I've just taken mine into VW dealer for same issues. They suggested the last dealer used wrong engine oil and charged me for an oil service plus diagnosis.
After collecting it and driving it home, the coil light came back on. So i've had it recovered yesterday and not heard anything yet.
I'll keep you informed as to what they say.

[evans1089]

That’s what I thought. So they’ve had it back

Any update @evans1089? Had a similar coil flash today that cleared after ignition off and on.

I never actually got an explanation or a report. It was dropped off to my house from VW and the driver didn’t have a clue. But it’a been great since. I’ll try find out next time i ring up!

Hi.. did you ever find out??
I have the same problem

I have the same problem, oil pressure sensors replaced and the warning light shows a lot more often now, goes back into a VW T6 experts in north Leeds this week. Starting to frustate now tbh!!

 

[Devonjames43]

Be nice to know what they say??

Van returned, garage has tested front and rear oil pressure sensors and both are deemed to be working correctly. Wiring has been replaced just in case on both sensors I'm informed but the problem persists. Two garages now have attempted to fix this and have had not joy. A detailed diagnostic report is being sent to VW to determine if there is a newly identified software issue on the ECU but I'm not holding out much hope regarding this this. Frustrated!!

Still no fix from T6 experts in north Leeds near the airport. I’m starting to wonder though if they have given up on this and the “sending diagnostic report to VW” is all smoke and mirrors?

 

[rover220]

mine turned out to be chaffed wiring. vw replaced many parts and it was back and forward until it was sorted.

Thanks, the mechanic at the garage said he looked into this, I'm having my doubts though.

I’m booked in now at York VW Van centre to investigate. Any info in which wire / wiring loom was chaffed so I can request they look at this first? My van is becoming a money pit!!

Mine was fixed by VW in the end. Oil pressure Relief Valve

Be interested to know what VW come back with regarding this. I’m now at my third independsnt VW garage and they don’t know the fix

 

[HamishT6.1]

Update for you all,

Got van booked in to VW Ballieston and they came back to me saying the wires for exhaust sensor and Knock sensor had been chewed through to the wires and that's what's been causing lights to come on on the dash,

All in,£900 to fix....

I asked them why there isn't an under tray fitted and was told new transporters don't come with them, you have make one yourself.

I have asked for the sensor's back and I'll repair the wires and keep for spares

I've been quoted roughly the same at an Independent dealer in Leeds, but with no guarantee of fixing the issue. Seriously frustrated with this!

I've got this same error at moment, only happens when you accelerate hard. Need to see if the garage can sort it or i do it myself.
