W124, MPG Products to Increase Mileage

I noticed, recently, that there was what sounded like an exhaust leak in the engine compartment of my 1990 300D 2.5 turbo. In checking further, I found that the noise was on the intake side of the engine not the exhaust side. Checking further, I found that puffs of air(?) were coming out of a small half-moon shaped hole on the rim of the injection port of the last fuel injector (closest to the firewall). I bought your injector rebuild/test kit (monarch nozzles) and rebuilt all of the injectors and reinstalled them.

I own W124 230TE but the sls is not working for the last 6 month or maybe more, i try sending it to the workshop but end paying more $$$ but still no success, end up the system getting worst, i check & found the actcuator & the adjusting valve broken & missing. Now it just on the coil spring, with 2 adult seating at the rear the whole back sink down, the problem here is very difficult to get the part localy (Singapore)& costly to import the part.

My car which went from no start to running great for a month after I put in your Ultimate Tune Up Kit has suddenly been experiencing a dead battery. I installed a new battery when happened but the first morning the new battery was dead. I checked the forum and found and followed directions for trouble shooting an 84 300SD battery drain. I recharged the battery, disconnected the battery ground cable and put a test light between the ground cable and the battery negative terminal. The light lit brightly indicating a current drain. I disconnected the alternator plug and again the light lit.
