    Jeez I wonder if Bosch has serious quality control. I purchased two sensors 986.606.126.01 One is at 2.3 ohms One is OFL. The wrong ones I previous purchased 4.0-4.3 ohms. After installing the working Bosh 986.606.126.01 no check engine light and passed California Smog. Make sure you have the correct ones and that you didn't get a dead one from Bosch.

    Which one is the correct part number for the 1997 Boxster? I purchased LSH 25 986.606.126.01 0 258 003 806 12v 982

    O2 sensors are easy to test - see my earlier posts (in this thread). P1121 is a throttle position fault. Not really related unless the throttle is not closing when the DME tells it to. Try cleaning your electrical contacts on the throttle position sensor (electrical contact cleaner only) - and - clean your throttle body with spray throttle body cleaners. Clear the codes and see if they come back. I have a 1997 Boxster. On the Durametric software it says P1121 is throttle position, but else where its O2 sensor heating element after cat. I believe Durametric is wrong. Durametric fault code incorrect. http://986forum.com/forums/general-discussions/34974-durametric-fault-code-report-incorrect.html OBDII codes http://www.iwantaporsche.net/BoxsterCheckEngineLightCodes.htm P1117 Oxygen Sensor Heating 1 After Catalytic Converter - Below Lower Limit P1121 Oxygen Sensor Heating 2 After Catalytic Converter - Below Lower Limit The non working O2 sensor tested OFL which is why I had the P1121. The working old O2 sensor tested 1.8 ohms Both the New O2 sensor is tested 1.8 ohms. Now after replacing both the O2 sensor I get P1121 and P1117 which both the heater element is not detected or faulty. Similar situation with other forum members on the thread where replacing the O2 is causing more problems. Before I swapped O2 sensors I got P1121, I did not have P1117 at the time. I want to know how other members who had those problem and they solved it, if at all.

    "My dash vents (two on the corners and two the middles) don't seem to shut off when I deactivate the "vent" icon on the air con control console." If the vent icon and the up and down icons are off air will still come through. Try turning off the center icon and turn on only the up windsheild icon and see if air is still coming through?

    spark plug tube and the o-ring degrades with heat and time. Mine shrinked and leaked. They also got brittle when removing they shattered. Fairly inexpensive from the dealer

    That's some corrosive rain and sprinkler lol. Have you considered reupholster the seats and at the same time have colored stitching and different color leather or what ever material is offered?

    If I had to go through the hassle of engine replacement Id go with a larger motor. Not sure what the OP's options are in "Manila, philippines"

    How much performance would you get with that modification?

    From my experience with the window regulator changes on my boxster, the window can be adjusted backwards or forward. Check your window bracket positions on the regulator .

    The headlight switch contols both the driver and passenger side, so I doubt its that when only one light goes out. If the wires check out okay meaning not loose. Then its the ballast behind the headlight unit going bad. As it progessively get worse you will get more sudden shut offs until the unit stops working completely. A easy way to test it is, grab the good ballast on the driver side and switch it over to the passenger side and see if the problem goes with it. I have my money on a ballast going out if the wires checks out okay.

    Sorry to revive this 4 year old thread. Is there a definite solution? 1. Is the consensus to just wait it out? 2. Relay issue? Kind of strange if it was working before change and right after the relay goes. 3. Bosch has quality control issues ? or using a different heater circuit? I had only P1121 code, so I decided to replace both the rear O2 sensors NOT universal. I drove about 40 miles with several stops. While driving around 60mph and the cars all warmed up I get P1117 and P1121. Similar as what happened to you guys. I was under the impression that the Heater circuit comes on when the car is cold and not when its hot and running at high speed? Thanks
