125kw TDI Golf MkV BMN - Engine Speed Sensor (G28) and P3138 Intake Manifold Dev Errs

[Transporter]

SO I just got this error again after having the sensor replaced 6 months ago, and I think you are right. Cranking issues throwing a g28 error don't necessarily mean its a G28 sensor error...

I am cranking on cold and hot starts, maybe 3 to 4 3 second attempts before firing. Some longer.

Been though a few diagnostic videos, fuel pump, filter, VVT (not sure I have this though) - not sure what to do yet.

Maybe it’s a time for new battery.

Look at the starter motor , then battery
