ENGINE LIGHT ERROR

[ERCINOU]

Hi to everybody, i have a vw T6.1 2019 2L 102 HP, 145000 km.
The engine error light turned ON for two days than OFF. A few days later it is ON again.
I connected the diagnostic DELPHI and i have the message " LOW PRESSURE CYLINDER 3".
The engine works very fine, any start perfect and nothing wrong appears : exaust pipe smoke, temperature, mecanic noise or so.
Comsumption is still perfect, 6,8 L/100 Km.
I don't know if is a problem that th engine goes over 2500 RPM very rarely due to my way of driving.
I am wondering about the engine itself or the "pressure sensor" if there is one and how the mesure is made to display the mistake.
Thanks for read me.
Regards. Aurelio.

There is a cylinder pressure sensor built in to glow plug no.3 - this is likely to do with that sensor.

Ideally, more info / description on the fault code is required to investigate further. I.e wiring / or the actual glow plug.

Hi to all and thank you very much for info, this helped me to find the issue. In fact, the glow plug 3 is dead.
Kind regards.
