Hi,
I own a
2011 Boxster S
987.2
with around 20k miles.
Few weeks ago, was returning from the coast and a white transmission error message showed up.
After 2 weeks searching, the mechanic is blaming a faulty MAF sensor, which according to my research sort of makes sense (though no CEL light).
The problem is: the guy is killing me with the price.
He wants to charge for 8 hours of labor plus the part, total around US$1.8k. Note I live in Brazil so parts are really more expensive but anyway he’s charging a big markup (50%-100%).
In your experience, are 8 hours really needed to replace a
987.2
MAF sensor?
Appreciate your help!

Did you try a Google search for book time for that repair? Surely something must be listed.

No, not if he knows what he is doing and not just learning at your expense. I am just a guy handy with wrenches and I did it in an hour. It is a little tight to get at but so are most things on cars. Mine just needed to be removed and cleaned with MAF cleaner spray. I was getting a code about some improbable air flow (not exact diagnostic wording but close). I'm not sure how the MAF reading plays with PDK, but I won't argue that diagnosis.
The MAF on a 987.2 is replaced as a unit with the housing between the air filter box and the intake plenum. So the whole housing needs to be replaced. Older engines you could just remove a couple screws to pull just the MAF out of the housing - leaving the housing alone.
Update: I have a Cayman and I see you have a Boxster but I doubt it makes much difference. Maybe a little tighter access in your case.
8 hours labor seems nuts.
As noted above you should just try cleaning yours with spray MAF cleaner first. On the
Cayman
it's a tad difficult to get the MAF out of the car. But cleaning it without complete removal is not too bad: just disconnect the hoses and electrical connector, spray it down with cleaner in the car, and then reconnect everything. It's probably similar on the
Boxster
.
Thanks guys. Yes, I did do a search and found that 8 hours seemed excessive.
Was chatting with some guys at the local
Porsche
group and there were some arguing that the mechanic needs to charge for the hours it took him to discover… which to me only makes half sense, it’s like rewarding the less knowledgeable/efficient mechanics.
Think I’ll have to discuss with him. I already told him that I’ll be in the US soon and if needed will buy the parts there.

Typical diagnosis time is 1.0 hours unless tracing down electrical issues, so I can't see why it would be more. Modern vehicles you can run a scan for fault codes and that generally points you to the faulty component. Running that test actually takes a minute or so so generally that diagnosis fee is very generous.
