  1. UPDATE. Problem solved by fitting another control/trigger unit and all seems good now.
  2. I have a 2001 Boxster S and has the airbag light on. Plug in Piwis and PST2 and same thing happens. I cannot erase the 5 faults even though showing not current. I decided to add a couple of faults by changing coding like belt buckle and seat belt. I re wrote the coding and now have 10 faults that I cannot erase. Returned the coding to original and still unable to clear the now 10 faults. I suspect airbag trigger ( control unit) codes originally were 3 power supply 195 unknown DTC 29 Ignition circuit side airbag driver 53 side airbag sensor driver 56 side airbag sensor passenger Anyone have any thoughts before going for the very expensive control unit???
  3. problem solved I think. I know many don't update their resolved issues so thought I would. It turned out to be pin 14 in the engine harness block connector wasn't making a good contact. Once sorted that all has been good. Thanks for the advice and help
  4. Hi. I have a 2004 996 Carrera that every few days throws the CEL then feels low on power and when plug in Piwis it comes up with fault code P1328 Inlet cam, bank 1 driver. I have swapped the valve solenoid from bank 1 to 2 in the hope the code would change to bank 2 but it didn't. Any ideas before I start getting too far into over next few days? Cheers guys.
  5. Mine was the solenoid for the valve lift system. The one nearest to middle on each bank. I found it by swapping left to right then waited for CEL to come on and hey presto the fault had swapped sides to cyl 5. Swapped for new and no problem since.
  6. only faults that I have seen are 000C FL SHOCK ABSORBER VALVE 000D FR SHOCK ABSORBER VALVE 000E RL SHOCK ABSOEBER VALVE 000F RR SHOCK ABSORBER VALVE Sometimes all at same time, sometimes just FL and sometimes both rear. Its so variable and sporadic.
  7. I have 2007 997.1 that has an intermittent PASM fault. Start car and drive sometimes few seconds ,sometimes an hour. PASM failure comes up and obviously goes into default mode. Plug in PIWIS and get fault varying from all four Shock absorbers (dampers) to sometimes both rears and sometimes Front Left. Faults are very inconsistent. have done the usual things of calibrate steering sensor,check coding of units etc,check connections. Feeling it is PASM control unit but customer says he had a unit plugged in and it was still the same. The actual values seem ok when driving with Piwis plugged and and watching them then one will drop out and as system goes to failure all current values read 0.00A
  8. I have 997.1 TT that keeps coming up with EGTS fault codes P0546 and P0549. The temperatures appear to be stuck on 1100 degrees C when enter through PIWIS tester. Have replace the EGTS sensors and still have the same problem and reading. Any thoughts? or does anyone have wiring diagram for the multi plug that connects to the block for sensors?
  9. Hi everyone. I have a Cayman S 2006 here and has a random misfire only from cold. With the Piwis it gives fault codes P0300,P0301 and P0303. I have changed all coils to updated version and spark plugs although all looked good. I changed the AOS as found small amounts of oil in the intake but still get same codes. Start from cold and after a minute or so misfires, CEL on and running rough. If I turn off and restart everything clears. sometimes it will come back on soon after but usually then its totally fine. Any ideas? Am going to play a little more with PIWIS but all activations etc seem normal but I only have a few minutes when first run engine everyday or I simply end up with good running engine and the fault codes above. The camshaft deviations and figures seem to be ok as I just checked them.
  10. final update thanks for your advice guys but it was a stuck injector on cylinder number 1. I removed them all and took them to injector specialist when put on test rig the injector for number 1 cylinder was like a hosepipe as soon as igniton switched on. the white/blue smoke was excess fuel.I replaced that one and ultrasonically cleaned other 5 and problem solved!!!
  11. will do that tomorrow but i only had that code once.cleared it and now even with rough running,misfire and sometimes thick white smoke then blue smoke it hasnt returned. I suspect the code was as result of bad running engine and not the cause. the sensor is only a year old and was genuine from dealer. If sensor disconnected surely it goes to set reading and therefore although may not be perfect it would run better? white smoke is indication of what usually in 911?
  12. JFP as i explained before,the ROW cars only have one sensor in middle of cat. Also if i disconnect it then it makes no difference to running Surely this should make the sensor reading go to lambda 1 safety mode? It made no difference
  13. update.... I had a friends car so plugged my 'bad' ECU into it and surpirsingly it worked perfectly so not the problem and the good running for 10 mins with a different ECU was coincidental. now at stage where i think injectors will be next course of action? also may borrow a gauge and check fuel pressure.i had a spare pressure regulator so already fitted that. thanks
