Targa / Catalytic Convertor Help Needed

Recommended Posts

Howdie

 

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.

Welcome to RennTech :welcome:

 

Biggest issues I see is the "M150"  and "C32" codes, which means the car is designed for use with leaded fuels in the Gulf states (which had no emissions requirements).  This option meant that the cat canister's under the cars were empty (no catalytic cores), the cars had no 02 sensor system, and use a unique OBD system to control fuel trims due the lack of O2 sensors.  The UK has been mandatory lead free gas since 2000, and I understand uses the same OBD II "I/M Readiness" test that North America uses, which requires both cats and o2 sensors (although the RoW cars with cats of that vintage only had two O2 sensors rather than the more common four in NA).

 

I would think it is going to take quite a bit of work to get the car accepted by the UK MOT system.  The DME will need to be reflashed to use O2 sensors (which would need to be installed) as well as unleaded fuel, and the car will need real cats, all of which is going to be expensive.

Thanks JFP. Will start with adding a cat and see where that takes me.

 

If anyone has any info / pics of the CO2 pot, it would be appreciated.

      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.

      Just cleared OBD for O2 sensors, replaced all four.  Now no error codes, however, loud intermittent/sporadic clunk sound and seems to come from exhaust manifold or cat.  Also, no improvement on engine performance.  Still idles rough when cold.

      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.

      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?

      Hi,
       
      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?
      Regards,
      Mike
