miaka michache iliyopita baadhi freaks Volkswagen majaribio ya kuondoa Bosch hewa ya molekuli mita moja ya zao 1.9 lita TDI injini na bei nafuu sana sensor Pierburg hewa ya molekuli 7.22684.07.0, ambayo ni Genuine hewa ya molekuli mita kwa karibu wote Mercedes-Benz CDI na niliona kuwa injini ya kazi tu kama faini kama alivyofanya kwa MAF Bosch. Faida nyingine ya Pierburg airflow sensor kuwa nafuu zaidi ni kwamba ilidumu kwa muda mrefu zaidi.

Tatizo tu kwamba enthusiasts VW yaliyojitokeza ni kwamba Pierburg hewa ya molekuli sensor 72268407 didn’t really fit because the plastic housing was a bit different to the original air mass meter.  Of course, money makes people creative and all kind of tricks were used to keep the sensor in place.

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. Pierburg hewa ya molekuli sensor 7.22684.08.0 was created!
Kwa njia, 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 dakika – no need for reprogramming the ECU or stuff like that. Watch this video’s to see how easy it is:
