    Is it normal for a Volkswagen 1.8t turbocharger to be glowing orange on the exhaust side after driving on the highway for ~20mins? I know the turbo has probably the shittiest job in the whole car, but still, that seems really hot. How does it not burn the engine oil that lubricates it at that temperature?

    Is the car stock or are you running a chip?

    It's a stock Passat, no mods at all. I guess the RPMs were around 3000 or so, about 80mph on that car. Not a lot of hard acceleration, just a good, steady 20 minute commute home. It's worth noting that only the exhaust side was glowing; the intake side looked normal.

    I didn't leave the car on to cool the turbo down because I didn't notice it until I'd turned the car off and gotten out. I was originally going to check the oil. I didn't hear any spinning sounds coming from the turbo, so I assumed it had already stopped by the time I noticed it.

    Why don't stock cars come with turbo cooldown timers anyway? And how do I install one?

    It sounds like you might have a clogged cat.

    Hmm. That's not something I'm familiar with. What makes you think the cat could be clogged? What's the logic there? I'm always up for learning something new.

    I didn't think the cat had enough catalyst inside it that it could get clogged just with oil smoke or whatever else the engine might cough out. Is there any way to test for that without taking the cat off the car?

    turbos run off heat so they should get pretty hot.

    He's right, in a way. Turbos are powered by the rapid expansion of exhaust gas -- expansion that would not happen were the exhaust gas not hot.

    At night you should notice a glow after a long drive, even if not a hard one. When I used to go up a long hill at night then stop and look at my turbo it and the manifold were a really nice orange. If its a slight glow, nothing to worry about, if the whole things bright orange after a normal drive, maybe...

    Check a friend's?? Maybe the car is running lean (hotter EGT).

    If the car is no laggier than normal, or not requiring more accellerator than normal i wouldnt worry about it. Always use a good synthetic oil to prevent coking, dont skimp.

    First off, I use Mobil 1 at all times. Even in my lawnmower.

    Yeah, I noticed the glow at night. So I guess it's normal, I'm cool then. I was afraid I had a bearing that was about to seize. Just what I'd need after spending $1000 to replace the engine computer and oil seals -- spending another $1000 to replace a blown turbo.

    Thanks for all the feedback guys, I guess this topic's closed.

    yeah if youre worried, buy an EGT gauge and see if your temps are waht they shoudl be

    but it's not unusual to get red on the exh manifold and turbine

    Actually, I'd like to get a boost gauge, a Fuel/Air gauge, and an EGT gauge, but I can't find any decent gauge pods that mount on the A-pillar of a B5 Passat.

    Actually, I can't find ANY gauge pods that mount there. I really really don't want to put pods on the dashboard.

    i'm sure they exist.....otherwise you can put them in the center console or a custom enclosure/pod on center section

    And dont waste your money on an A/F guage, they are just blinkey lights and will do u no good. The EGT gauge will get u what u need to know. Otherwise, if you get one, get the Jumptronix unit

    glowing turbos are normal. try lighting a cigarette with it then you know you're cool. Most if not all of the new cars already have a turbo cooling system its just not your old style leave your car idling method either. You can usually here it in volvos after hard runs when the car is off. it sounds like an electric fan.
