Title: Engine error code
Post by: Car nut on 14 December 2010, 08:40
Guys, I know a car can sometimes get error codes in the cold whether.

On start up I got my service reminder 1600 miles - no big deal.

But half way on the way to work I got a picture of an engine come up flashing on the dash.

Stopped for petrol, after stopping, it didnt come on immediatly but then has come back on again.

Car runs fine, no burning smells .... Not been under the bonnet yet

Any clues !!!

You need to get it scanned for faults as a 1st step.

Just did a search and it found something about a voltage drop....

is that meaning due to all the services running, eg front ant and rear window heater, lights and radio etc etc....

I only did a 120mile yesterday morning though.  :sad:

Did a search? You need a code reader and it'll give you a numerical code that you can check in the reader manual or search on Ross Tech....

Coilpacks?

Swap them between cylinders and see if the misfire moves.  If it does then replace the coilpack  :smiley:

Fairly straightforward by all accounts.  Being a soot chucking owner I've never had to replace one lol

I know this is a basic question - well it is if you know the answer....

If you stand in front of the car bonnet up, engine cover off.

Is the coilpack on the left cylinder 1  :embarassed:
