This seems a good idea.
I'm searching for a complete set.
But some guys where you can buy such sets are really very strange.
The last one I asked, offered a set of immobilizer, key and "airbag control unit".
When I asked about the engine control unit, he said that the engine control unit doesnt have immobilizer.

Austria, east of Swizzerland, south of Germany.
Ohh thats a good tip.
Maybe they are selling those kits I need.

There are already two of us.
I really dont have any idea how to find out that.
The car is definitifely a german car, no US-reimport.
The spare ECU I bought is from germany too.
They both have exactly the same Bosch.- and sparepartnumbers. (see pic attached)



I think without a 100% good set of key, ECU, and immobilzer it is impossible to go on and exclude this as cause of failure.

I would try to get ahold of a piwis and flush the 986 row tune to your dme.

Hi,

I just fixed one with this exact issue. You need a new key. If you have the ability(I used PIWIS III), you can go to transponder key programming and look at all the currently programmed immobilizer ID's.

Mine had none stored, but would give me a "key already programmed" with my old key.

New key programmed immediately and started up.
