Speed fluctuation at 407 constant speed

When my vehicle travels at a constant speed on a long road, there is a cycle fluctuation, the car goes with it.

I am hearing from you for the first time, hodja. there is a possible cause. air meter - can be the accelerator pedal position sensor and brake sensor. First of all, you have a look at the error codes in a service with the original Peugeot software.

Can you feel this ripple in the engine? If you can't feel it, the display may have trouble

[QUOTE = okan0752] When my car travels on a long road at constant speed, there is a fluctuation of speed. The car goes with it. Does anyone live the same thing in my work. If you can find the fault or the solution, I will follow.

Did you find a solution to the problem?

On my 1.6 hdi comfort 2006 vehicle, I experience cycle fluctuations while traveling at an average speed of around 3000 km at a speed of 130 km. There is no more room for the flowmeter solenoid valve to be put on the brake vacuum pump. I think I found the problem. I had an egr cancellation software 2 months ago. When I inquired for those who knew a little in the industry, I realized that the software was not effective in our pejo. Of course, I asked everybody who is not a single mouth, mechanical mechanic, who is an electoral brainer. Anybody said that it would be. I had 407 in my software, I threw it myself. The errors in my computer are flow meter and solenoid valve. I changed the zeros and tried the same errors again. Let's see if I will remove the software and try it without software. By the way, I'm hungry in the ideas of the idea.
