LIQUI MOLY Air Flow Sensor Cleaner | 200 ml | Service spray | SKU: 4066

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.

Used this on my MAF sensor after noticing rough idle and sluggish acceleration, and the results were immediate. The cleaner evaporates quickly with no residue and was very easy to apply. After reinstalling the sensor, the engine ran noticeably smoother and throttle response improved. What I like most is that it’s specifically made for sensitive air flow sensors, so I felt much safer using this compared to generic cleaners. The spray nozzle gives good control, and one can should last multiple uses. Excellent product from LIQUI MOLY — highly recommended for preventative maintenance or troubleshooting MAF-related issues.

Did what it said on the tin and made a good job of the air flow sensor

I guess it’s a good product as it stops residue from petrol or brake cleaner which is apparently a problem but the issue with mine turned out to be a loose MAF sensor plug. My car wouldn’t start sometimes and would sometimes cut out. Some cars rely on the MAF to run at all

excellent

Excellent product, spray allow to dry refit the sensor and drive away immediate change in engine running and fuel consumption noticed.

Maybe it’s just me, but the car really does drive better after the cleaning.

mpg went up from 32 to 35+

👍👍👍👍👍👍

Produit conforme à la description et facile à utiliser. Je l’ai utilisé sur ma Prius 2 pour nettoyer le débitmètre d’air qui causait l’allumage du voyant moteur. L’application est simple : quelques pulvérisations suffisent, sans démontage compliqué. Après utilisation, j’ai redémarré la batterie comme recommandé, et depuis, plus aucun voyant moteur ne s’est allumé (cela fait maintenant 5 mois). Le moteur tourne plus régulièrement et j’ai même remarqué une légère amélioration de la consommation. Ce produit m’a permis d’éviter un passage au garage et donc une réparation potentiellement coûteuse. Très bon rapport qualité/prix, je recommande.

Excellent and as website description
