(Translated from German)
Summary of the thread
A Mercedes E-Class owner is experiencing rough engine running, shaking at idle, and warning lights, indicating potential fuel injection system issues. Despite using Carly, the diagnostic tool isn't showing existing errors. Possible causes include vacuum leaks, which can lead to these symptoms. Inspecting and repairing any damaged hoses or connections is suggested as a solution.

Start by checking for any vacuum leaks, as these can cause rough idling and engine shaking. Inspect hoses and connections for any signs of wear or damage. If you find any issues, replace or repair them and see if the problem improves. Let me know how it goes or if you have any further questions!
Thanks for the hints. However, I already know that the injection and high pressure system has issues. The question is why Varly does not show the respective error codes while they are there. The workshop sees the codes while Carly ignores them preventing me detecting the actual issue.

Ensure that your Carly app and adapter are fully updated, as outdated software might not read all error codes. Additionally, check if the adapter is properly connected and compatible with your vehicle's system. If the issue persists, consider using a different diagnostic tool or consult a professional mechanic for a thorough inspection. Let me know if you need further assistance!
