Petrol in a Diesel Volkswagen CC: What the Tank Holds
The size of the fuel tank is among the earliest things to know after you have got petrol in a diesel Volkswagen CC, because the share of what is in there that's now petrol rests on it. The tank size and the engines are listed on this page for every Volkswagen CC version which we hold figures for.
After it has occurred, the same guidance applies whatever the number happens to be. Call Petrol in Diesel with your engine kept off. We'll come out to you to drain it just where it stands.
The Volkswagen CC fuel tank capacity on every version
Every version of the Volkswagen CC within our figures shares the same diesel tank, which takes 70 litres.
| Version | Fuel tank |
|---|---|
| Volkswagen CC 2.0 TDI | 70 litres |
| Volkswagen CC 2.0 TDI 4motion | 70 litres |
Wrong fuel in your Volkswagen CC: what a few litres amounts to
Wrong fuel in your Volkswagen CC blends with whatever diesel is already in the tank, and so the share of it that's petrol hinges on how full the tank was when you refuelled. How much petrol gets to the motor depends a lot on the level in your tank. The tank takes up to 70 litres, and on a nearly full one a couple of litres stay a small part of the whole, but in a tank sitting close to empty the same few litres make up a much greater share.
Frequently, drivers want to know at what point that petrol becomes too much. The more helpful point to check is whether your engine has been run, because starting it is what moves the blend out of the tank and through your pump and your injectors.
A fuel drain is the safe course no matter what the proportion, and with a small quantity it is normally all your CC needs.
Diesel CC engines and the badges
The version name on the badge tells us which motor your CC has, so it is worth checking before you call.
Diesel versions of the CC in our data wear TDI badges.
All of them use the same engine size, 2.0 litres.
Within the CC versions we have figures for are 4MOTION ones.
Once you ring, we can work out which version it is between us, even when you are not sure of it yourself.
What goes on with AdBlue in a diesel Volkswagen CC
AdBlue alters what the size of the tank means. With AdBlue in a diesel Volkswagen CC, the diesel sitting in the tank doesn't thin it. Being largely water, AdBlue keeps separate from your diesel and sinks to the base, which is where the pump pulls from. Even a small volume gets into the fuel lines.
AdBlue doesn't burn and gives the pump no protection, and as its water dries out, the urea left over crystallises in the fuel lines and the fuel filter and eats into the metal next to it.
On certain diesel vehicles, AdBlue has a separate tank of its own, and its filler frequently sits alongside the diesel one under the same flap. Where your CC has an AdBlue filler, its cap is generally blue and fits a smaller pump nozzle than the diesel one.
How a fuel drain on your Volkswagen CC works
A fuel drain on your Volkswagen CC empties the whole tank, whatever its size on your version, and it is carried out where your car is standing. First the contaminated fuel is pumped out, then your filter and fuel lines are cleaned. After filling up with clean diesel, we re-prime your system and fire up the engine.
Still at the forecourt or sitting on your drive, your CC can be drained just the same. Fresh diesel is what it runs on when this drain is finished, and so you can take it away.
How AdBlue removal from a diesel Volkswagen CC works
AdBlue removal from a diesel Volkswagen CC starts with emptying the tank fully, as AdBlue gathers at the bottom instead of mixing in. An engine that has been run means flushing the filter and lines through as well, and replacing the filter if it needs it.
AdBlue that has gone into the diesel tank is the topic here. Disabling or removing the car's AdBlue system isn't part of it.
What a fuel drain on the Volkswagen CC costs
Two jobs on the same model can be quite different, so we don't publish a fixed price. The biggest factor is whether anybody has run or driven the CC. Then comes the quantity that went in compared with how large your tank is, which fuel it was, and where your car is now.
With those facts, we can let you know what this job will need when you call.
Your tank queries on petrol in a diesel Volkswagen CC
What does the Volkswagen CC fuel tank capacity amount to?
It holds 70 litres, and every version we have figures for shares that tank.
Is petrol less of an issue in a larger tank?
In a larger tank, petrol is a smaller part of the total, yet it has not gone anywhere, and it reaches the pump as soon as your engine runs. All of it is cleared with a drain, as long as your CC is turned off.
Do you list more than one diesel CC?
Our data cover 2 diesel versions of the CC, all listed in the table above, and so you can find yours there using the name shown on its badge.
Which fuels, other than diesel, would be wrong fuel in my Volkswagen CC?
Petrol counts whatever the grade, super unleaded included, and so does AdBlue that was intended for its own separate tank. Everything other than diesel in the diesel tank is wrong fuel.
Wherever the Volkswagen CC is, can you drain it?
There's no reason to shift or start the vehicle. Whether it's parked on your drive or still on the forecourt, we come to it.
