Car Forum / Volkswagen / Water Cooled Volkswagen Cars / April 2007Location of MAF
Hi, Can anyone be kind enough to point out where the MAF might be on a vw 1.6 16v golf its a 2001 model. The cars been using quite a bit of petrol and someone suggested its the MAF, not sure what that is or what is does ? But suggested disconecting it and watching the MPG and if it improves buy a new one for £70. Appreciate any info on this, quite interested in what a MAF is and what it does and what disconnecting it does in relation to getting better petrol usage and if it does the engine any harm ?

With it disconnected the car will throw an error, and probably perform badly, but will run. It may or may not trip the warning light- I don't know with a petrol. > Mass Air Flow sensor.

There will probably still be a warning light on the dash. >> Mass Air Flow sensor. Usually in the trunking from the air cleaner.

With the maf disconnected, the ecu will use 'default' parameters to control fuelling (as it gets no signal from the maf). If the car runs exactly the same as it did with the maf connected, the maf is probably ok. If it runs better when disconnected, the maf is most likely goosed. Only true way is to hook the car upto vag-com and log on the results of the maf. Only a petrol car, the maf readings should peak at around 80% of the cars bhp.....i.e., on a 105bhp 1.6, the peak air flow should be around 84. > Only true way is to hook the car upto vag-com and log on the results of the maf. Is right IME. Unplugging as a quick test is OK but not 100%. |
