I am new to the Audi world. I have a 97 A6Q with 216K miles for my 16 year old. Being the great dad I am I was showing my daughter some basic mx around the engine and broke the nipple off the Boost sensor trying to change the air filter. What is a boost sensor and where can i find one? I searched 1000 different websites and none have a boost sensor listed. Is there a different name for this part? What does the Boost Sensor do?

 

give me the part no from the sensor, and i give u more info that will help

 

Looks like a MAP (Manifold Absolute Pressure) sensor. It is only a "boost" sensor when you have a turbo (or two...) and you are under boost. Otherwise, it is a vacuum sensor. It tells the ECU what the engine is trying to do and the engine sends the correct amount of fuel to the engine. You can epoxy the nipple back on to get you by until you get a new one.

Thanks. I found a few MAP sensors on line, but they didn't match, so I didn't think that was it. I will epoxy it until I find a replacement. NAPA was the only place locally (other than the dealer - $570) that had it for $380!! I knew it had something to do with the fuel mixture because the mpg dropped significantly. I don't have a turbo though???

 

send me your email in private message , and vin no , and what view and part no u need. i got something ready to send but more details u gave me , more details i may found.
