Running badly means poor performance. It happens sooner or later to EVERY diesel owner. The word "performance" is often used to describe how well a diesel engine runs once started. The principles discussed will cover all Mercedes diesels from the mid 1950s to the mid 1990s. Throughout this manual I will use this word to discuss a number of common problems. How performance is rated can mean different things to different people. In the following pages I will relate diesel performance to the following four criteria:

• How much power does it produce?
• What kind of fuel economy does it deliver?
• How smooth does the engine run?
• How much does the engine smoke?

These 3 illustrated manuals will help you quick start the process of converting your Mercedes diesel to run on free fuel! Stop going to the pumps!

With diesel fuel approaching $5.00 per gallon you cant tell me you are not interested in this subject. I know you may have lots of questions. To begin you must decide if you really want to do this!

From my many years of working professionally on Mercedes diesels I have learned fuel injectors are the single most neglected maintenance item. I believe there are a number of reasons for this. Partly it may be the mystery surrounding how injectors work and what needs to be done to service and repair them. Then there is the false notion that like the engine they will last forever. And finally, it can be very expensive to have a shop replace the fuel injectors. You may even have said to yourself, the engine seems to be running fine so why bother spending the money?

This is the first release from Kent Bergsmas new Advanced DIY Mechanic Series of repair manuals. This printed and wire bound guide will teach you everything you have ever wanted to know about how your pre-glow system works, how to quickly diagnose faults, how to repair and replace failed parts, how to prevent further problems, and how to upgrade a sluggish glow plug system.

The manual is printed in an 8.5 x 7 inch size and is 42 pages in length with 80 drawings, photos and illustrations. Knowing that this manual will be handled many times we have added a clear plastic front and back cover to minimize dirt and grease contamination. It is also printed on heavier 32 lb. bright white stock paper. Table of contents include:

Being locked out of your 123 trunk can be very frustrating, especially if you left the ignition keys inside when you closed the trunk lid! If you are locked out and still have your keys sometimes you may not be able to open the trunk due to a failed locking mechanism. And there is no way to get through the back seat to open it from inside either. In this short manual (Sourcelet) I will describe the tricks I have learned to get into a trunk that will not open....and do it fast!

This is a must read for anyone who is currently running or seriously thinking about running his or her Mercedes diesel on straight vegetable oil (SVO). This is a followup to my introductory guide, Dine Out with Your Diesel. It contains a higher level of technical information on the problems and challenges of long term operations. It has been said that knowledge is power. This is really true when running on SVO / WVO. If you do not have any knowledge of how your system works or what needs to be done to maintain it, then you are going to literally lose your power. The system will only be as reliable as YOU make it.

Are you plagued with a diesel that wont turn off when you want it to? Has it been slowly taking more time to quit when you turn your key off? It is time to fix it before you have more problems! This troubleshooting guide is directly applicable to the following models: 1975 to 1976 115 chassis 300D. all 1977 to 1985 240D, 300D, 300TD, 300CD and 1978 to 1985 116 and 126 chassis 300SD (pictures and illustrations were taken from work on these cars. The instructions will also apply in principle to the later model 201 chassis 190D, 124 300D and TD, and 126 300SDL and 350SD to 1993.

FITS ALL 190E and 190D 1984 TO 1993. This is the repair manual you 201 owners have been waiting for. If your blower motor has been intermittent or some days it will not come on until you drive for a while, your heater motor brushes are most likely at the end of their life. Try this simple test. The next time your heater motor will not come on try slamming the door. If it suddenly starts running it could be that the brushes are just not making good contact. If your 201 has more than 120,000 miles total,  then the brushes are something you may want to replace as a preventative measure. 15 or more year old heater motors are very prone to failing. If it has not failed yet, most likely it will sometime soon.

This guide is written specifically for owners of 123 and 126 diesels up to 1985. There are some sections that apply to the 115 and 116 chassis but it is not specific to those models. This manual covers understanding how the vacuum system works, common symptoms of trouble, possible causes, and testing and repairing the problems. Deals mostly with issues from the firewall forward like testing the vacuum pump, repairing shutoff problems, finding leaks, etc.

For all 123 chassis cars with vacuum door locks from 1977 to 1985. Now you can finally fix those pesky vacuum door locks yourself! Failure is almost always caused by vacuum leaks in the system. This 28 page manual with 55 photographs will take you step by step through the process of quickly finding and repairing those leaks. Starting at the firewall and working all the way to the trunk/deck of your car, I will show you how to isolate the problems even without having to take the door panels off.

How many times have we (and I am talking about myself here) done an oil change on our vehicle, looked at the odometer and said to ourselves, I will write the mileage down later. I know that I have even tried to memorize the mileage, only to discover a couple months down the road that I am asking myself, Was that 82 or 83 thousand miles?

Once a door panel is removed, there are a number of maintenance items that can be attended to which are also covered in this manual.

Burned out glow plugs are becoming an increasing problem in the 60x. engines produced from the mid 1980s to the mid 1990s. This 60x. group in question includes the four cylinder (601) engine that came in the 1984-1986 190D 2.2, the five cylinder (602) engine that came in the 190D 2.5 and 300D 2.5 from 1986 to 1993, and the 6 cylinder (603) engine installed in the 124, 126, and 140 chassis 300D / TD (1987 only), 300SDL and 350SDL.

Older Mercedes have a very effective emergency brake design which was virtually the same on all models from the late 1960s right up through the early 1990s. The actuating mechanisms are all mechanical and are controlled by a Y cable under the car. This cable is pulled by either a hand or foot operated lever.

If you have been around Mercedes diesels for any length of time, you have either asked this question or have had to deal with trying to find the answer. When troubleshooting a no-start problem it is always best to check the simple things first before moving on to the more difficult repairs. This guide covers 115, 116, 123, and 126 chassis diesels from 1969 to 1987.

This is true when troubleshooting any mechanical problem, but particularly true when dealing with starting issues. When the problem can not be fixed quickly with the simple checks I recommend then I will take you through a detailed checklist of everything you should check to determine why your diesel will not start. The manual is broken down into sections dealing with the three types of no start situations.
