GAUGES WORK SOMETIMES/SOMETIMES NOT. ENGINE STALLS OCCASIONALLY

REDUX 1.
NOW KNOWn THE BATTERY IS NEW, but long sessions of CRANKING will make it dead (discharged)
and that you use the wrong words for engines
I guess petrol engine not diesel.
is this auto transmission or manual "STICK"

I think you just used the word CRANK for RUN
that makes sure all my answers will be wrong,for sure doing that.
here is what happens on modern cars.

1key on.
2: immo lamp very angry not happy engine is immoblized next.
3: key turned to ST (start) this means cranking the engine with a stater motor.
4: the engine starts, (and dies 3 seconds if IMMO is not happy< can be look at lamp IMMO)
5: engine runs now, and
6: engine stays running, and does not stall if does stall now say the stall word.

there are 50- reason for engines to stall. and a box of tools gauges, in my kit to find them all and not one do you have. nor how to.(find a shop get the car fixed,)!


if that starter motor is silent say so, or if it clicks or chatters say so.or makes huge BANG spins super fast but engine crank shaft does not turn(see all the ways starters can fail, hint , lots and I can not hear yours.

if starter fails dead then shift PNRDL from park to Neutral and crank the starter in N. (cured?)
key on, CEL glows normal and IMMO not happy can glow.
key on does IP cluster self tests and most lamps there go dead after the key on self test., not all.
modern cars are smarter mine cuts dead all lamps for faster better cranking power, 300amps from battery to starter motor , none wasted on lamps for sure head lamps on my car are disabled cranking,(mine)
what matters is
all fuses good
starter motor aways works.
engine starts
and engine runs and stays running.
and now running the CEL lamp does not glow or worse flash.
tachometer works
shifted to drive does not stall the engine,
car moves, if all is well the the transmission upshifts, 1,2,3,4, etc.

if fails scan he PCM first.

Seems the valves need adjustment.

First is your car still under warranty? If not we are working on an 09 Tiguan that wants to sometimes wants to die out at stops.We are replacing the in tank fuel pump and fuel pump control module.

i would like to ask that only the dash gauges sometimes work and sometimes not .and Did the problem come on suddenly or was some previous action or work done......

Pull crank sensor and look for cracks.The cracks allow oil in and short the sensor out.

Without hearing the noise, there is no way anyone could tell you where the noise is coming from. I would recommend taking your mechanic for a ride to show him what is happening. If it is overheating, your temperature gauge will be high (if you have a gauge) or your water temperature light light should be coming on. Make sure the light works. It should come on for at least a couple seconds when you start your engine. Anyway, if the mechanic is in the car when it stalls, he will no longer tell you that nothing is wrong.

I have the same year and stalls out occasionally in the beginning and now I can barely drive a quarter mile. All of the parts you listed I've tested and appear ok but what I'm thinking is not fuel because it would act crazy gasping for fuel but the camshaft and crankshaft sensors. If either of these are failing then the engine stops firing and dies. Also could be the alternator or battery. If not enough charge then the car could die. Mine dies like I turned the key off (and don't think it's ignition switch) and gauges all just drop to zero still sounds like engine is sort of on until I finally coast close to stopping and then dies and oil light comes on.

loose connection in the wiring somewhere.

GM is known for faulty ignition switch on that model.

This is not a typical automotive problem. This is a serious electrical issue.... maybe related to ignition switch or emission control module. I don't think you'll find a simple answer other than taking it to a dealership for service.
