Immobilizer Delete Volkswagen ECU ME7.5 ME7.1 ME7.1.1
ME5 MK4 VW Audi IMMO OFF

Immobilizer Defeat Service for many VW  & Audi cars
with Bosch ECUs
(please note: This listing is only for Bosch ECUs ME7, ME7.1 ME7.1.1, ME7.5)

If you are NOT sure, please send a photo of your ECU before you pay for this
listing.
We can also do diesels and Siemens ECUs but we charge more for those.

 

We offer an immobilizer defeat service for many
VW/Audi (VAG) ECU.  

This requires sending the ECU to our facility center. 

You will be sent the address and shipping
instructions after we receive your payment.

Question 1: 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 the dashboard, then you may have a faulty
immobilizer.   An immobilizer delete may help. 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 or other components)   

There should be a fault code stored in the ECU (P1570 or 17978 fault code
indicates “Engine start blocked by immobilizer”)  

Question 2: 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 is NOT caused by the
immobilizer.  If the car starts 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, defeating the immobilizer will NOT help if the no-start is caused by
something like a dead battery, out of gas, or a bad ECU. 

PLEASE NOTE: If the car does not
start and run at all, then it’s NOT IMMOBILIZER related.  
Deleting the immobilizer will NOT help if the no-start is caused by something
something other than the immobilizer.

What
is an immoilizer? 

When
the immobilizer is working properly, it 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 WILL NOT STAY RUNNING for more than a
second or two after starting.

 Fortunately,
there is something called an immo bypass, otherwise  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 these VAG cars age, many car
owners welcome will opt to get rid of it, to prevent being stranded. 

 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 very costly or inconvenient.
• Immobilizer delete lets you add
  a remote start feature from an aftermarket security system.  
• ECU goes bad and you have to
  replace it with a less expensive used ecu  (We can duplicate the data
  in your original ecu over to the replacement in this case if desired)

What
about the immobilizer light on the dash?  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 receiver, or a broken transponder in the key or
a faulty ignition switch.  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.   

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 for details.
