I have recently bought a 2004 S4 Manual 6 Speed.
It has a slightly notchy gear change from 1st to 2nd and less so from 2nd to 3rd.
This only happens when the car is cold.
As soon as it warms up it is absolutely perfect.
I was thinking of getting the gearbox oil changed.
Audi quote the following part no for the gearbox oil G052911A2.
I have seen references on other forums suggesting using a lower viscosity oil.
This would seem to be logical.
Has anyone any experience of doing this.
I have found references quoting G 052 171 A2 as an Audi low viscosity oil.
My local dealer cant find any references to this part number on their system.
Does anyone have the correct part number for this low viscosity oil.
Thanks in advance !!!!

Opie Oils will be able to recommend a suitable replacement/upgrade.

Mine is the same, performed a gearbox and diff oil change using the Audi oils. However the notchy change still remains, be aware that the gearbox and rear diff are different oil.

Next change I will speak to Opie and go for an aftermarket oil.

Thanks very much for that info.
I have emailed Opie and will let you know the result.
Out of curiosity has anyone heard of the Audi lower viscosity oil referred to elsewhere?
Thx in advance

I doubt it. laugh

All they ever do is spam post various car boards with the same article about engine oil. About 7-8 years ago I asked them on a BMW forum about gearbox oil. No reply. Which at first I put down to them not having been online. But 2 days later someone asked about engine oil and off they went again. So it occurs that they simply don't know.

Stopped buying from them after that. Went back to Mobil instead of the Motul 300V they'd recommended (Which is fundamentally a race oil anyway)

That *is* a part number for vw gear oil.

Odds are that the dealer are looking up parts in relation to your specific car, or (possibly) that they are looking up against Audi only, In my exp. some dealers can only access part numbers for the specific marque(s) they have a franchise for.

Fuchs show grades and equivalent part numbers here http://www.fuchs-europe.com/products/lubricants-mo...

Just stick to the oil the dealer says it needs. For the Golf MK5/MK6, enthusiasts have done a lot of testing and research and found the factory oil to be far better quality than aftermarket stuff.

Yes, for the 02M/02Q transverse 6 speed box. The S4 uses a completely different gearbox, ergo a different oil.

Having researched this further (And thanks Supercharged VR6 for pointing me in this direction) that the S4 gearbox is not the same as the gearbox fitted to other A4's.
I have been told that the lower end synchros fitted to the S4 gearbox are twice the size of those fitted on other boxes in order to deal with the extra power and torque.
As such I have been told it can take a little longer for the gears to transfer across until the oil warms up.
This appears to be a characteristic of the setup and I have been told a little mechanical sympathy is required until the box warms up.
If I take just a momentary pause when changing from 1-2 or 3-4 gears it is perfect even when cold.
I have been told that if anything terminal was wrong it would be more likely get worse as the gearbox heats up not better ?
The lower viscosity oil I mentioned earlier appears to be suitable for smaller engine A4 & A3's but not the S4.
I think I will replace the oil with the Oem oil and hopefully this should minimize it!!
Does this make sense ?
Dr G and Supercharged VR6 I would appreciate your opinions on this?

I ran a b6 s4 convertible for 18 months and my car was as you have described, a bit notch you initially but smooth once warmed up. I never had any issues with mine just the way it was, good car and fun with the roof down for the 3 days a year it was nice enough to do it.
