Hi Guys need a word of advise here. So last night after work the temp was about 12 degrees
The car started very ruff, it felt like if it was misfiring and the CEL when on, I pulled over turn the car off and restarted and it when back no normal .
Today same thing but now the CEL is on and when driving it feels almost like driving thru a gravel road.

What can this be? Any help will be appreciated.

I think people are going to ask for more details such as what year. model, miles on it, last few services done, gas type used. it helps if those details are provided.

Sorry about that,
08 528i, 59k miles last service was in 11/12 oil change and routine check up.
Gas use is Sunoco 93.

Most likely a coil went bad. Since there's a CEL, many auto parts stores like Autozone, O'Reiley's, etc. should be able to pull the fault codes with an OBDII reader at no charge. My bet is on a faulty coil...cylinder #4.

oscarsrs

thank you, would this be cover by cpo?

phaduman

I would most definitely think this is covered by CPO. If you have CPO and you have a CEL, I would definitely go to dealership first.

Thank you, called the dealer and they don't have appointments till Tuesday.
And today the car feels worse would this have anything to do with the cold weather ? Or just pure coincidence ?

I believe that the cold weather makes it more pronounced, but it is not specifically caused by the cold.

First I want to say thank you guys for the help!

Took the car in on Saturday morning told them I thought it was a coil, he says ok don't worry will look at it,
they called me today to tell me they had to " recalibrate" the system and clear the codes, and that because the car was with less the quarter tank, this could have cause the issue. Hmmm weird when it started happening the car had less the half but ok.

So I pick up the car and jump on the HWY and not even a mile in Boom! CEL on and the hesitation back . Turn right back around, I get there and tell the SA what's going on.
So he calls the mechanic and tells him the car is back same issue and he replies back with " Hmmm okay so maybe is a coil or spark plug" Am like no shit didn't I tell you this? Well anyway it ended up being the coil on cylinder #6 he said.
Just got it back and is all back to normal

So thanks again guys!

Glad to hear you got it sorted.
