This transmission is only found in the Jetta Hybrid in the US market. This is not the most common of VW issues, but it is pretty cool how it works. This is also a little different video because I have never taken one apart. It is great because we can all learn something on this video. They are the VW and Audi parts experts. They have great prices and awesome service. Paul and the fellas at DAP are awesome. Trouble viewing? As always, your questions and comments are welcome. Please post them below.

Did you replace the mechatronic unit and if you did the car go well or something else happen Thanks. My tsi just failed after 40,kms no early warning flags, just D1! The repair is under way now, replacing the complete control unit. Apparently, recon units are available however the cost vs warranty against new is just not viable!!
Same problem with my Passat. The car just stalled, no warning,no sign, but a wrench on the dash board. Can i replace golf 5 engine and dsg gearbox with a polo engine and manual gearbox or only swap the dsg with a manual gearbox and clutch pedal. It only drives in Gear 2. It does not shift to gear 3 it only stays on gear 2. The repair amount was and it only drove kms.
No one has a clear answer. As my vehicle 1. Started but would drive in 1st 3r and 5th reverse gear there was no action or movement yet stationary. Gearbox had been stripped the forks and bearings were changed. Now installed the gearbox.John is a fervent writer, gamer, and guitar lover.

The transverse six-speed DSG transmission, also known as DQ, is a dual-clutch automatic transmission that is found in vehicles by a number of manufacturers. These manufacturers include Audi, Volkswagen, Skoda, and Seat. The DQ is a dual-clutch transmission that employs a combination of manual transmission gears and automatic transmission clutches in order to gain the benefits of both.
This particular transmission is old news, having been replaced by newer versions, but it has been used in so many vehicles that are still on the road today that it is most definitely still relevant. To defeat your enemy, you must understand your enemy. So it is with transmission faults. A traditional automatic transmission uses a number of clutch packs to produce the desired output ratio.
This works fine, but it has drawbacks, one of the biggest being fuel efficiency. Conversely, manual transmissions use solid metal gears and a single manually operated clutch.
This setup creates less resistance and better fuel efficiency, but it means the driver has to deal with pesky clutch pedals and gear levers. Using an advanced electro-hydraulic control module to control clutch application and gear shifting, the DSG can bring the driving comfort of a full automatic to the table while still getting the greater efficiency of the manual-style gears.
Furthermore, it makes use of a dual clutch assembly, where one clutch is responsible for even numbered gears and the other for odd-numbered gears, improving shifting quality further.
There are other variants, such as the 7 speed DQ, and the inline 0B5 transmission. Before we get into the transmission fault here, there is another cause of juddering which is far more common, and it is outside of the transmission itself. If you experience the juddering mainly when you start the engine and when the car is idling, often accompanied by a loud clattering noise, the problem is likely in the dual mass flywheel which sits between the transmission and the engine.
The flywheel consists of two plates that can move a small amount in relation to each other. This provides a cushioning effect when torque is transferred from the engine to the transmission. If the two flywheel plates sheer off from each other, your vehicle will lose drive entirely.
If your flywheel is fine, however, and the juddering sensation is most noticeable on gearshifts—particularly at lower speeds—the problem likely lies in the dual clutch assembly.
There are kits available that allow for the replacement of many of the components of the clutch assembly, and oftentimes that will cure the fault. However, sometimes the wear and tear is in the non-replaceable components, and a new assembly is needed. Default Mode—also known as limp mode and failsafe mode—is a failure state of the transmission where it detects a fault and limits itself to one gear typically third to limit damage to the transmission.
If the codes mention any sensors, gear ratios, or unexpected mechanical disengagements, the problem is almost certainly your mechatronic.Clutch 02E - 0B5 - 0BH - 0BT solenoids repair (Audi Volkswagen Skoda Seat)
It should be noted, however, that these companies are limited in what they can test for and repair in these mechatronic units. One particularly common symptom of a faulty DQ mechatronic is a partial or total loss of reverse, so be on the lookout for that as a strong indicator that the mechatronic is failing.
I have seen a number of instances of bearings wearing down, however. This typically results in a metallic noise when driving. I have known DSG transmissions with this symptom to be driven for quite some time with no ill-effects other than quite irritating driving noise.
If the mechanical components of the DSG did fail, it would be pretty catastrophic for the transmission. The fix is a bearing kit, assuming the problem is dealt with promptly, and no other damage has been caused. Adaptations are little adjustments that your mechatronic makes to things like how much pressure it applies to the clutches to compensate for wear and tear or driving style. Sometimes things can get a little out of whack, and in those cases, a reset of the adaptation values—followed by a proper drive cycle—can sometimes be enough to clear the issues up.
The affected part here is actually in the gear selector itself, rather than the transmission. Though it could also be a wiring or communication fault.After searching on here it seemed likely to be the filter o-ring so I went ahead and ordered one.
I went to change it today and after removing the airbox it was apparent that wasn't the culprit. Here's a pic of where the fluid looks to be leaking from: I cant figure out how to disconnect this connector.
Can someone tell me how you do it? I'm not sure if I can even get the seal that's in that plug. The tab on the right side of the round connector, rotate it to the left about 90 degrees. Yeah, I tried that, but it didn't want to give, and I didn't want to snap it off.
It almost looks like it's not even in there straight, but I don't see how this type of plug would even allow that to happen. As far as I know it's the connector for the mechatronic unit, and I can't seem to find where you can get the o-rings or connector separately.

Can anyone confirm this? TDI s : If the wiring harness is passing oil thru the connector there isn't much to do but replace the harness inside the tranny. Certified Volkswagen Nut Vendor. TDI s : There are just too many to list Chances are, the vent may have seeped a little out, especially if the box was a bit overfilled. I'd clean it all off, and see if it comes back in any short amount of time. I'm betting it won't. Certainly not enough to dive into taking the front of the car off and pulling the M-unit cover off which also has a seal that would need to be replaced.
If you like, wait until your DMF fails it will, eventually and you have to pull the trans out. THEN the M-unit cover will be super easy to reseal.

They are two- or three-dimensional circuit carriers with a high degree of miniaturization. Depending on the specifications and required quantities the MID are manufactured using either the hot-embossing process or laser direct structuring LDS.
MID-based lighting systems are characterized by their small size and high efficiency. Compared to conventional halogen lamps the size can be considerably reduced by using LED-diodes light-emitting diode.
LED-diodes also have a longer service life and the colour of the light can be selected. The LED lighting element represents the current standard. It is characterized by its flat structure, enabling it to be used, for example, in monitors. We also offer the manufacture of light diodes with UNC thread which have a constant power source.
This ensures uniform luminosity even when the battery is weak. They are used in the medical industryfor example, for laryngoscopes. Our microliter pump was developed primarily for use in the field of medicine and research.
It conveys small quantities of diverse fluids on the same principle as a peristaltic pump and consists of two components. The drive unit can be reused but the fluidics component, which comes into contact with the fluid, has been designed as an inexpensive element for single use only. This effectively avoids any cross-contamination. As an experienced specialist we not only manufacture microsystems in small and large quantities, but also provide support in the development phase.
