I need help. I have a 2002 A4 and after a 5 minute drive the manifold and a little part of the cat glows.

were you stepping on it? It happens if you drive the hell out of it

if you are doing that, you won't only see a glowing turbo, but you'll be spitting turbine blades out of your exhaust!

other than that...I wish I could explain that. Are you at high altitude, or climbing hills right off the bat? The turbo will work harder in those conditions.

normal

even if i drive normal, it heats up. I didnt do any WOT but I drove it kinda hard. should this be normal?

DenverNoob

Are you noticing it in complete darkess, or outside in the sunlight with the hood up. In the dark, I woldn't be suprised. But if you can really notice it in daylight, i might be inclined to think twice. I'm running high boost and big injectors and don't notice that during daylight after normal driving.

A4 Moda

maybe you should drive hard after your temp. goes up. but otherwise, should be normal.

Not overstressing it, then perhaps it is not normal. You also mention that the cat is red and glowing too? Now that does not sound normal. Do you feel a loss of power? Does the car perform normally?
If not perhaps there is a problem. The cat glowing as me thinking that perhaps it is starting to get blocked. Maybe a visit to a tech is in order.

the engine is still cold? I thought I read that somewhere before...

I notice it in the dark. The performance seems normal, I just don't understand the glowing, does anybody else have this? It is acually glowing at the manifold and right in front of the turbo.
