Manifold fault with VCDS report

[Jimmy2007]

Hi everyone,
My A6 C6 4F 3.0l quattro TDI has been randomly lighting the engine management light and becoming more and more persistent.
Car drives just fine, but I had it scanned and these are the results:

012597 - Intake Manifold Runner Control
P3135 - 001 - Lower Stop not Reached
Freeze Frame:
Fault Status: 01100001
Fault Priority: 0
Fault Frequency: 48
Reset counter: 255
Mileage: 106878 km
Time Indication: 0
Date: 2022.06.03
Time: 18:00:37

Freeze Frame:
RPM: 756 /min
Torque: 62.4 Nm
Speed: 0.0 km/h
Voltage: 13.98 V
Duty Cycle: 88.8 %
Duty Cycle: 80.9 %
Duty Cycle: 80.9 %

I searched for this and found that it's a common problem.
Anyone willing to advise on a solution?
I understand that there's a repair kit for the manifold, anyone here who's done this before willing to help?
I'm in west London but can travel a reasonable distance.
Thanks

Depends if it's the intake rods, possibly something I could repair for you, need to check if it's this or another issue 1st.

How would I know?
From the scan it seems to be the intake rods, a common problem on these engines.
Where about are you?

I think I've sorted it.
The intake manifold rod was disconnected at the bottom.
I reconnected it and the engine management light disappeared.
I let you know if it happens again.
I wonder how it came off because it took quite some force to push it back into the small retaining ball.
I wonder if those cowboys at Audi have something to do with it because after they changed the air filter (courtesy service after an accident) they "forgot to close the jubilee clips on the big intake hose just in the same spot.
