Air Mass Sensor: Buy Online & Save!

Hello, I have a problem. I was at a friend's place, and he said that my Passat doesn't have enough power for a 1.9 TDI with 115 horsepower.
We then replaced the mass airflow sensor with a new one, and lo and behold, the car runs great. javascript:emoticon('')
Very Happy: After starting it twice, I had the usual performance again.
We then swapped two more parts, and they are both located on the rear side of the engine.
Everything without success. javascript:emoticon('')
Crying or very sad.
He now wants to replace the part connected to the mass airflow sensor and the part located behind the radiator. What else can be done?

I don't think anyone can really help you with that description.

Hi,

It's not going to work like this.
1. Read the error memory to check if the emergency program was activated.
2. Compare the actual and target values for LMM; the actual value must always be higher than the target value.

Best regards, Rainer.

Have you tried using the search function yet?

Even if you only enter '17964', you will be overwhelmed with results.

I am a nice guy, you know .

Error code: 17964.
Boost pressure regulation: Limit exceeded.

Possible causes:
Faulty turbocharger wastegate control valve (N75), leaky hose connections.
Turbocharger failure.
Air leak between the turbocharger and the engine (charge air path).

Possible impacts:
reduced performance.
Low boost pressure.

A boost pressure gauge can be incredibly helpful in this situation. Otherwise, first check the entire charge air system for leaks, and then continue troubleshooting.

Okay, thank you.

and the search function is absolutely great in this forum -> it's really worth using .
