Catalytic Converter Warning Light

**jdw** · 26-06-2018, 01:11 PM

Hi, I have a 2012 118 tsi Golf Hatch. Twice in the last 2 days the Catalytic Converter warning light has come on for a while then gone off. This was also accompanied by an intermittent loss of power. I fear the worse, does anyone have experience with this warning light and its ramifications !

Only way to find out is to have it scanned, and go from there.

SO the initial diagnosis from the local garage is it : "requires the intake manifold to be removed for inspection and manual cleaning of the valves" they recommend " regular cleaning of the the induction system to reduce carbon build up on the valves and induction ports" .

Does anyone have thi done to their car "regular cleaning of the the induction system........"

Fairly typical for direct injection engines these days.

As far as regular cleaning goes, a can of intake cleaner such as that from Liqui-Moly through the system every service will keep the carbon build-up to a minimum.

That seems to be a fairly easy and mandatory thing to do ...I wonder why it wasnt done at my last service!
