    You need to take equal amounts of both sides of the gap to obtain the final clearance. We use a Total Seal unit to do this: But you can use a simpler hand tool like this to get to the same place:

    The immobilizer under the seat is coded to your keys and the DME, it cannot simply be changed out, it requires coding with a PIWIS or PST II.

    Welcome to RennTech On cabriolets, the number 2 relay panel is mounted to the rear of the roll over protection frame. You need to put the top in the "service" position to gain access to it.

    I would look at the O2 sensor voltages before and after the main cats, and would also check the fuel trims. A lamda of 1.0 would have the engine running at an air/fuel ratio of 14.7:1; if the lamda is above 1.0, the engine is running lean, if below 1.0 the engine is running rich. You have a lean condition, which could be as simple as a vacuum leak.

    Just get the factory unit and be done with it. Piersburg is supposed to be a supplier to Porsche, but the units I have seen in the aftermarket do no look the same.

    I have no idea where you subwoofer is, how about a photo?

    In relay panel #2, under the rear parcel trim panel, behind the rear seat backrest.

    As I mentioned earlier, we only use the factory pump. Your old cap sounds beat, the new cap is about right.

    Welcome to RennTech You are not the first, nor will you be the last to run into problems trying to mate unknown after market technology in the Porsche MOST and CAN Bus technologies. Even some "top of the line" audio systems have problems with this. MOST is fiber optics, and CAN Bus is a single twisted pair networking format. Good luck.

    Many OBD II scanners do not successfully read Porsche codes, particularly for something like the PDK. You need a Porsche specific tool (Durametric, PIWIS).

    Welcome to RennTech I think you will find that this device is no longer made. Try looking for a used one, or fabricate one yourself.

    Sometimes it is the simplest things. Glad you got it sorted, now go get a factory pump.........

    Chance would be a fine thing. $5-10K would be an excellent deal, the annual lease costs for a current PIWIS system is $20K per year...……..

    0.032 is more than a little lose for this bore size, the old rings are closer to correct. To make sure I understand where you are, you cannot get the piston into the bore with the new rings on it, correct? If so, what kind of ring compressor are you using? And where did you source the replacement rings from?

    Checking the coolant for combustion by products was a good idea, you have removed another possibility. Now, about that water pump...…...

    I called two wholesalers that handle Gates and aske them to look, one said metal, the other composite. I think the Gates is a 50/50 proposition.

    Welcome to RennTech What is the end gap of the ring in question when inserted alone into the cylinder bore at a depth of about 1 inch below the deck?

    It is not a matter of personal concerns, it is on the advice of legal counsel. What other website do or do not do does not concern me, but we cannot allow either this site, or me personally, to become the "deep pockets" in the legal equations resulting from actions beyond our control.

    See my response above.

    Let's start with the basics: Year and model of the car, and what code are you seeing?
  22. JFP in PA
    Touchy subject. The TPMS is a federally mandated safety system; altering it, or turning it off could result in the party that told you how to do it being held liable if you got into an accident afterwards.

    Try board sponsor Sunset Porsche Parts, they have an excellent online section for searching parts.

    You need to look behind the water pump at the engine case wall.
  25. JFP in PA
    I believe the Gates pump has a metal impeller: I am concerned that the pump was replaced because of overheating, not because the pump had failed or was making noise. The question is why was it overheating? At this juncture, if the car was in my shop, I would pull the water pump and look at both the impeller and the wall of the engine case. If the case is tore up, you are chasing your tail trying to get the system to work. As for the reviews of the pump, some "complain" the impeller is composite, others complain it is metal, so it sounds like they could go either way. In any case, we ONLY use the factory water pumps, which are all composite impellers, and work well, unlike several aftermarket brands we have looked at. Unfortunately, many aftermarket bits for Porsches are really junk; water pumps, surge tanks, and AOS units are great examples of what not to buy. We have seen several fail right out of the box. Yes, they are a few bucks cheaper, but after some people have gone through two or three units in quick succession, that few bucks looks like a really bad deal...…..
