Another Angle on Torque Converter 17125 Code

[RS6Steve]

Bam, there is a thread on hear already about that somewhere, they will only do the valve body here!

I thought it was familiar, I wrote that comment about ZF UK will not upgrade components etc. What I meant was, the ZF UK partners:

ZF UK do not perform servicing or sell parts (other than full remanufactured gearboxes) to the public in the UK, however, the outlets of ZF Germany will perform these services. ZF UK have servicing partners that have access to all of the ZF parts and knowledge base. I was told these are the better ZF partners:
JP automatics – 0845 130 4754 (Bristol)
Sussex Autos – 0132 384 886

I hope this helps.

Sussex Autos seem to rebuild TCs and are ZF UK partners but they make no mention of VB rebuilds/upratings. I'll be giving them a call soon, when I get the time... or someone else can take up the slack innit.

Luke, are you a manager at work? You try and palm everything off !!

lol - good call.
I'm actually one of the directors but I usually do almost everything myself as I've moved into a highly audited role, these days I can only try and remember what it's like to palm things off. Also, I don't have an urgent timeline on this topic like some other people might do.

Hello Luke

Thanks for your enquiry.

I believe the transmission you have in your Audi is a ZF 5HP19 box. If this is the case, we can raise stall speeds of the converter in most instances, depending on which converter is used in your box. We do not rebuild the gearboxes or anything at this company.
If we are able to raise the stall in you converter, we would not be able to tell you how much we can raise it by. It would simply be higher.
The other thing you may want to bear in mind, is that the converters are notoriously poor in that gearbox. We often do standard rebuilds on them, and most of the time the clutch plates are torn apart inside. So, by putting more power through it, you could end up damaging the converter quite frequently.
Also, we would not offer a warranty on this converter, as it would not be fitted to an ‘un-modified’ vehicle.

I’m sorry if this not the kind of information you wanted to hear.

[Cost]

The cost of rebuilding the converter would be £197.50. We can have a courier collect your unit from you at no extra cost, if this would be of any help to you.

[Valve body]

We don’t rebuild Valvebodies on site, however, we do have a company that can do them for us.
I have spoken with them about rebuilding or uprating your Valvebody.
They say the only way of really uprating that Valvebody is to increase the pressure. But this could lead to hard shifts etc. Short of that, they may be able to fit a shift correction pack to it, but whether it would actually change the performance of the unit is doubtful.
For a straight rebuild of this unit it would be £295. If you did want to try it with the correction pack it would be £375.

Shoppinit or Snoopra (or anyone else who may know) - what Valve Body and TC mods would be ideal to make said items more resilient? Whilst keeping drivability, of course.

[Shoppinit]

It's not a 5HP19, it's a 5HP24A. Bit worrying that he doesn't know which box goes in the RS6.

I'm not certain, but I think the stall speed is a bit irrelevant unless you intend to hold it on the brakes, rev the engine then release the brake, dragster style.

As for valve body, I haven't really seen any feedback about the mods, positive or not.

[bam_bam]

I agree on the stall speed, useless unless launching all the time. Will increase motorway RPMs too if I understand it correctly. I wasn't really interested in it, he just offered it as a mod.
I guess all this info would only be useful info if anyone wanted to get their VB or TC rebuilt. However, quality is yet untested from Sussex Autos.

Does not sound too promising so the USA would seem the best option for any tranny upgrades....

Not sure if this has been discussed previously - Question: would driving with a faulty/failing/failed Brake Light Switch (BLS) cause early wear and ultimate destruction of the Torque Converter (TC)?

I'm currently going through diagnosing a 17125 issue but I'm very sure the BLS is mostly to blame. So I couldn't help thinking about a correlation of GB or TC failures and issues with the BLS. If every time the '6 is driven and the BLS is throwing wrong info it means the TC is consistently overworked, ne?

My VAGCOM codes:

16955 - Brake Switch (F): Implausible Signal
P0571 - 008 - Implausible Signal - Intermittent
Readiness: 0000 0000

Replacement part number 1K2 945 511 RDW

2 Faults Found:
17125 - Torque Converter Clutch: Stuck OFF / No Power being transferred
P0741 - 35-10 - - - Intermittent
17087 - Brake Switch (F): Electrical Malfunction
P0703 - 35-10 - - - Intermittent

1 Fault Found:
01119 - Gear Recognition Signal
35-10 - - - Intermittent


Slightly off topic, I'm also having issues trying to upchange with the steering 'paddles'. There's no problem when going up through the gears via gear selector in Tiptronic mode, only when using the + paddle on the steering wheel. Any thoughts or methods of testing or replacement/fix?

[Shoppinit]

Sounds like the steering wheel buttons. Test with vagcom.

[bam_bam]

How do I test the switchgear (namely the steer wheel operated gear paddles) with VAGCOM?

[Shoppinit]

Not sure where I've seen them. Possibly the steering wheel module measuring blocks. Maybe the ECU or Tranny modules. It might be with the cruise control signals in the ECU, but you'll probably have to look through all of them until you find the tiptro buttons. Start with the Tranny module and look through the measuring blocks.

Hi,

I've been getting the 17125 error also, had it 3 times now in 1000 miles.

I'm pretty sure i'm going to have to fork out for a new GB. I dont use the 6 that often so test are few and far between.

For some reason I suspect my mapped tcu, no evidence, just gut feeling. I just think it might be trying to change gear too quick. Spoke to Doug @ mrc and he said only the paddle shift part is modified, so that quashed my theory, but i'll still test. My car is MRC mapped btw.

I did noticed the other week, that when I went out and gave it some only in Drive, I didn't get any errors.

I used my car again at the weekend and I have the error. The only difference is that I used sport mode and also the + paddle once.

I have no more error's apart from CD drive.

As I said, i'm sure it will be a new GB and i'm counting the pennies in my jar as I have no warrenty, but I might as well have some fun testing first.
