Believe me you wont miss the pre 87 tractors a bit although i do have a 617 soft spot. These things are quick. A whole different animal. And the handling is a world apart. If your feeling ambitious Davey at Potomac German auto gets a E500 from time to time and most of the cool suspension bits drop right in. Grab a thermometer your A/C shouldn't have trouble doing 40*-45* at 90* on a highway cruise although the evap could probably use a cleaning, gotta love R-12.

Looks like someone removed the headlight wipers - very odd. Those would have been part of the cold-weather package (ASD & heated seats).

Can you post a photo of the CD player? Doesn't sound factory to me. A scan or photo of the window sticker would be cool also.

The car will be about as quick as a W123 300D turbo sedan. Factory spec is right around 13 seconds for both the 124.128 and also the 123.133... the W123 weighs 100 lbs more, has nearly identical HP rating, but an extra 20 lb-ft due to the larger displacement. Ends up being a wash. You'll need to check via stopwatch to find out if the power is normal or not.

I haven't made a post on here in a long time, but this car is worth a post. I love the red leather and the 2.5 engine. The 602 does not have the head cracking issues of the 603 and by 91 it had the new casting anyway. It is a great econowagen in awesome shape for a fantastic price. I am with Dave - send more photos, especially of the interior/stereo. Enjoy your new ride.

The wastegate could also be as simple as the arm from the vacuum actuator having come loose from the wastegate. The arm is held on with a circlip and it may have popped off.

Here is the window sticker.

and a picture of the stereo...sorry iphone 4 camera at night...Actually ran out to the car to snap it. Thanks Yall...So much helpful info..pretty interesting car huh

I said earlier the only cars I were familiar with were 85 and older...I had to double check my signature to remember the POS 87 300dt I had. I had forgotten about it. I only owned it for a few weeks because it was a basketcase but man it would fly! I forgot about that. Not one thing worked on that car electrically but it started and ran and shifted great...No wipers and all! lol That thing poured oil, tranny fluid, and diesel...I paid $3000 for it and a mint 1981 Lincoln Mark IV...Sold the Lincoln for 2750 and I think I still managed to get 2200 for the 300d back in 2007..Guy called me 2 days later and said "hey this thing quit running" I was like "No s*%$ !

Cool! That appears to be the Audio 10 head unit. Click here for the owner's manual in PDF format. I don't believe that was factory equipment, not even special order, back in 1991. It's an MF2910, I think made by Alpine, not Becker. Most likely it was an upgrade by a previous owner. It is not plug & play with 1991-1993 models. The connectors on the rear are totally different. Someone had to do creative re-wiring to make that head unit work.

The "high performance sound system" on the window sticker was an upgrade to the standard stereo system. This likely includes upgraded rear speakers with dual, angled tweeters and possibly a few other upgraded components. But it didn't come with the in-dash CD player.

This Audio 10 was offered in Europe from 2000-2002.

I retrofitted it in my E430, and it was plug and play.

I have no idea how they made it work in a W124.

It is not a 10 disk changer by the way.

If removing the ALDA restored power to expected levels, you could have gotten away with cleaning the ALDA signal line. On these cars in which EDS controls the wastegate with a vacuum signal, the more typical cause of low power is a fault in the emission control system which removing the ALDA won't mask. I'd still explore a pressure wastegate conversion, but, hey, I'll choose your situation any day

I wonder if your car might already have a pressure wastegate. Temporarily disconnect and cap the signal line to the wastegate actuator and see if it feels like a 240D again. Don't push too hard or too long, just enough to confirm one way or the other.

GSXR, are headlight wipers a window sticker line item? Are 'reinforced springs' different corner foam pieces or a different spring unit altogether?

Normally, the headlight wipers were part of an equipment package. However, it's possible this car was custom ordered without them. Since each item is separate on the sticker, with no mention of a package, it might have come from the factory without the wipers. (I think the wiring is all present and it would be easy to retrofit, if desired, but I'm not positive.)

The reinforced springs are stiffer metal springs in the seat frame, AFAIK.

I wouldn't leave the ALDA removed, IMO this is a band-aid for other problems, but I've given up beating that dead horse.

rather be safe than sorry. I will back it off some and reinstall. Then investigate the actuator conversion. Got to get a gauge to check the boost first.

joegolden · #12 08-21-2013, 07:33 PM

I wonder what this is all about? Am I missing something? Looks like a lil wire job there.

Looks like someone removed the factory 30A strip fuse holder for the HVAC blower, and replaced it with an aftermarket fuse setup. I'd convert it back to stock...

sixto · #14 08-21-2013, 08:29 PM

What does the wire attach to at the ends?

Shouldn't there be a 30 amp strip fuse in a solo plastic box on that body color ear hanging from the strut tower?

I'm more concerned about the color of the brake fluid than some random wire. Get that coffee out of there!
