Mismatched leak off from injectors on 2015 Audi TT TDi.

[MitchC]

Please stop looking at the deviation figure. I has little context to anyone but you stood next to the car with Actual and Desired displayed.

Can we please work with and post just the Actual Rail Pressure measurement. Most of us know what the rail pressures should be !

To be honest, it had no context to me either, even though I’m here.

If you know what the rail pressures should be, would you care to tell me please?

Your ECU can tell you.

IDE02228 -- Fuel pressure regulator valve: specified value rail pressure (hPa)

This value will fluctuate depending on operating conditions.

There is no "IF"

I do know !!

Then stop playing games and post up useful information rather than playing "hide the potato" with snide comments and singular requests.

I see you only quoted half of my post and decided to ignore the rest.

It is not about playing games I just asked you to post up Fuel Pressures so I could comment on them to assist you.

I asked a question and expected an answer, not a question in return !

Now you ask, in an ideal car Hp should hit ~ >300 bar within 2 turns of the engine.

 

[Dr Sheldon]

Can you Graph, in VCDS, Fuel Pressure and RPM showing 5 seconds of cranking.

Before you go ranting on at me, I never even posted the comment, though I do agree with the sentiment.

I can’t graph in VCDS, and I’m not being awkward in this case-I’ve tried but not succeeded. I did post up the log and Excel.

Moot point now anyway, as I changed the injectors and it now runs but still brings up a low rail pressure fault. I’ll get the newer logs posted up when I finish this beer and get my fat ass out of the hot tub.

Clearly not a Moot Point then !

It is not ranting - I do have an award winning brain !!

Shut up

I asked a valid question.

No, you bragged without being helpful. Your subsequent response in which you provided an actual value was helpful, your initial response that I quoted wasn't.

Of course it is, they’ll be different now.

Out of interest, what award did your brain win?

Don’t know how to save a graph yet.

This is the car while driving. It throws up the low pressure fault when pulling away and loading the engine.

That looks a bit like a sluggish pressure regulator, but I don't know enough about the TDI's to be sure.

 

[MitchC]

It has a new Bosch one. I’m going to put a new sensor on too, but that won’t be here til Monday at the earliest.

 

[davisev5225]

Bosch, or "Bosch"? Where'd you acquire it from?

Keep going - It will help

The bay. From your post I guess there are a ton of fakes.
