This is probably not helpful at all to those who are experiencing this issue... but my '07 Edition 30 always starts instantly, sometimes having been stood for a week or more. I'm posting this response simply to highlight that this clearly doesn't affect all such vehicles and as others have said it does seem odd that there's seemingly no rhyme nor reason to it.

Sorry... no gloating intended!javascript:void(0);

Just to try and clarify why some seem to be fine and start nigh-on instantly, and others longer - it is simply down to the actual pressure in the fuel rail.  Just like when you blow up a baloon (and therefore pressurise the air inside), and then leave it - some baloons seem to stay inflated for ages, and others can seem as limp as a wet lettuce after a few days - well maybe the internal seals within the high-pressure side of the fuel system might be leaking everso slightly on those cars which are difficult in starting!

Just like to say that I went into get the battery changed by vw and apparently on my 2.0 BKD pd diesel its the biggest heavy duty battery they do and i still find it does struggle to start some times. It's  deffo nothing to do with the battery has TT says.

I don't know if anyone else has noticed but if I leave my car for 5 mins after turning it off it sounds like my car is crying it makes a weeping noise every 30 seconds or so I'm 100% sure this is fuel leaking back as it's comeing from the inlet manifold area and it only does the poor starting wether it's cold or not 1st start in the morning so giveing it enough time to leak enough back to just not catch te first time....

Just to chip in with something which may be useful for the manual owners is that in the instruction booklet (what the hell is that i hear you ask  :grin:) it recommends you start the engine in the way TT describes plus as you turn the key to start the engine fully depress the clutch pedal

I've followed this method for start up from both cold and warm and no problems so far *touches wood*  :happy2:

I really am trying to exercise 'car sympathy' with this motor  :jumpmove:

Just to bring up a old post. I have exact same problem with my 08 reg Normal GTi (24k miles), especially now the weather has gotten a bit colder. Every morning I start the car, although it starts first time, It hesistates, almost as if its going to fail and then fires up. I've got the Liquid Golf Gauge installed and that has not revelaed any fault codes. The car has also been dyno'd at Awesome GTi who has said the car is in healthy condition. When speaking to a staff at Awesome, they recommended checking the battery?

Is it worth leaving the car with the garage to have this problem investigated or is this a common characteristics of FSI engines?

Mate, I've got the exact same "issue" with my 2006/06 GTI - I noticed it this morning and panicked a little bit.  However, with so many other owners reporting seeing the same behaviour it sounds like a 'characteristic' rather than an indication of a more serious underlying problem...

My conclusion to this problem was that the GTI's engine has no way of priming like most petrol engines do, since the high pressure fuel pump is driven by the engine. Therefore, cold starts are basically priming the engine as you turn the starter motor, or at least that is my understanding!

It doesn't explain why some people experience no such issue though  :fighting:

*EDIT*

p.s. it would be interesting to see whether there is a link between those who don't hear the in-tank pump prime when the drivers' door is opened, and those who have cold-start issues...

Me thinks the VW stealer has been bullsh!tting you . . . what is the spec on the battery they fitted?

Because below is the 'biggest heavy duty battery' which VW do (that is a monster 110Ah 850A DIN CCA beast):



and i still find it does struggle to start some times. It's  deffo nothing to do with the battery has TT says.
In what way does it struggle to start?

I'm guessing they mean that the starter is turning over just fine, but the engine isn't firing up as quick as it should... i.e. a fuel problem rather than a battery problem.

That noise could be a number of things: there is an after-run electric coolant pump which is mounted low down at the front of the engine near the oil filter, it could be the electronic throttle valve, or it could be the motor for the inlet manifold tumble flaps, or even the purge valve for the evap canister.  It is highly unlikely you will hear fuel leaking (bearing in mind the pressure in the fuel rail).

Don't forget that modern cars can take as long as 90 minutes (or even longer) to go to 'sleep' after locking the car - you can often hear relays clicking and servo motors adjusting during this time.
