Advice for buying 2K Boxster with P0410 P1411 codes - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Is it worth to considering? The owner has already tried to repair this as they have - Replaced all 4 oxygen sensors - Replaced all vacuum hoses and IMS Obviously the above didn't take care of it. Thoughts? TIA

Just one: Don't. Codes are for a failed Secondary Air Injections system, which can be pricey to repair if you don't do it yourself. Car will not pass emissions as it is.

Sup! I actually bought a REALLY nice 99 boxster myself that had these codes. The owner didnt know what they were and I actually paid 4.5k everything else was absolutely mint. As JFP mentioned it CAN be pricey so just keep that in mind. For me, I was quoted $1,200 at a local German Shop to do a full replacement of the secondary system. However I did diag myself and see that the MAF sensor caused it. no leaks. no code after all good. It can vary per car but it was very simple for me. If you do buy it, Id recommend doing a vacuum leak test. In my own experience it was a simple diag and replacement. If you do the job yourself it CAN be alot cheaper than even what i was quoted to replace the full thing. For the price, I think itd be a good buy IF you thoroughly checked everything else and it checks out nicely. Side note: With the owner attempting to repair. It doesnt seem like he really tackled the MAIN issues that can come with these codes. Typically when these codes come up, the first things to look at are the vacuum reservoir (with age, they can lose integrity and no longer hold vacuum. They are also $30-$40 on ebay), and 'Pump' Change Over Valve. In most cases those will be the largest culprits of the codes. If not an old leaking hose.

Thanks for the input guys!

A Boxster for 2K? I typically buy boxsters in this price range with a blown engine. Fixing the SAI is a minor thing compared to the really expensive issues that should make you run away, like timing chain failure, bore scoring, etc. If the rest of the car is fine it's worth it. Fixing the SAI is not expensive at all if you do it on your own. You can replace the whole thing for a couple hundreds in parts. But if you want to get something like that fixed by a mechanic you should not consider buying a car like this for 2K because probably that's not the only problem you'll be facing.

I think he was referring to the car's model year, not its price.................

Hmmm, you may be right, I hope he clarifies. In that case, the cost of fixing the SAI will need to be incorporated in the price, but it still can be a great deal. He also should be aware that he can't transfer on his name right away, unless he puts it in non-op. He can get a temporary permit and drive it for two months I think until it can get smogged. My current car was like that, was pretty beat up and had a bunch of codes which took me two months to get rid of.

👿 grrrr…. I just had these codes come back after a 1yr hiatus. I’m declaring war on the SAI.

Same here. There haven't been any codes for almost two years, I was bored.

We had/have? a member who invented a device to be wired in that would render the SAI virtually invisible... bypassing everything... and passing smog. I had read enough about the SAI when I purchased my car in '17... that I bought one. It remains stored away until necessity calls. In the event of my death, and before install, I "sharpied" on the box in which it's stored what is in the box... and a price suggestion so that my wife can profit. OP... what is the asking price for the car... and just use numbers.
