    Do diesels have throttle bodies? :

    I thought all diesels increased and decreased through variations in fuel injection, not throttle.


    I know that CDTi 150's have swirl valves, but this would be the nearest to a throttle on a diesel!!

    If there was a throttle body there (dunno) it would be under the plenum bit, right after the black silicone hose that comes from the intercooler (bottom right).

    intercooler - silicone hose - plenum - throttlebody - inlet manifold

    Im 100 % sure their is some kind of throttle body but it may have a different function on a diesel (not sure).

    Have a look at this pic, the TB should be under the bolted on metal pipe which is circled in the picture. You need to remove it first.

    However, I am not sure if the diesel has a TB, I drive a petrol 2.0t. Someone will know better I'm sure.

    My nick is latin for "cause of death", stupid I know..

    This is the throttle body for a Y22DTR, is the item circled in yellow in the previous post.

    The red bit with the question mark is the oil filter..
