few things to look at for

Active steering fault - the sensor board itself kaput or the steering rack
Idrive electrical gremlin - if faulty probably the HU unit needs replacing. Need reprogramming
N52 HPFP - notorious for failing
N52 electronic water pump - Will definitely fail within 5-10 yrs old
Suspension bottoming out - worn shocks/struts
6speed ZF guibo flex disc and driveshaft - If flex disc fail, will get vibration at certain speed
ABS pump failure - this are expensive new. Consider refurbished units

All in all, RM10k only enough to replace broken parts, not include wear and tear item yet. Prepare at least RM25k to be save

It wasnt one single item but few that i changed over the course of 4 yr ownership of a e60 bmw 525i n52. You wont go wrong with this engine. Agree with others dont cheap out on the engine dept. If u want extra oomph, get a 320d but try avoid 2007-2012 model (timing chain issue). Bmw revised the chain design on later diesel model to solve timing chain failure

Active steering sensor recond - this one i think was rm1.5k

Abs pump repair - rm800 for the repair kit

I dont rmb the exact cost but the electronic water pump, thermostat+housing and coolant tank costed me like rm3k++ back in 2013

I also changed compressor refurbished and that was rm1k+ for parts alone. Changed the cabin cooling coil while i am at it servicing to save on labour, add another rm800

All the best with ur future UDM, ultimate driving machine. Head over bmwclubmalaysia forum, they have a spare part cost thread and u can get a feel of how much u would spend changing wear and tear parts
