The solution for TDI engines: Pierburg caeli massa metri 7.22684.08.0
A paucos annos quidam Volkswagen freaks experirer cum reponat Bosch caeli massa numerus eorum 1.9 sextarius TDI machinam cum multo vilius Pierburg caeli massa sensorem 7.22684.07.0, quod est Sincerus caeli massa metri fere omnes Mercedes-Benz CDI scriptor animadvertit machinam laboraverunt ut denique ut fecit cum Bosch MAF. Alia utilitas quam Pierburg airflow sensorem multo vilius erat quod duravit diutius.
Solus forsit quod VW fanaticus congressi erat quod Pierburg caeli massa sensorem 72268407 non vere apta quia plastic habitationi erat a frenum diversis ad originale caeli massa metri. De cursum, pecuniam facit creatrix et omnes genus praestigias sunt solebat in sensorem in loco.
The housing manufacturer of Pierburg’s sensors picked up on the idea and asked Pierburg if they didn’t want to change the housing and introduce an air mass meter that would fit. In Pierburg caeli massa sensorem 7.22684.08.0 was created!
Per viam, I’m referring to the Pierburg part as “air mass sensor” instead of “air mass meter” because other than the Bosch air mass meters which include the sensor and the housing, it is only the insert which is screwed into the housing (take a look at the pictures for a better understanding).
The Pierburg airmasssensor is to the current day still very popular, even though Volkswagon changed their price policy for their Bosch air mass meters after a lot of car magazines started reporting about the worldwide problems with the Bosch air mass meters and it wasn’t just a problem of a few individuals.
As I already mentioned, many forum members report that the Pierburg MAF sensor works better the OE air mass meter. Some even say that they notice an increase in the car’s performance, but I haven’t found any technical comparisons that confirm a performance boost.
In addition, the Pierburg part is still much cheaper (around 50% less!) than the Bosch airmassmeter.
The MAF-Shop offers the Pierburg air mass meter 7.22684.08.0 for €74.90 including an installation kit and a type approval by the German TÜV (Technical Inspetion Authority).
You need that installation kit because the old Bosch airflowsensor is screwed in with special torx bits which you normally only car repair shops have.
Why so complicated? Maybe Bosch was already suspecting that private owners would replace the airflow sensor instead of going to the Volkswagen repair shop.
Well, screw Bosch (literally, 
), the installation kit includes everything you need (torx bits and even a screwdriver).
Replacing the air mass meter with the Pierburg sensor is really simple and takes around 5 minutes – no need for reprogramming the ECU or stuff like that. Watch this video’s to see how easy it is:
Which TDI’s work with the Pierburg air mass meter?

The most popular models include the Golf IV (4) TDI, the Audi A3 TDI and the Skoda Octavia, each with the 1.9l TDI (Turbo diesel-injection) engine, there are also a few models of the VW T4 bus with the 2.5 TDI motor that work with the Pierburg air mass meter, but check back with the car list for more details. There is even a few Ford models that fit.
