Turbo boost sensor 03K 906 051

[JOHNST6]

Hi all can anyone tell me is this the turbo boost sensor 03K 906 051 location in t6 transporter 2019 4motion. And how best way to remove it will i need to remove the EGR pipe to get access ?

Looks like the MAP Sensor (Manifold Air Pressure) on the front of the Engine. Was looking at this a couple of days ago on mine, and what a pain it would be to get at. Front end would most likely need to go into the "Service Position" to create enough room to get at it.

If i remove the EGR pipe which is just above it in the picture i think its do able... is that pipe a simple take off and bolt back on when done ?. My second question is that sensor the Turbocharger Boost Sensor P023600

Not certain about the sensor ID, it will measure air pressure from the inlet into the charge cooler so possibly what you are looking for. The EGR Pipe does have gaskets which I believe are "crush" type, and probably need renewing. You should also confirm your Engine code and sensor location. Had a quick read of some info and it looks like there are possibly different locations for "G31 boost sensor"

Thanks for the reply i can see a sensor just below the pipe VIN: WV1ZZZ7HZKH081583
Car: Volkswagen Transporter
Year: 2019
Body type: VAN
Engine: CXHA

CXHA code matches up with the picture you showed originally, so yes, I would take that as the boost pressure sensor. Have you ruled out air leaks in the system as well? That could give false signals back to the ECU I would think. You have VIP membership and can access all the same info in the downloads. Best of luck, hope you get it sorted

Thanks for all info and help it's much appreciated

You're welcome, if you are able to post a VCDS scan, there are others on here that can interpret the detail far better than me. Let us know how it goes.

Hi just an update I changed the sensor yesterday I managed to do it without taking off the front end. All in all took me about 30 mins looks to of fixed the fault . It was totally blocked up i could of cleaned and put back but i just replaced it .. what would cause it to block up. I do a lot of short journeys would that be it ?

What’s the mileage on the van (engine)?
That’s a serious deposit of sludge, more that I would expect from the PCV and ‘normal’ turbocharger leakage.
Is your engine consuming oil?
The induction manifold must be heavily fouled as well.

Hi the van has 160km on it engine not consuming oil to that I can see.

Short and underloaded journeys are the death of all diesels. They regularly fail to get to proper operating temperatures and the regular stop/start just increases internal wear rates.
Good maintenance and regular service will help along with a good run every so often.

I hear you i give it a long run once or twice a week and got rid of the stop start again thanks for the support Rich
