A parking attendent let my 2000 Boxter's battery die. After the battery was recharged I notced the radio was off. I tried to turn it on...nadda. I can't even get to a lost code request as the radio will not even power on, at all...period. Is this something anyone else has experienced? There is nothing I could find in the manual about this issue. Suggestions?

Loren,

I'm really sorry but I just don't see the answer to the question I'm asking in the Q&A page that you provided. I have checked the fuses and they all test fine and don't look to be blown. My uncle suggested that there maybe an internal fuse to the radio or that I need to disconect the battery again. I would just take it to the dealership but I honestly don't have the money to do so. If there is something I can do to fix it I will, but otherwise I'm out radio traffic reports and tunes without some porsche person help. I've never asked a question on here any maybe you think I'm a total blonde idoit...I'm not denying it...I'm just looking for help. :(

If the radio will not come on you should check the fuse panel near the left footwell - check fuse D8.

As I recall there is also a fuse on the back of the radio - but the radio will need to be removed to check this.

If you do not feel comfortable checking these then I suggest a good Porsche independent shop.

One other thing you can try is to disconnect the battery, touch the disconnected negative lead to the positive post of the battery. Sometimes these radios are known to "lock up" this usally due to voltage storage in the trisistors of radio and by doing the battery leads this voltage can be eliminated and the radio will work. It is still possible that the fuse is blown in back of radio. Just a side note that using a high amperage battery charger over 50 amps can cause damage to many control units in the Porsche. This battery procedure should be done when any odd occurances are happening with any elctronics in the car. Its amazing how many things this simple thing has fixed. svansyoc

the part number for 08 turbo front rotors are left/ 955-351-401-51 and right 955-351-402-51. These are 18 in dia. rotors however, what are the part numbers of your calipers. also this conversion to the larger brakes will require larger wheels to accomodate the rotors.

The engine failures were primarly due to intermediate shaft breakage, somewhere in mid 2005 the 987 had the larger shaft installed at the factory,at one point in time the reman engines from pcna were updated with the new shaft as well. Some people therorize that there is corrilation between engine revs and shaft breakage(although I know for a fact that it is not 100%). When buing a Porsche sports car I recomend going to shop that has the capability of reading the rpm/rev counts stored in the dme control unit. Basicly it can be in two diffeerent formats, earlier cars used an upper and lower count and newer vehicles had 6 or more ranges, each range means ignition counts after a specific rpm. The higher the range and higher the count the more the vehicle ran at higher rpms. (note the range is specific to different engines) any ignition counts in the upper ranges means possible engine damaging rpms have been met, so note the counts in the last two ranges in later vehicles, "o" is a great number. Also note that these counts follow the control unit and not the engine, if an engine has been replaced, the same counts will be stored.

I'm seriously contemplating buying a used 997 around the middle of next year. Yesterday, I stopped by a local and reputable independent Porsche shop of long standing and asked one of the shop's owners if he services 996's and 997's. He said yes, "up to a point" then warned me to get a thorough inspection and title check on any prospective purchase, because those models had engines "blow up" from what he felt was an internal defect. He also advised me to check the internet regarding this matter, and I was disheartened--devastated really, that there are indeed reports of such catastrophic engine failures.

My question is, do these failures involve mostly 996's and are they related to the RMS problems? Also, are there any steps beyond a comprehensive inspection, that can be taken to minimize the chances of one of these failures occuring?

Since I'm brand new to this forum and am not (yet) even a Porsche owner, I'll accept links to other topics within this forum that may answer my questions.

Thanks in advance.

I recomend you have a dealer do this update, when you recieve the update there will be a warning inside the kit to have an authorized dealer install it. I have done these updates and have had trouble sometimes, some of the pcm units have to be updated to a later version first, even when going in correct order, all appears to be running correctly and at the end it will not be able to read the disc or other issues, this has been more of a problem with the cayenne but have heard of issues with sports cars as well. If you have the latest pcm software this is an easier update.

I just found this forum & it appears to have lots of good and useful information. I have an 06 997 C4S Cab and an 83 SC Targa and love them both. I've owned the SC for many years and have done most of the repairs / maintenance myself (brakes, alternator, A/C compressor, cam tensioner update, etc). So far, I've had no issues or maintenance items with my 997 but it is about due for an oil change -- I plan put the tips listed to good use!

I just received a mailer from my local dealer announcing the latest navigation system update (#997 044 901 51) for $299 plus installation.

Questions for the forum:

Is there an alternate source for the DVD at a lower price?

Is this update a DIY project for a mechanically savvy but electrically challenged person like myself?

Thanks in advance.

Just a little side note on oil seperators, there should be a very slight negative pressure in the cranckase on a normally asperated engine while idling. The quick test if the oil cap is opened the vehicle should not die emediately or sound as if it has extreme gasping noise, there are gauges to measure this pressure, but a trick that we used in the shop is to use a latex exam glove with a rubber band around the fill tube, it should pull in when started showing slight negative pressure, if it balloons outward the seperator is bad, or if the extreme gasping noise is heard when opening (sometimes it can be even hard to get the fill cap off when this occuring) .

Remove the oil filler cap with the car running. Then cover the opening with the palm of your hand to check for suction. You shouldn't have any.

Many thanks, started her up and there is certainly suction there so that would explain the diagnosis.

Thank you for the warning on O2 sensors as well - will get it booked in ASAP for the work.....

You are right to believe that both the accellerator and electronic throttle valve both failed at once, most likely if codes are erased all codes will return right away. I have had one customers car (also a boxster S) that had similar codes, sadly it required a dme control unit to repair.
