Stutter starting issues

[autobahnaudi]

For the last 3 months my car will very very intermittently have starting troubles.

After holding the clutch and pressing the ignition the car will crank several times for around 3-4 seconds and then start.
This happens so intermittently that I don't have a video of it.
Anyone else have similar issues / solutions.

9/10 starts the car starts first crank as it should.

Hi!

I had the exact same problem for about 4 months. Dealer wasn't able to find out why.

No codes, hesitation at startup, sometime had to crank twice.

Changed dealer and found a skilled tech.

It was leaking fuel injectors.

Only way to diagnose is:

Warm up the car.

Stop engine and remove sparks.

Check inside the engine with a small camera.

I had 3 out of four injectors leaking. One of them was leaking real bad.

3 hour job to change all three, they are quite far under the intake, lots of things to disconnect/reconnect.


Something else I had noticed was that the hesitation would happen only when the car had been sittting for 10 to 60 min. You know, not at operating temp nor completely cold. Just in between.

You described my problem to the letter!!
Thanks for chiming in.
Basically while the car is sitting the engine is getting flooded by leaky injectors would have never guessed really.
Got a little bit of warranty left I'll take it the dealer and tell them where to looks.

Where the fuel injectors bad or was it just seals or orings?
