Hi all, I have a bizarre and seemingly random 'cold' start issue, I say cold but the outside temp doesn't affect this issue just that it occurs usually in the morning or on first start up. I can go weeks without this issue and then it rears it's head again! I will be turning the engine over sometimes (usually) until the oil warning comes on, I will continue turning the engine over and over( on one occasion I ran the battery flat) and it will eventually begin to start spluttering into life and eventually fire up!!? it's as if it's starved of fuel?! I was think of changing out the glow plugs as a starting point but any ideas would gratefully received. The car has done this on and off for some time now.

Bkd cold start issue
- Thread starter Rich07
- Start date
Everything is seemingly sweet?? No issues, the unit is actually a recently fitted recon and was fitted about two months ago after a catastrophic failure of the old unit! However this starting issue was the same on the old unit, so at least I know it is an auxiliary issue.
Ok so just heard back from garage and the glow plugs are all fine!!?? they have checked everything and said all is fine?!:/ battery good, cranking ok, running good. So he then says to me do I ever let the fuel run low? To which I said I do let it drop below a quarter( I didn't mention the day before I ran it until it said 20 miles of fuel remaining) so before we start throwing money into the dark he says try keeping the car above half at all times and see how it goes before we press on, he also said the tank on the Altea is quite large so keep it topped up! half is my new empty! Tbh I should know better!! Muppet! So maybe the pickup is drawing air or crap in when too low!??? after all it runs and starts fine after such incidents. I've got to be honest I regularly run it below a quarter, it just seems bizarre that a modern vehicle can suffer such things? That I never entertained the idea......anyway we'll see....to be continued....or hopefully not!! I'm also going to avoid supermarket fuel also.
Ok so I go to pick up the car today and they said diagnostics showed everything was fine BUT however he then showed me a print out of a test of the starter motor which showed it had a cranking speed of 210 rpm and he said ideally the cranking speed should be at Least 280-310 rpm, so because it is not cranking at the correct speed then the fuel may not always be delivered how it should. He said he cannot guarantee this is what is causing my random bad starts but it is the only thing that showed up to not be as it should, so £150 for a bosh starter motor plus fitting plus diagnostics prob looking at £350, I was toying with fitting a second hand stater myself but tbb starter motors have a hard life so scratched that, anyway we'll see.
Btw the engine failure of my old bkd unit was caused because of an issue with my DSG auto gearbox, it would get to a random gear then simply not shift at all!! Although it worked in manual fine. so i say to the missus one day, do NOT use the car in drive!??...well you guessed it!!! not only did she use it in drive she couldn't hear the engine screaming for its life because her music was so Loud!!! Foot down on motorway stuck in a gear.....bam!! Anyway there were no eruptions over this lol, but as the old saying goes a stitch in time saves nine!!! I should have never let her take it out and the moral of the story is don't let little niggles linger, It turnt out the gear box problem was a minor issue but caused such devastation....
Try Mister Auto (www.mister-auto.co.uk0 for a new starter motor. App £40 delivered to your door and very easy to fit
Yeah £150 does seem steep, £40? what brand mind? Is that a recon one? yeah I was going to do it myself but literally they had it on the ramps with the keys to the courtesy car in my hand before I could blink lol a lot of the cost has been diagnostics also. Ta I'll check that out thoa, maybe I'll query the dealer with prices might get a discount
Yeah I also noticed that the £40 starter motor states a different engine code? the only one mr auto has is the valeo brand one which is BKD code, also it has eleven teeth whereas the others have ten? Weird maybe different teeth numbers for different transmission?
All I can say is that I bought one for my car. It is a bosch identical to the original and it cost (from memory) app £45 and was delivered within 24 hours from Lyon France.
The fault on mine was that the solenoid would only work the motor intermittantly.

Well got the car back now and all I can say is massive difference!!! I am in tune with the engine (sad I know) and wondered if id notice the difference being that we are talking about 80 rpm difference, but the new starter is so much more punchy! Make you realise how duff the old one was! Even the sound of the starter is much more crisp, compared to a more dull sound of the old one ( I kno sad! 
anyway I'm still not counting my chickens!
anyway I'm still not counting my chickens!Quick update still no problems, however I did change out the fuel filter also, just a tad dirty

'Ish since I had the starter done , and this morning the car had another bad 'cold' start! Like I said it's not in relation to the actual temp but rather first start up after being sat overnight. It took about 20-30 seconds roughly to start up, they said the glow plugs were fine but I may just have them changed anyway, seems a logical area, as when it fires up from cold it runs great!! like I say for weeks on end.

Hi,
I have the same issue with my 2005 Toledo, BKD engine for 10 years now. I have a theory (do not laught!) - when some temperature sensor gets direct sunlight then ECU may be working in "warm-start" mode using less fuel. My car starts even in -20C properly but sometimes "badly" in sunny days...
