Liqui Moly Car Maintanace Cleaners and Fluids (Air Flow Sensor Cleaner)

Excellent and as website description

its clearing the mass sensor perfectly without any issues

By far it’s the best you could get for the price point. With few simple sprays, all the dirt came off and it dried in few minutes and afterwards it showed a small increase in economy

Good

perfect

This product really works , used on a Lexus LS 430 car is definitely more responsive and pulls stronger. Recommend using this product whenever you can see dirt on the maf sensor

Very good and cleaned my air sensor very well from the first time untill now still perfect

Overpriced but doing good

Den LIQUI MOLY Luftmassensensorreiniger (Art.-Nr. 4066) habe ich bei einem Fahrzeug mit leicht unruhigem Leerlauf und minimal erhöhtem Verbrauch eingesetzt. Der Luftmassenmesser ist ein sensibles Bauteil – entsprechend wichtig ist ein spezieller Reiniger, der rückstandsfrei arbeitet. Anwendung Ausbau des Sensors, vorsichtiges Einsprühen mit etwas Abstand – mehr ist nicht nötig. Das Spray ist farblos, trocknet schnell und hinterlässt keine Rückstände. Wichtig: Nicht mechanisch nacharbeiten, kein Tuch, keine Bürste. Einfach einsprühen und ablüften lassen. Wirkung Nach dem Wiedereinbau lief der Motor gleichmäßiger, insbesondere im Leerlauf. Auch das Ansprechverhalten beim Gasgeben wirkte spontaner. Natürlich ersetzt das keine Diagnose bei echten Defekten, aber bei Verschmutzungen durch Ölnebel oder Staub kann die Reinigung tatsächlich helfen. Qualität Typisch LIQUI MOLY: saubere Verarbeitung, gut dosierbarer Sprühkopf, keine aggressive Geruchsbelastung. Man merkt, dass das Produkt auf empfindliche Elektronik abgestimmt ist. Einordnung Der Luftmassenmesser beeinflusst Gemischbildung und Verbrauch maßgeblich. Eine regelmäßige, sachgerechte Reinigung kann daher sinnvoll sein – insbesondere bei älteren Fahrzeugen oder nach stark verschmutzten Luftfiltern. Kein Wundermittel – aber ein professionelles Serviceprodukt, das bei richtiger Anwendung eine technisch sinnvolle Maßnahme darstellt.

I used this spray for my Verna diesel MAF sensor which has not been cleaned since purchase around 16 years. The product is original and packaging was good n I thank Amazon for that. After spraying, the sensor became 100% clean n there was no traces of carbon or grime and engine drive was very smooth. I thank Amazon once again for delivering such an excellent product.

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.
