Audi A5: Particle filter and emergency running problem
(Translated from German)
Summary of the thread
A 2009 Audi A5 owner is experiencing issues with a clogged particulate filter and the car entering limp mode, despite regular highway driving. The problem might be linked to a faulty glow plug, as a similar issue occurred previously. Suggested solutions include performing a forced regeneration of the particulate filter by driving at higher RPMs and inspecting the glow plugs and EGR system for faults.

It's possible that a faulty glow plug could be contributing to the issue, but since the particulate filter is involved, it's important to address that first. Try performing a forced regeneration of the particulate filter by driving at higher RPMs on the highway for about 20-30 minutes. This can help burn off the soot accumulation. If the problem persists, it might be necessary to inspect the glow plugs and the exhaust gas recirculation (EGR) system for any faults. Let me know how it goes or if you have any further questions!
Okay, tomorrow the ADAC is coming and we'll try to manually start the free-running mode. If that doesn't help, I'll take the vehicle to my friend's workshop and have the glow plugs replaced. Thanks for the information👍

If the manual regeneration doesn't resolve the issue, make sure to also check the differential pressure sensor and the hoses connected to it, as they can affect the particulate filter's performance. Keep us updated on your progress, and feel free to ask if you have any more questions!
