Let's close this and roll any additional discussion into the thread aready started on this... Porsche Takeover

If they are not leaking into the spark plug channel or to the outside of the engine - then don't worry about them as they are likely the newer design. In the Porsche engine design the spark plugs sit in the middle of the heads between the two camshafts - so the spark plug is kept seperate from the oil by the tubes. Besides you need to be able to access the spark plugs without removing the heads. Older VW and Porsche designs were similar except they ran the the lifter pushrods through oil tubes. (and they leaked too - LOL)

M573 is Air Conditioning. Does your car have AC?

Have a look in your Owners Manual - it lists with and without filter. 7.8 liters but always double check with the display in the cluster.

:welcome: Do a search here as several owners have had similar problems and most are fixed for little or no money. Start by checking that the drains (under the top) are clear - you can test them with a pitcher of water. Many folks here with good advice. BTW... if they replaced the control unit under the drivers seat that would be the alarm/central locking control unit not the Engine Control Unit.

:thumbup:

Yes, they are rear belts for a coupe.

For C4 it is 25 Nm (19 ftlb.) plus 120 degrees tightening angle. Yes, a 996TT is different (different engine and flywheel - and 996 is 8 flywheel bolts and 996TT is 9 flywheel bolts).

Hmm... do you know which option code you have and which one you need?

On a 987-2 Boxster?

Will this work for a MY04 Cayenne as well? Yes, it should.

Stone Guard - do you need the right side or left side or both?

Ok, check where the headlight plugs into the socket inside the front fender. Look for a damaged connector, damaged connector pin, or pin that has been pushed out of the holding socket.

It is not a performance issue - if the octane level is too low you will get pre-ignition and detonation -- and possibly damage (a very expensive) engine.

Ok, no Porsche content here so this topic is now closed.

You will need a PIWIS tester and someone that knows how to use it (sic).

Other than a dirty fuel filter (from picking up the debris in the bottom of the tank) - I think you will need to look for fault codes or pending faults with a diagnostic tool.

You can try the reset procedure which involves reversing the battery for a few seconds. You should also try a new battery - if that fails then you can see if a shop or dealer can reprogram the key for you. Worst case you will need a new key.

Turn on your emergency flashers and walk around the car and make sure they are all working.

P0040 Oxygen sensor ahead of catalytic converter – signal implausible (only Turbo) Possible fault cause - Oxygen sensors ahead of catalytic converter exchanged - Line polarity reversal in wiring harness - Simultaneous occurrence of leaking fuel injector on the one bank and leaking intake distributor on the other bank Diagnosis detects oxygen sensor - regulators running contrary to the adaptation limitation. - For example: The regulator for bank 1 detects an excessively rich mixture and wants to make it leaner. At the same time, the regulator on bank 2 detects an excessively lean mixture and wants to make it richer. If the oxygen sensors or their signal wires have been exchanged, the detected bank 1 continues to make the mixture richer and bank 2 continues to make the mixture leaner. Only when both oxygen sensors remain on the opposing stops for a certain period of time will this fault be recorded. 1. Check if the oxygen sensors were exchanged due to incorrect installation of or tampering with the wiring harness. 2. Disconnect oxygen sensor plug connection ahead of catalytic converter, bank 1 - Visual inspection - Remove control module connector B Check following wiring for continuity: - Oxygen sensor connector ahead of catalytic converter pin 1 and DME control module connector B pin 15 - Oxygen sensor connector ahead of catalytic converter pin 5 and DME control module connector B pin 9 - Oxygen sensor connector ahead of catalytic converter pin 2 and DME control module connector B pin 2 - Oxygen sensor connector ahead of catalytic converter pin 6 and DME control module connector B pin 5 All should be <2 ohms. 3. Disconnect oxygen sensor plug connection ahead of catalytic converter, bank 2 - Visual inspection Check following wiring for continuity: - Oxygen sensor connector ahead of catalytic converter pin 1 and DME control module connector B pin 16 - Oxygen sensor connector ahead of catalytic converter pin 5 and DME control module connector B pin 10 - Oxygen sensor connector ahead of catalytic converter pin 2 and DME control module connector B pin 6 - Oxygen sensor connector ahead of catalytic converter pin 6 and DME control module connector B pin 24 All should be <2 ohms. 4. After reading out the oxygen sensor values, search for a leaking fuel injector on the bank with the lean threshold and search for false air on the bank with the rich threshold. Since you only have misfires on bank 2 (cyl 4, 5, 6) it would be interesting to see the O2 sensor readings compares between bank 1 and bank 2.

They should not have.

Usually a bad cap sweats or leaks. Look for residue on the top of the coolant tank.

:welcome: That rear offset is for a widebody car like C4S or Turbo. A narrow body car C2 and C4 needs 63-65 mm rear offset for 10" wheels.

These #'s are stamped on the belt clips. I mean the car type they came from (coupe, cab Targa). Coupe and Targa are interchangeable but not Cab.

And the MY09 Turbo S has yet a different shaft 955.421.020.24
