Yes, it is true. At least on most relatively modern European vehicles.

 

Thanks

 

Who Dafuq (@Tampa Tramp, @Sceep ) and why would anyone go inside the vehicle for something (in the middle of a fuel filter change) when you're all dirty and your hands are covered in diesel? Had to be some butcher working on someone else's vehicle!

 

some of us can actually do a fuel filter change without making a mess

 

A bit off topic but back in Europe mk2 golf Tdis had a function that when you opened the drivers door the glow plug circuit would activate so by the time you went to start the car they would be up to temp.
Thank goodness we have quick heating plugs now

 

Probably would be a good idea to remove fuses/relays associated with fuel pump when doing the job to avoid an accidental activation.

 

Not 100% sure on a Treg but when the missus accidentally filled her Tiguan with petrol/gasoline. She called me and I told her not to start it & have it towed direct to the stealer. The stealer told us that fuel pump is activated by the drivers door so the petrol/gasoline has already been pumped through the system. They drained and got it going fairly cheaply and about 2 months later the low pressure fuel pump died, most likely from having petrol/gasoline go through it. Be surprised if the Treg doesn't have the same system, but happy to be corrected.

 

My Golf GTD did - can confirm I've done the same. Haha

 

Nothing like this or turning on the ignition activates the pump in ours (vehicle in sig).
I had a piece of plastic hose on the output tube of canster, hoping it would fill it -
didn't, so just filled it through the input tube with another short hose and small funnel.
No touble starting it or any hesitation after starting.
I believe you would have to communicate with car to activate the pump with out engine running.
