Default Boost Pressure Sensor Location

Does anyone have a diagram that can indicate where the boost pressure sensor is on the 2006 Jetta TDI engine?

If needed, I can post a picture.

I found this link. Not sure if it is the same for the 2006 Jetta, but will check it out and see if it works.

Isn't it down the bottom of the boost pipe that goes from the intercooler to the inlet manifold? If not they're usually on that pipe somewhere on most tdi's.

It's on the intercooler outlet, behind the radiator. It will be near the right headlight.

Yep, right up top.

Wow, that will be totally easy to replace. VW dealership wanted over $300 to replace it.

In case anyone wonders what the symptoms are, when accelerating, the vehicle would feel like it was losing power. Could be the limbo thing, but it quickly goes away once you start accelerating. I will try cleaning it first then order a replacement.

Thanks

So what makes you think it is the boost sensor?

Default Well.... That is what the dealers mechanic said it was

So, hopefully that is the issue.

That is why I am going to pull it and check to see if it is dirty. New Mexico is pretty dusty this time of year.

Do you have any experience with this sensor and what a dirt/failure might act like?

Is there a way to test the boost pressure sensor?

LOL... OK, so we really have no idea what is wrong then.

What are the symtoms of the engine's operation? Are there any DTCs stored?

My mechanic said there were no codes. He said to take it to the dealer. Dealer did the diagnostics (hopefully ) on it and said it was the Boost Pressure Sensor. If it still doesn't work, I will have my mechanic take another shot at it.

OK, please stop right now. You are getting ready to take a shot gun approach to something, and you still have not answered a simple question: what symptom does your car have right now? All we know so far is the typical he-said/she-said nonsense. We can help you, you just have to help us help you.

If you go back to my post at 1:48PM I said:

In case anyone wonders what the symptoms are:, when accelerating, the vehicle would feel like it was losing power. Could be the limbo thing, but it quickly goes away once you start accelerating. I will try cleaning it first then order a replacement.
--------------

Additional information: The symptom lasts for just a few seconds and then it is fine. It occurs within the first few minutes or driving. Low power (seems bogged down) then the issue clears and drives with full power. My mechanic buddy says the turbo surges. To me it feels more like it bogs down.

You can test everything relevant with VCDS using run-up tests and basic settings mode. You should also test the vane actuator with a vacuum pump while visually watching it as well as having a helper watch VCDS for the reported position.

The MAP sender is solid state and is not affected by dirt, oil, etc. The only thing that can go wrong with it is if the transducer itself goes bad due to a defect.
