I've bought an Audi A4 yesterday, its from 2007 and the car is almost in perfect condition.
The only 2 things that are weird with it is that it is giving out a lot of black smoke. If the car is standing still, and i rev it, it will give out some black smoke for like half a second and then it will go back to normal (non-coloured, and not a lot of smoke either). The engine is a 2.0 TDI (BRE)
The second issue is that the steering wheel is a bit heavy, not extremely heavy, but heavy enough that is it a bit hard to move it with one hand. Could it be low power steering fluid?
And, another small one is that the Navigation screen isnt working. The owner said i just need to reconnect a wire.
Any ideas on what the issues would be?
