    By hydro lock, the start motor can get the engine up to around 360° before the engine gets stuck by infiltrated liquid (depending the specific piston possition) Hydro lock can damage engine components as cracked liners, bent rods (when driving through deep puddles of water, a quantity can enter in to the engine via air filter) etc. Will occur occasionally during the RAC rally in the UK. This is a general description of a hydro lock. I hope it brings some clarity on the issue lock.

    I do not think that Porsche Germany will loose sleep over this issue (guess why i know that), the dealer must solve that problem in first place, therefore he is appointed. You have the right to change any dealership, or at worst write Porsche North America.

    The problem with cleaning is that a specific active product, which is responsible for the air mass measurement, is applied on the element by a "vaporization" process (hot film). Each contact with a cleaning product and/or swab would disappear a part of the active product, it may be that the CEL sometimes would disappear temporarily (is within the adaption range) but the air mass measurement will never be perfect, therefor a replacement is recommended by BOSCH/PORSCHE. I hope that the element operation is understandable.

    It will happen with all brand of street tyres and correct standard alignment, the explanation why,is already somewhere on the board, it has something to do with the unequal front left - right wheel rotation angle in curves, and pronounced with fully turned steering wheel. This of course is a brief and simple explanation.

    The correct interpretation of the noise and circumstances would make it easier. The wheel possition problem occurs especially by full turn at first start, in cold conditions. The sound is like scratching of cold hard rubber on a rough surface, sometimes the wheel jumps a little rather than rolling, perfectly visible for a helper standing next to the front wheels. It does not happen with warm tyres and hot outside temperatures. Other noises belong probably to other parts.

    Have you already checked the mountings of the engine compartment purge fan? It's just an idea.

    The accessory system is probably confused by a combination of circumstances, let ALL available KEYS reprogram with a PIWIS diagnostic/programming tool.

    Remove the air filter box, alternator and throttle body (make it easier and create more room). The oil filler pipe is bolted on the top of the engine block (2 bolts). Parts needed: 1 x O - ring and 1 x oil filler pipe. Success.

    The problem is that only months after, the damage become apparent like cylinder heats, water pump, etc. eaten away by chemical influences. Costs can be expensive in most cases.

    Unlike the 996/986, where the emergency cable is connected directly to the lock mechanism, 997/987 cable is connected (simply bound) to the solid plastic sheath(conducting) of the electric motor - cable unit, which is operated by the release button inside the car. If the emergency cable is pulled, the fracture risk of the sheath(conducting) is approx. 80%, then obviously a new unit must be placed. If you indicate as the door is open, why not plug power in to the cigarette lighter with a battery maintainer or something similar?

    COLETA 1) HC 20 - 100 ppm / CO 0,01 - 0,03 / CO² 15% - 16% / O² 0,1 2) Exhaust tip 3) Hot engine, idle + 3.000 RPM with slightly varying values 4) Abnormal values may indicate cat problems when used together with a digital temp. gauge and PIWIS in "ACTUAL VALUES" mode. The specified values refers always to stock engines, DME and cats, and may vary depending on the generation of the used DME and pollution standards EURONORM 3 - 4 - or 5. This simple verification process takes just 5 minutes longer than the usual procedure, it can be performed at the same time with the PIWIS and hot running engine, provides a quick and reliable diagnosis. Of course, knowledge and experience are necessary to diagnose, because it is not just to read date from a sheet. WVICARY Indeed, normally the engine should trow misfire codes on the respective cylinder bank in first place, but well, we were finally not there and can only assume.;) :cheers:

    MY 2005 (997) should have already PCM 2.1 IMHO.
  13. RFM
    Cleaning and lubrication is at best a temporary solution IMHO.

    wvicary, Faulty cats are more common over here, partial melted and broke as well, and have only two years warranty :angry: . In all cases of engine codes (PIWIS), misfires, etc. we did a supplementary quick cat test as following, four exhaust gas test HC - CO -CO² - O² on both banks, using the left - right difference values to detect anomaly's, followed by a cat temp test with a digital temp tester, the output side should be 50°C hotter than the input if the cat is still in good shape. Damage to the cat should be already, serious before a specific code appears.

    It is true that Porsche demands a vehicle readout, performed with a PIWIS and send on line, before it may be started with some work under warranty terms. If this is not possible due to circumstances may a problem arise, although soluble, they can claim the DME to read out much more in detail than a dealer can do with a PIWIS. Hope the DME is still stock in this case. Anyway it's not certain that the engine is lost, a failing fuel pump is also possible, think positive, the show is not over until the fat lady sings.;)

    If you disassembled the rear protection you will see more, could be a leak in the power steering tube.
  17. RFM
    Original Porsche coolant can be mixed, green (older) and pink newer). A mixture of several different brands and types may be problematic and not worth the risk.

    Under normal circumstances, the belt can stay 90.000 Km or 5 years on the engine. The following points should be observed: wear and/or damage to the grooved pulleys, condition of the rollers - smoothly and without any play, operation of the automatic tension system, wear of excessive play on water pump, power steering pump, AC compressor, etc., operation of the AC pump + electromagnetic clutch, freewheel pulley alternator if installed, proper belt install - alignment. Given the respectable number of miles on the car, i do expect some wear.

    Unlikely that an oil change will help, although i think that in some cases when no error codes are present, which indicates an electrical/mechanical related issue, the problem can caused by a specific type of contamination inside the Tiptronic. There is always a new valve block, filter and oil change procedure performed according to the manufacturer's instructions. I do not know of anyone has experimented with a special cleaning action ATF oil additive.

    The cable adjustment mechanism is located under the shifter, if you are not familiar with the system, lack on tools (adjustment tool), is it cheaper to have it done at the end, it takes only 15 minutes for someone with knowledge.
  21. RFM
    +1, that's exactly what i think also.

    Happy New Year to all members and staff of this site. RFM

    Read Loren's post again carefully, there is no room to take risk on safety items.
  24. RFM
    If you have completely finish the list inclusive PIWIS diagnostic/program tool, with no avail, then the problem must be inside the unit.

    Allu. pipes are replacement parts on Cayenne V8 up to MY 2006 to the well known crack problem, for some obscure reason they made the cooling pipes back in plastic, smaller and different in design by the direct injection system lay out inside the V, at the height of the cylinder heads.
