  1. Answer from 9ff in Germany:

    We know this kind of starting problems. Most times the reason is a broken fuel pressure hold valve. Its position is inside of the fuel tank in the pressure line 10 cm away from the fuel pump. The car needs it to hold the fuel pressure in the lines between engine and pump. If it is broken the fuel in the lines on top of the engine becomes hot and goes from liquid to gas. Then engine can not start any more before it is cooled down.

    Check the valve and let me know.

  2. I checked the stroke for the wastegatevalves today, on the right side everything was ok, but for the left side I could notice a leakage from the vacuum box. The car was running ok before without any strange noticed, correct boost pressure and so.

    Also in the OBD reader there was no fault

    Why didn't I see any strange then driving the car ? :unsure:

  3. The instruction text is copied from a workshopmanual (I will not print the manufactor).I think the translation had been done from German into english.

    "Installation position of the pedals in accordance with the series condition" mean??

    -I think they mean that You have to check the installation of the pedals, (not correct installed as it should be).

    I don't know if it's possible to You any other type of oil than Pentosin CHF 11 S.

    To bleed the system,see attachment

    You have got mail

  4. The clutch actuation occurs in the 1st 10% of the pedal travel. In other words, when the pedal is almost all the way away from the floor. It is really annoying as it makes it difficult to drive smoothly. There must be a way to adjust it so that the actuation occurs closer to the middle of the pedal throw. I have searched found nothing.

    Thanks for any help!

    Procedure to check clutch pedal:

    Clutch: checking the play and pedal end position

    - Checking clutch free play

    - Checking the pedal end position (pedal return/return force)

    - Checking clutch free play

    The clutch master cylinder has an inner stop. The push rod and the clutch pedal are always pressed against this

    stop by the boost spring. Due to the automatic hydraulic adjustment of the clutch, it is not possible to

    determine the clutch play by checking at the clutch pedal.

    top of page

    Checking the pedal end position (pedal return/return force)

    - Check that the pedal is in end position by pulling at the pedal (without the use of force) towards the

    driver's seat.

    Note

    · The pedal must not give way during the process.

    · If it gives way, the fault is in the boost spring or in the pedals.

    The clutch push rod and the boost spring are not adjustable. The boost spring has 2 functions, namely to

    provide pedal force assistance and to return the pedal. The following are some of the points which are

    requirements for perfect clutch operation:

    · Correct bleeding of the clutch hydraulics.

    · No leaks in the hydraulic system.

    · Pedal return to the starting position.

    · Installation position of the pedals in accordance with the series condition.

  5. Where exactly are the dump valve placed?(pic)

    I was with Jonas this weekend and we could read out a fault number P1250. this code says:

    - Boost Pressure Control Deviation - Above Limit

    and the one of the faults could be:

    Adjust by pass flaps, but what is the "by pass flaps", is it the same as dumpvalve?

    It's also a warning for a bad brake pad, could that course the low boost preassure?

    Bad brakes---> Low boost preassure????

  6. What's the CAN-bus ?

    I can guess it's a sort of communication bus, but what kind of signal, information are send in the bus ?

    Is it any plug for connect an external PC such as for the OBD or is it the same plug ?

    Is it necessary to have any special modem for reading the values to an external PC (if possible)?

  7. I got 9ff wheels with center lock on my car, the only thing You need to change is to take away the "five bolts" thats are inside the rim, on my car it's also spacers that are fitted with this bolts and replace this bolts with original wheel bolts. You also need to change the center bolt to a original center nut (for wheel bearing). The center bolt is only locked with a spring and a washer.

    The job is done less than 30 minutes.

  8. The oil is dark green. It's also very aggressive to rubber material, so be careful then/if you fill more oil. (Special the AC hoses).

    You should have a cap (d=7mm) close to the filler cap, check so that one is in the right place and not gone.

    It's also very important that you use Pentosin cfh11s oil.

    BMW use also pentosin oil if it's difficult to get in your town. I bought a bottle from the BMW dealer in my town and the bottle have also the Porsche number on.

  9. hehe  :)

    You can go to a Porsche facility and ask them to update your PCM to a newer (software in PCM), in that version Sweden is "longer"  :)

    Update is free but you probbably have to buy the CDs and thats

    2600 SEK

    I did that last friday, but .... Sweden is not longer after the update.

    Anyone that knows the possibility to use from another car ?

    For example it's possible to use OPEL cd's in PCM1, I have done that in my 99-c2 and thats simple, it's only to take the database from OPEL cd and put that into the Porsche nav cd. and then it covers all of Sweden

  10. Anyone that have data for the DME (7.8) set points, such as the attachment (valid for C2-99).

    I got problem with the codes P0172 and P0175 (O2 sensing below linit) and like to check with the obd reader what all values should be.

    The problem have comes up 2 times (after reset) and the car ( 996 TT-03) have been driven for about 60 km every time.

    I have checked the system for leakage and (I hope the problem was ) the air inlet tube was a little bit out of position and also 1 screw was loose for the MAF sensor.

    I also like to know where the canister vacum hoses/pipe is possible to find (picture)
