Used this to clean my MAF sensor - I have a Bosch VAG sensor (used in probably tens/hundreds of VAG models circa 2004) and I was suspicious of an issue due to rough idling - everything else was fine with the car. Unplugging the sensor brought the car's idling back to normal so I was suspicious of the MAF sensor, having never cleaned it in the 9 years I've had the car.Before ordering a new Bosch MAF sensor (they're quite costly) I took my existing one out, and then removed the actual sensor carefully (attached with two special keyed torx type screws) - I gave the sensor a direct spray very carefully - notably the metal wire that does the sensing - very delicate area. I then gave the whole MAF enclosure a spray and clean too. If I'm honest not a lot of black dirt came out of my setup but once all reassembled, this rectified my idling issue. I was initially not able to see the wire clearly as it was coated in black slightly, but once sprayed and clean it was visible again - no doubt that was the issue.But trying to spray this sensor directly whilst attached within the MAF pipe enclosure would have been impossible and wasted a lot of this spray no doubt so ensure you've got your sensor disassembled and you're working directly on the sensor wires - but be careful!Saved me the purchase of a new MAF sensor and I'm convinced that this is the issue with most of you with idling issues - existing sensor just needs a clean, not replacement. And always good to start down that avenue.

Used it everything seems to work fine would buy again and recommend

I had to use it twice in succession to get the result I expected.

Whilst I am confident that it did clean the dirt from the sensor, unfortunaly I suspect the condidtion of the unit was worse than suspected as it performed very poorly afterwards and had to purchase a new unit. It it was over a £110.00 so it was a good spend at £8.00 to have a an attempt. If it had worked in my case, I would have been over the moonI will keep the can as use each time I charge the air filter, it might just expeded the life of the sensor pass 50k miles

Well made and easy to use great item
