  1. Guys SOLVED! Actuator Valve 99710530100 Was the problem! It took me about 2.5hrs to take the rear fender off, heat shield and rear silence, exchange of the valve and then remake the car. Turned the key and zoom zoom it was perfected! If people would like help then this is more the likely their problem. It cost around 105 euro for the part and it cost me much more in problem! Thank you all for help especial Ahsai as it was that which helped above. Kiitos Björn (Nalle)
  2. Also, when running is rough I turn off and on and all better until I hit over 3.5 to 4k revs. Also it seems the rev dip and then there is a click and it returns to ok again.
  3. Hey Guys, New code today, P1090, and the idle is getting worse. Would it be helpful to post a video of the symptom. Reading this leads me to maybe three things, what do you think? a) Throttle Body or Sensor not good b) Lift solenoid problem c) Sticking lifter I have cleaned Throttle body, changed MAF so I am just not sure now. Bjorn
  4. Yes it is possible for me to do that and freeze frame as well. I will observe, when I did look at this before, it was one o2 sensor that was very up and down and performing like the other. Bjorn
  5. Kiitos Hyvää Ricky The reason for o2 sensor thinking was that it occurred when it was wet, and maybe symptom of short. I am not sure how to get to the VC solenoid, is there a rubber seal that connection with the Cam Cover? I know where the cam covers are either side, I can see the coil packs mounted to them. For the purpose of investigation, the general driving symptoms of the car are revs dipping when the engine revs of 3.5k and sometimes the revs drop to 500 and the engine is struggle. PIWIS data is just the random misfire on the 4,5 and 6 cylinder, nothing pending or rec
  6. Hei Ashai, No, it does not only correlate to the rain anymore, it is just when it started. I checked for the vacuum on the oil inlet, there is a lot suction on the pipe. I will get you the reading on the trim later, the 23% was on the short term, and it was on the same bank as the cylinders 4, 5 and 6, which diagnostically led me to think of the o2 sensors. Kitos Bjorn
  7. P0300, P0304, P0305, P0306 This is it! Which I understand is Random misfire, misfire cylinder 4, 5 and 6 My understanding is that a faulty o2 sensor can cause an misfire due to the mix (I think this is how you say it) is adjusted by the data provided by the o2 sensor which can cause failure of ignition for the reason of oxygen imbalance. Or am I misunderstood. Björn
  8. Apologies Yes new coils and plugs, I would assume the obvious. I was thinking to get a smoke test maybe, had new filters. CEL is on, but random misfires on bank 4, 5 and 6 is the only codes, which led me to think it is the o2 sensor on that side. At high revs it is fine, ran a fuel detergent for injectors and also cleaned throttle bodies etc. Had service done not long ago, new filters etc and oil change as well. Thank you
  9. Ok, So since it rained heavy, my car has started to idle rough and seems to dip revs to say 300 and then go back to good resting idle. I suspected a faulty MAF but have replaced it with new Bosch and still remains. The other disturbing thing is the fuel trim (short) is at -23% which is large correction I think. The only thing I think is suspect vacuum leak. I can post video demonstrating the symptoms if that may help. Björn (Nalle)
