When you say change ecu with keys what do you mean? Because the car is having immo so if the ecu got bad you just needed to swap eeprom and the car would start with its original key

Hi,

bought used ecu with matching keys, so i assume. (or they riped me off?)
mouted ecu and tryed to start.
same issue.

also tryed the programming, 4 times now.
left car on ignition for 1 hour.

the keys has to go with the immo box and you sync with ecu in your case you bought ecu with keys witout immo box
so i think your best short is to try and to sync the ecu with original keys

ok, good info.

will try asap

[Brown012]

did you manage to solve your problem
keep in mind the sync process time has to be
exactly 30min not more

Hello
you will need complete kit not just ecu and key as Brown012 said

ok, update on this story.

bought a new immo box, tryed to pair it via diagbox.
computer says succes with pairing.
then tryed several keys to program with the 45 min with contact on.
still no luck.

what i noticed, when i put 12v onto the fuel pump and pump stays on, it will run for a sec.
then shuts off like a immo problem.
but when i look for data in immo box? it say the master key is in the ignition.
very strange

Update.

engine is running!!!
found several burnt wires in the main engine harnass.
just behind the airfilter box.
the 1 of the 2 immo cables that connects the immo box to the ecu was broken.

it will run if i put 12v onto the fuel pump.
so there will be an issue with a relais or broken wire, but will figure that out.

best regards
