I saw the various posts regarding how sooner or later, Mercedes will come up with a solution for this. Most of those posts were from 1999 or early 2000.

Being that its now 2003, does anyone know if MBUSA has gotten anywhere with this seemingly common problem? Is there a class action suit or something? My car (99clk320) is no longer under warranty and I don't want to spend the money on a new sending unit if its just a tactical fix that will break again with time...

Thanks all.

CAN is the computer network (just wires). Sensors are interpreted by the controller they are hooked to and that processed info is transmitted through the CAN to any other controller interested. In the case of fuel tank readings the controller involved is the Instrument Cluster. If the engine management controller uses this info (as it does for evaporative leak checking) it gets it through CAN.

No software in the CAN.

I've posted on this subject many, many times before. I even contacted VDO about it specifically - they denied a problem with the gauges and blame it on the sending unit. Every Mercedes I've ever owned has had this problem - from all the feedback about it, it seems to be a very common problem. From a 1971 250 sedan to my present 300E. I think the basic design of their sending units has remained the same and hence the recurring problem. You'd think the engineers that designed such fine cars could fookin' design something as simple and crucial as a fuel gauge properly!!!!

Very annoying problem.

Hell, every old and dying P.O.S. American rustbucket we have sitting up at our family's farm has a perfectly accurate fuel gauge. Even our 1967 Chevy truck has a steady fuel gauge...

Get on it Mercedes!!!!

Well, your statistical quest is drawing some bogus results probably due to the sample size.

I have been working on MBs for 30 years and have fixed less than 2 a year. Probably about one tenth the amount of wheel bearings I have replaced.

Every German car does this the same way and there may be a new problem with late model units that have more than one sensor and maybe some more problems in Ca. When I think of common failures over the years the amount of fuel gauge problems wouldn't even be on the screen.

I not jumping on your bandwagen.

That's OK, my wagens are full...or are they...wait...I can't tell...

Well, I'm still not convinced...maybe the gas is cleaner in your neck of the woods?

All three of my cars (one is originally from Philadelphia) have the same problem...quite a few people here have the same exact problem...even with new vehicles. All this is coincidence? Granted the statistical sample size I'm hypothesizing with wouldn't hold up to any 'T' test worth a grain of salt, but I'm still not convinced.

All I'm saying is that perhaps it is not the best system given the apparent failure rates. It is comforting that you've only had a couple to replace. Maybe my 11th Benz will finally provide me with an accurate reading.

This is typical Mercedes. They have a problem, and they know it. But, a recall or goodwill program costs money. Since MB has had to shuffle billions in Chrysler in the last few years, they are getting a little tired of writing cheques.

So they pretend it doesn't exist. They did it with the FSS equipped dino-oil vehicles and they'll just keep doing it. They hope the owner reaches the end of the warranty, and then flip you the bird.

Now, this is not a unique situation among car makers. They all do it. It's just that MB customers are not Corolla buyers. We're pretty smart (most of us...) and the internet has meant a communications explosion. They used to get away with it as we weren't able to share the knowledge of the problems.

Right now MB has harmonic balancer problems that they are trying to dodge. They have fuel sending unit problems they're trying to dodge. They have bad wiring harnesses they have just about managed to successfully dodge. They have just about dodged the M104 head gasket bullet. They lost the lawsuit concerning the sludge problems in dino-oil FSS cars, but will work hard to avoid paying out a red cent in claims. You'll have to prove that your engine damage is indeed covered under the terms of the suit and it's warranty program.

Dealers are part of the problem, but what else can they do? Can a service writer be honest and tell you he's done dozens of balancers lately? No. He's got "lawyer tape" wrapped around his mouth. They just go ahead and lie.

In the US, you have some consumer protection with regards to lemon laws, but even those laws can be carefully circumvented by wily makers. Many people give up the fight and just sell the offending vehicle. Mercedes couldn't care less, it seems, that they've lost a customer. Right now their attitude is that their are legions of "new" MB customers to be had, and losing a few along the way is the cost of doing business.

What has this got them? Publicity, and lots of it. Their fall from grace in reliability and satisfaction ratings has been plastered on the pages of some of the most widely read consumer and news journals. German press has been merciless to them. But, their sales continue to sail along.

But for how long? This kind of stuff catches up with makers. Ford is still on shaky financial ground thanks to quality problems, and MB's own Chrysler was nearly broke (again!) int he late 1990's thanks to their trying to dodge rotten trannies and peeling paint.

"Fool me once, shame on you, fool me twice, shame on me."

Consumers are not the fools many makers think.
