Vauxhall Astra Exhaust Manifold Problems
Smoke coming from engine area
There is smoke coming from the engine area, the smoke seems to be coming from the area where the exhaust joins the engine (the exhaust manifold).
Check Engine warning light showing on dashboard
The dashboard warning light showing on this page (or one very similar, sometimes a slightly different shape or colour) has appeared on the dashboard and doesn't go off when the car is running.
Engine does not sound or feel normal
The engine doesn't sound normal, it can sound like it's struggling to keep running or out of time. The engine note produced by the engine can also sound very different, it's often a deeper, more bass heavy sound that it is normally.
Car not accelerating normally
When pressing the accelerator down the car does not accelerate as it's supposed to, there is sometimes a lag or delay between pressing the pedal and the car accelerating. The acceleration is sometimes slower than it should be and the car can feel as if it's hitting a limit that stops it going faster.
