DBJoe996 replied to Andrew911's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I would say the simple answer to your question is no. I think you might have to backtrack and make sure all of the wiring is connected right, including the DME. Might help to unplug the DME connectors and plug them back in again. Do the power functions of the seats work? After that, do a complete system reset by removing the negative battery lead, wait 15 minutes, reconnect and see how things work. If after that the problem is not resolved, you might have to start checking fuses and relays.
DBJoe996 replied to Ric4s's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)You also need to check the vacuum lines. See this forum thread https://www.6speedonline.com/forums/996/208326-code-p1516-intake-manifold-switchover.html
DBJoe996 replied to Ric4s's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Also, if you have a MAF sensor, clean it with MAF sensor cleaner. It has been known to cause ABS/PSM faults and rough idle.
DBJoe996 replied to herm5000's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Hate to say it but it seems something is wrong with the HVAC control panel. If I push the snowflake button, that engages the AC compressor to pump freon through the system, and I can manually put the fan speed anywhere from low to high, and direct the air manually to defrost vents, dashboard vents and floor vents, any or all of these. To put the system in maximum cooling mode, hit the snowflake, put the temp control on LO, push the recirc button, push the dashboard vents button, and manually put the fan on HI. As far as I know, when in this mode (or for that matter any other mode other than AUTO), the fan speed is independent of the AC mode and operates anywhere from LO to HI. So it comes back down to...why when you engage the AC does the fan blower not manually operate from LO to HI? It should. So I think something is wrong with your HVAC control panel. Another question, what does your voltage read when you engage the AC? Does it drop a lot or stay fairly steady at around 13V?
DBJoe996 replied to OneDayIsHere's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Record your mileage before sending it in for repair. Mileage is stored in the instrument cluster. Good luck on the repair.
DBJoe996 replied to herm5000's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Stupid question - are you running it in the Auto mode or manual mode? In other words, what happens if you switch the AC on and use the FAN button to increase the airflow?
Actually I don't know where #35 can be seen or reached. Sorry not much help there. May have to trace the steering shaft up under the dash and go from there. Someone else was having some problems with new Conti tires. Seems molding lubricant in tire manufacturing was making the tires feel slippery. Have you considered a Hunter Road Force balance? Could be something going on with the tires and wheel combinations. Are you running wheel spacers?
Seems you have replaced just about every part that would play a role in this, and had things checked and an alignment done. Not that it is common, but I wonder if the steering shaft has some play in it, i.e., the spline shaft and the universal joints. Might be worth it to check the bolts that hold the steering shaft #10 and #35 here - http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=996-99-05&section=403-05
DBJoe996 replied to creekman's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Bleeding the clutch system might help, but if the deterioration has been over some time and simply now is worse, my guess would be the clutch master cylinder seals and not the slave cylinder.
DBJoe996 replied to mjbiegs's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)There is a rubber stop Part #9 here http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=996-99-05&section=801-40
DBJoe996 replied to Andrew911's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Check the obvious to begin with...fuses and relays. With a multimeter, see if the latch actuator is getting power when the button is pushed. Could be the button, but more likely the latch actuator. You can find the drive motors and microswitch (which usually is the culprit) here: http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=996-99-05&section=811-01
DBJoe996 replied to laalves's topic in 996 TT, 996 TT S, 996 GT2Maybe this will help, and a 2 ton bearing puller https://rennlist.com/forums/964-forum/663697-c4-front-inner-cv-boot-or-joint-repair-2.html
DBJoe996 replied to greenrs's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I would pull both of the overhead infrared sensors and check them out. Could be one of them is shorted out or bad. Check the wiring as well. See if there is a short to ground.
