  1.  

     

    Oil and filter change on a 996/986 is easy.  The drain plug is staring you in the face.  It is even more easy on a 996.  If a 996 is not lowered I can get to the plug without a jack.  On the mid-engine Boxster we have to jack up the left side a bit to slide under car because the engine is 180 degrees reversed. 

     

    Sorry, I should have mentioned that I have an '02 996TT and things look a little different than in the photos and the DIY drawings....neither seem to acknowledge a 996 Turbo. While it is still a 3.6L boxer, it is a different motor and I don't want to forget something important.

    First, the oil filter is inside the engine bay and not underneath like the 996..... I assume I want to take that off LAST (after gravity drains most of the oil out of the engine), unless I want a couple of ounces of oil all over the engine compartment?

    Also, should I be looking for a second drain plug underneath, like the oil resevoir and oil cooler radiator on the 930 Turbo that held most of the oil outboard the motor? Or is it now just one plug and gravity takes it all out at once?

    Thanks in advance for your help.

    You are looking at the wrong DIY. The TT/GT2/GT3 Oil Change DIY is here.

    I'll move this post to the TT forum so there will be less confusion.

  2. Did they swap out the oxygen sensor relay (position 2 - relay carrier next to DME)?

    and check or replace the oxygen sensor jumpers at relay position 6?

    If so, then there is nothing left except the DME.

    BTW... I show a retail price of $1878.09 for the DME (996 618 601 04). Maybe an hour labor to transfer the mileage/programming.

  3. Can you ask them for the fault codes? Better yet a history of the codes (they have these in the database). With a code histroy you might see a pattern.

    There are a number of Pcodes that point to a problem in the DME. Without the codes everyone is shooting in the dark.

  4. What were the fault codes?

    BTW... Back when my car was in warranty I had my DME cable connection come loose and my car behaved very erratically. The dealer replaced the MAF and then thought it was the O2 sensors and then when they finally went to replace the DME they found the cable was so loose it fell out. Once they put it back in (and tie-wrapped it) the car ran fine. Might be worth a look...

  5. I have never seen a MY99 with TC that did not have LSD (not to say it isn't possible). Check you option codes for M220 or M224. If you don't have the codes you can get a certificate of authenticity from PCNA that will show all of your cars' original options.

    The LSD on a MY99 is only 40%. From the tech manual:

    To get the engine’s power safely to the road in a standing start, slip is limited to 40 percent. Once under power, the slip factor changes to 60 percent because the engine no longer is operating at its maximum torque and also because this configuration helps minimize oversteer under load changes through a turn.
  6. I'm looking at the schematic (MY04 GT3) and I don't see anything different (power wise) than they have done in the past. A4 (red/black wire) should go to Fuse D8 (unswitched power) which is radio only.

    The Traffic Pro should have a switched power on A7 - you can get that from the phone prep connector (green/black wire as I recall).

    If the radio/Traffic Pro is on when the ignition is turned off then it should come on when the ignition is on again. Also, with the ignition off you should be able to press the on button on the radio/Traffic Pro and it should play for 1 hour (or until turned off).

    Something is definitely wrong with the wiring if the heater doesn't come on until you turn the radio on - they should be seperate circuits.

    BTW... where are you located?
