UK: 2010 Audi A5 (Diesel) - Wont start after Fuel Pump Pressure Regulator replacement
 

My car was extremely low on fuel. After a short stop then start, I noticed the car was shaking at idle. I needed to fill up in which I did. Car was still shaking. I bought a cheap scan tool off Amazon and got code 05175. The web said to replace something called "Fuel Pump Pressure Regulator". See red circle in image; only held by two screws.

I replaced the old with new. Car started for few seconds then shuts off. I tried starting but it never seems to start. Switched back to old, can wont start. I head I need to "bleed" or remove trapped air. How to do this? Do I need the VCDS scan tool as in ?

Have you managed to start it? What did you do?I am having the same problem after running without fuel because of second fuel pump disconnection.

No, sorry. I wasnt in the country so it was left at home for 4 months. It's now in the garage for 2 weeks and they cannot find the issue 🤔So far they have replaced 3 fuel injectors that were leaking but car still wont start. Once fixed. I'll update.

Hi Speedy Did you manage to get the problem fixed? any update of what was wrong ? having the same issue.

I have the same problem
