Hey mate, those signals are serious. What OBD reader do you have?

 

I have a ordinary obd 2 reader its not something special but it reads engine codes

 

Stored codes may not be available via your reader. GM is finnicky. The icon with the car and the spanner plus the engine power reduced could indicate a lot of things. I had it when I had injector teething. Unless you have DTCs, not much help we can offer

 

The car with the key icon, went off in less than 10 seconds, the other for the reduced power stayed on for maybe 5minutes, but i was downhill driving 50km/h and i couldnt detect loss of power, but after that on the uphill, there was definitely no loss od power, i will clean the maf and the map sensor, and i think the fuel filter might do this issue, because i think it wasnt changed in a while, i did an oil change with all the filters exept the fuel filter, i havr the car since april and i have made around 5-6k since then, also the other check engine, has never showed up

 

Agree with Aussiecageman that reading GM codes needs an OBD reader capable of reading GM codes (not just basics).
You've not mentioned any consideration of the DPF which can cause loss of power. If changing fuel filter read up on this topic to avoid getting trapped air in fuel line.

 

I dont have any dpf problems, few months ago the dpf light came on an was blinking on every 600km range, and i was taking it on highway driving for 20-30min above 2000rpm and would went off but this summer i was driving the car a lot on open roads, in high speeds and now it doesnt shows up at all, it hasnt showed up for more than 1500km, does it has to show up or its normal

 

Okay, if you can rule out the DPF then that is good. If you regularly undertake some distance driving then regeneration should take place automatically in the background. It is short around town driving which the Captiva does not like because it fails to complete the 'burn' process to clear the DPF.

It might be a good idea to amend your vehicle Sign Up details so as to include the vehicle year/variant in the lefthand data pane (or footer info). This way it will automatically show your vehicle details when you post about something else. (You have used your vehicle data as your 'topic' rather than a topic caption).

I can only suggest that you monitor the situation and see if it was a 'one off' event, but if it reoccurs then post again. Good Luck.

 

It happened twice, both times on downhill, plan is to clean the maf and the map sensor, then put more than half a tank of fuel, and drive the same downhill, on the next service interval i will change the fuel filter as well

 

@Aussiecageman has already told you that you need to get your vehicle system scanned with proper diagnostic equipment. Use the Advanced Search section to look back over his posts for examples of equipment that he specifically recommends, otherwise get yourself a genuine copy of OpCom

As an aside, you could get a transient over-boost condition eg by going uphill at wide throttle opening and max turbo boost to rapidly going downhill with foot off but in general if you get a warning light then a fault code will have been set. Just a matter of getting the right equipment to search for it. If all else fails, have a look at live data.

 

Ill keep my obd plugged in, that way if it comes back again ill test it, also the regular check engine never appeared

 

Here how the map sensor was, it was never cleaned, i cleaned it and cleaned the maf as well
