An error indicating that the air mass meter is faulty, which is quite common for the E39 M5, is twice as bad for a the driver of that M5.
Why? The M5 has two air intake hoses it also needs two air mass meters.
Though this is the engine of a E60, you can see how it has two airmassmeters
Often only one of the airmass meters is actually faulty though. You can save some money by just buying one air mass meter and trying out which one is really broken. Continue reading »
The MAF Shop just released an English version of their video about air mass meters. It gives you a quick general explanation about airmassmeter and installation instructions.
The Pierburg air mass meter 7.22684.08.0 has been quite a popular replacement of the Bosch air mass meter used in many of Volkswagen’s TDI engines, which is known to be susceptible to faults.
Except for a few exceptions the 7.22684.08.0 mainly fit for the 1.9 TDI used by Audi, Seat, Skoda and VW. However, there was no airmass meter replacement equivalent to Bosch’s quality for the 2.5 TDI, FSI and 1.8 T (exact vehicle list).
Finally Pierburg offers now also an air mass sensor for those models, called 7.22684.10.0. Same as the 7.22684.08.0 the 7.22684.10.0 uses a very precise hot-film sensor which is quite more accurate and durable than the cheap Asian replicas and much cheaper than the Bosch airmassmeter, which costs >200€.
The MAF-Shop offers the Pierburg 7.22684.10.0 airflow meter for €99.90 incl. taxes (+shipping):
The MAF-Shop offers now an OEM airmass meter by Pierburg (7.22184.50.0) which fits the 2.5 l turbo diesel (td) and intercooled turbodiesel (tds) engines, that were used in the BMW (M51D25) E36, E34, E39 and the E38, as well as in the Vauxhall (also known as Opel) Omega B (25DT).
Especially the 5-series E39 525tds, 525td and the 3-series E36 with the 325td version, were some of the most popular BMW diesel models, so I’m sure a lot of the turbodiesel-enthusiasts will be happy about this cheap offer:
The PIERBURG MAF 7.22184.50.0 costs €179.90 (+shipping cost) and can be ordered through this link:
The MAF Service GmbH - the company behind the MAF-Shop - is situated in Berlin, the capital of Germany, but distributes their air mass meters worldwide.
Their website and customer service is available in German, English, Spanish and French.
But how does it work when you order an airmass meter from somewhere else in the world?
The payment process via credit card or PayPal is pretty much possible from anywhere, bank transfers are also available - in the EU they’re even for free.
Also, if you have the air mass meter shipped to somewhere outside the EU, like the United States, Canada,… the German VAT is automatically deducted. That’s 19%!
For example, the Bosch air mass meter 0280 217 114 which fits a lot of Mercedes models, costs instead of 199.90€ only 168€ (you divide the amount including VAT by 1.19 to deduct the German VAT, don’t worry though, the online shop does it automatically for you).
If you want your air mass meter to be delivered within the EU and you have a VAT ID, like most business in the European Union do, you can also deduct the 19%.
The main shipping courier that is used, is DHL which delivers almost to anywhere in the world and is pretty cheap. Here are the details, but let’s have a quick overview:
Shipping within the EU (UK, Netherlands,..) costs 8.90€ and take 2-3 business days.
Shipping within Europe costs 12.90€ and take 2-4 business days.
Shipping to the rest of the world costs upto 32€. Inquire for more details. Especially to the USA cheap and quick shipping via FedEx is available.
Don’t forget that you might have to pay customs if you have the air mass meter shipped somewhere outside the EU.
A few years ago some Volkswagen freaks experimented with replacing the Bosch air mass meter of their 1.9 liter TDI engine with the much cheaper Pierburg air mass sensor 7.22684.07.0, which is the Genuine air mass meter for almost all Mercedes-Benz CDI’s and noticed that the engine worked just as fine as it did with the Bosch MAF. Another advantage than the Pierburg airflow sensor being much cheaper was that it lasted much longer.
The only problem that the VW enthusiasts encountered was that the Pierburg air mass 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. Continue reading »
Since there has been a lot of confusion about the Bosch air mass meters 0 928 400 527 ( and 0928400468) and 0 928 400 314, I want to explain the details.
For almost all BMW models with diesel engines (to be more exact, we’re talking about the 3-series/E46 320d, 330d, the 5-series/E39 520d, 525d, 530d and the 7-series E38 730d) the airflowmeter model was changed in November 2000 and August 2001.
The Bosch air mass meter 0928400314 was replaced by the improved 0928400468, which has an additional protection net and a different characteristic curve. This means that all models that were built before the dates have the old 0928400314 (there is a detailed list at the end of the post). Continue reading »
Many customers tell us that friends or internet forums recommend to clean the air mass meter with cleaning chemicals designed for removing brake dust or other cleaning solvents.
It should be said that these customers contact us anyhow to buy a new airmassmeter.
Why should the cleaning process work anyhow? The most common reason air mass meters lose their performance or even stop working at all is that they slowly get dirty. That is also why most of the time you will notice a slow loss of performance and increase in fuel consumption (In case your airflow meter should abruptly stop working cleaning won’t help anyways).
Hey guys and girl, welcome to our Air Mass Meter-Blog!
We’re one of the leading experts for air mass meters and will try to share all our knowledge with you about car parts.
We will be mainly translating the (awesome) blog posts of the German Luftmassenmesser-Blog, which has a huge load of information about car parts for German cars like BMW, Mercedes and Volkswagen (or Volkswagon as Americans would say).
So start up your engines and get ready for some cool blog posts
