Volkswagen Fuel Drain


Filling up with Petrol in a Diesel Volkswagen is a usual error. And its solution depends upon several things. In the event that you want to know what you have to do to sort it out then keep on reading.
These are the key variables to be aware of when deciding whether to have your car drained:

  1. How much Petrol did you put in to the Volkswagen, taking into consideration that the fuel capacity of your Volkswagen Passat TDI is in most cases about 70 litres?
    1. A modest amount of Petrol, something like 3.5 litres of Petrol in a Diesel Passat TDI will in most cases not be a huge problem. Experience has demonstrated to us that quantities less than 3.5 litres (which is 5% of the whole fuel tank volume) is generally capable of being adequately diluted by means of wholly filling the remainder of the tank with the appropriate fuel.
      It's extremely rare to come across an automobile experiencing difficulties with below 5% wrong fuel contamination. Remember that it is unusual - in no way impossible to find. You will discover some automobiles that don't stand any level of contamination at all.
    2. Anywhere between 3.5 and 7 litres of Petrol in the Volkswagen (from 5 to 10%) is more of a 50/50 condition. Our expertise has demonstrated that as many motorists get away with this as those who don't. When you are trying to decide whether or not to risk it and basically fill it up consider that it is very much like gambling everything on black - you have got a 50/50 chance of it working.
    3. Anything more than 7 litres of Petrol in a Diesel Passat TDI must straight away be drained since your probability of succeeding with that level of contamination is more than likely lower than one in 50 - truly big odds.
  2. Put some Petrol in a Diesel Volkswagen and drove it: Have you noted any kind of performance troubles after putting the wrong fuel in the Passat TDI? If so, have it removed no matter the quantity of Petrol or even the contamination percentage. Proceeding to run driving a vehicle that is now starting to suffer from the effect of wrong fuel contamination will probably likely bring about more and more harm affecting your fuel system parts.
  3. Do you need assurance?
    Then simply just get it emptied. Whatever the contamination percentage, there is inevitably some amount of threat linked with running a Diesel engine on fuel contaminated with Petrol. Likely outcomes of driving a car on the incorrect fuel normally include the engine not starting, running lumpy, lack of power, wearing of the high-pressure pump, worn out or clogged injectors, and so forth. These are several of the most frequently seen Petrol in Diesel warning signs, and should you observe any of them cease driving and get it drained immediately.

Petrol in Diesel Questions

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.
