I have read the tips and suggestions post in this forum and have a couple of more questions, please forgive me for my ignorance. I plan on having my 89K mile A6 serviced for the timing belt, fuel filter, trans fluid & filter changed, spark plugs/wires, and a leaking rear diff. serviced. Is there anything else that i might need to have looked at that i'm not aware of? The car has new brakes and tires already and the alignment seems fine. Before i purchased the car yesterday i was under the care while it was on the lift for almost an hour and i could not see any problems, other than a leaking rear diff. All the bushings looked good to me.

Lastly, is there a special make/model spark plug that this car requires?

Thank you for any input you can give, it is greatly appreciated.

 

CV Boot, tie rod ends, control arm bushings, control arms and how much did you pay for the car?

BTW it is a Bi-Turbo

 

Parralell twin turbo is the correct nomenclature. Bi-turbo is the marketing nomenclature.

 

Cabin air filter. You may want to purchase a K&N online and replace the air filter -- but be careful to ensure the K&N is well-drained so you don't get oil on your MAF and ruin it.

Make sure the TB job includes the tensioners, thermostat, and a water pump with metal impellors.
