So, one of the advantages of Mercedes ownership is (supposed to be) the lifetime roadside assistance program.

I purchased my 320 last week, after a PPI at a dealership. They found a couple of nitpicky things as well as the fact that the battery was weak. The battery was indeed weak, it died within 6 hours of purchase of the car :( I bought a new battery at Autozone, things seemed OK.

The next night, I got home, shut it off, tried to restart - no go. It spun the engine but no start. Woke up the next morning, and it started fine as can be. Read the forum, got a CPS and installed it. And yes, I pulled the codes, but since it had already successfully started and run, I ass-u-me(d) that the codes could have cleared. Car continued to run well, drove it around on Saturday.

Note that I was 1100 miles from home helping my son with his selection of a home to buy, my wife was there with me.

Anyway, I left on Sunday morning, gotta work on Monday, wife stayed with son.

She went out to run errands today, all went well, top down, gets back to son's place, hits the button to put the top up and the top doesn't move. Light on the switch stays on while her finger is on the button and eventually goes out. Car won't start. Turns the key off, top switch illuminates for a moment and goes out. Key on, key off, top switch does nothing.

I'm not there but when I ask her she says the engine is not turning but there is a clicking from the dash.

Anyway, I call MB roadside assistance and the fine print says that they only come out if you bought from the dealer or have had service done at the dealer. Fortunately, I had the PPI done at the dealer and this was enough to convince them that I could get roadside assistance

Kudo's to them, this is not a rant.

They are coming out in a few minutes to diagnose, we shall see. However, I currently have a seriously p***ed off wife, if we end up spending a bunch of money on something 4 days after a PPI, there will be hell to pay (at least by me).

Fingers crossed.

Followup to the above:

Diagnosis at dealership - failed alternator. I will be conversing with the original location that did the PPI, this seems like it would be tough to miss (especially since they said the battery was weak)

It would appear that the CPS replace was for naught - though I do have a spare now - and the experience to change it again if necessary.

Another problem - I had an oil change done by a chain store (Jiffy Lube) since the sticker on the window said it had been due 500 miles previous (remember, my wife has to drive it 1100 miles home). I've gotten two versions of the story, they either didn't replace one o-ring or all the o-rings and so there was oil sprayed on the engine compartment. Dealership installed the o-ring(s) for me, I assume they checked/topped up the oil level.

The passenger door lock didn't operate (I knew this already) and so had the dealership check this out. They found that a control valve was leaking, this was fixed and the lock works like a champ now.

So, after a PPI, I was still out $500 for an alternator replacement (which I would have negotiated hard to get that price reduction had I known) and then done it myself. I'll be conversing with the inspecting dealership ASAP.

My oil change experience was quite negative, I'll be talking to them about the engine compartment cleanup costs.

However, my wife is still quite excited about the car (maybe as much as me). This is surprising because a car is a car is a car to her. :) :) :)

I'm looking forward to seeing my wife and the car this weekend, they're both coming home on Friday/Saturday. Plus, I already have a list of things I'd like to modify. Little things, but things nonetheless.

Never, evah, again :) Going to do it myself, I've already seen the threads about the oil removal pump, going to go that route.

One question though, what kind of interval do people go with their oil changes? (Bear in mind, it's approx 1M degrees in Texas in the summer time)

what mb recommends really based on model, between 10-13k, synthetic oil

but that would add up to 30k a year! that's crazy talk



“The necessity of 3,000 mile oil changes is a myth that has been handed down for decades,” writes Austin Davis, proprietor of the website TrustMyMechanic.com. He says that the economics of the oil change industry demand pushing customers to get their oil changed more frequently—purportedly as “cheap insurance” against problems cropping up—whether they need it or not. One of the largest oil change chains, Jiffy Lube, for instance, is owned by Pennzoil-Quaker State, and as such has an incentive to sell as much of the company’s traditional petroleum-based oil as possible

On our daily drivers, I change the oil every 5k. I put close to 20k miles per year, so that's 4 times each year. I drive that little Mazda hard, really hard. I realize that it's probably not necessary but figure that it can't hurt and is relatively cheap to do.

FSS Flexible Service Schedule (before a newbie asks)

The Mercedes-Benz Flexible Service System (FSS) permits a flexible service schedule that is based on your individual driving style. The next service due is displayed in the multifunction display within the instrument cluster. This display indicates the days or distances remaining to the next suggested maintenance. Once the suggested service due has been exceeded, the wrench symbol, plus the message “exceeded by” appears when the ignition key is on.
Each model has a separate service sheet, which defines the service required for that mileage and/or time limit. The Driving Machine offers a preferred maintenance schedule for owners who expect to own their car longer than 4 years. If you are interested please ask your service adviser during check in.
Each service sheet lists two service groups: Service “A” (small), and Service “B” (extended). Normally, the driving distance between a “A” service and a “B” service is approx. 14,000 miles, as a result the “A” service and “B” service alternate. The exception being if the FSS calculates an oil change interval of more then 14,000 miles, then a “B” service would be followed by a “B” service.
Additionally, any service required that is not mileage dependent is listed in the service sheets as: “Additional work”.
Maintenance service indicator message
The maintenance service indicator will notify you when your next maintenance service is due.
Starting approximately one month before maintenance service is due, one of the following messages will appear in the multifunction display while you are driving or when you switch on the ignition (example service A):
Service A in XX Days
Service A in XX Miles
Service A due now
The type of maintenance service due is indicated in the speedometer display:
Basic service (A)
Extended service (B)
Maintenance service term exceeded
If you have exceeded the suggested service term, you will see the following message in the multifunction display:
Service A exceeded by xx Days
Service A exceeded by xx Miles
In addition, a signal sounds when the message appears.
Some conditions that change the frequency & components of normal service are:
Operating in dusty, wet or muddy terrain
Frequent driving in dense city stop and go traffic
Repeated short trip operation without sufficient engine warm up
Ambient temperature extremes
Operating in mountainous/high altitude areas
Trailer towing
NOTE: Low mileage vehicles should be maintained at least once a year.

To each his own, but IMO if you are changing your oil more often than the FSS tells you to, you are just wasting time, money and resources. If you want to convince yourself that your synthetic oil is still good after XXX number of miles, have an oil analysis done and you be be convinced. I have had mine analyzed after two years and also after more than 10,000 miles and the oil was still plenty good to go further. There are also studies that show that not allowing your oil's additives to wear down between oil changes does more harm than good to your engine. Whether you believe those studies or not is another matter, but don't be sucked in by ideas that are 25 years or more old.

Len, I like your 240D with 349,000 miles. I am hoping that I can get that out of my Bluetec. It will mean that I have lived another 30 years.:)
Yeah, and for about the last seven years or so I've been putting less than 500 miles a year on it. I'm hoping to keep my E300D rolling to get close to that mileage.

To put a bit of closure on the new purchase saga, my wife drove the car from Cincinnati to Dallas on Friday - approx 950 miles. No issues to speak of, just one oddity, the cruise stopped at Little Rock and wouldn't re-engage. She refueled later but forgot to check it.

We were meeting in Dallas because our son moved from Houston to Dallas and I helped with that. After a day or so there we drove home to Austin, she in the Equinox, me in the SLK. Cruise worked like a charm :) Our neighborhood kids all ooohed and aaahed when I pulled into the driveway and our next door neighbor (who had seen the FB post about the purchase) hollered out the window that he thought we had been kidding about the car :)

Anyway, all's well that ends well; I have the car at work today (gotta show it off) and I'm hoping the local MB dealer has the trunk lift struts so I can exchange those.

More to come about the car I'm sure, but only upgrades/mods :)

I have just had a gas engine (Man engine) combined heat and power unit installed at work only a smallish one 104kw three phase but the service schedule is an oil change every 400 hours at 1500 rpm!

I queried that but I guess if you think that a car does maybe 40miles in an hour that is 16000 miles distance but at 17 hours a day 7!days per week they will be setting up a bed in the plant room

I am doing weekly oil sampling and testing so maybe can extend that a little
