Leak front right from bumper *fixed by doing Aux Rad delete*

[docurley]

Have not had time to look but anyone got any ideas it's coming from the front bumper drivers sise and smells like oil?

Oil cooler pipes.

[docurley]

Oil cooler pipes.

How much are the pipes or is it pipes and cooler?

[thedoluk]

oil or coolant might be aux rad.

[docurley]

Gonner have to get in there and figure it out might have to read about the aux delete option.

[flying_tomatoes]

as others have said, aux rad or oil cooler lines. the oil cooler line leak is pretty common in these cars

[coffey555]

If it smells like oil it is probably....... oil.

If it is oil you need to take care it does not let go when you are driving it.

Forge kit seems to be the way forward to prevent it happening again in another 4 years or take the proper precautions with the new OEM cooler and lines using Denso tape etc.

Aux Rad's are fairly cheap but cold air feed is a common mod.

I surprised that other then forge there is no alternative, at the end of the day it's oil pipes which should not be that expensive really and a simple oil cooler/rad.


need to see what the connections are for this setup and see what I can do I mean kit car builder do this all the time.

Doc,

I am not aware of anyone that has had their own hoses made up yet. It sounds straightforward but the space available where the hoses fit to the engine block is really limited and what I think has prevented anyone getting their own hoses made.

There are a few threads related to oil coolers and the Forge kit so it took me a little while to find it again. I'm not getting into a debate on the cost or value of the Forge kit but just posting this for info

Guys you are comparing apples to oranges here a little. Yes we could have put together a kit that uses the finest Chinese oil cooler, but we figured that an RS4 owner would want the best oil cooler we could use - which in this case is a Setrab Proline 19 row, retailing at £178 on its own. The braided lines are all dash 12 to match up with the oulets on the block, and yes unfortunately this means that the hose itself retails for about £30 per metre. Dash 12 hose ends are between £20 and £30 each of which there are four. There are a total of seven individually CNC'd components, of which one (the block outlet) took well over a week of R&D time to make the best flowing part we could in the minimal space allowed to us by Audi. Two of the parts had to be made from specially sourced nylon so that where it clips over the air con condensor, it doesnt scratch the paint off over time. Its this attention to detail that you would be missing from a slung together kit of ebay parts.
This is the best kit we could make, its not compromised by cost or design - it is what it is. It comes complete with full instructions, it will fit first time every time with no cutting or bending of other components, and doesnt have you scratching around in the garage for bolts because everything you need (bar oil) is in the box. It brings together tried and tested products from motorsport and combines them in a kit which means no more trips to Audi to replace your engine oil cooler every 5 years. All of our components carry a lifetime guarantee

Someone found another company and posted about them in a thread from a few days ago:

Yeah read that but on the grand scale of things still an expensive option for a relatively simple part but hay I knew this car would never be cheap to look after.

If it's the drivers side depending on the oil it could be the crimp connectors corroding. This is bad as they are the parts that can let go and dump all the oil very quickly.
The passenger side it is usually the solid right angle pipe.

In the absence of forge, you could go the JHM replacement lines in the faint hope the OEM Setrab cooler is ok and the joints/unions are unaffected at dismantle - still $495 (£300) plus import and shipping. Pound to dollar is 1.68 so it may work out cheaper...

I personally prefer this option as I like the idea of retaining the oil cooler in it's original position as opposed to raising this in front of the radiator...

Will take a look, I have a friends mate who brings back hot rods and cars from the states a few times a year so will find out when's his next shipment is due to leave.

It only works out cheaper if you use the original oil cooler. Pretty sure even if you can get the old one out it won't have many years left in it and you'll be changing that in a couple of years too. I'd rather bite the bullet and change the whole lot either the forge set-up which cost £2 less than OEM pipes and rad or JHM pipes and new OEM cooler. I figured the JHM pipes and new oil cooler option is still prone ot the same issue as the OEM solution unless you are very careful with the installation, so I opted for the Forge.
