    Immobilizer Delete For many VW and Audi cars


    kermatdi.com  offers an immobilizer delete service for all VW/Audi (VAG) cars.  This requires sending the ECU to our service center in Utah.


    Most ECU's are $155  although some ECU's may require an extra charge

    Q: How can I tell If I have an immobilizer problem?

    A:If your car will start and run, but shuts off immediately, with the "car in key" symbol lit on thedashboard, then you may have a faulty immobilizer.   An immobilizer delete may help. Please see the demonstration in the video below.  The antitheft provision of the immobilizer shuts off the engine if the car is started without a matched ignition key.  (or if there is a problem with the immobilizer system itself)   There should be a fault code stored in the ECU (P1570 or 17978 fault code indicates "Engine start blocked by immobilizer") 

    Q: My car doesn't run! Isn't this always caused by the immobilizer?

    A: No. If the car does not start and run at all, then it’s NOT caused by the immobilizer.   If the car runs for a few minutes then stalls out while driving, it is NOT caused by the immobilizer.  If the car runs rough, or misses and stalls, then it is NOT caused by the immobilizer.  Likewise, deleting the immobilizer will not help if the no-start is caused by something like a dead battery, out of gas, or some other mechanical problem.

    Please note: If the car does not start and run at all, then it’s NOT immobilizer related.  Deletingthe immobilizer will NOT help if the no-start is caused by something like a dead battery, out of gas,or some other mechanical problem.

    After you purchase this product, you will be sent address and instructions for sending it in.


    What is an immobilizer?

    All VW and Audio cars since about model year 2000 include a factory anti-theft system.  This anti-theft system includes something called an immobilizer, or "immo" for short.   When it’s working properly, the immobilizer allows the engine to run if the correct key is used to start the car.   However, a malfunctioning immo makes a car undriveable, because the car shuts off right after it's started!   With a bad immobilizer, the engine WILL START, but NOT STAY RUNNING for more than a second or two after starting.


    Fortunately there is something called an immo bypass, otherwise known as an immobilizer "delete".  This reprograms  the Engine Control Unit (ECU) immobilizer function, so the ECU ignores the faulty immo.  With the immo deleted, the car will run independent of the immobilizer, even if the immobilizer itself is defective.  As their VW and Audi cars age, many car owners welcome this immo delete, which allows them to drive their car when the immobilizer is broken.


    Other reasons to delete the immobilizer:

    • Sometimes you lose a car key, or need to make an extra key for your car.  These will also trigger the immobilizer, and the car won't run.  Reprogramming at the dealer can be expensive or inconvenient.
    • Immobilizer delete lets you add a remote start feature from an aftermarket security system.  Otherwise the immobilizer will prevent the car from running without the special key in the ignition, which kind of defeats the purpose of a remote starter.
    • ECU goes bad and you wish to replace it with a less expensive used ecu  (We can duplicate the data in your existing ecu over to the replacement in this case if desired)


    Well, how does an immobilizer actually work? It goes something like this:

    • Shortly after the engine starts, the engine computer asks for the "ok" from the immobilizer module (which is physically located in the insturment cluster).
    • The instrument cluster looks for the presence of the "chip" in the ignition key, through an antenna in the steering column.
    • If the signal from the key is detected, the instrument cluster tells the ECU "ok keep running"
    • If the signal from the key is not detected, the instrument cluster tells the ECU "not ok" and the ECU shuts off the engine.  The instrument cluster illuminates the "car in key" lamp to indicate an immo problem, and a fault code gets stored in the ECU.


    The immobilizer has at least two components: The engine computer and the module in the dashboard.  Sometimes there is an alarm system, which is the comfort and convenience module (door locks, flashing lights, etc.)  The instrument cluster has an antenna that detects the transponder "chip" in the ignition key.  With an immobilizer delete, the Engine Computer doesn't ask the instrument cluster about the immobilizer.  In other words, the car with a faulty immobilizer will still start and run - with an immobilizer delete.


    >>>>>>>>>> PLEASE NOTE: it's important to emphasize, not all  "no-start" issues are immobilizer related. There are a number of reasons why a car won't start!. If it's the immo, the "car key" light will be flashing in the instrument cluster.  The car will start, run for 2 seconds and then shut off again. There will be "immobilizer fault" codes stored in the ECU memory when scanned with an OBD code reader. For VW this code is described as:


    17978 - Engine Start Blocked by Immobilizer
                P1570 - 008 -  - Intermittent


    What about the flashing light?  While the car will run normally again, an engine immobilizer bypass won't always fix all the other symptoms of a faulty immobilizer caused by one of the other components.  For example, the dashboard light may still blink, if the immobilizer problem was caused by a broken antenna pickup, or a broken transponder chip in the ignition key.  This is because the actual immobilizer function is NOT in the engine computer, it is in the dashboard.  Immo delete separates the dashboard function from the ECU.  In other words, although the engine controller ignores the immo input from the instrument cluster, the immobilizer in the instrument cluster may continue to complain with a flashing dash light.  However, at this point, the flashing dash light is of no functional consequence.  It is merely a nuisance once the immo is gone from the ECU.  The answer to a flashing immobilizer warning light in the dash after immo bypass, is simply to physically remove the light bulb from the dash!


    kermatdi.com  offers an immobilizer delete service for all VW/Audi (VAG) cars. This service requires removing the ecu from the car, and sending the ECU to our service center for the repair. Please feel welcome to call or e-mail us with any questions! (info@kermatdi.com / 877-537-6283)

    AUDI A4 Quatro Owners (03-07)-- If your ECU part number starts with 8E0 there may be an issue with the car alarm. We can delete the immo, and the car will start once again. However... after you start it, the horn will honk and the side marker lights will flash for 4 minutes. This is a car alarm situation that is unique to these Audis. We can't do anything about the factory alarm with the immo delete.We can alternatively retrieve the pin code for a nominal charge, which will allow adapting a new ecu and keys if needed. contact us please for details

    1. 100% The Best

      I had an immobilizer deleted from my ecu. The dealership wanted me to tow my car 30 miles to them and then pay $300 for a new key. These guys saved me at least $350. Thanks again. on 2nd Jan 2018

    2. Delete immobilizer

      These guys are a great company to work with .The few times I have dealt with them I have been very happy on 20th Dec 2017

    3. Great Customer Service!

      The delete worked like a champ! These folks are also VERY customer service oriented and even answered e-mails after hours and on the weekend. I highly recommend this company! on 1st Nov 2017

    4. Works Great!

      Works great! I got the ECU out, sent it in for a delete, and it resolved the "immobilizer active" error. It's great to have my car running again!

      Good luck getting the ECU out of the car, but that's not a problem with Kerma TDI. :-)
      on 23rd Oct 2017

    5. Great service

      I sent in a replacement ecu for a car I had bought that had a bad one. This was a very easy process dealing with kerma and they will continue to get my business! on 17th Oct 2017

    6. As Promised

      Had trouble with the Bug for over a year,after having Kerma TDI do the deletion ,problem solved.Would highly recomend spending the money,to finally fix the car!!! on 16th Aug 2017

    7. Kerma TDI : Real professionals

      After going to 2 private shops and the dealer, Kerma TDI was able to do what the others could not. Their service saved my Beetle from the wrecking yard, and is now an awesome vehicle once again. Can't thank them enough and they will always get my business!!! on 15th Aug 2017

    8. Problem solved

      I purchased the immobilizer delete for the tuned ecu from my old (retired) golf, for use in my new to me 05 jetta wagon that I had already installed all my upgrades on from my golf. I was able to keep driving my jetta as it was with its stock ecu while the golf ecu was in transit to and from kermatdi. Kerma performed the delete the same day they received it and shipped it back to me right away. I installed the ecu and it works flawlessly. Now my jetta wagon performs just like my old golf did. This was an ideal solution to a vw problem. Thanks kermatdi! I'm a happy camper! on 23rd Jul 2017

    12. awesome, fast, don't go to your dealership!

      Taking out the ECU was very fast, the people from KermaTDI were very helpful and responsive, both on phone and email.
      I sent the ECU on Thursday and got it back on Monday (although they sent it back on Friday).
      Installed it back, and poof, voila! My car was running again!

      Honestly easy, and great service from KermaTDI! Thanks to all the team to be so efficient and nice!

    13. It worked, but perhaps created new issues

      The car started immediately and ran. But I am unable to get the instrument cluster to function properly. No tach and ABS, brake, check engine, low oil etc warning lights are on, though there were no previous problems in these areas. I'm wondering if somehow the computer was re-programmed for the wrong model? Is it possible to program it for a diesel setting when it's a gasoline engine? I had written the VIN clearly on the ECU itself. So, yes, the re-write overcame the immobilizer issue. But it seems to have created a whole host of new issues. -- Still perplexed in Canada. on 23rd May 2017


      So glad I found this service rather than pay $125/hr. at a dealer to have them "fix it"!! on 22nd May 2017

    15. Back to running

      Thanks to Kermatdi my MK4 GTI VR6 (afp) is running again. Fast and easy p.s VW Dealership was no help to me. on 20th May 2017

    16. Thank you

      Worked as expected! I'll recommend to other people! on 31st Mar 2017

    17. Great service

      I'm doing a tdi swap in my jeep and the immo delete alowed me to run the engine off ignition power without a factory key or cluster. This is a great product and company. Very fast and efficient. Saved me a lot of time and money. Thank you kerma on 20th Mar 2017

    18. great service

      I purchased the Immobilizer Delete service for my 2003 GTI. The service received from KermaTDI was exceptional. Their technical service was very friendly and accurate with all their information. Their help made the repair much easier. The unit was received, delete service was preformed and the ECU shipped back the next day. When it was installed it worked just as promised. Very happy with results.

    19. SHE LIVES!!!!

      When I took my 2001 VW New Beetle to the dealership I was worried she was toast because nobody seemed to know how to fix her or figure out what to do. After some research of my own I found reviews for similar issues of similar cars. I talked to the dealer to have them inquire about it. We felt that it was a good match and I ordered the part. The mechanic installed it and Boom! My Beetle was alive again!! Thank you so much!! on 13th Feb 2017

    20. Immo 2 removal works great

      Having my Immo 2 deleted was a big TODO item and KermaTDI did it very well. It was a fast turnaround with good communication. Very happy with the service. on 26th Jan 2017
