If the Anti pollution warning light is coming on the possible causes are endless. If the car is driving ok then that is a good sign, but please remember that modern management systems can mask problems quite well. The safest advice is to get it looked at and see what fault codes are appearing and then a diagnosis can begin, as leaving it is not going to be a good thing, it can go from a minor problem to more serious issues. At least the light is not flashing, which usually means an emission compliance problem and even more serious, but even so I would advise protecting your vehicle by getting it checked out as soon as possible to avoid potential damage.
----------
A fault in the ignition can cause an engine misfire and unburnt fuel gets into the exhaust causing the anti-pollution light to be triggered.
Check the ignition system for signs of damp or loose connections.-------
I suggest get the car scanned at autozone service center.Its absolutely free to get car scanned.This will show the problem if you receive the error code.--------
Thanks.Helpmech.

If you drive your car more likely for short distances then engine will not get hot enough to start the regenerating process to clean the cloged particulate filter resulting in a antipollution fault.
Drive your car to a motorway or empty dual carriage way (best in nights). The temperature meter should be showing above 60°C when you begin with this process. Place 3rd gear and drive your car at 3000-3500 rev /min for 15 to 20 minutes to let the ecu to kick the regeneration process. Keep driving car for 15 minutes in this state will be enough to clean your catalytic converter and your problem will be solved. But if it doesn't then the problem is with your catalytic converter and more probabily you need to change it.

See if you can get the codes read, your model often has a particulate filter and all that entails but not allways on the 2,0 HDi, it seems too much of a coincidence to not be connected.

Those are multiple problems. ABS is antilock brake system. Normally this comes on when you need to replace your brakes. Also replace the engine oil in your car and have your car tuned. The check engine light will more than likely go off. If not then the mechanic will tell you what needs to be done to make it go off. Hope this helps
Hello
When the service engine
soon light (Also called the check engine light or engine management
light) is turned on this is to alert you to the fact that Powertrain
Control Module (computer) has detected a failure somewhere in the
systems it controls you may not feel any difference in the way the
engine runs, this can be the transmission or the engine or emission
system, there are fault codes set in the modules memory for these
faults. What needs to happen now is to have the powertrain control
module scanned with a special tool called an OBD2 electronic engine
control scanner or a OBD2 code reader. Once the code(s) are read then
you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.
