Audi Fuel Drain


Filling Petrol in a Diesel Audi is a fairly typical error. And exactly what you need to do about it will depend on various things. Assuming you want to know what you ought to do to sort it out then read on.
Right here are the most important factors to be aware of whenever deciding on whether or not to get a fuel drain:

  1. How much Petrol did you put in the Audi, bearing in mind that the fuel capacity of your Audi A6 TDI Quattro is usually roughly 80 litres?
    1. A small quantity of Petrol, as little as 4 litres of Petrol in a Diesel A6 TDI Quattro will in most cases not necessarily be a significant problem. Experience has taught us that quantities under 4 litres (which is about 5% of the total fuel tank capacity) is quite often able to be adequately diluted by means of entirely topping up the tank with Diesel.
      It's relatively uncommon to come across a car or truck having issues due to lower than 5% incorrect fuel contamination. Keep in mind that it is very unusual - definitely not impossible to find. You will discover a number of automobiles that won't endure any amount of contamination at all.
    2. Between 4 and 8 litres of Petrol in the Audi (5 to 10%) is really a 50/50 situation. Our practical experience has demonstrated that as many drivers get away with it as those people who break down. Whenever you are trying to decide whether to chance it and just simply fill it up remember that it is the same as gambling all of it on black - you will have a 50/50 possibility of it working out.
    3. Anything over 8 litres of Petrol in a Diesel A6 TDI Quattro really should immediately be removed as your probability of driving with this quantity of contamination is probably below one in 50 - seriously huge odds.
  2. Put Petrol in a Diesel Audi and drove it: Have you seen any kind of performance problems since putting the wrong fuel in the A6 TDI Quattro? If you have, have it removed no matter the volume of Petrol or even the contamination ratio. Continually running a car that is currently starting to suffer from the effects of fuel contamination will probably typically lead to more and more harm affecting your fuel system.
  3. Would you like assurance?
    Then simply just get it removed. No matter the contamination ratio, there is invariably some extent of threat resulting from running a Diesel vehicle on fuel contaminated with Petrol. Possible implications of driving on the incorrect fuel normally include the engine refusing to start, running unevenly, decrease in power, degradation of the high-pressure pump, worn or clogged injectors, etc. These are several of the most typical Petrol in Diesel symptoms, and should you recognise any of them then cease driving and have it removed 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?


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.
