Classic Mercedes Benz diagnostics, consultations, inspections
STORY OF MY CARS
This is my first Mercedes-
1990 300E with over 180,000 miles in non driving condition at New Jersey repair shop parking lot. The interior was very nice. Body was very good also, except for front bumper cover. Previous owner was driving the car and his air pump pulley bearing seized. Accessory belt broke damaging power coolant fan and transmission coolant pipes. I removed the air pump and replaced pulley bearing. Went back to the parking lot, reinstalled pump, replaced transmission coolant pipe, refilled it and drove away. In that car I replaced engine mounts, installed Eibach lowering springs and Bilstein sport shocks, custom radio and subwoofer in rear deck, tuned engine, 17” AMG rims. The car was nice and fun to drive but I always wished it was 5-
1992 Mercedes Benz 500SEL black on black. I absolutely fell in love with it second I saw it. No dents on the body, no damage to interior but it was very dirty though. The main problem was engine failure. One of the distributor rotor broke. The car started to misfire but owner drove on four cylinders for few more miles. Driving on four cylinders put lots of strain on the timing chain. Top chain guides broke and chain skipped two teeth on camshaft gear. Luckily valves did not bend. I towed the car to my friend’s parking lot, opened valve covers, put new chain guides, chain tensioner, new distributor caps and rotors, set timing, started the car and drove away. I put lots of time and money restoring this car to its glory, could have bought a nice running S-
I drove 500SEL for more than two years. One day I saw an ad for 1996 E320 for sale for $1200. The car would not start, the starter would not engage. Went to look at it and the car turned out to be very nice except dent on passenger rear quarter panel. It had a custom entertainment system, custom built subwoofer enclosure in the trunk, sport suspension, 18” AMG rims, back up camera, headrest monitors, playstation2, iPod dock. The problem was the flex disc failed and drive shaft separated from transmission flange. Emergency brake cable wrapped around drive shaft bending gear selector link. Gear selector link pulled neutral safety switch out its alignment. Without neutral safety switch the car didn’t crank. I decided to take a chance and bought it. Had it towed to my friend’s repair shop so I could use lift. Bought new gear selector link and flex disk. I bent neutral safety switch back and the car started fine. I drove it for a little time. I still had my 1992 500SEL at the time and it was really hard for me to make a switch from S-
In 2008 on one hot day I and my girlfriend were driving from the beach and we stopped by a car that was for sale locally. It was 1999 ML430 silver on gray. It had about 110,000 highway miles. Out of state car in excellent condition. I took it for a test drive and it performed excellently. Bought it. S-
As of 2022 I still own it. Use it mostly during snowy winter months and for towing trailers. Had to repair some brake lines, fuel line, alternator, thermostat, some bearings, brakes, etc. With over 200k miles this car still runs strong.
I missed S-
In July 2011 I sold 1994 S500 and bought 1997 S320 with 117,000 miles. It came with full dealer history including head gasket replacement. S320 has much weaker I6 3.2 liter M104 engine than mighty M119 V8 5.0 liter. You can feel some lack of power going uphill with loaded trunk and full tank of gas. In the city, there is plenty of power even with A/C on. Gas mileage is great and engine power output satisfies me completely. I love HFM engine management along with 722.6 transmission. There are some repairs I had to do to a car, but it was in excellent condition. In 2017 I replaced both front springs, lower control arms, sway bar links and bushings, brakes, water pump and serpentine belt. Very reliable car. Gave this car to my mother.
In the beginning of 2012 I got 2002 S500. It ran and drove. AirMatic was not working, car sat on the floor with front struts not holding air. And lifters were noisy. It turned out that one front strut was blown and another one was leaking from top seal. Replaced blown strut with a used one and repaired top seal on the other front strut with repair kit. Suspension went up and did not drop after all. The valve train noise turned out to be a very serious issue-
Around March of 2012 bought a 1997 C280 Sport. The car had a problem with flooded transmission computer, TCM, along with other issues. It would start and drive but would not switch gears. Put in TCM from my 97 S320 and drove the car home, about 15 miles. Ran OK but would not shift past third gear. And under closer inspection found out that oil mixes with coolant. The head gasket was leaking. Removed the head and replaced the head gasket. Bought used TCM with same part number but transmission still would not shift past third gear. The problem was inside shifter assembly. Disassembled the shifter and found corrosion inside the gear selector module. Cleaned contacts, repaired W/S switch that was also broken. Gave it to my girlfriend. She sold it in 2014.
Around June of 2012 bought. 91 500SL. The car would crank but would not start, had to tow it from Connecticut to NY. Under closer diagnostic found no power to ECU. Turned out to be faulty ignition switch contacts and some other wiring issues. Replaced contacts and the car would start and drive. This car became a long restoration project. I replaced seals in all roof cylinders, replaced whole soft top frame due to chrome oxidation, installed custom subwoofer behind seats, replaced seats, had lower covers repainted, repaired seats and mirrors control, rebuilt soft top control module, rebuilt transmission valve body, fuel distributor, water pump, front suspension, etc. And finally fully tuned CIS-
I bought 2000 S430 in very nice condition with 140k miles. The car had fresh water damage to computers on the passenger side by the windshield. It would recognize smart key and power would come up but would not crank. Under closer diagnostic it was determined that transmission computer, TCM, was completely non functional. My Star Diagnostic would not read it at all. Main ECU was reanimated by cleaning and soldering few terminals. TCM was also damaged. It was determined that the main power chip was not good. I happen to have old TCM from C280 that was flooded also but power chip was still good. Replaced chips and original TCM started to work fine. Cleared all codes and car would start and drive fine. Other small issues came up but were sorted pretty fast. Also, second smart key did not start the car. Found cracked transistor on the board. Bought used key and sourced transistor from it. Second key works fine now. AirMatic had issues and dampening system had issues, but they were resolved. Radio didn’t play due to failed fiber optic ring in phone or voice recognition modules. Just bypassed them for now to have sound. While working on radio I hardwired bluetooth module into cassette circuit inside the radio. Sound and operation were so good that I installed same adapters into my other cars. Drove this car for awhile and sold it in the summer of 2015.
While having 2000 S430 I bought 93 600SL with less than 26,000 original miles. This car is in Brand New Condition. One owner, climate control garage kept. Drove it from Chicago back to NY. This beautiful car is for sale. Click below for more information
Bought 1995 S600 coupe. Always wanted V12 W140. This S600 is in very nice condition, but mechanically it was a total disaster. The engine did not run at all and transmission needed complete rebuild, had no reverse and slipping from 2nd to 3rd. The exhaust was cut and catalytic converters removed along with O2 sensors! The door lock pump was burned. And on top of all that engine was foamed by the fire department. Catalytic converters started to smoke while driving and previous owner called the fire department due to smoke coming from under the car. After I started the engine only 9 cylinders worked, drove it on 9 cylinders from PA to NY. Lots of work was put into restoring this car to bring it back to it’s glory. After owning and driving it for many I gave this car to my bodyman in 2021.
In early 2015 I purchased 2003 CL600 twin turbo V12 Renntech tuned, W215 chassis with 115,000 miles. Car is in excellent condition in and out. It suffered ABC suspension failure along with misfires, intercooler pump issue, Evap system issue and other minor issues. ABC high pressure expansion hose broke. To replace it engine needed to be raised. While at it, I replaced some other suspension hoses. When high pressure hose broke hydraulic fluid covered all coolant hoses and front of the engine. Coolant hoses became soft and while I had access I replaced all of them. ABC pump was also destroyed driving car with no hydraulic fluid. Replaced pump with rebuilt unit. Recalibrated vehicle height. I rebuilt one ignition coil pack but second coil pack needed to be replaced with new one. Intercooler pump was not original, connector was broken. Adapted connector and made a bracket to hold the pump in place. When replacing coolant hoses I drained intercooler circuit. Mercedes uses special equipment to refill and bleed intercooler circuit. It is independent from the main engine coolant circuit. I made my own adapters and bleed the system. Also replaced transmission conductor plate, fluid, connector. Car runs and drives fine now.
In early 2016 I bought this 1994 SL600 with less than 29,000 miles. Car is in excellent condition. It was always garaged and came from California. This V12 has electrical gremlins, suspension needs repairs, soft top does not work, couple of small cosmetics.
I rebuilt both throttle bodies, rebuilt all wiring harnesses, replaced suspension accumulators, repaired soft top, rebuilt front roof cylinders, installed bluetooth into factory radio, repaired suspension manifold, all other electrical gremlins sorted. Sold this car in 2018
In the beginning of 2018 I got this 2003 S600 from my friend. This car was left sitting outdoors for many years -
In 2021 I got this 2007 S550 4matic with 86k miles from Florida. The car ran and drove but needed few repairs along with cosmetics to be sorted. So far I replaced motor mounts, battery, alternator, few cosmetics, and bluetooth added. As of 2022 this car is getting a complete repaint due to clear coat issues. A few other things needed to be done to it when I have some free time but it drives fine. Work in progress…
At the beginning of 2022 I got this new project car -
