Must be some bad information getting to the ecu. Bad conections due to salt corrosion may be the cause. Bright metal contacts are essential for correct transmission of information from sensors to and from the ECU (brain).
yes you probably have EGR not working and this as may filled your particle filter ,you can use a trick if your side mirror is warm this means that you have a regeneration going
Check egr valve system, check turbo boost solenoid, is it hot ? It should be war but not hot. Check turbo waste gate. Remove the black assy that hold the butterfly valves inside that the turbo air hoses connect onto to and make sure they work by sucking on the tubes to activate them, they are sring opened or closed and the engine vacuum system opens or closes them.
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
I am not familiar with the 407 but I would think it is a HDi, if so what you describe is an air leak from a pipe from the pressure side of the turbo, I have had this on a Saab, in that case there was an over pressure switch under the dash and the pipe fell off. Look at the top of the engine, on the inlet side there will be a pipe from the inlet trunking or manifold, it should (maybe with a tee piece in there) go through the bulkhead
