I have this car and when I turn on the car early in the morning after I drive it around the day before, it has a lot of smoke coming from the exhaust but it’s only the left exhaust which I don’t understand. But the smoke is usually only there on a cold start and once I start driving it more it disappears. Do you think it’s just a bad PCV valve?

Hey MATT404,

Could you please try to upload a video that shows the smoke?

Do you have a non-standard exhaust system fitted?

If you have an exhaust system fitted which is seperate for each bank front to rear you may just have an issue on one bank.

Is the check engine light on?

Regards, Joe
