Audi Fuel Drain

ABOUT

Filling up with Petrol in a Diesel Audi is a usual problem. And its remedy hinges on an assortment of things. Assuming you want to find out what it is best to do to sort it out then stay with me.
These are the key variables to take into account whenever figuring out whether to have a fuel drain:

  1. What level of Petrol have you put in the Audi, bearing in mind that the fuel tank capacity of your Audi A5 TDI is normally around 65 litres?
    1. A modest quantity of Petrol, something like 3.25 litres of Petrol in a Diesel A5 TDI will more often than not not be a significant problem. Experience has proven to us that anything less than 3.25 litres (which is almost 5% of the overall fuel tank) is quite often capable of being completely diluted through wholly topping up the rest of the tank with Diesel.
      It's extremely rare to come across a car going through difficulties due to lower than 5% wrong fuel contamination. Keep in mind it is rare - not impossible to encounter. There are actually a number of motor vehicles that don't endure any amount of fuel contamination whatsoever.
    2. In between 3.25 and 6.5 litres of Petrol in the Audi (from 5 to 10%) is really a 50/50 situation. Our working experience has shown that as many people get away with it as all those who break down. Any time you are deciding whether or not to chance it and just fill it up remember that it is just like wagering all of it on black - you will have a 50/50 chance of it being ok.
    3. Anything above 6.5 litres of Petrol in a Diesel A5 TDI really should as soon as possible be drained out because your likelihood of succeeding with this amount of contamination is very likely lower than one in 50 - truly big odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you noticed any performance issues since putting the bad fuel in the A5 TDI? If so, have it emptied no matter the volume of Petrol or even the contamination percentage. Still driving a vehicle that is already starting to suffer the effects of wrong fuel contamination will definitely end up in increasing amounts of harm affecting your fuel system parts.
  3. Are you interested in assurance?
    Then get it emptied. No matter the contamination percentage, there is always some extent of danger associated with driving a Diesel motor on Diesel contaminated with the wrong fuel. Possible final outcomes of driving a car on the incorrect fuel can include the engine refusing to start, running unevenly, lack of power, wearing of the high-pressure pump, worn out or clogged injectors, etc. These are several of the most frequently seen Petrol in Diesel signs and symptoms, and if you recognise any of them then stop and get it drained asap.

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?

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