I have a 2003 peugeot 406 saloon hdi 90bhp I want to fit a towbar and have to work out if I need a bypass relay so does my car have multiplex wiring or canbus system or bulb failure system

No those plugs are stricktly for double towing with a tow bar only, you will have to install a second single tow plug.

SOURCE: injectors

Injectors from the same ccm engine are most probably sounds same but to be on the safe side check not only the shape but code on the top of injector too. Because they are piezo effect injectors and set by the manufacture for a specific pressure for specific engine codes.

Its a dpf not a cat.Easy way to clean out[regenerate]First bring the engine to normal temp bring up the rpm to 4000 for 2 mins,then allow to idle for 30 seconds then bring the rpm up to 3000 rpm for 3 mins and yourfilter will have regenerated [fancy word for clean itself out. DPF = diesel particulate filter.Its important to use good quality low ash oil for your oil changes.
