Re: [diesel_mercedes] Turbo not performing

 

The shafts in the turbos can get gummed up and will seize if the car was driven in such a way that it never really gets spooled up.  Nates TurboCoupe had this malady when he bought it.  Typical little-old-lady car.  I think he got his freed up by pouring a solvent through the turbo's oil lines, and working the compressor wheel by hand.  You won't have this problem, being as it's just been rebuilt.  (But it's a good lesson to all turbo owners to occasionally do an "Italian tune-up" and run these cars hard to get the turbo spooled up and the oil in them circulating.)

You can confirm the turbo is spinning by removing the large, U-shaped hose between the air filter and the turbo, and observing that the compressor wheel is spinning.  It will spin even at idle.  Under NO circumstance should you even attempt to touch the spinning wheel, unless you don't like your fingers.

Bogy did some good "out of the box" thinking.  Sure sounds like a bad torque convertor.  Normally, I would think it would go out all at once, not off and on.  And the problem would not be noticeable at highway speeds.  But, I'll be the last to say that I've seen it all....

The ATF smells fine. I changed it out about 10,000 miles ago. No problems at all. Yes, it does seem to shift fine all the way through the range.

Thanks,

If it smells burned , try changing it and the torque converter ATF too before popping for a new tranny .

Guys,
My '85 300D is vastly underperforming. 0-60 times are 35 seconds. Last year I noticed that it had started acting real doggy off and on. I would be going down the highway and it would just start dogging. Then it would pick back up again. 

So, I took the air cleaner off and it seemed like the turbo was not spinning well at all. So, I took it off and sent it in for a rebuild, thinking it was the problem. I got it back and they did a great job, it looked like a brand new one. Put the turbo back on and no difference. Still doggy. 

Then I took the alda pressure lines apart and cleaned them all up. Still not fixed. 

So, my next step was messing with the alda. It had never been touched. I removed the plastic cover and the screw would not turn. So, I let it soak in Kroil for a week. Then, proceeded to break the screw. 

So, I am still baffled as to why I am not getting boost. Does my alda need replaced? My exhaust system was new 20,000 miles ago, so I can't imagine that it is plugged. 

Any ideas? 

Thanks
Kevin

Re: [diesel_mercedes] Re: electrical not working

 

The problems with both your turn signals and your hazard lights are almost certainly due to dirty contacts in the hazard switch.  And if only one of the windows is not working, then, again, it's most likely the switch.  Located as they are in the console between the seats, they attract dirt and grime like Beverly Hills attracts plastic surgeons.  The good news is that these switches are both old and German, so they can be disassembled, cleaned and lubricated with a good quality spray contact cleaner/lubricant, re-assembled and re-installed.  For the cleaner, I like CAIG's Deoxit, available at many guitar/musician stores, or high end audio/home theatre retailers.  Or use the stuff Radio Shack sells.  Once treated, the switches should last another 30-years or so....

I forgot to mention no hazard either.
I'll take a look at the hazard switch then see if it has a problem.

[diesel_mercedes] '82 240D AC Died

 



Yes , *if* the compressor needs replacing .

I'll give it a go Thursday this week .

Usually we just evacuate and  re charge it every three years or so .

A Sanden up grade would be nice , this poor old thing hasn't any power to spare .

Who was selling the sanden up grade kits ? .

TIA ,

[diesel_mercedes] Re: electrical not working

 



Go back to the fuse box and use a test light to see if both ends of each fuse show current ~ don't waste a moment cleaning old fuses , they're cheap so buy all new copper strip ones from any M-B , BMW , VW or Porsche Shop .

After every fuse is working O.K. then move on .

Additional fuses in InLine holders is usually a cheap fix for melted fuse connections in the original fuse box , test them all carefully BEFORE you touch anything because a poorly connecting fuse will often show current just after you touch it but not for l9ng .

A new to me 84 300D
I've straightened out a few things.
One electrical item was rear brake lights was just a fuse.
I took all the fuses out and lightly filed the ends to get a best connection.

I can't get any power to the turn signals, dash lights, no antenna action, rear passenger window does not activate.

I found two wires with fuses inline that are set aside at the fuse box, I can see they would be add on and I think that would make one the alarm system.

I see the alarm system and a red bulb sticking out of the dash underside cover but no light inside it, just an empty red shell.

I plugged the two wires into fuses but it did not help the turn signals.

I picked up an additional turn switch and cluster but installing them helped nothing.

The only thing I can think is that there is a short in the wiring that has caused this.


Anyone with any ideas? additional fuses to check?

You could have multiple problems.  Only choice is to go back as far as possible to the source.  This is very hard and tedious.    Check power into the flashers.  That is always on.  This will expose a bad flasher or a bad power line.  Lawrence Rhodes
