Do you mean that the key symbol with the car is blinking? If so, the immobilizer is killing the engine about 2 seconds after it starts. You'll have to either rectify it with programming, or get the immobilizer deleted via programming.

Cheers,

You need the original key, the CCM (computer control module) is locking you out. The other thing that may be at play is the dash cluster.
If you have the barrel and key from the donor TDI, swap the dash cluster as well. There's an RFID chip in the cluster and the fob that talks to the CCM.

Otherwise you'll need to have the immobiliser deleted from the CCM.
You'll need a good tuner, and may still get the immo light flashing, but the car will run.

theecu cluster and key barrel with reader was swapped from the donor car do you reckon the coding has been lost ?#]

You need to refine your references. I'm talking about the dash cluster with
the speedo, gauges, etc. The RFID chip in that unit talks to the chip in the
key fob. Once those 2 chips "see" each other, the CCM, the actual computer that runs the car,
which is behind the firewall accessible from the engine bay, allows the car to run. This all means you can't "hotwire" the car.


The barrel you refer to is cut for the physical profile of the key, no electric communications at all. It is handy to swap since now you can
use the original key.



An ECU is any electric control unit. Please be more specific, precision matters!

"clocks were swapped in his first post. English vs. American terminology"

I get that he's talking about gauges, but did he swap the circuit board as well? Because that's where the RFID lives. Did he swap the entire ECU?
The entire cluster?

The CCM is also an ECU, but the references require precise usage.

On an international forum there is a need for universal and specific
terminology. Speedometer and tachometer would have been unequivocal.

I'm well aware of differences in languages, in Cockney rhyming slang,
I'm a Seppo, (septic tank yank).

20yrs downunder mate, and more than a few years in the UK, and Canada. Slang is commonly used to disguise meaning and confuse those who don't speak a local lingua franca. You gotta' be "in" to understand it.

The complexity of German engineering and the need for precision to
have it work properly requires exact references.

@Rrusse11 - BTW, CCM is common short hand for Comfort Convinence Module.

ECM - can be Electronic control module, but called Engine control module BY VW, where as ECU is used as generic electronic control unit. Makes more sense when you have TCM, BCM, and ACM (airbag control module) in a car. Though I use SRS for that last one.

OP is working on MkIVs so sometimes they just need a key on and wait after having everything unplugged. Or worse not powered up together, such as turn the key on to move the car before the ECM and engine was all plugged up.

@declanrbt - That sounds like a fun car!

My bad, acronyms get tossed around here and I've yet to crack all the codes. Usage also varies depending on location it seems.
