Hello, all.
I've got 2006 V70 station-wagon,
I'm getting warning lights, on dash. Red triangle and Battery icons come on at the same time. with service message POWER SYSTEM SERVICE URGENT.
The warning lights (red triangle, battery) go on and off, while driving.
Car has 112k miles. Bought it used, recently.
Engine ref B5254T2, and Chassis 589090
Anyone help describe what service or DIY repair to follow up ?

By the way, 2 months ago, installed a new car-battery as battery light came on.
I'm in process of DIY replacing the PCV Breather kit system ( Had a massive oil leak) Timing Belt Kit ( just due to the mileage) O2 sensor, Crankshaft sensor and serpentine drive belt. Right now, there is a P0036 and P0017 obd codes, Check engine light is on.
Just did oil ( full synthetic) change.
I'm using video on internet to help carry out repairs.
Also, tried to replace spark plugs but the Coil separated in middle while pulling out. So quickly attached it back on the spark plug and hope to read up/video, on how to fix that prob.
Like the car but not happy with all the sudden, costly, repairs after just buying the car.
help !
Thx

 

start by measuring system voltage - car off, a charged battery will be in the 12.6V range. With the engine running you should see 14V+ across the terminals. When you say the lights go on/off during driving, do you mean the warning lights or the headlights? Usual suspects would be voltage regulator/alternator, power/ground cables, ignition switch.

 

thanks. i'll take the car to Advance Auto or such store, to check battery voltages
