TDI Engine Carbon Buildup (Pictures)

[Luey]

Hey everyone,

I've had the day off so today I'm replacing my plastic inlet manifold with a alloy inlet manifold, removing my swirl flaps, blanking off my egr and cleaning out the oily carbon deposits from this side of the system. I'm still putting everything back together but I thought you might get a kick out of the pictures!

The last picture is my EGR valve at 114,000 miles, I will take some pictures from inside the manifold shortly.

The moral of my story, if you love your car, either blank the EGR or clean your intake system!

Wow! I dread to think what my Diesel engine looks like on the inside lol

take the air pipe off your EGR valve and have a look. if it's bad remove your inlet manifold and clean it, return it then blank your EGR

Surely mine is too old for an egr?! It's the 2.5tdi engine from 2002

deffo not too old, but i can;t confirm whether your engine has one or not. they've been around for years though

[rbdazza]

just googled it, your car has got one, i bet its cloggy as !Removed! in there, have a look and blank it

I didn mine last year. It wasnt that bad after 11 years but it always helps when intake is clean.
