Need your input

Hello,

I am looking at a 2013 35i with 84K a great service history. Oil changes is pretty regular as stated in carfax. Water pump and thermostat was replaced at 56K and valve cover at 86k. No other mention of any mechanicals besides the WP and Thermostat.

At this age and miles, in your experience, how are are the turbos? Are they pretty robust granted oil changes were regular? This will be my first turbo BMW. I had e53 3.0, currently a e83 x3 and a 201 328i that are all NA and so far they are pretty solid.

I appreciate any input you may have.... OR should look the other way.

I bought 2011 with 145k. It's at 193 now.

I had to replace those same and also the turbo control solenoid.

My Valvetronic motor has failed but I didn't replace it yet. Not a terrible job but will take me a couple days and needs a special tool to rnr the injectors. Fortunately BMW programmed in a backup that'll run ok just very rough idle when cold.

We also bought n55 based f10 535 with about 70k i think it's up to about 110. Had a coil fail on that recently. It's prob a good idea to have a spare on hand so you can use a good brand vs whatever auto zone has.

I'm in bad need of intake walnut blast but no issues with the turbo (single)
