Audi Fuel Drain


Filling up with Petrol in a Diesel Audi is a fairly typical mistake to make. And its remedy hinges on an assortment of factors. In the event that you want to know what you need to do to sort it out then keep reading.
Listed below are the most important variables to take into consideration whenever deciding whether to have a fuel drain:

  1. Exactly how much Petrol did you put into the Audi, taking into account that the fuel capacity of your Audi Allroad Quattro TDI is probably roughly 70 litres?
    1. A tiny quantity of Petrol, as little as 3.5 litres of Petrol in a Diesel Allroad Quattro TDI will in most situations not really be a major problem. Experience has proven to us that anything under 3.5 litres (roughly 5% of the fuel tank capacity) is usually capable of being sufficiently diluted by completely filling up the remainder of the tank with Diesel.
      It is relatively unusual to come across a motor vehicle suffering from difficulties due to under 5% wrong fuel contamination. Bear in mind that it is infrequent - in no way impossible to find. There are actually some automobiles that don't endure any amount of contamination in the slightest.
    2. Anywhere between 3.5 and 7 litres of Petrol in the Audi (5 to 10%) is really a 50/50 situation. Our expertise has proven that as many motorists get away with this as all those who don't. Whenever you are deciding whether or not to risk it and just simply top it up remember that it is exactly like betting your car on black - you've got a 50/50 chance of it working out.
    3. Anything over 7 litres of Petrol in your Diesel Allroad Quattro TDI should immediately be removed seeing that your probability of getting away with this amount of contamination is certainly lower than one in fifty - seriously long odds.
  2. Put some Petrol in a Diesel Audi and drove it: Have you spotted any kind of performance concerns after putting the wrong fuel in your Allroad Quattro TDI? If that's the case, have it removed irrespective of the amount of Petrol or the contamination ratio. Proceeding to run running an automobile that is currently beginning to suffer the consequences of fuel contamination will probably definitely result in even more damage affecting the fuel system.
  3. Do you want security?
    Simply get it emptied. Regardless of contamination ratio, there is inevitably some amount of threat connected to running a Diesel engine on fuel contaminated with Petrol. Possible results of driving on the wrong fuel normally include the engine refusing to start, running lumpy, losing power, wearing of the high-pressure pump, worn or blocked injectors, and the like. These are a few of the most typical Petrol in Diesel signs and symptoms, and should you notice any of them stop driving and get it removed immediately.

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.
