Just bought 06, 57k miles. Dealer told me their porsche certified mechanic went through the car and it has no issues. 
When the car arrived, we scanned it: missfires p0300, pasm failure 5400. On top of that, navi is stuck on “starting navigation” and wont move, ive even done reset, nothing. Dvd looks nice and clean. Panel was painted, engine mounts are shot, idler pulley on the way out, windshield wipers were worn to ****, scratched the windshield, rms is peaking, leaking axel boot, right wondow auto up doesnt work, etc

we reset the codes, pasm comes back, cel is intermittent. 

 

I did searching, but not finding specific answer. 

 

Yesterday, when i stalled the car, and restarted it, the engine jerked and pasm error went away for the whole day. Next day it came back, and still there. 

 

Diagnostic is a lot of money, so im trying to see if its perhaps a loose contact somewhere (that engine jerk maybe shaken something back into place). Can someone tell me where are the pasm connections and if there is anything i can tug on to see the right fit?

Welcome to RennTech :welcomeani:

Now you know why we recommend a full pre purchase inspection by an independent shop.

 

Misfires are probably coils and/or plugs.

 

The P5400 is a “sport mode” fault that will require diagnostics with a Porsche specific scan tool to determine what is going on.

Thank you for pointing out ppi. This is not the first car i bought, and am well aware of the ppi. Ive been on a hunt for a car for few months, and the previous one that i narroved down, i paid for ppi and walked away from the car. Another 2 cars dealers sold the car before we could get ppi done (had ppi scheduled and dealer sold before it could be done). I needed a car. This dealer stated they have porsche certefied mechanic on staff, they deal with selling some exhotics and lots of high end cars. The car met all my criteria in options (manual, chrono, sport seats, aero package, black on black). The dealer assured me multiple times the car is in tip top shop, and I even noticed bad oil pressure in pic, so mechanic fixed that before car got on delivery truck, and he again told me the car was perfect. Car had clean car fax, recent clutch job (documented on carfax). 

Ps. Im a long time member on pellican (i have an 88 carrera as well) and other forums. No newb to car world. 

 

So please, spare me. It hurts as it is. Now i need to get this fixed. Im trying to work with the dealer, but as of now its a dead end. I had an article posted by jalopnik and i will be doing more social media involvement on this issue, but at the end of the day, the car needs fixing. 

 

On the cel: ordered all new plugs, and ordered 3 coils (scan shows missfires on left side). Hopefully next week i can get the car in. The shop i use has one techie that can do computer scans and figure it out, but perhaps its something simple that i can myself tinker with? Is there any connections to pasm unit in the engine bay?

To my knowledge, there are no connections for PASM in the engine bay.  Unless your “techie” has one of the Porsche specific diagnostic systems, he won’t be able to help you as the systhem controller uses proprietary Porsche software.

It makes me nervous if I understand that the shop you use only has one person that can scan codes.  To work on your car you need a PIWIS or 3rd-party Porsche-specific tool like Durametric.  Scanning with a generic tool can work but sometimes gives incorrect/misleading information.  Not using the proper tools can be expensive in time and money.

 

I'm sorry this happened to you.  Unfortunately most people selling cars aren't honest, including -- if not especially -- dealers.  And the way the laws are setup, once the car/money trades hands you have very little recourse.  People trying to sell a car conveniently "forget" things or embellish/exaggerate in their own favor -- they want to sell the car and, maybe I sound cynical here, but most people are just disingenuous.  You can't trust them, especially when there's money involved.  They will look you right in the eye and then lie through their teeth.  Dealers are in the business of moving cars, the longer it sits the more desperate they are to move it.  I've seen so many cars with issues try to be passed off as "clean as a whistle!", it's an embarrassment.  While advisable, even an independent PPI isn't a guarantee.  It's just a sanity check that when someone (who hopefully is very familiar with the ins/outs of these cars) scans codes and gets it up on a lift, there are no glaring issues.

 

I wish you luck.  If you end up just needing some new plugs and coils, and a couple other things it won't be the end of the world.

I should have been more clrea, the techie actually does have duramac and is versed in dealing with porsche’s. I should have said that. 

 

At the end of the day, its just money, i get that. It just really ruined my porsche experience ? i even wrote to porsche, to ask them how can a porsche certified mechanic give this car a green light. The car came off delivery truck with pasm and cel right on the dash! Just complete bs...

I know you know now but it's always best to go see the car and drive it there.  Trust but verify.  Even if the mechanic went through the Porsche training program and got certified (I believe there are different levels as well), if they are now working at an independent dealer outside of Porsche and are dishonest or sloppy, I doubt Porsche has any recourse.  Even if this happened directly from a Porsche authorized dealer you would still have issues as the laws simply are not setup in your favor -- once the money trades hands it's a done deal.  However at an authorized Porsche dealer I would think the likelihood of something like that happening would be much less.  Used car sales though is a shady business.

 

I have bought a car in the past and missed things even though I knew exactly what to look for, picked it up in person, and had a PPI done at a Porsche dealership, got a carfax, etc, etc etc.  I crossed my t's, dotted my i's...and still got burned.  Some things like a CEL or stored codes are easy to catch.  Other issues can be much more subtle or intermittent and make it hard to spot.... even for someone that has the knowledge of what to lookout for.

 

Also ya I did mean it's just money but the cost of plugs and coils isn't as bad as some of the things people have been scammed on.  There is no end to the crazy stories and lies you hear when looking at used cars.  I tried to buy an Audi Q5 last summer and threw in the tower and bought a certified one from Audi.  Too many idiots and liars out there selling cars.  Sad state of affairs really, but you can't trust most people.
