Audi Fuel Drain


Filling up with Diesel in a Petrol Audi is a fairly typical error. And exactly what you need to do about it depends upon a number of factors. In case you want to find out what to do about it then keep on reading.
Right here are the key factors to consider whenever determining whether to get your car drained:

  1. How much Diesel did you put in to the Audi, keeping in mind that the fuel capacity of your Audi A2 is usually roughly 34 litres?
    1. Hardly any Diesel, something like 1.7 litres of Diesel in a Petrol A2 will usually not really be a big problem. Experience has proven to us that anything less than 1.7 litres (approximately 5% of the fuel tank volume) is sometimes able to be completely diluted by entirely filling the tank with Petrol.
      It's relatively unusual to find a car or truck having difficulties because of below 5% incorrect fuel contamination. Please remember it is unusual - definitely not impossible to encounter. You will discover certain cars that don't stand any degree of fuel contamination whatsoever.
    2. Between 1.7 and 3.4 litres of Diesel in the Audi (from 5 to 10%) is really a 50/50 situation. Our expertise has proven that as many people get away with this as all those who don't. Whenever deciding upon whether or not to chance it and basically fill it up bear in mind that it is much like betting everything on black - you have a 50/50 possibility of it working out.
    3. Anything above 3.4 litres of Diesel in a Petrol A2 should really straight away be drained seeing that your probability of driving with that amount of contamination is almost certainly less than one in 50 - definitely long odds.
  2. Put some Diesel in a Petrol Audi and drove it: Have you noticed any kind of performance issues after putting the bad fuel in your A2? If that's the case, get it removed irrespective of the amount of Diesel or the contamination percentage. Still driving a car that is now beginning to suffer from the effect of wrong fuel contamination can typically be responsible for more harm affecting the fuel system parts.
  3. Would you like security?
    In that case get it removed. Regardless of the contamination percentage, there is always some extent of danger in connection with operating a Petrol engine on Petrol contaminated with the incorrect fuel. Likely outcomes of driving on the incorrect fuel normally include the motor not starting, running unevenly, decrease in power, wearing of the high-pressure pump, damaged or blocked injectors, and so on. These are several of the most frequently seen Diesel in Petrol warning signs, and should you recognise any of them then stop driving and have it removed right now.

Diesel in Petrol Questions

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.
