Is that the one that runs under the front of the car? OEM one from TPS isn't that expensive iirc, think I paid about £55.

Yes it is but I remember replacing it with just one braided hose or something similar that was about a quarter of the length and flexible. Also I do not have a TPS near me.

 

It's the cooler pipe, surely change it with a proper cooler pipe.

 

Found a picture of what I mean and used years ago on a previous TT.

Surely you didn't replace the cooler pipe with a short length of flexi hose?

OMG.....!!

Yes the cooler pipe is needed to cool the power steering fluid, it gets hot, some cars even have proper cooler rads for the power steering fluid.

 

My one started leaking so
my son who works with hydraulics kindly made me up a hydraulic flexi pipe ages ago

Works perfect and alot tidier too

worth paying a bit extra for the right part

 

For that sort of money I'd stick with the standard setup.

 

I think the quick rack high pressure pipe gets to 1000psi, hence the need for a cooling circuit. Also if the pipe is not the same size as designed it won't have as much fluid in either.

 

The hydraulics need a certain amount of fluid in the system to work properly and especially to keep the circuit cool and to avoid overheating and that's why the pipe work snakes about all over the engine bay holding the fluid volume that it needs, if you used a short length of pipe then that holds less fluid and so the system will have been overheating and eventually given up the ghost, it's good to use hydraulic hose but should be of a similair length to keep the fluid volume approx the same.

Also, the cooling loop is metal to radiate heat.
A long rubber hose won't do the same job.

 

If my pipe fails I will probably take it into work, flush with degreasant and sweat a repair patch over it with silver solder. If its only 1000psi it should be an easy fix.

 

I just bought a second hand one for 25 quid, the high pressure pipes are more expensive that the cooler pipes.

 

mine leaked, I just bought a replacement from audi, because MASSIVE PRESSURE!!!!

 

If I remember right, this is the one that runs round the front of the car, then runs right up the side of the turbo?

Fantastic idea for keeping the oil cool.

It's the return hose, so, like, no pressure in it.

I bought a banjo hose fitting and 3m of LP hose from the local hydraulic shop. Routed the hose round the top of the engine bay at the front and back to the reservoir. Been that way for 3 years now with no issues.

Yes the cooler pipe runs across the front of the car, but the turbo is behind the engine at the back, so about as far away as it could be!!

Rubber is a good insulator, so won't provide much, if any, cooling.

Some cars have a coil of metal pipe, some have a proper little rad, but they all have some form of cooling for the power steering.
Replacing that cooling unit with rubber pipe is not a good idea.

 

No, rubber isn't good.

But the pipe runs round the front of the engine, then back to the rear of the engine bay before passing up the side of the turbo.

My routing keeps the return line away from most of the hot parts, and is a lot cheaper than audi want.

I'd lay even money on my setup running as cool as the original, or cooler.

 

Mine failed last year, think it was about £345 from audi not even stainless steel..
But if its a safety issue by obviously providing cooling, and its the wife's car, so we had it done at indy.

It was more expensive than that :-

I remember discussing this with my mechanic and he told me he had a replacement part made in a specialist shop; its the shops that can also make custom radiators and/or aircon hoses. You just need to give them the old one to make one with similar bends.

No idea about the cost in the UK though.

No offence but if you paid that for power steering cooling pipe you have more money than sense!

 

I'm breaking a 225 - which pipe do you want?

I think I did have, till I bought a mk1 TT, now the money's going and my sense with it :lol:

 

Sorry but for what its worth why on earth would you try to 'bodge' a repair, put your hand in your pocket and buy the correct replacement part, I cant understand why people buy these cars and continually moan about the cost of OEM parts, if you cant afford them then maybe get another car?
