turbo hoses leaking oil?

    Hey, did my oil service yesterday on my A3 2.0 TDI SPORT 8p 54reg- noticed there was a bit of oil giving the occasional drip from the sump plug so bought a new plug for £1.50 and hopefully that's sorted that, I've only had the car about a month or so.

    Noticed while I was under there though that at both front corners there is oil leaking out of these hoses:

    [​IMG] - front passenger side

    [​IMG] - front drivers side.

    Assuming these are turbo hoses?

    Is it likely that I'll just be able to put new jubilee clips on to stop this?
    Could this be why I've got a slight hesitation on acceleration? (Forgive me if I sound stupid - I'm fine with general service and stuff but after that I need teaching ha ha).

    Thanks

    This is common. Needs, the clips undone, all oil residue cleaned off and degreased, then O ring re-seated or changed. As a precaution, I'd also use a liquid sealant (like Hydraulic sealant) to keep the hose from moving and leaking again.

    Excellent thanks, will do that. What are the hoses called? So I can get the correct O-Rings.

    Had the same problem on my 8l A3 TDI recently where there was a slight boost leak at the intercooler boost pipe. Bought a new o ring from the dealer, cleaned up the join, replaced the o ring and all's good. Easy job.

    Sounds like a simple job - don't suppose you know the part numbers for these O-Rings?
    Need to get myself a Haynes Manual..

    I don't sorry - yours will probably be slightly different as it's the newer shape A3. To do mine I just had a word with the dealer, he looked it up on the system and gave me a choice of 2 sizes - I measured my boost pipe to know which size I needed. Definitely get a Haynes - I use mine a lot.

    I would love to know this as well, passenger side is doing the same. Are they called boost pipes?

    Iv changed mine.

    Get your self down to your local audi dealer ship with you vin number.

    Ask for boost pipe seals. The parts guy at Carlisle audi printed a exploded drawing of of the whole boost pipe work for the bkd engine and I could pick and choose what seals I wanted as well as pipes (the lugs on my pipe where knackered too so kept blowing off).

    Here is a thread I started a while ago with pictures of the seals and pipes

    Thanks Jack I need to go to Audi today anyway really as when I bought the car it only had one key - tried to get them to program a second (second hand one) - and it's resulted in it saying safe on the dashboard with my key!! So will pop into parts when I'm there and get some seals for the boost pipes.

    Cheers :laugh:

    Got the two O-Rings from Audi, £3 a pop - will get that done tomorrow if it's a decent day.
