I'm new to 911/996 world....this is a great site and learning so much just reading random post.

Recently purchased a 2003 996 Targa and now unable to open the rear hatch either via remote or the direct button on the door sill.

I tried opening/closing the roof multiple times as realize the roof must be in full close position.

During the PPI, there were a few roof error codes in the system, but the battery was very low so the errors were thought to be connected to the battery.

Read somewhere that disconnecting the battery might clear error codes, but even if that works guess it's just a short term solution.

Seems that error is related to a sensor somewhere or an interlock issue. I really enjoy the Targa roof but hoping this isn't the start of a messy (expensive) situation.

Thanks to all who might be able to share some advise!

Thank you so much for the quick reply!

I disconnected the baterry to clear the interlock codes......good news.....hatch worked so doesn't seem to be a mechanical issue.

Now the bad news.....after I gently closed the hatch and heard the solenoid close it the rest of the way for a flush fit, I tried to open the hatch again and no luck.

Seems like some kind of a sensor issue where hatch doesn't know that it's fully closed.

I don't plan to use the hatch often so not a huge deal, but sure would be nice to be able to open it when needed.

I think you missed my point about the battery. It is known that a weak battery will cause all kinds of electrical "glitches" in these cars.

I suggest you take your battery out and have ti both load tested and specific gravity tested on each cell. If your battery is 4 years old or older - replace it. You will save yourself lots of headaches.

Loren, thank you again for the quick reply. Really apprecaite it!

Good to know about the 'weak' battery issue...I'll definately keep that in mind for the future.

In this particular case, I actually already changed out to a new Interstate battery.

Don't have a juice problem in this case, seems like some type of sensor/interlock issue but don't know how to better diagnose that

      If you have a 996 Targa you'll know that the little rubber piece that covers the rear glass' latch tends to degrade and fall apart. I designed a replacement piece that you can 3D print. Just make sure that you use PETG or ABS plastic so it doesn't melt when your car is sitting out in the sun. I'll probably get some filler primer and some matte black paint to make it match the rest of the trim, but I think it turned out pretty well.

      I don't know how much a genuine replacement costs, but it was a fun little exercise for me.

      Hi all, 
      First of all I apologize if I do anything wrong since I only just created this account in order to ask this community a question. 
      We own a Porsche 996 Targa 2002 and as we all know the 996 is prone to engine problems such as IMS and oil and coolant mixture.
      Today when I was checking if the engine still had enough oil and coolant and decided they needed a fillup I saw something that I did not really like. 
      I've uploaded two pictures one of how the coolant looks and another picture of where you add the oil.
      Is the yellowish stuff you see ok or is this the first sign of the oil and coolant mixture? 
      The car seems to run fine and never had any problems with engine temperature, hope you guys can help me out on this one! 
      With kind regards,
      A somewhat nervous 996 owner.

      New on this site.  Short intro - bought a beat up 993 Targa 3 years ago whilst living in Dubai.  Spent some money on it including a bare metal respray then Company transferred me to Singapore but couldn't take the car with me so exported it back to the UK as I couldn't sell it.  
      Car has failed its MOT on emmissions - no surprise but trying to find out exactly what it is fitted with.  The car went straight from the factory to the Middle East and has the following options:-
      Rest of the world car
      M6422-63T Engine
      C32 - Arab states
      M150 - leaded
      Can anybody shed any light on what the above codes mean in terms of a catalytic convertor, lambda sensing etc, especially C32 and M150 codes.
      Thinking to fit a sports cat to it.
      Some pics added for interest.

      I've searched the forums, and I haven't found a similar issue...
      I have a 2004 Targa and the windows have been working great up until the last couple of weeks.  Now when I have the passenger window down and I press the switch for it to go back up, it'll get about half way up, pause, and then put itself back down.  After a couple of tries I can manage to get it to go all the way back up by holding the switch down.  I've tried resetting the limits, but that didn't help.  The driver's side window works great.
      Any ideas?

      I've searched the forum and couldn't find an answer and am posting here for your help.  Let me know if this isn't the right place for this question.
      I'm  searching for my first 911 and am confused about the headlights.  On one 911 targa (2002) the options sticker does not list Litronic headlights but the owner and ppi shop said it does.  Another 2002 targa lists the option on the sticker.
      Do some 2002s have Litronic/bi-xenon headlights as standard equipment?
