Does the in tank fuel pump prime when the van unlocked or door opened? Should I be able to hear it?

A quick DIY way to test fuel lift pump's basic functionality. The test takes advantage of engine's fuel high pressure sensor (in fuel rail). Running the lift pump continuosly makes the pressure eventually "leak" through high pressure pump and can be detected by fuel pressure sensor. As a side...

Here’s an odd one folks. Four occasions now I have almost stopped and the engine cuts out (start stop), once prematurely, the rest as normal. On trying to restart, it just judders constantly. I’ve been in awkward positions when it happened and after a minute or so, switch it all off, then...

Hi do the fuel pumps prime when ignition turned on I’m sure when I got the van I could here it pumping when ignition was on but here nothing now when van first fires in the morning get a slight judder not every time if you give it a bit of gas it goes straight away ran it though vcds both pumps...

So, I’m just on my way back to the service centre to collect my van again! https://www.t6forum.com/threads/start-up-fault.33384/ After the centre replaced the crank sensor ( third visit, first visit fuel pressure sensor - second timing belt and tensioner ) the problem worsened dramatically...

Changing my cam belt following the forums instructions carefully as its the first one I've done. 2.0lt 150bhp. 2017 Have the timing covers removed and checking the setting pins (with the old belt still on) notice that the fuel pump is off what the vw service manual specified. Looking about a...

Have just re installed fuel tank after being off van for about 4 weeks (t6 150dsg) and flattened the battery trying to start it! Recharged the battery and after about 30 seconds cranking she fired up and seemed to run perfectly on the drive. Next day exactly the same, took about 30 seconds...

Have just taken delivery of my T32 Kombi LWB 199, which is generally great, however there is a hissing noise from the region of the fuel tank. It starts on starting the engine and is audible from inside, loudest around the bench seat. Stepping outside it is much louder and appears to be coming...

Hi all, I'm having some trouble with my underslung diesel heater installation on my T6 and any advice would be greatly appreciated. I've placed the diesel pick up line in the sender unit (not 100% sure where the "loose" end needed to go), I've attached an image looking from above. Van starts...

I have to drain all the fuel from an almost full tank. Anyone know where the relays are to power the pumps so I can disconnect the fuel line in the engine bay and get it to pump its own fuel out? Or, anyone know an easier way?

Hi I have just picked up my brand new T32 204ps 4motion and it has driven like a dream for 10 days the engine has been purring so beautifully quiet. I filled the tank up with fuel on the 10th day and drove off with a terrible hissing sound coming from the fuel pump just below the fuel caps and...

as above really, my t30 204 dsg panel van unnoticed this morning has a hissing noise at idle from underneath, almost sounds like gas is escaping from the exhaust. Anyone else got similar?
