Since I had 1 injector replaced they carried out an ecu update and now I have a flat spot when pulling away I have had the vehicle back to the dealer and they say that the ecu can not be returned to the previous version so I'm not happy about it and need to phone customer care again and see what the say.
The injector problem us also known in other countrys. The software update reduces injection quantity to reduce carbon build up on the nozzle tips which are most responsible for the known problems.
On a dyno a "pre update" car had 185hp/393Nm, after the software update these numbers reduced to quite exact official numbers, 170hp/350Nm.
I guess thats the power loss you feel now.
Customer service is right, they cant Put on the old software because then you would suffer from carbon build up again.
Regards, Alex
