Are you sure you have a ZF? On this side of the pond we have the Aisin. What year?

 

its the latest generation Touareg CR 2019 launch edition..... it has the ZF

2019 VW Touareg UK Review Talks about Interior Quality, Slow Gearbox

The expression "you get what you paid for" doesn't apply that often to cars since some are overpriced and automakers have hidden agendas. But it seems to be true for the Volkswagen Touareg, according to this detailed UK review.

Yeah, you lost me (since we don't get EFF all over here).... but I would tend to agree with your thinking that this is simply a TCM programming issue, not a hardware issue.

 

Hi Bruce, I'm getting the same symptoms, but intermittently, but as you describe. I was thinking about starting a thread on that, but you beat me to it! Under harder acceleration it generally shifts smoothly. Generally tends to be smoother when everything warmed up too, but still present. I was wondering if it could have been uneven acceleration from the engine. Either way I'm thinking maybe a software issue too. I had mine serviced about 6 weeks ago and asked about any software updates for anything, but was told none other than the centre screen. I'm thinking about taking a demonstrator for a quick drive and running a scan with VCDS at the same time to check the software version in that to see if it's been updated!

 

@Malaudi Have you tried it in Sports or Manual mode ??? what is the result the same ?
I am based just round the corner near the EH Hotel.

 

Hi Malaudi, where are you based

 

Hi Bruce,
I'm on the north side of Brisbane. Bridgeman Downs. Hopefully you're not too far?

Warm regards,
Mal.

 

The "inbetween" gear you get is the torque converter unlocked, it then locks up.

 

I see, i had been thinking that it could possibly be that, i suspect there is some sort of lag in that operation. i have never felt that in any other cars for example Toyotas don't do that nor does the JLRs.

i assume some better calibration might address this then.

 

Do you actually feel it or just notice it because you re watching the tach? The Aisin box does this as well, it's not a new thing for manufactures to do.

 

I see, thats a shame as i am in Perth. The dealer was advising when a "field specialist" was going to be in Perth and have it look at the vehicle. so it would have been good to perhaps team up. i am also preparing a complaint to VW. if more people complain on here then i will be able to use this as leverage.

 

I could have sworn mine has an Aisin.

thanks for the trust @Blade74 , I'm still learning

the CR 8 speed gearbox or the OD5/ A8A is a zf box(8HP)
Refer volkswagen self study 584 for further information

for the few thousand kms I have driven the CR I couldnt fault the shifting.

What kms do you all have @Bruza005 @Malaudi @Steve104
if all three of you are experiencing the same issue then there's something to it. you could raise a ticket straight with vw australia
if i were to take a punt then I'd say its something to do with the mechatronic and its control unit.....hopefully a software upgrade will sort it out......

can someone try and switch off all assist systems in the menu and see if at all it makes any difference....

 

It’s a ZF sourced gearbox.

 

You can feel the jerkiness through the vehicle it’s shocking... like my VK trimatic

 

You have a VK? Noice.

 

I have the same issue. It doesn't appear on light acceleration, but in more brisk acceleration situations. Only in the bottom 3 gears and even then intermittently. I reported it to the dealer at first service and they couldn't replicate it (they said). They also said they were no software updates pending.

 

They wouldn’t have any updates because no one has complained but I will. Hopefully more get on here and raise the issue, then I can use a leverage.

 

I've got 20K on my CR. I'm not 100% convinced that it's just the transmission, as I feel the power delivery from the engine under light acceleration between about 1700 and 2000 RPM is a little erratic. I can manually hold the transmission in say 3rd and it feels slightly erratic under light acceleration through that RPM range.

 

Hi Singh, done some further googling....the mechatronic module seems consistent with the issues i am describing.

Do you know if the Amarok uses the same mechatronic module....the reason I ask is that it has the same gearbox...??

Hi Bruce,
Yep, from my understanding it's part of Touareg transmission you have.
Not sure if it's the same as the Rok though.
Call them on the customer service line.
Have you tried switching off all assistance features and test it?

 

hey Singh...

i will try all the assistance features and see if it helps, also there is apparently a gearbox reset ( AC on, accelerator pedal to the floor 15 sec, release, turn off). do you know if that procedure is the same for the CR model??

 

See how you go, keen to know if the associated electronics have any impact.
I was going to suggest that reset but don't think it's applicable to CR.
No harm in trying though

 

i will report back when i try those couple of things...

 

I have a 2019 CR launch edition and do get the occasional jerky shift. The car has only done about 11,000km, does do a bit of towing though.
I didn't think it was enough to warrant a trip to the dealer, I was just going to mention it at the first service.
Overall the shifting is very smooth, sounds like an adaptation issue.

 

I think @Singh set me on the right path.....

Doing some googling the adaptation issues is consistent with what I am experiencing


It’s going into the dealership to have the gearbox fully reset. will report back on how that goes.

 

See if they can share the scan, diagnosis report of the transmission

 

Hi Bruce, any feedback re the transmission reset?

 

I’ve had the gearbox and all adaptation reset, I can’t say that I am entirely happy there still are some jerky symptoms. It’s mainly at low throttle through the lower gears. I’m giving it some time before I address it formally. I am also going to see a repairing / rebuilder that is a ZF agent. I really think it’s this mechatronic which has a series of solenoids - might need some calibration tuning. There is a fair bit of complaints online regarding this issue but mainly from BMW owners who have the ZFs.

I will report back once I touch base with the ZF agent

 

Here is a Detailed View of ZF’s 8HP Automatic Transmission

The German gearbox supplier revealed the eight-speed automatic transmission in 2008, when it debuted on the F01 BMW 7 Series. Since then, it has become arguably the best automatic transmission out there, evolving into multiple versions and spawning into three generations, with the fourth set to...

Thanks for the update Bruce. I'm going to see what the VW Dealership here have to say about it, and also take a demonstrator for a test run to see if it's the same. I'll also try to do a scan at the same time to see if there's a different software version in it. I see there are a few reset options with VCDS in the transmission module, but having next to no idea of transmissions I'm reluctant to do anything I don't know about.

I'll report back too.

Regards,
Mal.

 

Thanks Mal, I think the resets in the VCDs is more likely going to be what I just got done, basically resetting all the adaptation to factory. That has helped to some extent but the symptoms very much still there...jerky and laggy.

I'm due to meet the dealer "Field Specialist" on the 17th so will see what they say. but i think this thing needs a software update of some sort in the mechatronic module.

Are you able to post any pics of what you are seeing in transmission module from your VCDS...I'm curious to see what settings there are.

Thanks Bruce.

 

Hi Bruce, I'll send some pics soon.

Cheers, Mal.
