I expect this has been talked about numerous times, but took my MAP sensor out today - pretty gunked up! But is a 2 min job (exc drying) that the vast majority could do themselves. Shame they're too sensitive to shove a cotton but in there; there is definitely a bit of residue left on the metal sensor at the bottom of the hole. But far less.

Haven't got it back in yet to see if there's a difference. MAFs next.

I dread to think what the rest of my intake looks like 🤦‍♂️.

Anyway posting this to encourage other nervous DIYers to have a go (diligently)

Wow, that surely will make a difference.

Looks very worthwhile. I dread to think what signal that sensor was sending 😲

Yeah, contact cleaner will do. MAF just need cleaning with something that leaves no residue ie high alcohol content.

Well I took my car for a drive for the first time since cleaning the MAP. I think a very slightly better throttle response. Something more noticeable is that i'm convinced the second turbo is kicking in earlier, but that surely can't be a thing (other than my imagination 😆).

Oh also at idle on the OBD my engine load is now lower from 23% pre-clean to 19% post-clean (same temp, idling time etc) 🤷‍♂️

China's finest I bet!

Cheap is not always good though.

Personally, sensors, I spend a bit more money on and buy something branded and NOT from ebay. You just simply can't trust the source on ebay.

I have bought sensors ftom ebay before, for wife's Q7....yes it was the cheapest option....but it simply did not work. I think it was the air quality sensor.

Go cheap, pay twice!

Any alcohol based spray will suffice 👍
