Audi Fuel Drain


Putting Petrol in a Diesel Audi is a regular mistake. And what you should do about it is determined by a number of things. Assuming you want to know what you have to do about it then keep reading.
Listed here the main variables to to consider whenever deciding whether to get it drained:

  1. What amount of Petrol have you put into the Audi, taking into consideration that the fuel capacity of the Audi A5 TDI Quattro is normally about 64 litres?
    1. A modest quantity of Petrol, something like 3.2 litres of Petrol in a Diesel A5 TDI Quattro will typically not be a massive problem. Experience has taught us that anything less than 3.2 litres (approximately 5% of the whole fuel tank capacity) is very often able to be sufficiently diluted by means of entirely filling the rest of the tank with the right fuel.
      It's highly rare to find a car or truck going through issues with less than 5% wrong fuel contamination. Remember that it is unusual - not impossible to encounter. There are actually certain motor vehicles that don't endure any amount of contamination whatsoever.
    2. Somewhere between 3.2 and 6.4 litres of Petrol in the Audi (from 5 to 10%) is really a 50/50 situation. Our practical experience has shown us that as many people get away with it as those people who don't. Any time you are trying to decide whether or not to risk it and simply fill it up remember that it is just like betting all of it on black - you have got a 50/50 chance of it working out.
    3. Anything in excess of 6.4 litres of Petrol in your Diesel A5 TDI Quattro ought to straight away be drained since your likelihood of getting away with that amount of contamination is very likely lower than one in 50 - genuinely huge odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you spotted any kind of performance issues ever since putting the incorrect fuel in the A5 TDI Quattro? If so, have it emptied irrespective of the quantity of Petrol or even the contamination ratio. Still driving a motor vehicle that is already beginning to suffer from the consequences of fuel contamination will just bring about even more harm affecting the fuel system.
  3. Would you like security?
    Then get it emptied. Regardless of contamination percentage, there is inevitably a certain level of danger associated with driving a Diesel motor on fuel contaminated with Petrol. Probable consequences of driving on the wrong fuel normally include the engine refusing to start, running lumpy, losing power, degradation of the high-pressure pump, damaged or clogged injectors, and so on. These are several of the most typical Petrol in Diesel symptoms, and should you notice any of them then stop and get it removed as soon as possible.

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.
