Default Going from 2005 A8L to 2007 A8L

I am thinking of going from a 182k 2005 A8L to a 85k 2007 A8L

Is there anything that I should know about that particular year to look for at that mileage? It has a chain, so a timing belt i am not concerned with.

I know that all the coils and spark plugs were just done as well as the injectors were just replaced with new ones.

So anyone with ideas of what to look for would be greatly appreciated.

Also, my 2005 runs like new pretty much. i keep the maintenance up! Just did a 180k and all 4 brakes and rotors.

It is throwing a couple codes p0171/p0174/p0491/p0492, but doesnt seem to be affecting the vehicle.

what do you think would be a good rate for that car private party?

You have a small hole in the Secondary Air Pump hose to the engine. It its the hose that goes from the pump in the airfilter box to the metal hard line on the back of the engine that feeds air in to the EGR system. It will not affect performance like you said. The line can get soft and mushy around the area of the back of the engine where it connects. I was able to snip the mushy part off mine and reattach it. I'll need to replace it sometime soon but I'll replace it with some suitably sized silicone hose instead of the overpriced one from Audi. It's an easy fix.

As far as the jump from the 05 to the 07, it's really up to you. We've got 208K on our 03 and it's still in excellent shape. I had a cam chain tensioner pad fail recently and I'm in the middle of replacing that and doing the timing belt since all that had to come off to replace it. I'd love to have a newer one but these things keep getting more and more complex. I know my wallet wouldn't support a newer one unless I can work on it myself.
