Hi,need some advice.
So just tried to start the car and it was almost like I held the key to long (yet I didn't).straight away engine light came on and voltage looks like it running at about 12 volts on the dash reading.
I drove the car and notice the car os uder powered and check engine kept coming up.
Any suggestions on whats happening?

Probably, in "limp home" mode
as Imoengnr mentioned, your first port of call is to get is scanned.

What suburb in Sydney are you? If you're close I can scan your car for you.
Private message me if you would like

Best not to drive a vehicle if you feel it’s not running well as it usually will make it worse and a good chance you may damage something costing more of the hard earned.

Cheers gossie.
I'm thinking its alternator as volt meter on dash was down to 12v then jumped up to 14v this morning.
Also when check engine does come on does the car automatically go it to a limp mode?

Did the battery light come on or a message "check charging system"
If not I highly doubt it's your alternator.

The body control module varies the alternator voltage based on battery charge and load. It's normal for it to not always sit at 14v

Limp mode means it's serious enough and needs to be looked at asap.

Not all check engine light scenarios put the car into limp mode.

No battery light or"check charging system" came up.
So would a scan of the vehicle show up a faulty body control module or alternator problems?
