Hello fellow BMW enthusiasts.

I just purchased a used 2013 BMW 335i xdrive with 130k kms on it.

So far the car has worked well for me and I have done some modifications including:

-new VSRF chargepipe
- k&n air filter (oem housing)
- NPBoost 1 step colder sparks and new ignition coils.
-MHD stage 2 tune running 93octane.
-new oil.

I wanted to ask what things I should immediately replace as far as preventative maintenance in concerned?

You should be running an intercooler with stage 2 or higher tune.

You should be running a high flow or catless down pipe for stage 2 as well.

At 130KM, changing transmission and differential fluids would be recommended. If the brake fluid is 2 years or older, change it as well.

Glad to see that you are planning to replace the charge pipe.

MHD actually only requires IC for stage 2. stage 2+ on MHD requires both IC and DP. This differs from BM3 since MHD rates their "stages" differently, and MHD stage 2+ is really equal to BM3 stage 2.

To add to what you've already heard, since it's XDrive replace the front differential and Transfer Case fluids.

Check for oil leaks at front OFHG, back of valve cover gasket and oil pan gasket.

Get a service history on the VIN from a BMW dealer, check glove box for receipts and any maintenance history on carfax

thanks guys! much appreciated. and thanks for the trans oil recommendations.

regarding mhd stage 2 tune. i reached out to MHD a few months back, they said that running a stage 2 tune in my part of the world (ontario during winter) was acceptable for now untill summer arrives. also a catless downpipe wasnt critically necessary as far as exhaust burble is set to soft and duration less than 0.8 seconds.

check out the tune if you live in colder climates. also, i cant emphasize letting the car warm up to operating temp (90c-120c) before pushing it.

Datalog a 1st to top of 4th gear pull on the stage 2 tune with stock IC and you will see what i mean.
