Audi Fuel Drain

ABOUT

Filling up with Diesel in a Petrol Audi is a regularly occurring mistake to make. And its solution varies according to a variety of things. In the event that you want to find out what you must do to sort it out then stay with me.
Listed here are the most important factors to keep in mind when making a decision whether to have a fuel drain:

  1. Exactly how much Diesel have you put into the Audi, considering that the fuel tank capacity of the Audi A4 Quattro is probably around 60 litres?
    1. Hardly any Diesel, less than 3 litres of Diesel in a Petrol A4 Quattro will in most cases not really be a big problem. Experience has demonstrated to us that quantities under 3 litres (which is 5% of the entire fuel tank capacity) is frequently capable of being sufficiently diluted through entirely topping the rest of the tank with Petrol.
      It is relatively rare to find a vehicle having difficulties due to less than 5% wrong fuel contamination. Please remember it's infrequent - certainly not impossible to encounter. There are actually certain motor vehicles that won't stand any amount of contamination in the slightest.
    2. Anywhere between 3 and 6 litres of Diesel in the Audi (5 to 10%) is a 50/50 scenario. Our expertise has proven that as many people get away with this as those who don't. Whenever you are trying to decide whether or not to chance it and simply top it up bear in mind that it is exactly like wagering your car on black - you have a 50/50 chance of it working.
    3. Anything in excess of 6 litres of Diesel in a Petrol A4 Quattro should straightaway be removed seeing that your likelihood of driving with this amount of contamination is undoubtedly lower than one in 50 - really big odds.
  2. Put Diesel in a Petrol Audi and drove it: Have you detected any performance troubles since putting the wrong fuel in your A4 Quattro? If that's the case, get it drained no matter the volume of Diesel or the contamination percentage. Proceeding to drive running an automobile that is currently beginning to suffer from the consequences of wrong fuel contamination will typically end up in more harm affecting the fuel system components.
  3. Do you need security?
    Simply get it removed. Regardless of the contamination ratio, there is always some amount of danger connected with operating a Petrol engine on Petrol contaminated with Diesel. Probable implications of driving on the wrong fuel normally include the engine refusing to start, running unevenly, loss of power, wearing of the high-pressure pump, damaged or blocked injectors, and the like. These are a few of the most typical Diesel in Petrol symptoms, and should you notice any of them stop driving and get it removed right now.

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?

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 Petrol car on Diesel 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 Diesel can I get away with in a Petrol 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 Petrol 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.
