Due to Kent's heavy product development and writting schedule he will no longer have the time to answer all the questions that have been pouring into our forum. Our goal has always been to be a resource to Mercedes owners who need help fixing their own cars. There is just not enough time to help everyone. We want to continue to try to help our current customers, so we are offering personalized tech help with your order of $75.00 or more. Some restrictions apply:

Fits the following: All 116 126 126 Chassis Diesels from 1977-1985. This is a brand new Genuine Mercedes Steering lock vacuum valve that is located on the back of your ignition lock assembly. The vacuum lines that control your engine shutoff go from the engine compartment to this valve at the lock assembly. If you are having problems with the car not shutting off this could be the culprit!

Good used tested EGR valve. Last one I have. Failure of this unit can cause excess smoke, poor idle, and/or rough shifting. Check to see if yours holds vacuum. Easy to replace. Also consider ordering new vacuum sensor switch. Also fits 1980 to 1983 240D with EGR valve.

This is that little vacuum valve that always gets it nipples broken off... It is located right behind your thermostat housing on the 1981 to 1985 turbo diesel engines. It controls vacuum going to your EGR valve. When it breaks it will effect the operation of the EGR and it may make your transmission shift hard. This is a genuine OE part.

Brand new Pierburg vacuum pump with new main check valve and gasket included. This lists for $428.00 and we have a few older stock at this special price.  Fits 1980 to 1985 123 chassis 240D, 300D, 300CD and 300TD as well as 126 chassis 300SD 1981 to 1985.  Just make sure your current pump only has one (1) main hose connection to the pump.

2007-12-05ALERT! Before you replace your suspected failing brake booster you might want to change the o-ring seal between the master cylinder and booster first. I have seen more than one expensive booster replaced when it was only a $2.00 o-ring. If your engine is producing good vacuum to the booster but your brake pedal still feels hard then at least check this o-ring.

This is my favorite set of tweezers for helping to hold small parts in place for assembly. The wide ones are particularly helpful when a second hand is needed to hold a small bolt or screw in place. Comes with seven different tweezers as shown. Good for car work. Not good for pulling hair!

Here is a little specialty part that almost every 617 turbo diesel owner needs or will need!. This plastic vacuum pin block is located on the top of the valve cover on 1981 to 1984 5 cylinder turbo diesel engines (except some late 1984 California models). With age and heat these little pins are now breaking off right and left. This is a brand new Mercedes part. It has 5 pins on one side and 6 pins on the other. We also carry a new rubber connector that goes on the outside of this pin block. CLICK HERE to view rubber connector.

Excellent used, working vacuum door lock actuator. Fits all 123 chassis 1982-1985. This is the late style actuator and can fit either the right front door or either of the back right or left doors in all late model sedans and station wagons.

Two excellent used, working vacuum door lock actuators. Fits all 123 chassis 1982-1985. These are the late style actuators and these two can fit either the right front door or either of the back right or left doors in all late model sedans and station wagons.

Excellent used engine driven vaccuum pump with new diaphram and check valves installed. Comes with new gasket and is ready to bolt on your engine. Fits all 1977 to 1979 240D, 300D, 300CD and 300TD.

Excellent used proportional valve for controling vacuum to your transmission for proper shifts. This plastic unit was used on 123 and 126 chassis turbo diesels from 1981-1984. Some California models used a different unit. This is a good used unit if you are having problems with improper shift in your 300D or 300SD turbo transmission this could be the culprit.

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.

To aid in trouble shooting you will need to acquire an inexpensive vacuum hand pump. Normal hand tools are the only other things you will need. For 1977 to 1980 cars I even have vacuum actuator repair kits available so you can replace any cracked diaphragms you may find.

Applies to testing vacuum problems and bleeding brakes on all chassis Pre 1960, 190SL, 110, 111, 112, 113, 114, 115, 108, 109, 107, 116, 123, 126, 201 and 124 chassis. You have asked for it so we decided to deliver. Here is my recommendation for the best vacuum test pump you can buy for the money. Over the years Ive used three different types of vacuum hand pump testers and out of these three this one has proven to be the best all around. It has the best feel of the grip when pumping, the greatest amount of vacuum created at each pump stroke and the highest durability. This unit has a brass body and is very well built. Must better than the Mighty Vac plastic units.

Excellent used working vacuum pump assembly with valuable working check valve included. This unit fits all 123 and 126 chassis 1981-1985 with the 5 cylinder turbo diesel engines. Also fits 1981 to 1983 240D. NOTE: Before purchasing be sure that you current unit looks just like this one. It is not uncommon that you could have an older style diesel engine in your Benz. If you are experiencing hard breaking and other vacuum related problems, it may be time to replace your ailing vacuum pump.
