Audi Fuel Drain

ABOUT

Filling Petrol in a Diesel Audi is a common problem. And its solution is determined by several different factors. If you would like to find out what to do about it then continue reading.
Right here are the most crucial variables to take into account when deciding on whether to get a fuel drain:

  1. How much Petrol have you put in to the Audi, considering that the fuel capacity of your Audi A7 TDI is probably approximately 65 litres?
    1. A small amount of Petrol, as little as 3.25 litres of Petrol in a Diesel A7 TDI will in most situations not necessarily be a significant problem. Experience has taught us that an amount less than 3.25 litres (about 5% of the entire fuel tank volume) is generally able to be sufficiently diluted by thoroughly topping the tank with Diesel.
      It's extremely rare to encounter a car or truck going through difficulties with under 5% incorrect fuel contamination. Remember that it's rare - certainly not impossible to encounter. You can get certain vehicles that won't endure any amount of contamination in the slightest.
    2. Anywhere between 3.25 and 6.5 litres of Petrol in the Audi (from 5 to 10%) is really a 50/50 scenario. Our practical experience demonstrates that as many people get away with this as those who break down. Any time you're figuring out whether to chance it and just top it up remember that it is very much like betting it all on black - you will have a 50/50 possibility of it being ok.
    3. Anything over 6.5 litres of Petrol in a Diesel A7 TDI should right away be drained out seeing as your likelihood of driving with this quantity of contamination is undoubtedly below one in 50 - seriously huge odds.
  2. Put some Petrol in a Diesel Audi and drove it: Have you seen any performance issues ever since putting the bad fuel in the A7 TDI? In that case, have it emptied regardless of the volume of Petrol or even the contamination ratio. Still driving a vehicle that is currently beginning to suffer from the effect of wrong fuel contamination will probably typically bring about even more harm being caused to your fuel system components.
  3. Do you need peace of mind?
    In that case get it removed. Regardless of contamination percentage, there is inevitably some degree of threat linked with running a Diesel motor on fuel contaminated with Petrol. Possible final outcomes of driving on the incorrect fuel can include the engine not starting, running unevenly, losing power, degradation of the high-pressure pump, worn or blocked injectors, etc. These are several of the most frequently seen Petrol in Diesel symptoms, and should you observe any of them then stop and have it drained immediately.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?

Answer

Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Diesel car on Petrol cause damage to it?

Answer

It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Petrol can I get away with in a Diesel car?

Answer

The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?

Answer

Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?

Answer

No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Diesel and add some 2-stroke oil?

Answer

This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
