    Need some help with service car soon and fault codes.

    Forum Key Rings
    Hello, I need some help with fault codes.

    Symptoms for the car.
    1. The “Service car soon” light comes on when I start the car. (I thought this meant the car needed its 12-month service. I now find out this means there is a fault with the engine.

    2. The car hesitates when accelerating in second gear when the weather is hot.

    I got these fault codes below and more on the first scan
    I am more interested in these below.

    DTC Symptom Byte DTC Description Symptom Description Status
    P0234 11 Engine Overboost - - - Passed and Failed
    P03A7 00 Cylinder 2 Pressure Variation Too High - - - Passed and Failed
    P0403 04 Exhaust Gas Recirculation (EGR) Control Circuit Open Passed and Failed
    P0108 00 Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage - - - Passed and Failed
    P2100 04 Intake Air Flow Valve Control Circuit Open Passed and Failed
    P03A6 01 Cylinder 2 Pressure Variation Too Low - - - Passed and Failed
    P1325 04 Crankshaft Position Reluctor Ring Performance - - - Passed and Failed
    P1325 02 Crankshaft Position Reluctor Ring Performance - - - Passed and Failed
    P0671 00 Cylinder 1 Glow Plug Control Circuit Malfunction Passed and Failed


    I clear fault codes start the engine run car for 3 minutes then scan again.
    I can't drive the car yet as it needs a suspension control arm.

    I got this code after cleared
    P0671 00 Cylinder 1 Glow Plug Control Circuit Malfunction Passed and Failed


    Do you think it's the Cylinder 1 Glow Plug faulty and needs replacing?
    Do you think a faulty Cylinder 1 Glow Plug could've caused the service car soon warning to pop up?
    Do you think a faulty Cylinder 1 Glow Plug could be the cause of the hesitate when accelerating when the weather is hot?
    Do you think a faulty Cylinder 1 Glow Plug could have caused the ECU to show up all those other fault codes above?

    Please let me know your thoughts.
    Regards

    First scan

    Sorry cannot assist with advice, I am interested to see if others say the glow plug can trigger other faults.
    May I ask what device you are using to read the codes? I have tried 4 code readers and none have worked on my car, I had to eventually put mine to a garage and they deleted the stored codes, but now I'll need to go back because service vehicle soon reappeared. The first code reader was a decent quality one which our guys use on the fire vehicles at work but would not read my codes, the other 3 were "cheap" eBay jobs (which probably explains a lot) and were hopeless. One was a knock off version of the op com set up but I couldn't get it to work. Now I'm thinking to try a genuine op com, what device is that your using?

    Hi, I use VXDIA nano gds2 https://www.ebay.co.uk/itm/UK-Ship-V...hmst:rk:3:pf:1
    The latest software can be found here http://blog.obdii365.com/2018/03/27/...download-free/

    VXDIA nano is a very good tool.
    It works fine with GM GDS2 and GM SPS programming with GM SPS subscription.
    You will need VMware software running on a Mac or windows to use the gds2 diagnostic tool.

    Opcom don't work with insignia very well.
    VXDIA nano can be use to read and delete fault codes.
    You can also use it to update your ECU and other bits Via GM SPS subscription.

    I Checked the glow plugs with a multimeter today.
    The glow plug closest to the cam belt cylinder 1 read at 5.87Ω, all the other glow plugs read 0.74Ω
    It seems one glow plug with sensor may be faulty.

    Ah Thankyou for that Tattootroy, that piece of equipment looks the ticket. I was about to order another op-com but now I'll need to mention this one to the lovely other half. Looks like a decent investment. Wish I'd bought one of these years ago.
    Thankyou for taking the time to reply

    The GDS2 diagnostic software is what GM dealers use.
    You can use it to do many things eg. read and delete fault codes, reset or calibrate sensors and modules, Perform the Fuel Pressure Regulator Valve (FPRV) learn, test every module the car has and many more features.
    The VXDIA works with GM tis2web SPS online programming, use for updating all the car's modules with the latest updates from GM server, marry or divorce modules and ECU from the car, program car keys and so fort.

    Lil tip. If you do subscribe to GM sps online programming.
    Make sure to download the SPS software and install it from the gme-infotech site as it takes some time to set up. Gm charges €50 for 2 hours then €35 per 2 hours after.
    If you don't want to use the VXDIAG VMware GDS2 application, you can subscribe to GM GDS2 for one month, when the month expires, just change your laptop date to one day after the date of your first subsription=free GDS2 for life
    https://www.gme-infotech.com/info/tis.html

    Since I bought the vxdiag I've saved a lot of money and time.

    I install a new glow plug today, all fault codes are gone. Fingers cross.

  10. Thanks sriray Thanked

    Thank you for the in depth explanation of the features of the tool. Sounds a lot more what opcom can do. Although pricey compared to the £20 opcom but I think it's worth investing for gm owners.

    Thank you for the information Tattootroy, definitely a worthwhile investment, nothing worse than electric gremlins. At least when it's a physical issue like a worn wheel bearing or discs and pads etc it's just a case of fixing, but electric issues are the worst.
    Thanks again
