Old thread i quickly found might be some info on there?

Wow that was a long read - luckily none of the other symptoms (yet), but hope the battery was the fault.

Will know more tmrw !

I only had a look through 3/4 pages just seemed to be lots of info on different stuff, i will read it when I have more time.
 
Did you get it sorted with the battery?

This is mine this afternoon after 2 days cold

Did you try waiting a few seconds before turning the key? Make any difference?
 
Not had the need to go out today & shattered after a long week at work. When I was using the car after fitting the battery, it was not from a long stand. Tomorrow morning will be the test & will update accordingly.

Hoping it is / was the battery given it was holding a low charge overnight. If it's the car draining it (my other thought after buying & fitting a battery!), then I have more investigative work to do.

Waiting before turning the key made no difference at all.
 
:headbang:

Started it this morning and part way through cranking I sneezed & stopped turning the engine. Started straight away after, but might have been my pre-crank.

Never sneezed while cranking the car before & typically it happens when I want to check that the new battery has cured the slow start! Tonight I will make sure I do not sneeze :thumbsup:

About half the number of cranks with the new battery :thumbsup:

Thanks for all the advice and contributions

I can't get yor vid to work to see if it's the same as this, if so was it just a new battery?
 
Well sort of, it does it less often, but no logic as to when it takes more turns than expected.

Can leave the car for a few days, then it fires on the third engine turn. Other times it is about twice as long as expected. When it does this, it has almost a partial turn and then fires properly. Not describing it well.

No idea why the video doesn't work though! Will check the settings.

No lumpy idle when it starts though, sits at 800rpm stable as possible.

Saying that i was in usa for 2 weeks and the car fired up not even one turn, strange. My idle sits normal after that first funny bit. Not like that all the time
 
I have put it down to a quirk to be honest, but yes that same slight pause in cranking is the same.

Given it fires & then idles perfectly, I cannot see an issue.

Just another unique thing about the cars I guess?
 
Check with your other key too, noticed the distance to lock and unlock was getting a bit longer on my daily use key and was taking a bit longer to fire, swapped to my spare key and the remote works better and starts first time again. Assume the other key battery is dying so taking longer to clear the immobilizer or charging a bit first.
 
Good point. I had that issue with my 7 series where there was something not quite right with the immobiliser code that was being generated and did not always match the ignition. I used the spare key from then onwards and never used my (previous) main key anymore.
 
Il give this a try in a boy consiering the garage said there aren't any apparent issues

***just tried it no difference
 
Interesting will try that also.

Strangely on Monday morning, not having used it since Thursday, it also fired straight away, vs Monday evening where it took a few more turns; cannot be battery related then I'd guess.
 
Only my first two drives, but weirdly using the other key makes it fire on the 2nd crank, much quicker!?

Gets driven for an hour a day, so imagine the battery is on its way out in ine key then & not holding as much charge.
