    My lcr has been running rough when cold so I checked the fault code with vag-com and it came back with 19534/P3078/012408 - Throttle Control: Airflow at Idle too Low.
    Ross-tech'swebsite said possible causes are solutions - Clean Throttle Body, Perform Throttle Body Alignment (TBA). Check for Intake Leaks, including PCV system and Evap (N80) solenoid
    Any ideas whats the most likely cause out of the two? Where is the n80 solenoid?
    Would anything else cause the same fault code? Maybe a maf problem?

    I had the same fault mate, and it was a split pipe under the inlet, I then ditched all the OE PCV system and did the catch tank / breather

    Was the pipe easy to find? Is it an easy enough job to fit a catch tank?

    to be honest mate I had soo many air leaks it was hard to pin point it so I just ripped it all out and did the catch tank, it is an easyish job to do, most fiddly bit is removing all the under inlet stuff, but it should still not take you more than say 1.5 hours to do

    Sounds it might be worth doing then. Is there a guide anywhere showing how to do it?

    Check the FAQ section for PCV delete, it contains a lot of pics. You only need to check the PCV system
