Hi,

So I recently purchased (~2 months ago) a 2010 BMW 335xi MT CPO. Has about ~97,000 km on it. I had it down to the shop recently to have it walnut blasted and to look at a rattle that got worse which resulted in me getting brand new turbo's next week.

I wanted to know what should I be looking to do next for maintenance? The main one that I am concerned about is the water pump. Should I have them replace at the same time as the turbo's? I would hate to be stranded.

Here are my records, not including hardware fixes:

Before I bought it:
30,000km - Sep 9, 2010 - Oil Change
47,900km - Feb 18, 2011 - Service Vehicle Check
47,900km - Feb 18, 2011 - New HPFP
61,000km - Aug 11, 2011 - Oil Change
69,600km - Dec 13, 2011 - Brake Fluid Change
69,600km - Dec 13, 2011 - AC Microfilter Service
69,600km - Dec 13, 2011 - Replace Battery

After I bought/getting the car ready for me to buy it:
96,000km - Aug 20, 2014 - Oil Change
96,000km - Aug 20, 2014 - Valve Cover
97,000km - Oct 10, 2014 - Walnut Blast

Next:
Waterpump and Thermostat
Spark plugs and coils - I plan to buy that amazing deal on Amazon and do-it-myself.
Brake fluid
AWD Transfer Case
Engine Drive Belts (V-belt and Serpentine)
Fuel Filter
Power Steering Fluid
Flush Coolant
Diff Fluid
Manual Gearbox Fluid

My next question is, I have a rough idle, that I just noticed now that it is getting cold out. I just notice it in the morning. It seems to jerk the car a bit while I drive for the first 5 minutes. Is this a leaky injector? Plugs and coils?

Appreciate it. I am pumped about having this car. So much fun.

got rough cold start exactly like how you described. car actually shake for a minute until engine gets warm and the problem go away. All i did to fix it was to regap my spark plugs to the right gap. If you haven't change your spark plugs...i would start with that since it's cheaper.

what's the correct gap for Bosche plugs on a N54?
