Astra, Corsa, Zafira, Meriva, Adam, Cascada, Agila
I have a 1.9 SRi diesel astra.
It's always smoked a little bit on start up, now it's smoking whilst I'm driving. The engine light is coming on (although didn't come on just now whilst driving) and it seems to have lost it's speed. ie I think it's going in to limp mode all the time.
