I think its not so much the engine as it is the cars that the engine is put into - S/CL/SL are all obscenely complicated pieces of machinery and there are a million other things to go wrong before even addressing the engine.

The merc v12s are way better than bmws, no doubt. The m73 is actually a good, if lacklustre, engine. It's an improvement over the m70 anyway. Neither have a lot of tuning potential, but who really does much to a german v12 anyway?

I'd say the merc V8s of any vintage are my vote for most reliable engine in a mercedes. Maybe the v12 is more reliable overall, but it'd cost way more to keep it running.

If you have the patience and some good diagnostics, I would wager that most of these problems (minus the air suspension and ABC poo poo) would be fixed by reflowing solder and cleaning connections.

Beyond that - ABC would be an utter oval office to fix. I imagine they will make a regular coil conversion as time goes on.

I really want a CLS55. Are these part of that "low build quality era" or are they generally pretty solid?

I always was in love with the car, and poo poo now that I can afford one, been strongly considering it. I need me a german muscle car in my life with wild style.

That's how I felt when I bought my E55. I had always wanted one when they came out, and 6 years later the perfect one popped up for sale and I grabbed it. Very expensive things can go wrong, but I was lucky and was able to fix the few issues that popped up on mine over the 70,000 miles that I owned it. The drivetrain is basically bulletproof, and doing rolling burnouts in a Mercedes is always good for a laugh. I think the CLS was another 300-400 pounds heavier than the E-class, but when you're talking 2 tons plus it doesn't really matter. The supercharged 55's will definitely teach you that gobs of torque off idle is way more fun than something like an M3 or M5 with a more peaky powerband.

I am going to go look at a 1984 W201 190D (with a 5 speed) this weekend; this isn't my first rodeo (1x W110 and 4x W123, all diesel) but is there anything special about the W201 that I need to consider?

edit: fair enough, based on the response, I guess there isn't anything special to know

edit 2: So, now I have a 1984 W201 190D to complement my:
1967 W110 200D stick with a hole in the floor
1977 W123 300D stick that is my daily driver
1977 W123 300D with an auto that needs replacing
1979 W123 240D that is about to go to out to pasture
1985 W123 300D with a poor front suspension

Now I just need a W115 and I have a sequential set .... and then a W120 to complete the set.

Well after 3 years of ownership my 2004 E55 is starting to sag intermittently on the rear driver's side. Diagnosing it is a pain but odds are its the rear air springs. I suppose 10 years and 85,000 miles is a respectable life for the parts though. Ordered some new Arnott replacements for less than $700 shipped, hopefully this takes care of it and I don't have to chase gremlins.

Bought a facelifted W220 S 320 CDI. It was previously owned by an elderly gentleman who passed away and his son debadged it and put AMG tailpipes on it before selling it as the executor of the will. At least I think this is what happened, its a German spec car and I haven't the faintest idea really.

I can't say I hate the look, but it does feel slightly poserish when I kick the diesel over. It cruises like a mother fucker though.

I have a question on a used Mercedes. I wouldn't normally consider this as I'm not a used car person but circumstances have forced me to look for one.

I have a offer to buy a 1995 SL 550 (500?) for $4000. Outside of the color (black), I know nothing about the car. I have been allowed to have it checked out by a mechanic but my schedule hasn't allowed for it until next week at the earliest.

Given the age and likely mileage, is this a con in the making or is there some hope to get some decent use out of it (It would used for backup)?

If it's a well maintained car, and you understand that maintenance will be more expensive, I'd say go for it. That generation of SL is very solid, from back when Mercedes built the best cars possible. Being able to do your own work would make this car a little more palatable, but it probably isn't a good place to start. They're not super sporty cars, more of a grand tourer. Just don't buy a basket case Benz, of any generation.

It's post 93, which IIRC means it's biodegradable wiring harness era, i.e. the expensive electrical gremlin era. Mid 90s is definitely not "back when Mercedes built the best cars possible" (that would be the 70s and 80s), but rather the beginning of the decline in quality.

Ordered some new Arnott replacements for less than $700 shipped, hopefully this takes care of it and I don't have to chase gremlins.

Ended up cancelling my order since the symptoms don't seem to match those of the typical blown air spring. I think I had multiple issues going on with the Airmatic. This week I replaced (rather, I paid the shop to replace) the compressor, relay, valve block, and some miscellaneous filters/hoses in the system. A little under $1200 out the door.

The good thing is, I think this fixed the intermittent white warning light that was coming on sometimes on the MFD. This warning came on periodically over the past 2 years, but there were never any issues associated with it so it was not addressed as the shop told me it probably wasn't worth the time or money until there was a problem. The code read with the Star diagnostic indicated that the compressor was not pressurizing as quickly as expected. So it seems to me that it is likely that my compressor had been slowly going out for quite some time.

The bad news is that this did not fix my intermittent sagging in the rear. The car still, apparently randomly, drops on the driver's side rear. Sometimes it seems to hold pressure just fine overnight but as soon as I start driving it I can feel the car pull to the right, which I'm sure is great for the $1,000 tires. Pulling over verifies that this is pulling because the rear is dropping. Then again it sometimes runs perfectly and drives straight as an arrow.

Any ideas on what else this issue could be before I bite the bullet and replace the air springs? Rear level sensor maybe? The mechanic said that based on visual inspection the rear air springs looked almost brand new, and the level sensor did not throw any codes. Also, most of what I have read and what the shop told me is that when the air springs fail there is no partial failure - the car drops and will not raise up. When the car is turned off and bottomed out, turning it on results in it quickly pumping back up to the expected height but it may or may not stay there.

Nice!

Air springs can leak around the base, have you tried spraying the offending one with soapy water to see if it is leaking?

If its not an external leak it sounds like the air is leaking back through whatever valve controls the ride height for each wheel, which it looks like you've replaced.

Take this all with a pinch of salt. I don't have any experience on car air suspension, just trucks, but they are fairly simple. It seems like a leaking air pipe/connector would be a pain in the rear end to find buried in a car though.

RE: pumping back up and not staying there, if the compressor runs until it sees all the bags are inflated, it will turn off and send a signal to shut off the valves to each spring, if the valve sticks the air will come straight back out. I have googled a few diagrams for the airmatic suspension, some of them look like there is an electrical connector on each spring connected to a valve which controls air in/out, so maybe that valve has failed on that particular spring?

Most air suspensions will talk to the computer while driving. If you can get a scanner that will read codes, have a friend drive the car and see what the sensors are telling the computer.

I would bet there is a dead spot in the ride sensor, or a control valve is opening when it shouldn't. Try also shifting weight around and see if that helps.

Yesterday I started the car while the rear was low and nothing happened. The compressor didn't activate and the rear didn't come up at all. I Took the key out and started it again. The second time the rear instantly rose and it has stayed perfectly level all night.

warcake posted:

It does kind of seem like a valve issue as if there was an external leak it should be dropping after a period of time. I wish I knew more about the system because the only pattern I can tell is that it varies with starting the car.

Looking at my invoice it is not listed, nor was it discussed by the shop so I doubt it was replaced.

I managed to actually look at the car I was talking so I was able to procure a few more details:

It's actually a 1990 500 SL with roughly 84k on it. I'd thought it'd be higher
No damage reported though the car could use a good cleaning
Driver seat has a few punctures in it, Passenger looks OK
Stock radio was replaced but change can be reverted
Hard top has to be removed manually since those controls in car broke, all other functions work.

I do have pictures although they didn't turn out well due to fading light. It this still a good idea or should I move on?

If there's nothing wrong with it right now there probably will be something wrong in the near future. Definitely look for maintenance records. I think the traction control/anti-slip system is particularly prone to failure and is expensive to replace. Unfortunately when it goes out the ECU cuts engine power dramatically.
