Not running to good

[Brendanmck]

So took the car out for a blast tonight for the first time in a while. normal routine of getting her up to temperature then on to the motorway (quite at this time of night) to open the taps up was cruising along for about 10 miles when all of a sudden the engine started spluttering and misfiring the car was vibrating yellow engine light came on as well I pulled over the engine sounded rough and the wired vibrations were still present . Any thoughts guys any advice much appreciated.

One of the coil packs

Could be a lot of issues really. Could also be a faulty throttle position sensor.. do you have the means to get your codes read? I think that would be the best option.

coil pack. Perhaps head gasket. You need to get the code read.

[Brendanmck]

Hope it's something just like a coil and nothing more sinister.will find out in the morning as it's being looked at then.

Don't worry i think Gregor didn't mean to say that its likely that your head gasket failed but he tried to give you an impression that it can really be a range of things causing your issue.

Coil pack,bet you a tenner

[Brendanmck]

Glad I didn't have that bet bounce I'd been paying up. So turns out it was a coil pack cylinder number six to be exact also the computer has shown the throttle sensor has been playing up and exhaust temperature sensor as well so a few jobs for the winter. Its all money with these cars:bigcry:
Thanks for all the suggestions

Gathered that but yea when these cars play up it really can be a mine field that can do real harm to a mans bank balance :hahaha:

Yes, can be any number of things when lights start flashing. I had a coil pack disconnect itself halfway through a track day. Car suddenly started running on 5 cylinders. I didn't know what to do first. Change my underwear, or just go straight to the long walk of a short pier. :hahaha:

I would replace the Coil and clear the codes and drive until they pop up again.

I had a similiar issue last year, car sometimes went into limp mode all of a sudden. It gave me a number of faults when i read the error codes, EGT Sensor, post cat o2 sensors, Throttle Position sensor etc.
Goes without saying that i replaced the EGT and o2 sensors only to find out that the culprit has always been the throttle positon sensor :banghead:

[Brendanmck]

So car is showing a fault with egt sensor(one ordered and waiting to be fitted) just wondering what the symptoms are of a faulty sensor reason being took the car for a spin today driving perfectly then when it got to full temperature as I was exiting a roundabout the car started hesitating on acceleration it was spluttering up to speed is this related to the egt sensor or have I other issues to address any thoughts ?:bigcry:

Vanos solenoid maybe it causes hesitation and loss of power.

[Brendanmck]

Vanos solenoid maybe it causes hesitation and loss of power.

would a fault code be logged for a faulty solenoid or is it trail and error. Is it expensive to change a vanos solenoid?

[monkeycsl]

My m3 showed many codes and we narrowed it down to solenoid.
Hack engineering do uprated ones with viton seals.
Could be many things though!
