If you can hear the turbo, it's shot, they are very quiet.
Just because the flap moves doesn't mean you have boost, but you do have
one working switchover valve
Gotta agree with Gerry on this one. I love the faint sound of the turbo on
my 83 300d. Maybe my 2.5 straight pipe exhaust has something to do with
it...lol

You and Gerry are talking about a W123 turbo. Larry,
I don't remember hearing a turbo in a W123 being normal either, but
will find out soon. Certainly did not hear one in the W126 with OM617
I test drove.
Volvo is another story, those sound like a police siren a couple
blocks away!

Every w123 I have driven you could hear the turbo. My ears are very
sensitive to high frequencies and mechanical noises in general. I guess I
am actually listening for it every time I drive.

right about the Vac. Server Control Valves I know exactly what I am
dealing with and have found them next to the air filter. I'd prefer to

Hi peter --
My wife is still using the car for work -- she got home late today so I
started troubleshooting late. Anyway - there are 2 vac cnontrol valves
between the air filter housing and the radiator overflow and one more in
front of the air filter housing and behind the headlight on the

I found the 3 Vac CVs - 1 in front of the Air cleaner box and one
behind. Wish we could post photos here...

Maybe there's a place we can post photos so Kaleb doesn't have to

any idea what section of the WSM has the steps to take to test the
system? I'm having trouble finding anything in the WSM or the parts

I'll check there
If one of the Vacuum CVs is damaged will

Thanks Kaleb -
first thing I'll try is hooking up the Vac Pump to the Turbo and see
what happens I was hoping one of the CVs is damaged as that's
fairly common - but a leak in the vac system is also possible - and that
may still prove to be a problem. May as well cover the bases. I
Hi Gang -
Didn't start early doing my trouble shooting - wife worked o'time.
But what I did - hooked a vacuum gauge to the vac hose going to the the
flapper valve above the Turbo - pulled approx 6 at idle and then went
to 10 or more when I revved it up. Then I re-attached the hose to

Just because the flap moves doesn't mean you have boost, but you do
have one working switchover valve anyway.
Check the kickdown cable for proper operation. I don't know if it
works like the one on the 87, but if it does it is all
The flapper above the turbo has nothing to do with the turbo. You need to hook
it up to the waste gate on the turbo if you are trying to manually operate it
to see if you get boost.

re: Drive it like you stole it Yeah, I like that policy, BTDT! At
least I used to - it's hard to drive it like that when it is about the
same speed as my 240D ;-)
I may pull the intake to check and clean it -- I remember cleaning the
main plenum over the glow plugs -- but I'm not sure
Thanks Peter - I really appreciate you taking the tie to help. I like
having something specific to check. A couple of questions, please ... Is
it vacuum operated or electrical? I should be able to test it either
way but just curious... When you say behind the air intake - do you
mean between
The switchover valves are behind the air filter box, under the
fender. On that model, there are three, one for the boost controller,
one for the EGR, and one for the tuning flap in the intake, I
believe. If any have failed, you are in limp mode -- no boost, no
extra fuel, basically a NA
I may take it to the stealer - sounds like it may be beyond me - I could

anything in the WSM so far. I'm trying the parts websites in hopes
of finding one there so I will know what I'm looking for.
You said under the
under the square air cleaner. There are about 9 vacuum pods under there.
As Peter said several that need need to be tested.

Yes. Remove the air filter housing they are right there.

Hi Chris Gang,
Yeah, that kind of dawned on me yesterday I appreciate the
confirmation. i looked around for vacuum hoses or wires that might be
loose. I didn't see anything and the suction gizmo adjacent to the
manifold going to the turbo - i think it's called vacuum control flap
Larry,
when the turbo in my 90 2.5t has stopped spooling- both times it has been
crud in the pipe from the manifold. Happened twice in 8 years-was when I

If there is a vacuum leak anywhere in the vAcuum system you will not have turbo
boost. Hook a line from the vacuum pump directly to the turbo bypassing
everything else, take it for a drive and see what happens. If you have boost
you have a leak somewhere. Also if any part of the eds is not
More likely a blown vacuum servo control valve behind the air intake
box.
