, and crank it up a few seconds, as to get any flooded diesel out of the cylinders. Do it in a well ventilated area away from people, as you might get them sprayed. Don't put anything near the spark plug holes (like a rag or something) while doing this as it might get sucked it. (someone else's fingers included...)

Reinstall spark plugs and coil packs, reconnect fuel injectors, reset ECU, and fire away.
