OK I'll replace the transistor and see if the CEL goes away forever. Fingers crossed...Thanks again V

OK ....resistor not needed thats what I thought. ....so replace with the 373...you think that was the problem....would that allow the actuator not to engage ?? Thanks again for your input ....big help. Vince

Numbers on the transistor 30046

                                                44313.1 any other numbers are burnt and cannot be read useless the chip next to it is the same and can be used as reference. V

Bosch BIP373 Coil Driver Mod Kit from DIYAUTOTUNE is the part I need? It comes with a resistor but not too sure if I would use it. Thanks....looking forward to resolving this. V

here's another pic.

Lo and behold. Well I opened up my DME and found an obvious fried Transistor, would this be the root of my problem? Hopefully!! There was another thread with the replacement part number can't seem to find it. Any help as to where to purchase the replacement transistor would be appreciated. I'll post another pic. Thanks V

OK Thanks Ahsai.....very helpful. V

OK Thanks....I just don't have a durametric....unfortunately!

Viewed other threads and pix of burnt components in the DME....pretty obvious. Is there any harm in unplugging the DME and taking a look see inside? Is it a transistor or resistor that's in question?

Well I believe he said the solenoid was firing.....not too sure how he would know. If there is no active ground in the plug are you just going to ground on any part of the car to see 12v? How would you test the ground coming from DME inside the plug(connecter)? Would there be a visual inside the DME (burnt/char or smell?) Well I know its not the solenoid its new, just wondering about the transistor....that would be an easy fix rather than pulling the cam cover. Is it common for  these transitors to go?? V

Ok...so if there is power at the actuator as the indie said.... there is no doubt its a bad actuator correct? Not the dme or solenoid(solenoid was replaced already). Want to be sure before I start tearing it all down again.

I actually just replaced the solenoid ....not the actuator. Brought it to indie said the actuator is getting power but NOT activating or moving. So I will assume its the actuator??

Hmm....so start tracing??

99 Boxster Base...After new Bank 2 solenoid/MAF/AOS/Battery/Plugs/Actuator Ramps both banks,I'm right where I started CEL P1539 and some misfire codes here and there...Brought  to indie....said bent valves/actuator or timing....bailed on me....car is now at another indie. Any thoughts....car actually runs and sounds well with a little lacking in pickup. Any thoughts??

Ok, I rewired my headlamp harnesses  and all my lights/ fog lights are working as they should. So new headlamp switch is not needed. I did notice the color or intensity is different between my 2 xenon low beams. I read that 1 may not be level with the other. Is this true seems to make sense being if I look into the beams at different angles they both look the same color. thanks v   

99 boxster base..When turning on the fog lamps the manual says to pull the knob to the 1st position for the fronts and 2nd position for the rear. Is the knob supposed to remain in the pulled out position, mine returns back to the normal position so essentially my fog lights only stay on when holding the knob...Just confirming I need a new lamp switch thanks v

Hmm...maybe I'll glue a thin piece of rubber on the face of the switch instead of. buying a switch...thanks v

99 Boxster Base. Both windows don't roll all the way up unless I shim a small piece of rubber between the 'hook' and the latch. Am I correct to replace the micro switch located in the dome light? It only works with a shim .....if I push it with my finger it doesn't work either. Thanks V

Can anyone verify the top bulb is the lowbeam...I may have been misinformed as to which is lowbeam.

99 boxster...previous owner upgraded the hibeam to xenon available from pelican. Lowbeam is still the H7 halogen.Any reason I shouldn't rewire it for xenon on the lowbeam? Makes more sense considering the lowbeam is used more frequently when driving. thanks v

99 Bosxter Base...I need to replace the dome light assembly because of a  bad micro switch(windows don't fully close). So... I have a replacement but its a 2001 I believe. It has a nicer  fixed dome light not the rickety one in the 99. Of course it has a different size connecter. The other connecters for the micro switch and infra red are the same. Was thinking of just fabricating a new harness. There are only 3 pins. I assume 1 common ground and 1 switched and 1 for continuous. Couldn't find the schematics in the factory serve. manual. Any thoughts about this. Thanks .....Hate that rickety one....ugh

Hi,Anyone know if the headlamp switch is serviceable...maybe using contact cleaner. One headlight intermittently goes on and off. It's not the ignition switch replaced both mechanical and electrical ignition already.Thanks V

Not a pro but it may be the AOS ....you can check the tubes coming off the AOS, if there's a good amount of oil there you might consider replacing it. The tube thats running under the driver's side intake is the longer tube that attaches to AOS. The upper dip stick tube can be easily replaced(replace it after you do the AOS cause you will break it again) it just snaps on. The dipstick is weird with mains as well. You sort of have to twist it as your putting in down in the tube. Good luck. v

Anyone know if a 99 Boxster Base console is interchangeable with a 03 Boxster S console? Thanks V

Good article Thanks V
