Intake manifold
« on: 31 July 2025, 15:43 »
Second manifold to replace!! First replacement was an updated version after 4 years so suppose this one has lasted better after a further 11 years. Might leave it for a bit as don't do many miles

Same fault code and engine management light. Not had a chance to check yet but likely that flaps are not moving correctly. Is not affecting driving at the moment. Surprised if it is carbon build up as have been using 99 Octane for last 12 years.

Reset the fault using VCDS and now driven nearly 100 miles with no recurrence. Maybe just a blip :huh:

Depends what milage done on that time I suspect. Maybe starting ro get coaked up restricting movement slightly at the moment. If happens again maybe remove and clean.

Mine did this years ago RAC reset it came back after a few weeks as flap sticking on the in let manifold.

New manifold fitted under extended vw warranty was fine then.

It will definitely go again unfortunately.

Revisiting this thread. Took manifold off and cleaned which seemed to work as carbon build up. Lasted for about 3 months then fault back so have now replaced it. What a pain to keep removing and then got a misfire and smoke after new  manifold installed!! Tested spark plug and coil but it eventually found I must have damaged an Injector on cylinder 4 so removed again. Finally all fixed. May be time to sell?
