Hi. Going up to Skye next week to my sons. As uaual there are items require for car. One is slight hesitation with above fault code. switch for tensioning strut. Stowed. F204. Anyone got an idea to give me a head start. I know they have manifold issues but I replaced this under a year ago.
Thanks for reading

Adding a 0 to your code = 001089

Which on Ross-Tech comes up with:

16825/P0441/001089 - EVAP Emission Control Sys: Incorrect Flow

Possible Symptoms
Malfunction Indicator Light (MIL) active
Possible Causes
Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80) faulty/jammed
Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115) faulty/jammed
Evaporative Emission (EVAP) Canister Sealing faulty
Pipes between Tank Breathing and Throttle Body leaky/blocked
Possible Solutions
Check Evaporative Emission (EVAP) Canister Purge Regulator Valve (N80)
Perform Output Test
Check Evaporative Emission (EVAP) Canister Purge Solenoid Valve (N115)
Check Evaporative Emission (EVAP) Canister
Perform Basic Setting
Check Pipes between Tank Breathing and Throttle Body
Special Notes
When found in the NAR 1.8T Audi A4 1.8T check TSB 24-08-78 or 2010268/3 or Pass-Thru equivalent TSB
When found in the NAR 1.8T VW Passat 1.8T check TSB 01-09-09 or 2005554 or Pass-Thru equivalent TSB
Note: The Passat 26E5 or "R5" recall includes the same software update
Make sure the quick release lines for the N80 valve and vacuum line to LDP are not crossed.
This can also make the engine hard to start after filling up the fuel tank.

Sorry for late reply.. miss from cold for a few seconds. Suspect sticking valves. Gave top half a forties gas treatment through sensor in manifold.my son reported back a month later to say that running well. He is going to do the same every so often.i replaced the manifold a year ago and cleaned the valves then but shows you how quick the grunge up.
