Last couple of days I've noticed a decrease in power under acceleration, and some anemic starts.

Today the start took several seconds before the engine turned over.

While driving home, I went to pass some cars on a rural road and had even less power - enough that I knew I wasn't imagining things.

Also, te car seemed to rumble with acceleration.

Finally, I briefly got an orange check engine light that went out, and two blocks from home, the red engine light and "reduced engine power"

Temp was fine, oil level was fine.

Is this an alternator fail or something more serious?

I've got a tow booked for the dealership in the am, but I need some advice and a stiff drink to make it to tomorrow!

By te way, odometer reading is 113,000km on a new 2011 c4s.

Thanks and down the hatch.

 

113k km on a 2011? ?

 

Yes. :-) commute through country highways.

Could be a bad coil
