Is to correct that first. It's a known thing so we correct that first before we guess what else it is. However you will encounter folk that want assurance this will fix it. Sadly, I've yet to find any mechanic nail it everytime. So my work which sometimes involves cars (our office works on apps) is why I've learned to always get a clean OBD before we go guessing what else.
Long story short, I am posting the video of my problem here:
(It is a 2005 Peugeot 206 1.4 HDi on 214k kms)
The car has been doing this for over a year now. Sometimes it is all fine for months, sometime the problem gets more severe. Few weeks ago, for the first time, the engine stopped on the move and did not start again for few minutes.
The only OBD code I read is about the air flow sensor. But I am not sure if that is the problem. Some mechanics say this is electrical-related, some say diesel pressure sensor.
The prices they talk are really high and I doubt giving it away when the problem is not properly diagnosed. Any ideas on this problem?
