Hi,

What power steering fluid should be put in the 2.6 cab?

I understand you should only really put the Audi green stuff in. What happens if you use anything else, ie the red stuff (which I understand is the same as auto-box fluid, and therefore cheaper)?

Can anyone advise please?

Many thanks.

Hi 26, Well acording to the learned ones under no circumstances should you mix the fluids, it will rot the seals and cause all sort of problems, same thing applies to dot 4 and dot 5 brake fluid, here's a snatch from 12v.org .........

The power steering system requires a special mineral hydraulic fluid, Audi part number G 002 000. This is Pentosin 11S, affectionately called 'green gold' because of its color (green) and price (high). To fill the power steering system, fill the reservoir to the 'MAX' mark on the dipstick (approx. 0.85 liters/28 oz), then with the wheels pointed straight ahead, start the engine and let it idle for approximately two minutes -- the power steering system will bleed itself, so watch the reservoir and when bubbles stop coming through the fluid, the system is bled. Top off the reservoir if necessary.

Thanks Bruce,

You have confirmed what I believed to be the case. A couple of months ago I had the PAS pressure pipes replaced by a local garage, chosen for me by my warranty company.

They have filled the system with the stuff they had in stock (red) and now I am being told that the big puddles on my garage floor are down to failure of the seals in the rack.

I think I will be on the phone to them in the morning!

Thanks again.

Derek.

Aaaargh !!!
Stupid SOB's, i've learnt not to do anything on my cab until i've consulted one of the 'Magnificent Seven', visit this site often enough and you'll know who they are, i love my Audi but i think some of the guys must have the 5 rings embroidered on their pillowcases Laughing

Looks like a replacement rack, ouch !!!!, that's gonna hurt big time, i bet the mechanics will draw short straws to see who's gonna get the pleasure of that little job Confused

Well spotted 'Rotorboy', good to see someones awake' !!

Here's some more info sure to keep this thread running ......

Pentosin CHF 11S Synthetic Hydraulic Fluid - Fully synthetic hydraulic fluid for steering and central hydraulic systems. This synthetic fluid is correct for many later models which specify synthetic fluid. Temperature range -40C to +130C. Should not be mixed with ATF fluids or other power steering fluids. ***Note - this is currently sold as part # G00200 by Audi/VW as of 1990, replacing Pentosin CHF7.1 The CHF11S is correct for Audi/VW 1990 and later models, while Audi/VW 1989 and earlier models can use either 7.1 or 11S although 11S is recommended. Audi/VW states that 7.1 and 11S can be mixed if necessary but we suggest draining and flushing the system if you are changing from 7.1 to 11S***

Pentosin CHF 7Pentosin CHF 7.1 Hydraulic Fluid - Special mineral based hydraulic fluid for use in power steering, central hydraulic and suspension level control systems. Should not be mixed with ATF or other fluids. Temperature range -40C to +100C. ***Note - this was sold as part # G00200 by Audi/VW through 1989. As of 1990 Audi/VW is selling Pentosin CHF11S as their part # G002000. 1989 and earlier models can use either although the 11S is recommended. Audi/VW states that 7.1 and 11S can be mixed if necessary but we suggest draining and flushing the system if you are changing from 7.1 to 11S***.1 Hydraulic Fluid - Special mineral based hydraulic fluid for use in power steering, central hydraulic and suspension level control systems. Although more expensive than standard power steering fluids it is worth it because of its' compatibility with original fluids and seals. Should not be used in cars calling for CHF11S fluid, nor should it be mixed with ATF fluids.

Bruce. Confused

And just to play devils advocate, here's a snatch from 'Audifans.com'

*Subject Re: Mineral Oil alternative to Brand name Pentosin - [Mobil DTE-13M is generally OK] I don't know about the Shell product(have done no analysis on that), but as for the Mobil DTE-13M, I(and some other interested listers and a not so interested engineer) recently did a little cross reference/ analysis of the specifications and referenced Marks engineering handbook, internet and other manuals for working fluids similar to and including Pentosin. I/we compared to Mobil-DTE-13M as well as tractor hydraulic(not as wide of a range), marine lower unit(not very close), and others. It was indeed difficult to find an off the shelf fluid with the viscosity range and working characteristics incl. boiling point, flash point(important!) that Pentosin has - it is indeed a high performance mineral oil.

However, Mobil-DTE-13M is very close! In addition to being very close in specification, I think those who have tried it(Mobil DTE-13M), including myself will vouch that it is a fine and far less expensive substitute. It really makes a lot of sense especially when you consider that a system flush to install a new rack will waste close to a gallon of the green gold, and you can get 5 gal of the DTE-13M for under $50.

The one downside I read from the specs, is the subfreezing operation characteristics are not as good, so take that into account if you live in arctic climates where the temps may go down to 20 below 0F. There may be some other subtleties, but in general, most will find the DTE- 13M will work as a fine substitute.

A happy ending to this sorry saga!!

Some time ago we got the garage (a local one appointed by our warranty company) to admit that they had been negligent in pouring ATF into our Audi's power steering system. After a lot of wailing and knashing of teeth they fitted a new rack and pump to the car.

Trouble is they used the cheapest, nastiest pattern parts they could lay their grubby little hands on and bodged it on to the car! The pump they fitted was so noisy it scared old ladies as you drove along!

After they fitted a 2nd duff pump (leaky and very noisy, and only gave us PAS when it felt like it) I got the hump and contacted the warranty company and relayed the whole tale to them.

They told me to take it to East Kent Audi to get an estimate to put it right. It now has a new Audi pump and rack, they also replaced all the other parts (too numerous to list) damaged by the previous monkees and the car is lovely to drive again. Best of all my warranty company paid the bill in full to them over the phone and are now in the process of deducting it from the next cheque they send to the other gagage, I believe the bill was somthing like 1700. Ouch!!

Full marks to East Kent Audi as well, they rang whilst it was in and asked if I would like the cam belt and tensioner replaced, no labour charge as it was already stripped out, I just paid fot the bits! I had it serviced as well, and the total bill to me was less than 200.00. And they lent me an A4 2.0TDi while they did the work. Marvellous.

Having had our summers open top motoring ruined by cretins in overalls we are now lapping up the sunshine (such as it is) with silent steering and no leaks.

Thanks to everyone who gave advice on this topic.

Derek.

I have read a lot about bleeding the system. I have used a hose to extract all of the fluid from the reservoir. Then I added the green gold. I used about half the bottle.

I want to get this right. How do I get the rest of the RED stuff out fo the rack and hoses?

Thanks,

Ralf

Should have got it all out first mate. Disconnect the lowest hose from the Brake pressure accumalater (Bomb), once its all out from that end the same on the rack feed hoses. It would also be a good opportunity to change the hoses and clips from the resovoir as they always leak there.
Citroen hydraulic mineral oil will suffice at a fraction of the cost.
Good luck Evil or Very Mad
