What are the typical problems for my car?

Hey all I have a 2005 e63 645ci automatic with 70k miles. What are the typical problems that i could face in the future with this car? Like are there any specific parts that eventually go bad with this model? I'm asking because I don't want to deal with them in the future and would possibly trade my car in before dealin with them. thanks all!

We hope the best for our cars long term, but expect to replace the automatic transmission oil pan, Mechatronics sleeve, possible coolant pipe issue, replacing the coolant expansion tank, CCV valves. Not to be biased or anything, but it seems like 645Ci is more prone to issues than the 650i, but I could be wrong.

The coolant pipe usually fails in the 75 to 90k range. The valve cover & timing cover gaskets, & alternator o-ring, usually fail around 65k range. The expansion tank & bleeder line usually fail around 60k. The tranny pan & filter should be changed around the 50 to 60k range, Along with the Mechatronics Sleeve. These are the failure times & rough cost. Other items can pop up, but these are the big ones!

Coolant Pipe Indy cost 2k
Valve cover & timing cover gaskets Indy 800 to 1500.00
Expansion Pipe, coolant & bleeder pipe 300.00 Indy
Alternator O-ring Indy 800.00
Tranny pan, gasket, fluid & seal Indy 500.00

Yeah screw that I'm Tryna trade her in before I have to face those problens. I'm already at 70k. Thanks for the replies guys.

I had to top my coolant off twice this month. Im assuming this would have to do with the coolant piping? My cars at 71k

It could be leaking from another spot or it could be the dreaded expensive coolant pipe (weep hole and ring). If it is the coolant pipe, then check out this thread on the DIY sub-forum. Big Mike Brown in the Atlanta area (and I'm sure a few others) seem to have mastered the replacement of the coolant pipe with the German aftermarket expanding coolant pipe.
