Just another thought and probably clutching at straws. Is there anyway that the solenoid has failed open? Therefore even though it makes a noise it is not actually closing? The low Ohm reading is still bugging me a bit, but maybe this just suggests that this is on its wy out also.

Thanks again logray. Looks like I need to shop around for a few quotes as I dont fancy doing this one myself, solenoid would have been Ok but this is a bit to far out of my comfort zone. Maybe it is time to cut my losses and get rid of it!

thanks logray. I just tried activating the solenoids with the engine running a you suggested. When activating bank 2 idle gets worse however activating bank 1 there is no change. I guess that this confirms that bank 1 actuator has failed in the open position. With both solenoids disconnected and engine running it did seem to idle better. Whilst investigating today I have also found that spark plug 5 has an oil leak but i guess that this shouldnt have any effect on the solenoid error being thrown. Also, possibly unrelated I appear to have to top up my coolant every couple of weeks as the light keeps coming on due to being low. I am hoping that I jut created a small leak somewhere when I replaced the oil filler tube a few months ago. Josellama - were you getting P1531 error code also?

Right, quick update. I have ohm'd out both solenoids (bank 1 and 2): bank 1 = 12.5 Ohms bank 2 = 13.1 Ohms I also applied 12v directly to each one, both made slight tick noise, tbh I was expecting it to be much louder. Also, I was expecting the bank 1 to not react at all or at least hear a noticable difference between them. I also checked that 12v is getting to each one with the ignition on, all ok. Do you think that this suggests a failed actuator? I dont really want to replace the solenoid just to have to go back in again to do the actuator, but on the other hand I dont want to replace the actuator if there is no need especially given the cost! Any suggestions, do the ohm readings suggest a ba solenoid? Can you service/repair the actuator without replacing it? Also, I monitored the camshaft deviation for some time, it is dead steady at 23 degrees and never changes. Cheers

Many thanks to all. I will have a read and keep you updated. Just for info all codes except for cam related have been regularly occuring for the last 10 months or so Cheers

would this also account for the 1124 and 1126 errors?

Thanks for your reply. How do I test this and is it an easy job?

I should note that this car seems to rev fine and pulls great above 2500-3000 rpm

I have been having problems with this 986 for over 14 months now. So far I have replaced the following: new MAF new AOS and all bellows/tubes new coil packs cleaned throttle body, ICV and new gaskets O2 sensor oil filler pipe (due to a crack) The problem I still have is erractic idle 800-1000 rpm and a slight misfire. I have followed this forum all this time trying to resolve this problem with suggestions from other users posts I scanned with durametric and have the following error codes (actual values shown below): Note that I am most concerned about the camshaft errors as these have never shown up until now (from what i have read 6 degrees is valid range and as you can see mine is well beyond this). I still suspect that i have a vacumm leak somewhere as I do hear a howl from the fuel filler on occasions. I am at my witts end now after all this time and any help will be much appreciated.

Hi, Please can you help, I have also lost my code. Becker CDR220 Type 4467 Serial 5011666 Thanks Darren
