The B48 engine on 320i (B48B20M1) & 330i (B48B20O1) are different (Pistons & Compressions Ratio), same case like N20 engine (20i & 28i)

Yes you can remap the engine after the warranty is expired, mine 520i tuned to Stage2+ with TCU...really superb

Concerned on M Sport fitted suspensions as most of the journalists critics on lack of Adaptive Suspensions on 330i models as the 330i ride is harsh especially on bad road surface

Sometimes i switch from Comfort to Sport whenever i cornering in high speed, rarely use Comfort+ unless the road conditions is not smooth

EDC per shock is estimated RM3,647 at SC & RM 2,800 at outside (Specialist Workshop)...parts price may diff as of today
4 pair change with labour around RM14k

Or you can retrofit with ST / KW suspensions and disable the EDC module (RM9k starting price for ST)

Or you go to Reiber Auto for EDC shock absorber reconditioning

EDC was my least concern, compared with Timing Chain Guide parts, rear EPB & Turbocharger unit

Yes, the B48 coolant issues was also mentioned during discussions with BMW Service Assistant during sending the car at SC,

timing chain has no issues for B48, luckily the Timing Chain positions for N20 is in front, no need to take out the engine from the body (estimated RM 1,500 to replace the chain & guide)

However, the most silly was everyone at SC discouraged to change Gearbox Oil, as there was a case - Gearbox became malfunction after replace the Oil & Pan, even one of my friends (Honda SC Mgr) experienced that, Gearbox became jerking & hesitate to change gear, trade in his F30 with new CR-V, mine ZF oil & pan changed at specialist, feels smooth & faster gearshift after service

I once was bising with the saleswoman at AB Kuala Lumpur about the gearbox oil change for ZF8HP Gearbox, even she didn't know about the Timing Chain Guide fiasco on N20, nevertheless she called a guy to discuss with me and happened the he is a BMW Genius Product Specialist.

He explained that the 'Lifetime' term was actually 5 years according to BMW standard and is not encourage owner to replace the Gearbox oil due to chance of Malfunction

Yes, it is true that you need to do a proper Gearbox adaptation after flush & fill of new GB Oil (ZF Lifeguard 8), provided with proper bleeding & topup the oil again shortly. (even the bolting sequence on Oil Pan must be correct)

I am very satisfied with the GB Oil change and next changes after 40k of mileage 😁👍🏼

P/S = 1 new unit ZF8HP at SC costing RM40k, Halfcut was RM4,500
