    So I sent my ECU (DME) to get it checked and repaired if need be. Turns out the programming was corrupted (so they say) and they have to reprogram it to my specific car. Does this sound right??? Thanks V

    I finally decided to just send my DME (ECU) into Specialized ECU Repair. BUT....along with ECU and Immobilizer they want the steering lock module which I believe is located above the steering column. Any hints on how to get at it. Service manual shows 2 long bolts at the top of the column then it looks like I can drop it down and remove the module..... I got it. The repair manual had not very specific pixs. Thanks V

    Hi All, Having issues with variocam solenoids and starting to narrow it down to bad dme wires on bank 2. I checked continuity between the solenoid connectors and DME connector #5. On the Bank 2 side I get continuity with all pins 1 thru 9 with no continuity to pin 5(ground) when both leads were tested from the solenoid connector separately of course. Hope that makes sense...In other words...pin 1 on solenoid connector has continuity with all pins 1 thru 9 with the exception of pin 5 (ground.) Same follows suit from pin 2 on solenoid connector to DME connector. Continuity on all 1 thru 9 except pin 5 ground. Bank 1: Continuity between solenoid (grey/red) and pin 7 on DME harness. Pin 2 solenoid(red/blue) has continuity with all pins 1 thru 9 with the exception of Pin 5(ground) AND Pin 7. I'm assuming both banks should have the same results(I could be totally wrong). Any help?

    Well I cleared it a bunch of times and it always returned. I'll run it for a bit see what happens now after the swap. . . And....the solenoids not activating is a totally different issue? Or is it related?

    Cylinders 4 and 6. I swapped the coils and plugs with 1 and 3 and ran the car for a bit with no cels. So not sure what that means.

    Ok, Getting back to the issue here. (I took a break) So I have 2 issues the 1.misfires and 2. the solenoids not turning on? I thought the solenoids not engaging would cause the fault code but I suppose the solenoids aren't activated until a certain RPM is reached. V

    Same results with new relay. I then checked voltage on each wire of bank 2 solenoid. 14.9 red/grn with little or no fluctuating when revved. 14.6 on brn/gry with lower voltage when revved...maybe down to 10v So kinda lost here. I guess I could swap plugs/coils see if it follows, doubtful cause they were replaced. Then check for low resistance in the wires from solenoid connector to pins for DME. Was looking at wire diagrams but couldn't find pin # on any DME connectors for red/grn and brn/gry wires.

    Ok, Ill report back after I try the new relay. Thanks again. V

    Right so one part of the circuit is shared...so it still might be the relay....no?
  10. vza
    Crap...had my hopes up. Maybe theres 2 circuits downstream from the relay...spitballin here!! I'll try the relay anyway. See what happens. Maybe the relays totally shot, I did have a hard time starting at one point. Car cranked but wouldnt start. Then it did after a number of attempts. Briefly looked at wiring diagram. Both Red/Blu are shared with both solenoids maybe thats the issue with the relay?
  11. vza
    Makes sense. Fingers crossed. Thanks JFP

    I ordered 2 Bosch relays for 17.00(one spare) it was easier than checking all the voltages, especially on bank 1. Figured I'll give it a try. Would a bad relay cause the solenoid in both banks not to activate? Thanks V
  13. vza
    Ok maybe that's the wrong one in the trunk I found, I'll look under dash and get back. Thanks again

    Ok, thanks John great help. Where is this relay bay in the footwell near the fuse box. Don't recall anything in the engine bay.

    Hobbyist mechanic so bear with me. ...1st off not too sure how to check voltage on each pin. Do I ground multi meter to engine and just use the pos lead on multimeter to check voltage from those 2 pins?(one at a time) I just had the multimeter connected to the 2 pins on the connector is that incorrect ? I started investigating DME relay ...is that the same as the ECM relay? There's 2 relays near L tail light in the trunk. One green w 5 pins and one black w 4 pins. Is the 5 pin one the ECM relay? Other may be fuel pump relay. Also remember both solenoids don't activate with the Durametric. I just checked bank 2 solenoid w the 9v battery and it activated as you know. Didn't try bank 1 solenoid cause it's not as easily accessed. Would a failing ECM relay cause both not to activate, if so maybe that's the prob. I noticed it's also intermittent, CEL lights blinks sometimes then goes to solid CEL and then it just goes off sometimes.
