    I haven't seen PIWIS used on that control box - but it is the controller network. But I do not know what faults it stores. The front controller problems have been sporadic and intermittent but changing the front control box has solved the problem on several cars that I know of.

    In the 997 the rear lights are controlled through a rear light control box. Has your dealer tried changing that out? I know that they have had problems with the front control box but this is the first I've heard with the rear control.

    AX has recently been replaced by CX and was for MY05 - but now it is also for MY04. It is still an X51 engine.

    If you are going to change the fluid I would drop the pan and change the filter and gasket too. Didn't you do this last year? How many miles?

    Exchange engine - 996.100.995.AX (replaces 996.100.996.14/20) New engine - 996.100.996.27

    Almost sounds like an intermittent wire or connection since sometimes it works. I wonder if the pedal sensor is bad? The Durametric Software can read and reset codes for ABS, PSM, AC/Heating, Airbags, Tiptronic, Seat memory, etc. It can read but not reset alarm codes. I don't know of any other tool that can do that besides a used PST2 ($2000-$4000 on eBay) or a PIWIS $18,000 at your dealer.

    A "re-learning" is needed whenever changing out the MAF and a few other critical DME controlled parts. This is normal and usually only takes a few miles and a short time. That is why Porsche techs test drive the car after a replacement. I think it takes a little longer if the car is a TIp as it has to re-learn it's mapping also.

    You can even drive up on 3 2x10 boards (that is what I use) - 3 inches is about all you need.

    For MY99 Carrera - Tip P0740 Fault, torque converter clutch - present Potential causes: ATF level not OK - ATF supply Torque converter clutch worn. - Torque converter Mechanical damage to pressure regulator 4. - Pressure regulator 4 (hydraulic) Open circuit, short circuit to ground, short circuit - Electrical triggering to pressure regulator 4 to B+. - Hydraulic control unit Sticking valves. I would definitely start with fluid level.

    I would start looking at lines and the change over valves for leaks and blockages. 1 - Secondary air injection pump 2 - Air change-over valve 3 - Electric change-over valve 4 - Non-return valve 5 - To the cylinder heads 6 - Vacuum reservoir 7 - To the intake air system

    Sunset Imports or Carnewal.com. Get the kit that is spacers and 5 mm longer bolts (000.044.500.09).

    You need to have someone check for alarm faults with a PST2 (or PIWIS) or Durametric Software. I think there is a fault code somewhere there...

    P0410 Secondary Air Injection System - Signal Implausible (Cylinders 1 - 3) P1411 Secondary Air Injection System - Signal Implausible (Cylinders 4 - 6) Potential causes: Secondary air injection pump is not triggered. - Wiring harness or fuse Secondary air injection pump does not work. - Relay Air supply lines restricted. - DME control module Electric change-over valve does not work. - Air supply lines Air change-over valve does not work. - Secondary air injection pump Vacuum system leaks. - Electric change-over valve - Air change-over valve Did you or someone disconnect the secondary air pump? I would start by checking for the noise when you start the car cold - the secondary air pump should run at least 30 sec (or more). Sounds like a small vacuum cleaner to me. If you don't hear the noise then check the electrical connections and fuse (40A fuse on the relay board next to the DME), and the relay (position 10 on the same board).

    Model year please? Did you replace your 3rd brake light with an aftermarket clear LED panel?
  17. Loren
    The Durametric mateched the PST2 in my tests. Was this the problem you had before replacing the throttle body? Did you do it or did a shop use the old throttle sensor on the new throttle body?
  18. Loren
    Which parts exactly - reassembly is just a reverse of the disassembly. Ducts go on first then the front bumper cover etc., etc.
  19. Loren
    Well, I would check your steering pump fluid first. If that is okay then try jacking the front of the car up and rotating the wheel(s) while listening for noises. You can also check the lateral free play to see if the wheel has any.

    Check for a P0102 fault. P0102 is the same error you will get if the MAF is unplugged. This can also cause ABS and TC/PSM lights to come on as the DME is not sensing the TC/PSM data and combining it with the throttle position and mass air flow readings. If you are in the US then Autozone (and some other parts stores) will read your codes for free.
  22. Loren
    If the wire is all brown then that is a ground wire. The radio alarm wire is brown with a blue stripe.

    You need the PST2 to check for fault codes and to verify that the throttle is reading 80% at full throttle. The Durametric software can give you those same readings.
