so pulling a po172 code i had just cleaned the air filter and my friend bumped the pipe that runs the coolant back. why they put this on the air box i have no clue didnt look like any got on it but seems a lil residue maybe in there as it pops on about 50 miles i cleared and it came back only code that is. Anyone done this i know they sell MAF cleaner just wondering whats best for an Audi

microfiber cloth should pull off all the real problems, won't get it looking like an out of the box part but it will get it back to working condition. Worst case scenario pick up some maf cleaner, spray gently on a rag and wipe on the maf, then dry with a microfiber cloth

Maf cleaner, you dont want to put other chemicals on the sensor or touch it.
