Audi Fuel Drain


Putting Petrol in a Diesel Audi is a common mistake. And its solution hinges on an assortment of factors. In the event that you want to know what you ought to do to sort it out then please read on.
Right here are the most crucial variables to be aware of whenever determining whether to get it drained:

  1. How much Petrol have you put in the Audi, considering that the fuel tank capacity of your Audi A3 TDI is in most cases roughly 55 litres?
    1. A tiny amount of Petrol, less than 2.75 litres of Petrol in a Diesel A3 TDI will typically not be a huge problem. Experience has proven to us that anything less than 2.75 litres (almost 5% of the whole fuel tank volume) is quite often able to be adequately diluted by totally filling the tank with the appropriate fuel.
      It's very rare to come across a car or truck experiencing issues due to below 5% incorrect fuel contamination. Please remember it is infrequently found - certainly not impossible to find. There are a few automobiles that will not stand any amount of fuel contamination at all.
    2. Between 2.75 and 5.5 litres of Petrol in the Audi (from 5 to 10%) is a 50/50 condition. Our working experience has demonstrated that as many motorists get away with it as those who don't. When you are trying to decide whether to chance it and just top it up remember that it is exactly like betting all of it on black - you will have a 50/50 chance of it working.
    3. Anything over 5.5 litres of Petrol in your Diesel A3 TDI should straightaway be removed since your likelihood of driving with that quantity of contamination is probably less than one in fifty - truly huge odds.
  2. Put some Petrol in a Diesel Audi and drove it: Have you seen any kind of performance concerns since putting the bad fuel in the A3 TDI? If you have, get it emptied no matter the amount of Petrol or the contamination ratio. Continually driving an automobile that is currently beginning to suffer from the consequences of fuel contamination can just be responsible for increasing amounts of harm affecting your fuel system components.
  3. Would you like peace of mind?
    Simply get it emptied. Whatever the contamination percentage, there is always a certain level of risk connected to operating a Diesel vehicle on Diesel contaminated with the incorrect fuel. Likely implications of driving a car on the incorrect fuel can include the engine refusing to start, running lumpy, loss in power, degradation of the high-pressure pump, worn out or clogged injectors, and the like. These are a few of the most common Petrol in Diesel signs or symptoms, and if you recognise any of them then stop driving and get it removed right away.

Petrol in Diesel FAQs

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?


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?


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?


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 Diesel 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.
