DSG MULTITRONIC TIPTRONIC

DSG MULTITRONIC TIPTRONIC

There is  a common saying that goes something like this, "You can call a dog my any other name, but its still a dog." So whether you  call your Volkwagen, Audi, Seat or Skoda's multitronic transmission a gearbox or call your Direct Select Gearbox a transmission, it is still the same DOG, even though it is spelt DSG. The 02E Direct Shift Gearbox (DSG) is known  as the S-tronic 02E twin-clutch gearbox in Audi circles, and this 02E VW, Audi, Seat, Skoda – Multitronic DSG / CVT Transmission has a fully fledged Electronic Controller (TCM / TCU) onboard-- internal. Because of this, virtually all automatics and semi-automatics, wheter S-Tronic, Mechatronic, Multitronic, Tiptronic,  Continuously Variable Transmission (CVT) or a Direct-Shift Gearbox (DSG),  seems to be extremely troublesome. In fact VW,  Audi, Seat, Skoda owners have so much transmission trouble that in VAG circles it is notoriously known as DOG common. transmission trouble vary from difficulty with the gear selector lever, to stripped gears, to a stretched CVT chain, to faulty solenoids, all of which can cause the transmission to enter emergency mod a.k.a limp-home mode and present you with a flashing P R N D S display or a permanently lit reverse image display.  

In certain cases some of these faults may be corrected by simply renewing the Gearbox oil, or even software update but the bulk of the trouble is caused by the aforementioned Transmission Control Module (TCM), which is also also known as the Gearbox ECU or the Transmission Control Unit (TCU). A faulty Transmission Control Module (TCM) can cause a number of  faults ranging from an intermittent fault that  progressively gets worse.  It can cause the gearbox not to go into gear or to automatically go into neutral or loose power, or stop working when it gets hot. At times the Transmission Control Module (TCM) may be faulty yet not turn on any warning lights and the only way forward, is to scan the TCM to locate the problem.

The 6-Speed Direct-Shift Transmission (DSG) with Mechatronic J743 shares the same construction of a manual transmission but has the operation of an automatic transmission and fitted into the New Beetle, Golf, Golf R32, the Touran, Audi and so many other models, especially matched to the 2.0L TDI and 2.0L TSI Engines.

The cost of repairing  a DSG Gearbox ECU can easily set you back a good $1200.00 or more, and this  excludes  the cost of reprogramming (coding) the TCM, even though it is a fairly simple repair. The most common transmission problems are solenoids that get stuck in an open or closed position because  the transmission oil isn't replaced at the proper intervals, which then loses its viscosity and because of the heat, hardens between the valve body and the solenoid piston (plunger) causing it to seize.  When this happens the solenoid winding burns out or becomes high resistive. If the transmission oil is replaced as regular as it should, it will in fact lubricate the solenoid plunger (piston) and not get stuck. Problem is, the 7 litres of oil is also quite expensive but rather cost of the oil than an expensive TCM replacement and downtime of the vehicle.
The other problem is the engine heat and the gearbox heat and the transmission oil heat affects the wiring in the enclosed TCM, resulting in the ribbon cable becoming brittle which needs to be replaced when ever the TCM is serviced. The Gear selector switch also have several solenoids that could make you think that the transmission module is faulty even though its not. Its probably best to test all the solenoids before deciding to take out the gearbox.
