Hello and thanks for your question. My name is XXXXX XXXXX I will do all I can to help.
So you just see the red triangle? and no text messages in the information window?
Alright, usually this means a door, or trunk or something is open,
This is a V70? S60?
Alright, by chance when the red triangle appears, you don't see a footwell light come on? like the footwell light comes on when you open the door?
The microswitches in the latches can fail and cause it. and you'll see a footwell light come on as well.
If it was the gas cap, then you should get a code. it would be an evaporative emissions code.
and the check engine light would be on. Is the check engine light on when driving now?
That's interesting, usually when this triangle appears you get a text in the message window.
Do you ever see any message in the text window at all?
alright, In my opinion, the scanner used at Advance was the standard OBD II scanner. You may not have any engine codes. But you may have ABS system codes or codes in the CEM (Central Electric Module) that would pinpoint a failure. My experience is either one of the door lock microswitches has failed and the CEM is getting a signal a door is open, or something in the ABS system like a wheel speed sensor or contact ring has set a code there.
You also want to check your coolant level and brake fluid level.
If all fluid levels are good, then you will need to get an advanced type scanner and check all the codes in the SRS, ABS, and CEM.
The engine never overheats when you see the triangle correct?
alright. What I would suggest is reading off all the codes in the modules. In my opinion there is something stored in the other modules besides the Engine control module. (or ECM which most code readers can only read).
If all the modules are clear of codes, then what I would suggest, is have the vehicle hooked to Volvo's VIDA computer interface system. then you can read off the CAUSE of the triangle light in the instrument cluster (or DIM) module. There is either a code stored in another module, or a door switch has failed. But you will have to get an advanced type scanner to get into the other data streams to see what is stored.
One thing you can do is when the triangle comes on, open and close all the doors and see if it goes out then. If you can correlate the light going out with a particular door , I would suspect that door switch.
as long as your oil light isn't on, and your temperature gauge is normal, and the vehicle doesn't have odd noises then it is alright to drive.
I will recommend a tech. He is a Volvo master tech. and has been at volvo for 15 years , name isXXXXX at Volvo of the Triad. That is prob. 70 miles away from you in winston salem however. But he is one of the best in in my opinion.
Alright sounds good. There is a code stored somewhere in my opinion that will point to the problem. OR there is a door switch failed.
Doesn't really say a whole lot of detail and the triangle in the owners manual. this is what it states.
Warning lamp in the center of the instrument panel
This lamp lights up red or yellow depending on the severity of the fault that has been detected.
Yellow light: Follow the instructions shown in the text window.
Red light: Stop the car as soon as possible in a suitable location and read the message shown in the text window.
alright, check all the codes in all the modules. Then get in the data stream of the instrument cluster (otherwise known as the DIM) and you should be able to read off why it's got a code. If it's not overheating and the oil light isn't on. It's good to drive.
