Petrol in a Diesel Volkswagen Vento? Start With the Tank
The size of the fuel tank is one of the earliest things worth knowing after you have put petrol in a diesel Volkswagen Vento, as the share of the fuel that's currently petrol depends on it. The tank and the engines are listed on this page for every Volkswagen Vento version that we hold data for.
The advice doesn't vary with the figure after it has occurred. Keep the engine off then phone Petrol in Diesel, after which we'll come and drain the car where it stands.
Each version in turn: Volkswagen Vento fuel tank capacity
On the Volkswagen Vento, the diesel tank takes 55 litres, and it is the same on every version we hold data for.
| Version | Fuel tank |
|---|---|
| Volkswagen Vento 1.9 D | 55 litres |
| Volkswagen Vento 1.9 SDI | 55 litres |
| Volkswagen Vento 1.9 TDI | 55 litres |
| Volkswagen Vento CL 1.9 TD | 55 litres |
| Volkswagen Vento TDI | 55 litres |
What a few litres means with wrong fuel in your Volkswagen Vento
The share of petrol rests on how full your tank was before you filled up. That is because wrong fuel in your Volkswagen Vento mixes with whatever diesel is still in there. When a couple of litres of unleaded go into a tank sitting close to empty, they make up a far bigger part of what the motor would take in. Added to an almost full tank of up to 55 litres, the same quantity is only a minor share of the whole.
Drivers often want to know how much petrol counts as too much. Running your engine is what moves the blend from your tank and through your pump and the injectors, and so the more useful point to know is whether it has run.
A drain is the right course whatever the share, and with a modest volume it is generally all your Vento needs.
Engines fitted to the diesel Vento
When you phone, it is useful to have read the badge beforehand, since the name of the version on it tells us which motor your Vento has.
Our data show TDI, SDI and TD badges on all diesel versions of the Vento.
More of them wear the TDI badge than any other one, though the Vento 1.9 SDI wears the SDI badge instead.
Every motor in our figures is 1.9 litres.
When you call, we can figure out which version it is between us, even if you are not certain of it yourself.
Tank size and AdBlue in a diesel Volkswagen Vento
Tank size plays out differently with AdBlue. AdBlue is mostly water and does not blend with diesel, and so with AdBlue in a diesel Volkswagen Vento, your diesel surrounding it does nothing to dilute it. As it sinks to the base of your tank, where the fuel pump draws from, even a small amount reaches your fuel line.
Nothing in AdBlue burns, and your pump gets no lubrication from it. When its water dries out, urea is left in the lines and the fuel filter as crystals, and the metal around it corrodes.
On certain diesel cars, AdBlue has a separate tank of its own, and its filler commonly sits alongside the diesel one under the same fuel flap. If your Vento has an AdBlue filler, the AdBlue filler cap is usually blue and takes a slimmer nozzle than diesel.
A fuel drain on your Volkswagen Vento, step by step
The whole tank is emptied in a fuel drain on your Volkswagen Vento, however large the tank is in your version, without the car moving from where it sits. Drawing out the tainted fuel comes first, followed by a rinse of your lines and the fuel filter. Then we top up with fresh diesel, prime the fuel system and fire up your engine.
Still on the station forecourt or sitting on your drive, your Vento can be emptied either way. When we finish this drain, your car is running on clean diesel and free to drive away.
What AdBlue removal from a diesel Volkswagen Vento takes
AdBlue gathers at the bottom of your tank instead of blending in, and so emptying it completely is the first step of AdBlue removal from a diesel Volkswagen Vento. If the engine has run, we flush the lines and the filter through as well and replace the fuel filter if it needs it.
AdBlue that has got into the diesel tank is the topic here. Disabling or removing the car's AdBlue system isn't part of that.
The price of a fuel drain on the Volkswagen Vento
The same model can make for very dissimilar jobs, which is why we do not list a fixed price. Whether the Vento has been run or driven changes it most. After that it rests on how much went in compared with your tank size, whether petrol or AdBlue went in, and the car's location.
Those details are what we need to explain what the work takes. Call with them ready.
Petrol in a diesel Volkswagen Vento: tank questions
Fuel tank capacity of the Volkswagen Vento: how much does it hold?
Every version we hold figures for shares one tank, and it takes 55 litres.
Is petrol less of an issue in a bigger tank?
Less of the whole is petrol when a couple of litres go into a larger tank, but it's still there, and running the engine still takes it to the pump. A drain removes all of it as long as your Vento is turned off.
Diesel versions of the Vento: how many do you list?
Our data cover 5 diesel versions of the Vento, all listed in the table above, so you can spot yours there by the name shown on its badge.
What counts as wrong fuel in my Volkswagen Vento?
Petrol qualifies whatever the grade, super unleaded too, and so does AdBlue that was meant for its own dedicated tank. Anything other than diesel in the diesel tank is wrong fuel.
Do you come to the Volkswagen Vento to drain it?
Yes, wherever it is. Parked at home or still at the pump, the vehicle remains where it is and is not started, as we travel to it.
