Its a new egr valve no handy to diagnostics but there is no fault codes
UK Auto Mechanic: Rob, UK Car Mechanic replied 4 years ago

Hi

most diagnostics have a feature called live data and reading the voltage and signals from sensors can often find where the fault is even without a fault code.

Hi, I’m a Moderator for this topic. It seems the professional has left this conversation. This happens occasionally, and it's usually because the professional thinks that someone else might be a better match for your question. I've been working hard to find a new professional to assist you right away, but sometimes finding the right professional can take a little longer than expected.

I wonder whether you're okay with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, please let me know and I will cancel this question for you. Thank you!

Hi there, Here is the procedure to adjust the injectors: The correct method is to use a dial indicator mounted onto the rocker, then rotate the engine until the full depth of the stroke is reached. Screw in the adjuster screw until it bottoms out. Then back it out 180 degrees. Tighten the ball screw lock nut to 24 ft lbs. VW did standardize the setting for all PD motors for a 180 degree setting. The problem is, there is no decent place to attach a dial indicator's bolt-on or magnetic mount. The following pictures show how to do the operation with no dial indicator. This is the position of the cam with the #4 injector rocker fully depressed, side and top view:

 

 

 

Please let me know if this what you were looking for. Cheers.
