2011 and my MAF sensor is not there, anywhere else it could be? There are no connectors to that intake in my engine bay.. 2011 Q5

[@TheBoss-co5tz]

Hello am looking for the intake air temperature sensor (iat) on the 2014 audi q5 . But the one you showing is mass flow sensor. Is there another one?

[@protipsplus]

See kzbin.info/www/bejne/pmmTmmppbtCLY7csi=4n-19FyoqYF-6cpJ. The description of the sensor does not include temperature. However, based on visual inspections of the intake, MAFS, and MAP sensor design (fence). The design is consistent with other combination MAP/Air sensors. Great question.

Hi @protipsplus, My son's 2010 A6 has a code of P0175 (Mass Air Flow Sensor) P0304, P0018 & P0011, which one of these should I concentrate on first? Should I get him a tune-up first before addressing the code(s). And my biggest question is, should I emphasize going to Audi dealer or will a reputable mechanic do just fine? Thank you in advance

[@protipsplus]

Need a little more information. Mileage, last spark plug/ coil change(P0304), P0018 indicates cam/crank shaft issues, P0011 indicates low oil. 1. Tips - if its been more than 7K, get an oil change and or top off oil. 2. if its been more than 12K, replace air filter. then 3. See. kzbin.info/www/bejne/sKendJKnqLpnbNEsi=kged0iwdPBUHqCDU. Let me know how it goes before heading in for a repair.

@protipplus I have 2011 Audi Q5 and when I drive it like 2 miles the ECP light comes on and it starts to idle rough or dies when I stop. Once you turn car off and turn back on the light is gone. It will idle all day and not throw the light but when I drive it does. Any ideas?

[@protipsplus]

If you know that the intake manifold and valves have been cleaned within the last ~30k, then I'd look towards timing related issues (Cam shaft adjuster Magnet, VVT solenoid, timming belt bridge).

The mass airflow sensor connector on Audi Q5 (R8) 2015 2L Petrol isn't on the big hose where it is on your car!! Coud the connector be somewhere else?

[@protipsplus]

On the 2015 the MAFS located along the air intake hose near the air filter housing. The MAP sensor is located along the air intake hose near the driver side headlight kzbin.info/www/bejne/pmmTmmppbtCLY7c

[@DarenMiller-qj7bu]

Is it possible to run a voltmeter across the terminals to test for correct resistance?

[@protipsplus]

Yes, this is possible, but you'll need to figure out how to maintain a somewhat constant air stream across the sensor and within a specific velocity range. Check this kzbin.info/www/bejne/n6rGaIt7rrCraNEsi=dBocnnbx5KNaRzdm

[@DarenMiller-qj7bu]

@@protipsplus very cool, thank you!

[@yemenreyes7905]

Can you make a video on how to replace the mass air conector

[@protipsplus]

I use the technique in the linked video to repair broken connectors. The other alternative would include the use of a pigtail but pigtails can make your repair look like a hack job so I don't recommend it. See. kzbin.info/www/bejne/sJ-zkKiQeMaeba8si=C4nMOS2c4kRIaeZ0

Hi, I’m currently looking for a mass air flow connector for my car the old one burnt and I am having trouble finding it. Can you please help?

[@protipsplus]

Send me the VIN number and I'll see what I can do. Thanks

[@aramb5482]

2018- models don’t look like that. Hmm I wonder if my 2019 has one I can access

[@protipsplus]

Can you provide a few details about the symptoms you are experiencing?

[@zagrosw2w]

Mine is 2015 model, and the sensor connector isn't where it is on the AUDI in this video!!! I just can't locate it!

[@shottaspot4147]

2011 I got oil inside

[@protipsplus]

That's not common. Let me know how it turns out.

[@rontv2244]

I must say these cars are not reliable. These kind of cars meed a tool box included because your in for an education as a mechanic with the things you will discover about the issues on this vehicle

[@protipsplus]

I'd say that it is a vehicle that requires higher maintenance. 😉 Great comment.
