Coming on here because I am out of ideas, I have an 2.0tdi 2009 (140) and it has a glow plug light that comes on as soon as the car is started and stays on and sometimes an engine light and the code is p2563. I changed the turbo actuator,the egr, n75. Didn’t work so I took it to a specialist and they tested the turbo and actuator and was working fine and boosting. They then said it was the egr intercooler which I got changed and the lights are still on the dash. When you clear the code it comes back on a few seconds after the engine is started and the engine makes a slightly different noise when the coil light re appears. I just can’t seem to get any answers or solutions so was just seeing if anyone has had the same issue and fixed it…

Read a similar error, that was eventually traced to a vacuum leak off the EGR cooler. I think at the very least you are going to need VCDS and then measuring blocks which basically gives you live data. The fault code is one thing, but you need to understand why, and live data should help pinpoint.

This was on 2010 model. https://www.audi-sport.net/xf/threads/378244/

Please do. In the meantime I shall release your other query that I hid pending a reply here.

UPDATE

so turns out the aftermarket actuator I put on it was either faulty or not set up properly, I changed it back to the original faulty one and got the original po299 code back and got a genuine actuator fitted and fixed the issue.

Glad you got sorted 🙂
