Another Mercedes V12 wire harness repair job.   Leave a comment

Autobahn performance is doing another air mass meter wire harness repair. We are getting lots of these cars in for the repair, even being shipped in from across the country. We can repair the air mass meter portion of the Body mounted engine harness without removing the harness. Do not attempt to cut open the body harness and repair the wires, this customer did and ended up cutting and damaging non deteriorating wires. You can see in the pictures the wires are molded into a pass-through loom it is impossible to separate and untangle the wires without damaging the entire harness. We have repair harnesses in stock to repair the body-mounted engine harness on v12 600’s. Usually, only the air mass sensor wires fail. $295 each 2 needed. The harness can be run alongside the factory harness sheathed in long lengths of heat shrink tubing and connected directly to the engine computers. The other harness’s common to fail are the lower engine harness (also called starter harness or positive cable harness) we can repair your damaged harness but it may be available at a reasonable price from the dealer (get me you VIN and I will get you a price) The throttle actuators have harness’s that come off of them and connect to the body harness. These harness’s fail internally, to check them you need to carefully make a 1-2″ incision in the covering of each actuator harness and examine the wires inside. If they are bad we can rebuild your actuators (done in house) $695 each includes internal motor, plastic gears and new cable harness connector end is  disassembled and re-used. The fuel injection harness sits on the top of the motor and is usually available from the dealer at a reasonable price. These can be rebuilt by us but must be inspected to give an accurate price. The body harness of the car usually does not fail or deteriorate on 129 SL’s if it is it probably should be replaced with new from dealer we could rebuild this harness but it would be expensive and time consuming.
