DRC: While you’re in there jobs

Post by MapleSyrupJizz » Thu Mar 04, 2021 9:57 pm

Hi all,

I’m getting the DRC overhauled before the car comes back on the road on the summer. This is all shocks, flexi hoses, hard lines, the lot.

I understand the hardlines are a big job and lots of stuff needs to come down to cater to get this done. Especially in the rear.

What I’m asking while all that work is getting done are there any “while you’re in there” jobs that are worth doing?

Any help greatly appreciated.

Thanks
B

Rear subframe needs dropped and the fuel tank lowered.

See how bad any corrosion is and fix it. Subframe will likely need to be refurbished (blasted, zinc coat primer and then epoxy painted) with new bushes.

Fuel filter may as well get changed at the same time. Diff mounts etc.

This is my next job, replace the entire DRC system (currently on coilovers), new brake lines and everything else underneath that needs doing!

Probably better doing now before the DRC parts are no long available....

Hope you don't need the central control valves, they are not cheap!

Yeah that’s my thinking. Get it all sorted while parts are available. I have front shocks, all flexis and hard pipes. Just need rear shocks.

Fuel filter has been done not too long before it went into the shed for winter. I wanted to put braided hoses for the brakes on but the hard lines were quite bad so I’ll be doing them too. Are the fronts tricky?

Half thinking of buying a 2nd hand subframe (there’s one I know of in Germany) and prepping that an doing a swap

Thanks a mill for the info. Pretty much confirmed my thinking.

Let’s hope the valves are good now.

Iirc the engine has to be slightly lowered to access the front brake line. I fitted braided lines to mine and the rear hard lines were pretty corroded at the joints to the flexis. There was no way they were coming undone so I cut them off at a straight run and flared both ends and put a joint in similar to the ones at the front left wheel housing . Brought a nifty flaring tool which let's you do it in situ and you cant go wrong with it .
Can echo what has been said about corrosion on parts of the underbody .Shocking really how under protected it is in some places .. Apply Bilt Hamber products and they should see you well .

There's central valves going for a good price on ebay from the US. I bought two and no drama, parts arrived quite quickly. I have to be honest and say I've not opened the box yet to have a look at them

Yes same thing has happened me and the guys working on it have suggested what you have said (if I'm understanding them correctly). Thanks for the info!

Thanks for that. I've seen a few central valves for sales on ebay at not too bad a price. Is there any way of telling if they're still OK or not?

I bought 3 from the seller listed above. All brand new so should be fine once installed. They are genuine Audi parts so exactly what you would receive from a dealer parts department.
