Question

206 HDi engine stalls/dies momentarily on the move

Sep 26, 2017 5:03AM PDT

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?

My view on the OBD code
Sep 26, 2017 10:00AM PDT

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.

Another OBD signal found: P0335 (Crank shaft sensor)

Hello, and thanks for the answer. Both as an answer to your post and as an update, today I have made a visit to the local Bosch Diesel service, and to my surprise, their diagnosis device spotted a signal which others could not, and it is P0335 (Crank shaft sensor). It looks as a more probable cause to my problem, what do you say?

I would be repeating what I wrote above.

I've found fixing what causes OBD errors to usually fix a lot of issues. But that's only partly why I do this. Here there's a rule about passing smog checks and that is a clean OBD reading. So even if you ignored the OBD your car would be denied renewal if you didn't clear those codes. This means you are stuck fixing it unless you are planning to dump the car.

And yes to probably direct cause to the failure. HOWEVER I would never blame the other person or shop for missing this one. Some of these are intermittent and it's the luck of the moment if the issue happens when the OBD is hooked up. As well as some shops have different OBD readers.

Yes, I own 2 OBD readers. Neat, cheap stuff now. One was an under 30 buck all in one and the other is the 10 to 20 USD model which you use a smart phone over bluetooth and an app.

Why? Just because I like to have a heads up on what the dealer may tell me.
