Question for tuffty

[Asim1]

As it says this is for tuffty as I know it's something that he has done..anyone else feel free to also chime in. Basically I have a leak in power steering line the long one that come out from the side of the gearbox and snakes back around. After speaking to tj he mentioned you used rubber hose on yours. Mine seems to be leaking from the rubber hoses in between the steel so I need to get rid of the hoses and also the snaking metal piece. First question what size hose did you use..I need the internal diameter and also what type of hose. Thanks in advance.

small correction here... I have so far only replaced the 'cooler' pipe and extended the fluid feed to the pump....

However... you may want to be more specific as pretty much all the pipe works snakes to the rack over the box

So... hoses that leak are the flexi on the pipe coming off the pump... this leads to the 'snakey' bit in front of the box and then goes up the side of the box to the rack... this is the high pressure line so realistically its not an easy job to replace as you need high pressure flexi hose and crimpers to fit it to be sure of a safe fit...

The other favourites are the hoses that attach to the plastic side cover and go into the 'loop' pipe... this is low pressure side and I have replaced this pipe due to corrosion but not the hoses...

As for getting rid of the 'snakey' bits.... this is not the best idea tbh as the pipe work (in particular the 'loop' pipe) acts as a cooler... the rack and pipes are very close to the exhuast and on turbo cars that gets pretty hot and can boil the fluid making the steering feel notchy or worse case you lose power steering all together..

Sadly corrosion and leaks are common on this pipework and generally the only fix is to replace the lot from Audi... this is not cheap either...

You can (and people have) get pipes made up by specialist hydraulics places cheaply though and the 'snakey' pipe can have new hose grafted in assuming the rest of the pipework isn't a rotten mess...

I have pipework from a 4-motion to go in at some point which hasn't got the snakey pipe but I also have a PAS cooler to fit too that will compensate

i had the same problem so i got it replaced by a new one from audi, it was about 100 euros

Gonna have to start saving..luckily leak ain't to major.

They tend to 'weep' more than leak but the pipes take a bit of a hit especially as most car tend to run without the undertrays etc...

I think that's exactly what it is.. as I have heard scraping occasionally after going over bumps. Going to repair and be more careful.

More likely to hit the sump or subframe than the PAS pipework over bumps tbh... unless you use 1.8t PAS pipes on a VR6... then it just dangles it teasingly for the next speed bump to take out

Fair enough thinking to go shallow sump at some point aswell..I've seen some PAS lines on ebay for a tt so may grab them. As they dont seem to have the s3 tax on them

 

[<tuffty/>]

shallow sump is a bit pointless tbh... I believe the oil capacity is less... and you can still hit it... its just got a steel bottom rather than an alloy one...

You'd have to be pretty low to smack one tbh

Yeah it’s just floating at the minute a dread to think what they cost new , but that’s next weeks headache
