Question about 2002 Audi A4

1 Answer

00 Audi A4 stalls

Just had mass airflow sensor replaced but car still stalls during take-off 1st thru 2nd gear. Seems to be more prominant when going up an incline or hill. Maybe not getting enough fuel from bad fuel pump? Any idea???

Check all air intake pipes, for vacuum leaks, even the small ones and the hidden ones. try spraying brake cleaner spray around the engine when its running. if the revs pick up you have found your leak. also check the throttle body butterfly. clean it !!! after that coolant temp sensor.....

Try unplugging the Mass Airflow sensor and see if the car runs better, if it does replace the MAF sensor. It is located in the air intake hose to the engine.

I own a 2003 Nissan Altima SE 3.5L. Recently, my car sounds like it is stuck in 2nd gear. The RPM's do not run high but the car sounds like it is racing in second gear. This is an automatic. Help?!


If your service engine soon light is on, go to autozone and have the code pulled up. Sounds like you are in limp mode (safe mode). I suspect it is your mass airflow sensor. Its easy to replace but expensive. I recommend getting one from a junk yard and installing it yourself. if you dont have any mechanical experience dont worry. As soon as you see one it will be obvious you dont need experience. It is in the middle of the big tube that connects your air filter to the throttle body. All you need is a screw driver and disconnect one electrical connector. Again, not worth buying new...they cost over $350 new but only $60 at junk yard.

If you want a quicker way to check, dissconnect the big tube from the intake manifold, in essance letting air run directly to the throttle body without going thru the air filter or mass airflow sensor. If the car runs fine with it dissconnected, its the mass airflow sensor. Buy some mass airflow sensor cleaner at an auto store (its specifically made and named mass airflow sensor cleaner). Try to clean it first...Dont touch anything inside with your finger tho.

Sorry if Im sounding like a school teacher but Im not sure of your mechanical knowledge or ability.

If not none of this works , you will have to pull up the code.

Change the transmission fluid ant if that doesn't work then the transmission needs rebuilt or replaced. If you get on craigslist someone might be selling a transmission for cheap or check the salvage yards.

I have a 1999 Audi A4 2.8L - Last month it was stalling at low RPM after initial start idle kicked down. I put in fuel injector cleaner and it fixed the problem. Yesterday it returned and is shaking before...


Crank shaft sensor or air mass meter, is this a v6? I had the 2,6 a4 same fault same miles funny enough. changed the air mass meter is was ok after that. thing is they have so many sensors, you need to get it on a diagnostic machine to be sure.

Audi A4 Auto, Gear changing trouble


Did you change the transmission filter? Sounds like no Front pump pressure. dirty filter will cause cavitation of the pump and damage to pump. Damage to cutch packs will occur too. Do not run until investigating filter, make sure o ring or grommet in valve body is present for filter

1998 audi a4 quatro - where is the coolant part in


CTS is at the back of the engine, behind and below the passenger side cylinder head, beneath the intake pipe going from the mass airflow sensor to the throttle body. It's either black or blue in your car, has four wires coming off the connector plugged into the top of it, and has a retaining clip that holds it as well. Get a new clip when you buy the sensor - they're plastic and break easily.

Mass airflow meter


Hi

It is fitted to the air filter outlet hose (the one which goes from the air filter to the turbo) and it is quite literally right next to the air filter. It has a wiring plug to it.
