Ive got a 1.6 FSI which isn't running correctly. I bought it with a misfire / bad running thinking i could get it running right and save it from the scrap heap.
First thing i found was a split EGR pipe, i fitted blanking plates as i didn't have any brazing rods to weld it up. The car ran much better but still at low revs it misfired and spluttered.
The fault codes i had were 16788 EGR system range / performance P0404
17439 Intake manifold tuning valve (N316) set point not reached P1031
Looking at the inlet manifold / fuel rail i could see the plastic arm had snapped so i knew i was going to have to remove it!!!
Ive changed the sparkplugs / serviced the car (fuel and air filter) still no different.
I removed the inlet manifold and injectors, gave it all a good clean. I watched a You Tube video showing how to clean the injectors so cleaned them and it appeared to work, they showed a good spray pattern. I repaired the arm and refitted everything.
I started the car and it was still the same from low revs. I held the revs at 3-4k for about 30 seconds to see if it cleared, i went to look under the bonnet and noticed the catalytic converter was glowing red hot. Now has anybody else experienced this?
Researching why it was glowing red hot appeared to point at to much fuel going into the exhaust because of misfires. A blocked catalytic converter was another possibility.
Ive had the engine running for a bit and its showing no fault codes!!!
Has anyone had this problem or got any ideas what wrong?
