MAF sensor, 2nd time in a week

Also, make sure that AFTER you get the actual problem fixed, you cancel the charge to your credit card, and tell the Stealer that they did not fix the issue, so you are not paying for a repair that was pointless.

I didn't manage to get the codes either, but will do so when I bring my car in tomorrow. Gent, am interested in comparing stories with you after your visit to Vancouver West.

So, not a MAF problem in my case. I asked them to drop me an email with the details, since we were all in a rush when I picked up the car. Obviously, I didn't do the Inquisition thing either, lol.

Forgive any paraphrasing I do here. The code behind my CEL had to do with a perceived low airflow that apparently barely registered, but tripped the CEL and would likely have cleared itself shortly anyway.

They went through the car top to bottom, including running a test with a couple of psi in Nitrogen designed to help them find any leaks in the system (which the car passed).

Once they were satisfied, they reset it for me, gave me a call and I picked it up. No charge.

I'm not an automotive neophyte, and I still say this is a good shop with knowledgeable staff and ethical management.

I'll get the details (probably tomorrow), and post them.

Legume, maybe you can get Alfred to lay out (in an email) what they checked and the options for you? I know he throws out a lot of info very quickly. I highly doubt that the work was poor or that you are being taken for a ride.

Info:

"The fault code recorded on your boxster was mass airflow circuit low input.We checked data blocks using a canbus enabled test tool and found mass airflow meter readings fluctuating at 2.85-3.2 grams per second of air flow recorded.This reading is correct for your meter type (986).Maybe pinning the rev limiter and cutting fuel flow (full throttle and rpm drop simultaniously?)caused low mass air reading .All other vacuum sources tight and sealed so we monitor further."

The car is still with Vancouver West, they're going to keep it overnight but they think they've found the problem. Was told that the PCV breather filter assembly is cracked and that's where the oil is coming from.

BTW, I checked my invoice from last week and it turns out that Alfred did list the error codes: DTC 1128 and DTC 1130.

Will keep you posted.

Looks like a failed AOS causing your car to run lean. Have them replace the AOS if it is visually cracked or leaking. The MAF and O2 sensors were probably fine all along and they just missed the AOS problem. $810 oops.

Legume, I'd print this out and bring it in to them so that they can address your concerns. I look forward to reading the answer.
