i have a problem with octavia 3, 1.6 tdi dsg 7.

Occasionally it happens when starting the engine the vehicle shuts down and then I have to start it manually by turning the dsg gearbox from d to P and turn the vehicle off again with the key and start.  a couple of times it happened in traffic and it wasn't very pleasant because the process of starting the vehicle is going on.

I consider this a skoda safety problem.

the vehicle is under warranty, the service performed a diagnostic test that did not show an error.

the only mistake was the valve air conditioning motor that controls the air flow plus the potentiometer..service claims that this is not the cause of the vehicle shutting down (make a replacement).

the basic adjustment of the dsg gearbox was performed again last week and the cause of the shutdown remained the same.

 

I have seen a lot of vehicles on the forum with the same problem so please help and advice

That sounds to me like the start detent selector is not working correctly. It should only allow you to start the engine when in Neutral or Park.

the vehicle shuts down when starting and the board says start the engine manually ... I have no problem starting the vehicle but when moving

Perhaps you're not saying what you actually mean then. "Starting" is the act of firing the engine, selecting gear and moving off. So what you're saying to a native English speaker is that the car allows you to fire the engine in Drive, and then shuts itself down again before you can move off.

I think he might be saying that the vehicle stop-start system is faulty.  The engine stops, then won't restart.  He then needs to shift from Drive to Park to do a manual re-start.

 

@Klario - Is that the problem?

I start the vehicle ... the vehicle is on, I switch to drive mode D. .I release the brake, it turns off and then the board says start the engine manually. This happened, to me at the traffic lights while I was waiting for the green light ... I keep the start stop off

OK, I may have misunderstood what you meant to say, but the starter inhibit function should be disabled when the stop/start is on.

this has nothing to do with the start stop function ... the start stop with me is always off..just something turns off the engine and that shouldn't happen ... the same thing when you suddenly release the clutch on the manual transmission .... only I don't have it  the jerk just goes out.

OK, I can agree your point, but it's taken us all day to actually understand it. The 2 most likely causes are still either my original suggestion of the starter inhibit, or it could be that the idle speed is fractionally (think maybe 50rpm) too low.

as far as i noticed my works around 70rpm sometimes and more ... i noticed that the shutdown happens in the summer when the air conditioner is constantly on..in the winter it didn't go out.  can't you adjust the engine speed?  even service is not allowed only if there is a sw update for my vehicle.  the service doesn't know what to do next, they send a technical inquiry to the factory ... it just goes on and on and they can't solve the problem.

Yeah, that makes sense. The problem is that the engine speed is fractionally too low for the combined drag of the transmission and a/c. If your main stealer's service monkeys can't adjust the idle speed, go to an independent who employs and trains real mechanics and software engineers.

Da, to ima smisla. Problem je u tome što je brzina motora djelomice preniska za kombinirani otpor mjenjača i klima-uređaja. Ako majmuni vašeg glavnog kradljivaca ne mogu podesiti brzinu praznog hoda, idite kod neovisnog koji zapošljava i obučava prave mehaničare i softverske inženjere.

the vehicle is under warranty until 2024 so you should not do it anywhere other than at an authorized service center

No comment on Croatian consumer rights legislation, but in the UK, as long as the mechanics are trained you don't invalidate the warranty.

he also threw out the fault of the air conditioning damper motors that I hear in the cabin while driving tak tak tak knocking, they claim that this is not the cause of the shutdown ... they will replace the air motors that control the cabin circulation.

with us you are obliged to go to an authorized service center authorized by the main importer

OK, accepted, but remember that consumer rights law varies from nation to nation.
