“Check injection system” warning in diesel Renault cars

If your Renault with a diesel engine throws the warning saying “Check injection system”, this may mean a lot of things including the fuel pump, injectors, tubes, connections, low level of fuel in tank, etc. But in diesel cats it may also mean problems with the DPF regeneration that are very hard to spot, and there are no codes or other hints that would help you with this. In this video, I will tell you more about the problem and focus on the possible ways to solve it. Fortunately, the “Check injection system” warning may be solved without any professional help, in a lot of cases. You will just need some time. But if you fail to fix the problem the way I offer in this video, the vehicle will need proper inspections in a good repair shop since the injection system in modern engines is quite complicated and will require professional tools for inspection and repairs.
