My guess is that the shop that did the work knows very little about that transmission or those cars all together. Those mech units have a set height for each finger"hook" that in the mech when installing. If you install and miss a finger "hook" or have them at the wrong height you will the same issues. Once installed, they need to be adapted and gear recognition sensor needs to be calibrated.

VCI is the head or dongle $1500, software is a free download once you register however $900 license fee is separate and is annual. Without a valid license file you cannot even install ODIS. Sure there are cracked versions out there, but without a valid license, server certificate and geko ID you will not be able to perform any security functions like online adaptions. It will be just a scan tools for codes with test plans for codes and some basic settings that can be done offline.

Yes some shops and some individuals use certain expressions interchangeably, when it means other things. Is any diagram for the finger hooks at the mech unit to eliminate instalation issues in case.
Previous owner said 1,3,5,7 shifted perfectly and R,2,4,6 were late or slipped. What parts have the component protections and how is possible to know/what to look for ? Dual clutch system, so it means one part worked good and the other not. Right now nothing works. According to the previous owner, they changed and put a "new" mech unit, he said the old is in the trunk, but I only found 2 electrical plates and 3 solenoids. I had the plan to order a "mech unit repair kit", which has the 2 electrical plate and some cases 3 solenoids. Also at the case of having those changed does it require component protection coding ? Or only VCDS adaptations ? Also I need good recommendation link for parts, "mech unit repair kit", which has the parts, which responsible for R,2,4,6. Thanks

Component Protection is tied to the TCU, not the connecting electrical plates or solenoids.

Finger height is determined by production date and serial number. You need to match correct finger height with factory repair manual specs. To me it sounds like they installed a mech unit repair kit. This will not fix the issue. A new mech is probably upwards of 2-3 grand.

After reviewing your faults. I would assume that the boards were changed and nothing else. Juding by the faults stored. I would say the boards are either not correctly installed or not connected. You need to drop the mech out and post some pictures. Where in USA are you? The fact that you have 2 boards and 3 solenoids tells me you don't have factory parts installed but rather cheap china garbage at best. As solenoids are not available separately from audi.

Last week I had to tell the owner of a 2012 A5 3.0 TDI quattro cabrio (6 foot four and the size of a house) he needed to scrap his car as the failed 0B5 transmission would cost £7k to rebuild with a one year warranty or £13k to replace with a new VAG unit (two year warranty) as VAG do not offer an exchange unit. These transmissions were designed to reduce CO2 emissions, how can scrapping a ten year old 88k mile high end car be low CO2? Regulation gone mad, tailpipe emissions are only part of the story… a small part.

Sounds overly dramatic to me :) What's included in that rebuild price? One can always roll the dice on a used transmission or just sell the car as-is.

It won't be too long until we're asking the same sort of question about BEVs when their batteries need to be replaced. In fact, it's already happened with the first-gen Tesla Roadster. A replacement battery for one of those costs north of $25k.

0B5= Obselete Bullshit 5. Fail all the time. I don't dare touch anything that's a automatic, 01E for the win.

... Or convert it to proper 3-pedal operation. :D

Facts manual for the win I rather change a clutch once every 100-140k miles than deal with automatic garbage.

Good to know. In case of putting another used transmission unit, does it require component protection coding ? I guess the original TCU (is outside of the transmission) can be used with the other used and good transmission. Does anything in the transmission as component has protection ? Just checking, what would it take to change the whole transmission. Definitely would like to eliminate ODIS use. I can do adaptations with VCDS. Thanks

Likely tomorrow I drain the fluid and let the mech unit down and take some pictures and post it. Maybe find out that it s a cheap brand or not correctly installed. I ve found out recently from previous owner that, he got only 2 plates and 3 solenoids, new, not from audi. And yes a new mech unit is about the same as a used whole transmission 2-4K. Does a mech unit has components with protection coding ? Also what part is responsible for R, 2,4,6 gears (they were late or slipped) ? I think that should be changed to solve the original problem. Appreciate your clarifications

Checked with previous owner today and yes 2 plates and 3 solenoids, which were new and not from Audi, brand is still a mystery, unless there is some marking on them. When I take the mech unit out, I can see. I m in SC Myrtle Beach. I think I have 2 options, an original mech unit repair kit (2 plates and solenoids with Liqui Moly 8100 fluid) in case I have good chance to fix the R, 2,4,6, shifting slipping problem, it would be cheaper and less work or a used good transmission.

Yeah that s an option going manual. Likely more costly on the other hand, I guess long term solution for the transmission problem.

Yes, it will. TCU is a part of the mechatronics. It's the part behind a flate metal plate, to which the two circuit boards will connect to. Pictures on the internet suggest (Google "0b5 tcu") that the TCU can be removed from the mechatronics. Though there may be caveats, which I don't know.

Have a look at this from page 24, so You can get an idea how the 0B5 works. Page 36 may give an answer to your 2-4-6-R question -> https://procarmanuals.com/pdf-onlin...ons-7-speed-dual-clutch-gearbox-0b5-s-tronic/

If you can find one used, there are so many variations and what if it also goes tits up? I refuse point blank to fit used gearboxes. The rebuild cost was new clutch pack, mech and the sector parts that wear plus fluids and labour but I don't build boxes myself, thankless task.

Can you post pictures of the plates and solenoids? Also post pictures of the mech once you have it out before making any changes to it if possible.

Variations of the box are a fair point. If it goes tits up, that's why I called that rolling the dice. The client should be aware of this possibility from the outset.

If a person knows how to drive a manual properly, and doesn't intentionally abuse the clutch, it can last much longer than that. However, I suspect that driving a manual at all, much less properly, is rapidly becoming a lost skill.
