mas air flow sensor cleaner.
mas air flow sensor cleaner.
hello everyone,it is your favorite member here checking with you if you have ever try to use product by c r c mas air flow semsor cleaner.would you recommed this? esspecially if people use k&n filter.it says to use every 10 to 15k miles.i used it no probles so far.thanks,caug
Re: mas air flow sensor cleaner. (caug1)
I have only experience with the factory air filter,which has required zero MAF cleanings in the 188,000 miles I have on my Q
Re: mas air flow sensor cleaner. (caug1)
I also used the MAF cleaner and it seemed to get better gas mileage for a little while but now it seems like I never used it. I haven't had any problems with it though so I can't complain. Maybe I should use it more often.

i think it works. my gas mileage went up too. i also stop using cruise control or use it less, at lease still 19 mpg.lpae9132 wrote:I also used the MAF cleaner and it seemed to get better gas mileage for a little while but now it seems like I never used it.

How would you know if your MAF was dirty [inaccurate] or NOT.
A warm idle in park ~~ 1.120 volts at 1000' MFSL and 70F at 750 rpm
A very dirty MAF might read as low as 1.110
Same situation at cruise only a few hundredths difference good to bad under exact same atmospheric conditions.
Without a Consult looking at the block learn [adaptive learn] percent...you cannot begin to guess whether it is a dirty MAF, Dirty Injectors, or sluggish O2 sensors.
A dirty MAF usually makes the cruise lean or acceleration lean which gets corrected by the O2, if O2 are newish and spot on. CO and Nox emission go up as does combustion temperature = more spark knock.
A clean oem air filter, a PROPERLY AND CAREFULLY sprayed clean MAF, clean injectors [following BG44k and rail flush]...........then you can assume they are not the problem...........pointing to O2 sensors.
Without OBD2 the technican must be smarter, more experienced, and conduct more complicated expensive time consumming tests.
OBD2 is still a ROUGH TEST as things can be out of whack by 20% and still not throw a code. and you can have multiple 15% error that won't throw codes.
The tighter they zeroin the software the more critical maintenance gets!

I couldn't tell if my MAF was dirty but I used the stuff anyways just to make sure. It's not like it's expensive at all so why not use it.
