Just double checking... when removing tcm battery does not need to be disconnected as long as key is off and remains off. Correct?

 

Correct, I did not remove battery when doing my T. I replaced the TCM, did accelerator reset when done, and that was it, really. No need to even keep the battery charging, since you're not flashing anything.

 

Thanks

 

Have an extra 2013 module for sale, can also be used for a 2014 $650

This allows you to keep your original module

 

Hmmm I would be interested. How much would you give me for my core TCM?

You might want to read that 2nd line again.

 

Y’a I saw that. But did you ever think that maybe I don’t want to keep it?

So buy a flash instead of a spare module 🤡

 

My only guess is that OP is trying to avoid down time i.e. not have to remove the TCM, have it shipped out, flashed, and wait for it to come back. The car is pretty much useless until then.

 

You got it my friend!

Troystg up above had some great pics- made it a lot easier for me to replace it.

USPS was very slow due to Christmas rush- just got the TCM yesterday. Installed it today and went for a drive around the valley.

I think it is much improved. It actually uses second gear- before it would just kinda "skip" over it. It no longer tries to hold gears and rev up to 2600 RPM or so and just hang there when the engine is cold.

Doesn't seem to have the delay when entering an intersection with a yield sign- so when coasting at a slow speed then giving it gas it used to have a delay then a clunk as it suddenly figured out that it should be driving.

Very happy with it. It's the way the transmission should be.

Happy to hear this

 

@yrktreg It seems that my new user status disallows for sending out private messages. Please send me your contact information if you are still providing TCU flashing services for the Cayenne Diesel.

@Troystg Thanks for the pictures and procedure on swapping the TCU. That really helped me understand where to look and purchase necessary tools required before starting the job.

 

My pleasure. It may make yktrgs job easier(less questions to answer over and over) and might ease the fear of the unknown to first timers like me!

 

Hi yrktreg! I would love to get the the pre-fix on my 2015 Touareg TDi, but its my daily driver. What do you offer? Please send me your contact info as I am a new member. Thank you!

 

Sorry for the double post, but I just acquired a spare TCM and should have it in a few days. Let me know the process to get this done sir! Very much looking forward to the pre-Fix.Thank you!

 

I just spent a couple days driving on my tuned TCU I got back from Joe this week for my '15 Cayenne. Couldn't be happier with the results. While USPS Priority took a week to travel only a 5 hour drive away, Joe turned around the tune quickly and graciously sent it back 2nd day back.

Most noticeable is the shift pattern while the car is warming up. No more hung shifts and holding high RPM. Very happy with the performance regained.

I was able to remove and reinstall the TCU without removing the seat but just moving it up and forward. From there, you pull the carpet up and stick your arm in to feel the TCU, press the release tab on the sides and pull it out.

I'll bought a spare TCU (0C8927769AG) that I will be putting up for sale on eBay unless someone here would like to buy it.

I'm happy that you are happy

 

Hi @yrktreg are you available to turn these around now? I'm ready to send in my module but am trying to plan it so I can limit my downtime.

 

Send away, I can usually get them programmed and back out the same day, if not the next day for certain

Just follow my other post with instructions

 

I have a spare module coming in for 2014 Touareg. Will be headed your way today or tomorrow. Do you send them back with Touareg coding or Cayenne coding and is one able to code between the two with VCDS after the flash like "normal" without issue?

 

I normally do the cayenne coding unless asked otherwise, and yes you can switch back and forth with VCDS like before

 

@yrktreg , not sure if I’ve posted enough for my pm to go thru.

I’m interested in a tcu flash for my 15 cayenne diesel. Could you ping me please?

tia!

 

Sent you a reply last night

 

Hi yrktreg, hope things are going well for you now.

I have a 2011 Touareg TDI and I too am not happy with the post-fix coding.

I have a source for a used spare TCU from another Touareg TDI. Would I be able to send you that TCU from the different car and have it work on mine after you have it recoded?

Thanks!

 

As long as it is from an 2011-2012 TDI yes you can, other modules won't work for you.

I have a post on here with how to instructions on sending it in.

I am hopefully going to feel well enough soon to post up the exchange list/ and extra units I have for sale.
That is for people that want to have me send them a unit and they send me their back, or the extra units are for people that want to be able to swap in and out as needed.
IIRC I have 2 2015-16 Cayenne Modules, 1 2013-2016 Q7 module, 1 2013 Touareg module, and 1 extra 2015-2016 Touareg module for sale.

 

I bought an extra and the original has not been back in!!

Tuner box is on the way so between the two, more hp/tq, better shifting and no voided warranty. Can switch back to OEM very quickly.

Just got this done on my Malone stage 2+ Q7. It's a whole new machine. No more hunting for gears. No more high rpm stall converter like symptoms. It starts pulling at 1000 rpm immediately with very little throttle. The gear indicator is nice to have! Joe you rock! If you are on the fence about this don't be! Just do it!

 

Thank you sir!

It was very nice meeting you, wish it wasn't a torrential downpour and we had more time to chat.

 

Hi @yrktreg ,

Hope all is well! I'm interested in your TCM flash for my 2013 Cayenne Diesel.

I'm running a GTD2872VRZK and the "post-fix" shift points are less than ideal.

Thank you!

 

Just messaged you back sir

 

Just got the TCU refresh in my 2012 Touareg. And man what a huge difference! I’ll never understand why VW thinks it’s okay to send that update out. There has to be some middle ground between pre fix and postfix tunes!

 

You got the works sir

Glad to hear it is a HUGE difference for you

 

I have to say what a wonderful group of people we have on here.
I have met and received messages, emails, etc from so many of you and wow what a great group of people.

Thank you to each and everyone of you for the support.

 

I am currently running 09D927750LD 3405 (2010 V6 TDI 7L). Is that pre or post fix? thanx

 

That is POST fix, I need to buy a 2010 module so I can work more with my hardware supplier to get the 6 speed stuff up and running, right now it is only 8 speed.

 

Great question, I'd have to dig into it more to see

 

that's the thing, I don't see/find any earlier version...

 

On a side note. My DPF light came on today. I believe that the pre fix TCU tune that I installed shifts at a lower RPM and subsequently allows the DPF to accumulate soot. To resolve the problem I had to run the Touareg at an RPM higher then 2700 while maintaining a speed of higher then 40 KMH. So I took it out for a blast on the highway and had to keep the the trans in 6th gear and 15 mins later the DPF light turned off. I continued for another 15 mins in the DPF clean out configuration to give it a good clean.

 

That has to be the worlds fastest DPF clogging in history LOL You've had the tuned tcm for what 3 weeks?
As with any diesel frequent spirited runs are always recommended to keep things clean.
