2013 Porsche 911 Carrera Cabriolet: Check Engine Diagnosis

May 17, 2013

2013 Porsche 911 Carrera Cabriolet

I took our 2013 Porsche 911 Carrera Cabriolet to our friends at Beverly Hills Porsche. And like some kind of automotive Dr. House, assistant service manager Erik rendered a probable diagnosis without even looking at the car.

"I know what it is," he said: the tank leakage diagnostics module. It's malfunctioning, and apparently a bunch of 911s of the 991 generation are having this issue. The parts are on order and should take a week to arrive. Erik says the car is good to drive in the meantime.

That's a relief. It's supposed to be a nice weekend.

  • ryster ryster Posts: pay $100K for a Porsche and the assistant service manager diagnoses MIL's without even looking at the car? Hopefully there is more to this post and the car was properly diagnosed by a tech with a scan tool who later confirmed the originally "divined" diagnosis. If it were my $100K car, I would have had a major issue with the assistant service manager taking it upon himself to guess at the problem without even looking at the car. My 2011 Hyundai Sonata is nowhere near as advanced as this Porsche, and the techs always scan for codes before diagnosing any issues (luckily only 1 issue in 41,200 miles of ownership.) The Hyundai Service Manager even confirmed that a scan would be done to determine the issue. That is how it should be done.

    @ryster... settle down. it's a known issue and the guy knew what needed to be done. why waste the customer's or the service tech's time if it's unnecessary?

  • @zcalvert- I am sure Mr. Lachnit had the car scanned and simply forgot to state this in the post. I do agree with ryster though, as far as not taking the Porche tech on his word. If it was me I could not be comfortable until I saw proof that this simple

    Sounds about right. To those crying...a BRAND NEW model barely ever sets off MIL so soon unless there's a flaw in production. If there is, the techs (and service writers) get used to the cars coming back and dont really need to "scan it". If the vehicle had any real problems there would be driveability complaints and the MIL would be flashing instead of just illuminated.

    I've looked at several 2012 911s (991s) that had a few miles and were certified. Figured it might be a way to save some money and get the longer warranty. I love the cars but a review of the car fax documents shows that the cars have had NUMEROUS recalls and this tank leakage module is just another example of problems with a new model. We've all heard it before, don't buy the first year of any new model, and it appears to apply here as well. probably best to wait for 2014s to let Porsche get the details figured out.

    Oh, for Christs' sake - two posts to tell us it has a CEL, but you haven't bothered to pull the codes. Now another post to tell us the service manager got the problem by osmosis. I dunno - they just act like they're never owned a car before or dealt with a dealership. If a week goes by, the parts come in and are installed, and there is still a code, I would be on that service manager like white on rice.

    Teething problems do arise, but they know what the problem is so no harm, no foul. My Mom's 2011 Cayenne was the 1st year of production (DI engine, 8 speed automatic) and has been absolutely bulletproof in 50K miles. My 2011 BMW 328xi (in it's 7th year of production, E90s came out in 2005) has a recall, a faulty trunk latch, and a passenger side adaptive headlight that lights up the tree tops. Does that make it a bad car? Not at all. Things happen, that's why cars come with warranties.

    German is to electronics as Greek is to hard work.

    Look, it's a diagnostics module in a German car, which means it's probably made by Bosch or Continental - both companies with very good reputations. Bad batches of parts occasionally come from every supplier. Sucks for the owner, sure, but it's just the way it goes sometimes.

    @zcalvert Germany seems to have developed a penchant for this stuff just lately. Ask a bunch of recent BMW owners about high pressure fuels pumps. Hint: wear Kevlar.
