Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a very common error. And exactly what you should do about it is based on a few things. If perhaps you want to know what you need to do to sort it out then keep reading.
Listed here are the key variables to take into consideration whenever determining whether or not to get a fuel drain:

  1. Exactly how much Diesel have you put into the Audi, bearing in mind that the fuel tank capacity of your Audi RS Q3 is usually approximately 64 litres?
    1. A tiny amount of Diesel, as little as 3.2 litres of Diesel in a Petrol RS Q3 will normally not be a massive problem. Experience has demonstrated to us that an amount less than 3.2 litres (which is close to 5% of the total fuel tank volume) is frequently capable of being adequately diluted simply by wholly topping up the tank with Petrol.
      It's pretty uncommon to encounter an automobile going through issues with lower than 5% wrong fuel contamination. Remember that it is unusual - in no way impossible to encounter. You will discover a few vehicles that will not stand any amount of fuel contamination whatsoever.
    2. Anywhere between 3.2 and 6.4 litres of Diesel in the Audi (from 5 to 10%) is really a 50/50 condition. Our working experience has proven that as many people get away with it as those who don't. Whenever you are deciding on whether to chance it and just top it up recognise that it is just like gambling your car on black - you have got a 50/50 possibility of it being ok.
    3. Anything over 6.4 litres of Diesel in a Petrol RS Q3 really should as soon as possible be removed because your likelihood of succeeding with this level of contamination is undoubtedly lower than one in fifty - truly long odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you spotted any performance issues after putting the bad fuel in the RS Q3? If so, have it emptied regardless of the volume of Diesel or even the contamination percentage. Continually running a vehicle that is currently beginning to suffer from the consequences of fuel contamination can definitely end up in progressively more harm affecting the fuel system parts.
  3. Do you need assurance?
    Then get it removed. No matter the contamination percentage, there is always some amount of risk in connection with driving a Petrol vehicle on fuel contaminated with Diesel. Likely outcomes of driving on the incorrect fuel include things like the engine refusing to start, running lumpy, loss of power, degradation of the high-pressure pump, worn out or blocked injectors, etc. These are some of the most common Diesel in Petrol warning signs, and should you observe any of them cease driving and have it drained asap.

Diesel in Petrol FAQs

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

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


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 Petrol car on Diesel cause damage to it?


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 Diesel can I get away with in a Petrol car?


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?


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?


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 Petrol and add some 2-stroke oil?


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.
