Don't start your vehicle to avoid damage to your engine, even if you have wrong fuelled your vehicle with a little bit of fuel. Push your car in neutral to a safe place and call GMM1.

If you have wrong fuelled your vehicle and then drove it, this can cause serious damage to your engine. It is of utmost importance to fuel drain the wrong fuel as soon you can so that the risk to your engine is minimised.

The more the contaminated fuel that goes into the system, the more expensive it will be to repair your car. It doesn't matter if you put diesel in a petrol engine or vice versa, you still need to call reliable roadside emergency fuel assistance.

Please contact your insurer for confirmation if they cover your insurance costs. However, the better thing to do is to cover the costs yourself to avoid an increase in your insurance premiums.

If you misfuelled your vehicle at a service station, then it is unlikely any damage has occurred as long as the ignition isn't started. GMM1 can drain and flush the system to get you on your way again.
