What the Tank Holds: Petrol in a Diesel Alfa Romeo 147
Someone who has got petrol in a diesel Alfa Romeo 147 wants to find out the capacity of its fuel tank early on, since that decides how much of the fuel in there is currently petrol. Every version of the Alfa Romeo 147 we have data for is on this page with its tank size, and the same goes for the engines it came with.
After it has happened, the same advice applies whatever the number is. Call Petrol in Diesel with your engine kept off. We will come out to you and drain it right where it sits.

On the Alfa Romeo 147, the fuel tank holds 60 litres, and it's the same on every version we have figures for.

Wrong fuel in your Alfa Romeo 147: what a few litres amounts to
How full the tank was when you filled up decides the share of petrol, as wrong fuel in your Alfa Romeo 147 blends with whatever diesel was still in it. Up to 60 litres go in the tank. Filling an almost full one with a couple of litres of petrol leaves only a small share of petrol in the total, while the same quantity in an almost empty tank makes up far more of what the engine would take in.
Drivers commonly want to know how much petrol counts as too much. Starting your engine is what takes the blend out of your tank and through your pump and the fuel injectors, so the more helpful thing to find out is if it has run.
A drain is the right option no matter what the proportion, and with a modest volume it is generally all your 147 needs.

When there's AdBlue in a diesel Alfa Romeo 147
With AdBlue, fuel tank size works differently. With AdBlue in a diesel Alfa Romeo 147, your diesel sitting in your tank doesn't weaken it. Being mainly water, AdBlue stays separate from your diesel and sinks to the base, which is where the pump pulls from. Even a tiny quantity gets into your fuel lines.
As the water in AdBlue evaporates, the urea left over forms crystals in the fuel lines and your filter and eats into the metal next to it, and AdBlue does not combust or give your pump any protection either.
The filler for AdBlue, on diesel cars that have it, often shares a fuel flap with the diesel one and leads to a separate tank. Where your 147 has an AdBlue filler, its cap is normally blue and accepts a smaller nozzle than the diesel filler.
A fuel drain on your Alfa Romeo 147, step by step
The whole tank is cleared in a fuel drain on your Alfa Romeo 147, however big it is in your version, without the car moving from where it stands. Clean diesel is put in once the tainted fuel is pumped out and the lines and your filter are purged, and then the system is primed and your engine fired up.
Whether your 147 is still at the forecourt or left on your driveway doesn't change anything. When we finish this drain, the car is running on clean diesel and free to drive away.
What AdBlue removal from a diesel Alfa Romeo 147 takes
Clearing your tank completely is how AdBlue removal from a diesel Alfa Romeo 147 starts, since AdBlue does not mix in and settles at the bottom instead. A motor that has been started means cleaning the fuel filter and lines through as well, plus changing your fuel filter if needed.
AdBlue that has gone into your diesel tank is the topic here. Disabling or removing the car's AdBlue system isn't part of it.
The cost of a fuel drain on the Alfa Romeo 147
The same model can mean very different call-outs, which is why we do not publish a fixed price. The biggest factor is whether anyone has started or driven the 147. Then comes the amount that got in compared with how big your tank is, which liquid it was, and where your car is now.
Those facts are what we need to explain what the work takes. Phone with them to hand.
