Thanks for the information. I'll check into them further.
I found this on Google:
European Autohaus, Inc. 813-615-9444. 1105 E Bearss Ave. Tampa, Florida 33549
I don't know anything about the shop though.
I don't know about the quality of European Autohaus' work either; they are not far from my house. However, they sell wholesaled and consigned cars of a variety of brands from their lot. Sometimes they have many Mercedes, sometimes other makes (often, BMW, Jaguar). They do have a 3-bay garage, but I have never had them work on my car. They are listed on the Bosch site as an authorized Bosch repair facility for Mercedes.
I did have occasion to use Mercedes Complete yesterday, to install a fuel accumulator and a new fuel filter on my 450SL. They were quite familiar with the older cars (as well as new). They were quite happy to discuss what I thought might be the source of another problem I have with the SL, and offer help in determining the right parts so that I could attempt repairs myself if necessary.
I have two differing approaches to maintaining my cars. My S500 is relatively new. It does not have a lot of old parts; therefore, when I have a problem with that car, I want to have proper diagnostics done, the malfunctioning part identified, and replaced. I don't want to guess, and spend money "shotgunning" a problem with parts and no diagnosis.
I use a different approach with the 450SL. It is 33 years old, and so are most of its parts. I have no idea what maintenance was done by prior owners before I bought it 2 years ago. Therefore, I am willing to identify possible causes of problems, and if the parts are inexpensive or would be replaced as part of routine maintenance anyway, I will start with replacing those parts, and skip early diagnostics. For example, my SL occasionally stalls and must sit before restarting. The problem occurs only when the outside temperature is hot, and the car has reached normal operating temperatures, and operated there for some time. It is much like vapor lock - but it could be from another source, such as fuel starvation or excessively low fuel pressure. The K-Jetronic fuel injection system is not ordinarily prone to vapor lock, absent a malfunctioning part. A second, and possibly related problem is that the car sometimes starts "rough."
The rough starting is likely a fuel accumulator beginning to fail. The stall after operating for some time is likely a loss of fuel pressure - but that can be caused by several things - a clogged fuel strainer in the gas tank (under $10 for the part), an old and clogged fuel filter ($27), the bad accumulator $98), a failing fuel pump relay ($98), a failing fuel pump ($125), or a bad ignition module ($450+) are likely possible culprits. I approached Mercedes Complete with the initial phase of attacking the problem. They said they could run diagnostic routines for about 4 hours, and then replace what they thought would be the bad part. I wanted to take a different approach. I wanted to replace the fuel strainer, the fuel filter, and the accumulator. They were all of unknown age, and the strainer and accumulator were likely original to the car. Any could cause low fuel pressure or a blocked fuel line. In addition, the accumulator was about 90% certain to be the source of the rough starting. Mercedes Complete was game, and liked the approach. I supplied the Bosch parts, and they replaced the parts within their 2-hour estimate (and also did an oil change).
Indeed, the rough starting problem is solved. No matter whether the engine is cold, hot, or intermediate, it starts right up, smoothly. So now I have certain new components in the fuel system, some of which should have been replaced periodically anyway. If the stall problem is also cured, then 4 hours of diagnostics were not required. One old part that may have been identified through diagnostics wasn't replaced, just to await failure of the next component in the system. Deferred maintenance was accomplished, and we know which components are new. If the stall returns, I will replace the fuel pump relay ($97) myself, on the shop's recommendation. If the problem persists, I will have replaced another 33 year old part, and the only component requiring diagnostics will be the ignition module, the most expensive part, and the final likely source of stall problems of the sort I have been having. Little diagnostic time will be required for that one component. I will have spent no more than if I had had 4 hours of diagnostics, and the problem turned out to be the ignition module; but for about the same money I will have a virtually new fuel supply system. The money was spent on new parts (replacing very old ones) rather than extensive diagnostics. And the techs at Mercedes Complete were happy to advise me and work through the process.
Again, I approach the S-Class and the SL in an entirely different way. But Mercedes Complete was very cooperative, either way I wanted to go. That has not always been the case at the dealership, or at one other indy here in Tampa.
