Hello

I decide to sell my a6 c6 3.2 fsi quattro estate and looking for a A8

At the moment I'm not sure if I want to spent the budget for a d4 may I go for a late d3.is there any tip what to look for by an 4.2tdi or 4.2fsi I prefer to go for a fsi but they're quite rare on the market.I've read that on early 4.2tdi they have used a lot of plastic guides which get quickly worn and can occur a lot engine issues.May there are also air suspension faults? 

Thanks jean

 

 

 

 

Regardless of engine service history is key. Either car should have had a Cambelt and water pump change. Also check that the Audi gearbox has been serviced. 

In addition, make sure that the quattro system has been serviced and that the tyre tread is even on tyres on the same axle. As uneven tyre wear can damage the quattro system. 

Air suspension can fail and the compressors or bags aren't cheap. Also make sure all electrical items work as most components such as AC compressors etc can be expensive to replace. 

I'd also recommend looking at buyers guides on YouTube
