cold solder joint repair on Mercedes module   Leave a comment

At Autobahn Performance we can sometimes save money and time for customer by repairing cracked or cold solder joints. Manufactures seem to use too little solder at times and joints with high current / heat tend to crack over time. We are experienced at repairing these circuits. Here are some images of a recent circuit repair.Cracked_Solder_Joint

Porsche Cayenne coolant tee failure (plastic)   Leave a comment

Porsche Cayenne coolant tee failure (plastic)

We are working on a 2008 Porsche Cayenne V8 Turbo. The vehicle developed a coolant leak behind the engine against the firewall. After painstakingly gaining access, we found that a cheaply made plastic coolant tee connector had become brittle and failed. We obtained a parts schematic from Porsche but nothing in the diagram looks like this. This part is probably a Volkswagen part as the Touareg is built on the same platform. We could install a brass tee with hose barbs on it in place, but will give the dealer more time to produce the correct part. We may find that the part is available only as a hose assembly. We will add the correct part number and a picture of the new part when we find it.

Volkswagen 2.0l TDI engine BHW oil pump / balance shaft modification to gear drive assembly   Leave a comment

Old style chain drive balance shaft / oil pump assembly

The VW TDI (Diesel) engine of 2005 is prone to problems with the oil pump assembly. The oil pump that came in the car is chain-driven and the pump also drives the balance shafts that smoothes the engine vibrations. VW has updated the balance shaft and oil pump assembly to a gear-driven unit. The chain and chain-tensioner of the original style assembly wears and creates slack, lowering oil pressure. This can eventually break and cause no oil pressure and severe engine damage. The oil pan needs to be removed to gain access to the assembly. (This also requires lowering of the sub-frame assembly.) The front lower timing cover / crankshaft seal fixture needs to be removed and the factory chain-driven gear pulled off the front snout of the crankshaft with a special puller. Ours came right off with the special puller. We’ve heard of difficulties removing the gear and having it break and needing to be chiseled or cut off. The new crankshaft drive gear needs to be heated to the proper temperature and it will slide right in place. There is no key-way for the drive gear. The balance shaft assembly is timed with a special lock tool. The oil pan and lower timing cover are sealed with sealant only — no gasket. Special VW-approved Diesel oil must be used in these engines.

Mercedes SL600 with wiring problems   3 comments

We are working on a very clean and original 1995 SL600 (129 chassis) that has less than 30,000 miles on it. Unfortunately this vehicle was made by Mercedes with faulty wiring insulation that has deteriorated and caused short circuits in many components.  The main engine harness (just includes the fuel injector wires and a few others) is in the worst condition. The main body mounted engine harness has some wiring circuits that are bad, Mostly the air mass meter harness. This harness is over$5000 for the part and approximately 60 hours labor to replace. It runs from the headlights to the trunk of the car, behind the dash and under the interior. This job at the Mercedes dealer could legitimately be $14,500. Just for the body mounted harness. Here at Autobahn Performance Inc. in Ft. Lauderdale Florida we have developed a repair kit and procedure to repair this harness without removal for less than $1800. It will work on V12 engine in the 129 (SL convertible) chassis and the 140 chassis (4-door sedan or 2- door coupe). In rare cases more than the normal wire circuits are affected by the insulation deterioration and the harness is unrepairable. This is usually only in European-delivered vehicles and the sedan 140 chassis. If a wire suffers from insulation deterioration the entire length of wire must be replaced. Trying to splice onto a section of the wire will not work properly and will result in short circuits and possibly a fire. The insulation will start to crumble near where you are trying to repair it and you will probably make your problems worse rather than better.

The throttle actuators (electronic controlled throttle body, TBA Throttle Body actuators): There is one for each side of the engine. (note: the one on the right side of the engine feeds the air into the left side of the engine and vise versa) The actuators have a short wire harness coming out of them, it’s about 14 inches long, that connects to the body-mounted engine harness. These harnesses also have the insulation failure problem. The harnesses are part of the actuators and are not available as a separate piece from Mercedes. The Actuators can be rebuilt and new harnesses soldered into place. Again, do not try to repair these as you will not be able to properly connect new wires to the electrical connector end of the harness. Short circuits in the wiring of the actuators commonly cause damage to the E-GAS actuators (the control units that control the throttle actuators). These also can be rebuilt.

Wire insulation failure on Sl600 injection harness

we carefully cut a slit in the throttle actuator harness to inspect the wiring, In this case the wiring is shorted together and the vehicle should not be driven until repaired

Mercedes-Benz will not sell valve body for Mercedes 722.9 transmission   35 comments

Update 9/6/2013
We are able to get the 722.9 conductor plates and valve bodies for our customers. They take a few days to get and we have to provide the correct documentation but we are able to get the parts for most local customers. (The dealrs do not even stock these so it takes a few days if you bring your vehicle to the dealer) We have had issues with private dealer owned vehicles that have open titles. There is currently now way to get a TRP part if the vehicle is not owned and registered by an individual. 2013-01-31 16.33.40

6/2011
Mercedes now will not sell 722.9 valve bodies or conductor plate control units, even with the TRP paperwork completed. The newer Mercedes 7-speed transmissions (also called G-tronic) have the electronic control unit mounted inside the transmission these control units are failing frequently; with speed sensor codes (the usual codes are related to speed sensor faults). The speed sensors are not replaceable as they are part of the electrical conductor plate that bolts to the valve body inside the bottom of the transmission. The transmission does not need to be removed to replace the valve body or the conductor plate. A valve body does come complete with the conductor plate / control unit. Early valve bodies must be replaced as a complete unit but later second or third generation units can be repaired by just replacing the conductor plate / control unit assembly. We have replaced many of these and have the capability of performing the SCN coding to complete the installation of this repair.

These units are failing so often that the dealer has restricted selling them even in their own shop. To order a part the dealer must submit a request with computer scans and control unit log reports of the suspected failed vehicles electronics. The factory then sends the parts they deem necessary for the repair (conductor plate assembly or complete valvebody).

It’s rumored that Siemens VDO the manufacturer of the electrical control units is in a battle with Mercedes over the validity of failing units. Why should an
internal problem with Mercedes and its suppliers affect our ability to acquire parts and repair our customer’s vehicle? Mercedes is requiring the vehicles be
brought into one of their dealers for any valve body or conductor plate repair even if the vehicle is not covered under warranty and the customer is paying for
it. In our customers view this would be perceived as an inability for us to repair their vehicle and give the dealers an unfair advantage at gaining the
customers business. One customer lost for life could be worth hundreds of thousands of dollars.
