gas in my sportwagen

I put about 3 gallons of gas in my sport wagon yesterday. it had over half a tank of diesel when I did it. I'm wondering if I can get away with adding a couple quarts of 2 cycle oil and topping it off with diesel fuel.

definitely not. Do not start your car. Have it towed to a dealer. They will drain your fuel tank. you have some expensive components that will fail if you run rug through you fuel system.

I would agree with axnels2, have it towed and flushed

Yeah, take something that is bad for your fuel system and compound it by adding something that is potentially bad for your emissions system. This is not your father's diesel engine. Do not start the engine. The more gasoline that hits your HPFP the more damage will be done. A failed HPFP can require replacing the entire fuel system from tank to injectors ($$$$). Tow it to a shop, flush the whole fuel system, and hope for the best.

Have Fun!

(Read: $10k plus bill sometimes). Tow it.

how were you able to do this with the tank inlet guard?

'12s didn't come with the inlet guard, it was added later. I've avoided getting one, and maybe the OP has, too.

To reinforce what others here have said, DO NOT drive the car. Have it towed to a dealer and flushed out. Be sure the tow truck driver and dealer staff know not to start it. Personally I'd not leave its side until it's in the service bay.

So OP... what did you do?

Dead easy fix, they have an in tank fuel pump disconnect the fuel hose at the filter and pump it out while bridging the fuel pump relay, had to do it many times at work and once at my parents. Replace the fuel filter, fill with diesel and done. It happens a lot more then people think. Use the old fuel for the lawnmower (cut it with more gas), starting outdoor camp fires etc. No sense disposing of it fuel is fuel. I run it in our old Mercedes diesel when it happens, they could handle up to 25% gas as written in the manual. Gas does clean out a diesel engine very well, problem is the high pressure pumps on modern stuff cannot tolerate the dryness.

It might be a "dead easy" fix on your 2000 TDI but the OP has a 2012 CR engine. The fuel system (particularly the HPFP) is far more fragile than anything on your car. With a CR engine the tank must be drained, the fuel lines flushed, the fuel filter replaced, and probably a few other things. Plus, you have to worry about how much damage might have been done to the HPFP. Poor lubricity fuel can (and will) seriously shorten the lifespan of these pumps. It is impossible to know if any (or how much) damage occurred without completely disassembling the pump (with I do not recommend).

Have Fun!

I have the fuel guard on mine and cant even tell its on their, maybe the BMW system is different for fuel guards...

Old tdis have no intank pump, it is NOT easy to drain the tank on them, starting in 2004 they added in tank pumps so you can pump out your bad fuel. I have had to fix several Mercedes Benz CDand Jeep GC CRD with gas pumped into them, zero damage in every case and all common rail engines, they drove in misfires and we pumped them dry and changed the filter and still around. One Jeep it happened twice that I was around on the same car...it was up to almost 200k miles at that point.
If you pump the fuel out you are really flushing the feed line, what the return system holds is going to be very small % in the end. Swapping filters takes the rest out, be sure to empty the filter canister of fuel too. Just because a dealer writes out a long winded service order doesn't mean they actually do all those steps, ask me how I know I worked there for years. Adding a good dose of fuel conditioner/lube is always a good thing after an event like this, not a cleaner but conditioner.

As others have stated, how the heck were you able to get the nossel in with the fuel guard? And if there isn't one there, why didn't you take it in for the recall or the dealer do it during routine service? I know it was a mistake, but if you ran the motor, you could be in for some big repair bills. Hopefully not...good luck.

There is no need to do all that if you don't turn the ignition on. You just simply drain the tank and refill it. In fact....I definitely would not take it to a dealer to do this. They will document it as a mis-fuel and definitely void their unofficial extended warranty of HPFP's.

Donald

VW has been covering HPFP failures even when owners have admitted a mis-fuel......

If you attempted to drive it... you may have just voided your drivetrain warantee. Longstanding significant issue with CR TDI fuel system and incompatibility with gasoline. I hope you didn't tell your dealership that you drove it after putting gasoline in it

May not help if the gasoline is in the injectors by now.

Gotta wonder if the OP is pulling our collective leg. This is his (or her) only post on the forum, and not a single response in over two weeks to the replies of forum members.

Just doesn't want to admit he/she started it up...
