Edge Diesel Intake Manifold Issue

That sounds familiar. I had a similar issue with my old Audi A4. The symptoms you're describing – the jerking, check engine light, rough idle, and power loss – point towards a potential intake manifold problem. Do you notice if the engine runs even rougher when it's cold? Also, does the stored error code mention anything about engine misfires or manifold pressure?

Yes, it definitely runs rougher when it's cold. And now that you mention it, the error code did have something to do with manifold pressure. What exactly was the problem with your Audi?

Okay, the rough running when cold and the manifold pressure error code make the intake manifold issue even more likely. In my case, the intake manifold was leaking due to heat causing scorching around the gaskets. Think of it like a leaky pipe; it throws off the whole system. The garage confirmed it needed replacing. I'd recommend getting it checked by a professional workshop. The bill will be around 1200€.

Thanks for the advice. I took it to the workshop, and you were right – the intake manifold was defective. The repair cost me 1180€. Appreciate the help!
