There is a lot of confusion about the airflow meter with the label >PBT-GF30< and the reason why you are reading this article is probably because this is exactly what it says on your air mass meter…
The reason you haven’t found a dealer where you can buy this part is that PBT GF 30 is not a model or part number but the abbreviation for Polybutylene terephthalate and 30% glass fiber, the plastic used in all air mass meter housings – regardless of whether it’s Bosch, VDO or Pierburg.
So, how can you find the correct part number of you air mass meter?
Often the actual part number is on the other side of the housing. Sometimes this is exactly the side you can’t see when the unit is still installed, so you will have to dismount it from the air tube which takes approx. 5 minutes (check the air flow meter installation video to see how it’s done).
Also, at the MAF-Shop you can find the correct airmassmeter by choosing your car model. If you’re not sure, you can also directly contact customer support via email to inquire which air mass meter will fit your vehicle.
