330i M Sport 2006

Sun18 · 06-28-2019, 03:43 AM

Hi Guys,

After narrowing down my slowly increasing little issue, for the last month my first cold start of the day has been slowly getting worse. Say the normal start goes like d d brooommm. Now it can be like d d d d d d brooomm like it is struggling to catch spark ?.

When it’s warm and running it seems fine and stable tick over ? And still goes like a train it’s just that initial start up .

Also when warm it seems to start ok ?

Shall I just put a new set of spark plugs in and see if that cures it ?, as don’t want to ideally but 6 coil packs and then it’s the same ?

Any help gratefully received

Thankyou

How olds your battery?

GreenMeansGo · 06-28-2019, 08:25 AM

Had a similar issue. Check your ground strap, mine was deteriorating and needed to be replaced.

Battery 1.5 yrs old and that seems ok , will check ground strap. Big service just over year ago jan 2018.

Like I mentioned when warm she seems ok and runs ok . It’s just the start when cold ?

Might not be electrical at all.

For example, could be leaky injectors or fuel pump issues.

How many miles has the car done?

Sun18 · 06-28-2019, 11:21 AM

it’s weird as when warm she starts ok , just a lag start from cold only ?

Are there any fault codes?

Mine is the opposite, starts quickly from cold but sometimes spits the dummy when warm.
But it is so intermittent at the moment I have not investigated at all!

No fault codes guys at all , car has done 130,000. But always had any work immediately done by previous owner, car is actually mint for age. Could it not be as simple as a new set of plugs ?

I wouldn't have thought so but you never know.

When were they last changed and what do you have fitted?

Sun18 · 06-29-2019, 03:25 AM

Not sure sorry what was fitted ?, but all I know is that just before I got the car it was serviced jan 2018. Oil , plugs , filters .

Could maybe be a coil pack on one of the plugs maybe ? But there’s 6 , and like i say when it’s warm it idles fine tbh, so I couldn’t even do process of elimination and go through eliminate that, I’d have to buy all 6. Which I did see on eBay a set from China for £70 but not sure of quality ?.

It’s just that initial first catch she sometimes struggles / takes a little longer to fire up ! Then it seems fine when warm ?
