How can you tell if turbo is working?????
 

i was looking at a forum and i saw somone's turbo wasnt working. How can you tell, well i know for my 85 300d cause i can hear it but i have no clue for my 83.

A non working turbo makes the car accelerate slower than a garden slug. Of course, stuck open waste gate or if the ALDA is not getting boost signal will make it accelerate the same way.

at about 2KRPM, the motor should start to pull hard, if it does not. you have no boost.
a boost pressure gauge would assist in checking out the turbo too.

Mercedes turbo engines installed on 126 and 123 cars have a connection to driver's neck, when that turbo kicks in you will feel it in your neck.

Or, if you have a neckbrace on and you can't feel the turbo, you could put a pressure gauge (mityvac should work) on a t after the alda (between where the vacuum hose comes out the intake and to the alda - at least it does on the 92 300D) and then see what pressure is going to the intake. Should be around 10psi at around 4000rpm I believe (on a 92 300D).

Don't take my word for it though, I'm not an expert (yet)

pdrayton, I live in Fernandina as well. Was that you I saw in a 300D down sr107 and waved to Wed or Thur? I have a grayish/blackish 85' 300D.

Update your CP accordingly.

It's a 240D but thanks for the compliment! :)

Yes, we've met haven't we - you gave me that 275 gal tote.

How you doing? How much oil did you get at Shrimp Fest.? We need to team up for the next event I told you about.

He means your signature in the User CP (control panel section) with what car(s) you have.

Bill, I'll pm you.

But I do not understand the statement. I have nothing to update. ??????

I believe he was indicating the need to update your location. You have nothing listed for "location".

Done. Thank you for the info.
