Simple solution that saved me a potentially expensive garage visit
Here's a detailed review for the LIQUI MOLY Air Flow Sensor Cleaner:Simple solution that saved me a potentially expensive garage visit⭐⭐⭐⭐⭐My car had been experiencing rough idling and occasional stalling, symptoms that typically point to expensive engine diagnostics and repairs. Before heading to the garage for what I expected to be a costly investigation, I decided to try cleaning the mass air flow sensor myself with this LIQUI MOLY cleaner - and I'm glad I did.Effectiveness and results:The transformation was immediate and impressive. After spraying the sensor according to the instructions and letting it dry, the rough idling completely disappeared and the engine returned to smooth operation. What I thought might be a major engine issue turned out to be simply a dirty MAF sensor that this cleaner handled perfectly. The car now runs as smoothly as it did when newer.Ease of use:The process couldn't be simpler - locate the sensor, spray, wait for it to dry, and reassemble. The 200ml can provides plenty of product with a precise spray pattern that makes it easy to target the sensor elements without oversaturating. Clear instructions on the can help even novice DIYers feel confident about the process.Value proposition:At under £10, this saved me what could easily have been a £100+ diagnostic fee plus labor costs at a garage. Even if you only use it once, the savings are substantial. The can contains enough product for multiple applications, making it excellent value for money.Quality and reliability:LIQUI MOLY has a solid reputation for automotive chemicals, and this product lives up to that standard. The cleaner evaporates cleanly without leaving residue, and I've had no issues with sensor damage or performance problems after use.Practical considerations:The spray can is compact and stores easily in a garage or toolbox. The product has a reasonable shelf life, so you can keep it on hand for future maintenance.Bottom line:This is one of those products that can save significant money and hassle. If you're experiencing engine performance issues that might be MAF sensor related, this is definitely worth trying before expensive garage diagnostics. It's become a permanent addition to my basic car maintenance toolkit.

This product works & could save you a small fortune...
Excellent product, works just as described. I was having problems with my car's engine (Volvo 1.6 turbodiesel i.e. the notorious 1.6 PSA diesel) routinely going into limp-home mode or cutting out completely when hitting 3,000 RPM, and due to the car's mileage (66k) my thoughts instantly turned to potential DPF issues. After visting a local garage for a diagnostic check, they couldn't identify the problem but suggested either clogged injectors or the DPF might be the cause, both of which could prove costly to fix. They recommeded using some DPF cleaning additives first, but after trying this it didn't seem to make much difference (other than my MPG dropping slightly)I wasn't wholly convinced, and after purchasing an OBD II diagnotic reader (also from Amazon, which worked perfectly - look for the reader sold by "RisingTech" if you are interested), the codes it brought up directed me towards Air & Fuel Sensor issues. I then visted some online Volvo forums & discovered a common issue which caused similar symptoms was the Mass Air Flow sensor getting contiminated. In most cases the sensor just needed to be cleaned rather than replaced, and several forum users recommended Liqui Moly's air flow sensor cleaner.Finding the product on Amazon UK for £10.33 (which, at the time of writing, is significantly cheaper than elsewhere), I was further reassured by the number of positive reviews, so I figured why not try it? After purchasing the cleaner & cleaning the sensor (a bit fiddly to remove but with some patience it was straightforward enough), my car is running superbly, pulling under acccelaration with no hesitancy at all (unlike before) and the MPG is back up to what it was previously. Although the product is small (200ml) a little goes a long way and you don't need to use a great deal. Just make sure that after cleaning the sensor, you let it dry off for approx. 30 mins before putting it back in.So if you are having similar issues, I would fully recommend trying this first before going down a potentially far more expensive route.
