Hello there, I'm new to this forum and just seeking a bit of advice if possible.

I've recently bought myself an A4 Avant, P reg 1.9 tdi 110 (294000 miles on the clock!). It's only my second car ever and my first Audi and diesel and I'm a bit lost when it comes to poking around!

It's got a number of problems I'm discovering and I'm just wondering where to start?

First off: every morning I drive up a big hill in 3rd gear and just as I hit about 2500 revs the engine drops off power. If I keep my foot down it comes back, then goes and comes back and then by the time I'm at the top of the hill it's gone again. I can switch the engine off and on and the power will be back but sometimes it will go again if I put the foot down. Turbo? Fuel delivery? It's quite annoying but maybe not my biggest issue.

Secondly, I was looking underneath the other day and noticed right under the driver's seat, what I think is a bit of suspension was all shiny. I gave it a dab with a baby wipe and aside from the normal grot it had a bit of a white-wine tinge to it. I'm hoping it was only diesel rather than brake fluid (neither good, I know)?!! There are two pipes running along the length of the car where I saw it glistening so it could be from those but I can't seem to follow them far enough to figure out what they are and my Haynes manual doesn't give me any more detail!

What else?

The Exhaust is hanging off and resting on the rear axle. Should I get a new bit welded on to hang it? There's just enough of the Hanger to get some garden wire around it maybe but I thought this might make the pipe rusty?

Oh yes, and for some reason the steering wheel is on at about 30 degrees clockwise to central! Someone mentioned it might be the tracking is out but would it make it that far off? It's a bit distracting but not unliveable with.

Power steering fluid leak too but I'm just topping it up until I can decide what the most important things to deal with first are.

I'm hoping to keep repairs to an absolute minimum with home bodges if possible but if I need to bite the bullet then you can be as frank as you like with me!!

Any help very much appreciated!!
