Audi Fuel Drain


Putting Petrol in a Diesel Audi is a usual mistake to make. And exactly what you should do about it will depend on various things. In case you would like to find out what you ought to do to sort it out then keep on reading.
Listed here are the most important factors to be aware of whenever deciding on whether or not to have a fuel drain:

  1. How much Petrol have you put in the Audi, taking into consideration that the fuel capacity of your Audi A1 TDI is probably about 45 litres?
    1. A modest amount of Petrol, as little as 2.25 litres of Petrol in a Diesel A1 TDI will generally not necessarily be a big problem. Experience has demonstrated to us that an amount under 2.25 litres (which is approximately 5% of the entire fuel tank capacity) is usually able to be adequately diluted through entirely topping the tank with Diesel.
      It is very unusual to encounter a car or truck having problems because of under 5% incorrect fuel contamination. Bear in mind that it is very unusual - not impossible to encounter. You can get certain motor vehicles that don't endure any degree of fuel contamination in the slightest.
    2. Between 2.25 and 4.5 litres of Petrol in the Audi (from 5 to 10%) is more of a 50/50 scenario. Our experience has revealed that as many people get away with it as those people who don't. Whenever you are deciding on whether or not to chance it and simply top it up recognise that it is very much like gambling all of it on black - you've got a 50/50 possibility of it being ok.
    3. Anything over 4.5 litres of Petrol in a Diesel A1 TDI ought to promptly be removed seeing as your likelihood of driving with that quantity of contamination is in all likelihood lower than one in fifty - genuinely long odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you spotted any performance issues after putting the incorrect fuel in the A1 TDI? If you have, have it removed irrespective of the volume of Petrol or even the contamination percentage. Continually driving an automobile that is now beginning to suffer from the effects of wrong fuel contamination will probably only end up in even more harm being caused to the fuel system parts.
  3. Would you like assurance?
    You should get it emptied. Regardless of the contamination ratio, there is always some extent of threat linked with driving a Diesel engine on fuel contaminated with Petrol. Likely final outcomes of driving a vehicle on the wrong fuel include the engine not starting, running unevenly, loss of power, degradation of the high-pressure pump, damaged or blocked injectors, etc. These are some of the most common Petrol in Diesel signs and symptoms, and if you recognise any of them then stop and have it removed right now.

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.
