I have a 1999 V70 10 valve. Last year the check engine light came on intermittently when driving. Performance etc was normal so I ignored it. After several weeks it stayed on permanently. The Volvo workshop read the fault code and diagnosed a faulty ignition coil which they replaced.
No further problems since then.

Go to a parts store and run a free diagnostic test. It will tell you the codes that have popped up and then you can fix it from there. That light means the computer is sensing a problem.

Engine management light reset


The car is trying to tell you something - limp mode is there to protect the engine if a serious problem is detected. Stop driving it and get someone out to scan the codes and diagnose this.

The check engine light is on whilst driving full time


The Four Most Common Check Engine Light Scenarios and What to Do:

The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

I suggest scanned the PCM to know exactly what fault code is stored there.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Mondeo diesal 2002, glow plug light


Hi

The glow plug coming on on the Diesel Mondeo is an engine management fault indicator. The car goes into "limp mode" when this happens or in other words safety mode is triggered. This explains your loss of power.

To find the cause of this light coming on - the car will have to go on an OBD scanner at a service shop which will read the codes stored in the cars computer and give you an answer as to what is causing the fault to show.

Hope this helps - please remember to rate my answer as ratings are important to me as an expert on the site. Thank You.
