My name is ***** ***** I will try to assist you.

Per my info, the code 35 has to do with the exhaust temps sensor. This could be due to the overfueling.

Usually when you get overfueling on a diesel injector, the injector is bad. The tip could be blown off, the intrnal valve isn;t closing all the way, or the solenoid isn't responding.

I suggest pulling the injectors and having them tested to see which one is bad. There is a test called a pop test that will check to see that hte valve is working properly inside the injector and it will measure the spray pattern off the injector to make sure the injector tip isn't damaged.

not the website. I have no control over the site fees, site errors, category errors, or how long it took for a response for these reasons.

I am not an employee of this website, so please rate with a POSITIVE (green) rating for me to get credit for assisting you. You still pay

I do have many workshop manuals, diagrams, etc that I pay to get access to out of my pocket. If one is needed, please ask and I will give
you an offer at my technician discounted cost to you for such manuals. I never charge above that cost.
