  1. OPCOM
    My vehicle shows this fault. Even though I delete it, it doesn't go away and my vehicle doesn't see the VIN number when I look at it from OPCOM. I think the ECU has been changed before and the immobilizer has been cancelled. I have opcom v1.70, can I solve this problem with it? Is there anyone...
  2. OPCOM
    Hi Gents, i am sure the more experienced members have seen these posts over and over, this one is slightly different (maybe). I have tried to find the info, but without luck, so have started this thread in the hope, i dont leave with my tail between my legs. Yes, i bought a China fake Opcom. It...

    Hi, sorry if this post is a regularly covered topic. I'm considering buying a decent diagnostic tool but not sure if I want the Opcom route. I'm thinking something more like a well featured professional product that will serve me well if I buy into a different manufacturer or want to help out...
  4. OPCOM
    I've recently been trying to install cruise control into my 2008 corsa d and haven't been able to program the instrument section. Whenever I try and enter the module it throws up an endless loading screen saying 'reading security code... please wait...' From what I've heard I need to downgrade...
  5. OPCOM
    Hi there, I've been having a problem with twitching/surging while driving at 1500-2000 rpm for a while now. The pressure regulator has already been changed and there are no pressure problems (according to live data from opcom). But what caught my attention is the EGR position sensor. It also...
  6. OPCOM
    Hi all. Couldn't find a thread about this yet so thought I would start one. Unsure if there are any people who are confident enough with Opcom to work on other people's vehicles. Maybe good to get a list of proficient users and approx locations if you're up for helping others out. Meanwhile...

    My car is a Corsa E 2016 B10XFT, and am looking to buy an Opcom dongle. Before I take the plunge into buying one, presumably not the cheap eBay knockoff as I don’t think they will work me 3016 car. could someone verify if Opcom can even read the pids I am looking for? I doubt it is going to vary...
  8. Large Vauxhalls
    Hi, Short and sweet question. My Opel omega B from 96 is running slightly hot. Typically runs just under 95 C but never at 90 C. The temperature will creep upwards when at low speed and fans will spin up rather valiantly as soon as it reaches ~98 C (a bit under red) and the temps will go down...

    Hello all, I think this may have been asked a few times before sorry, but hoping someone can help. I have a 2015 1.6 Astra Excite, it's a pretty basic model and the driver display thing doesn't have any trip meter or MPG functions. I recently rang my local dealership explaining I want to add...

    Hi, I’ve bought an Opcom interface for my Zafira, so I could upgrade from CD30 to CD30 MP3. The interface has been working fine up until yesterday, where an error would show up. “Interface communication error, or interface not powered from car”. The ignition was switched on, but it would...

  12. Car Audio / Electrical / Security / Diagnostic Rel
    Hello, I have recently purchased an OpCom diagnostic tool from China, what they call the "pro" one. Main reason I got this was because a friend of mine with an Insignia 2015 asked to buy it so I can check his car as well. Came with software version 200603a, which is cool because I see cars from...

    I have a 2010 Astra H 1.6 Sri, which i just got from another family member, they had told me that the battery keeps draining and after replacing the battery multiple times has confirmed it is not an issue with the battery. I have not yet tested and pulled fuses as i am waiting to receive a multi...

    Hi I wanted to PM a certain someone about an OpCom but I don`t have the cred. I'm looking to fix my 2007 Corsa D that's been used very sparingly over the last two years, battery went flat and now an F is showing and won't crank (but the diesel pump spins). It was cranking before I disconnected...

    Hello everyone! I didn't want to flood the forum with the multiple threads, so here are my couple questions. I've got a Zafira B 2008 with 1.8 CDTI motor, i've read that it is fairly easy to enable cruise control on it with Opcom/Tech2 devices. Could anyone suggest where can i find a...

    I have a 2014 Astra 1.6CDTi that is continuing to say DPF full. I've carefully cleaned the DPF off the vehicle and all seems good. I also replaced the pressure pipes & sensor and also the oil & filter. No errors shown using Carscanner Pro and everything looks okay other than soot level showing...

    I'm replacing injectors and need to recode/recalibrate the ECU. Does anyone have a link to a opcom or similar that I can use for this. Engine code is M9R E 780

    Hello all. I own Astra H Estate 1.7 CDTi 2007 (100 hp). Having some issues with starting the car(no cranking then starts fine after 2-100 attempts) and I'd like to buy OPCOM to see what's going on. Which FW to go for? 1.99? 1.7? Older ones? Thank you in advance.
