After being stung by OPC prices the first time, my most recent one was replaced by Northway (indie Porsche specialists) near Reading for about half of the OPC price and no labour charge.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Am I just unlucky in facing a second Air Mass sensor replacement on my 1999 996 C2? In 25 years of Golf GTIs I only had to replace one. I had my 996's sensor replaced in 2008 at 47k miles at a part only cost of c.£450. Although running well at the last service in Feb at c70k miles the diagnostics flagged up that the sensor wasn't 100%. I'm living with it at present!

POST 2Original post

Do you have a non-standard air filter e.g. K&N? Dave Jones

POST 3Original post

+1. Also, check out other sources for the MAF. Euro Car Parts, Type911, Design911, etc. you will find them at less than half the OPC prices, and it is a 10 minute job to change one. You just need a Security Torx bit. T20 iirc.

POST 4Original post

There is one on Ebay at the moment in Germany that is quite cheap. Genuine new Bosch part. Alasdair

POST 5 / ORIGINAL POSTEROriginal post

Hi Thanks for quick replies: My Air filter is standard. The car has been fully serviced on the dot by PCT since I bought it in 2004 with 27k miles on the clock and full OPC service history before then. Dick Morgan

POST 6Original post

Sounds like you're just unlucky, unless it was damaged during installation? If it's just become dirty it's possible to clean it very gently.

POST 8Original post

Air mass sensors have failed on both my 996s. They seem to be a weak component. After being stung by OPC prices the first time, my most recent one was replaced by Northway (indie Porsche specialists) near Reading for about half of the OPC price and no labour charge.
