Hi bo, i got my 335 in june dis yr. V r lucky becoz d e92 shares a lot of common parts with e90. Fyi i serviced my car over d weekend n d cost is as follows; Plugs x 6 rm330, atf rm520,atf oil sump with filter rm375,engine oil 10w-60 rm430, oil filter rm55, workmanship inc resetting n deleting fault codes n workmanship rm 280. I also replaced 4 new bilstein adjustable absorbers 4 approx 4.5k. N i pump shell racing, so no issues with hpfp n turbo. Dont use 95, d high compression n54 wont like it n 98 ron though expensive is worth d extra cost. D 335 is an amazing car, n u will enjoy d car 4 many years. Hpfp does not cost a lot 2 replace, but d turbos i read in another forum can last 100k km b4 they need replacement. This is a more expensive repair at betw 12 n 15k. 50 liters of petrol will cover close 2 400kms. Road tax is about 2k per annum. Tyres rear 275/30/19 cost approx rm1300 each. Front 245/35/19 approx rm900 each. Thats all i can think of. Gd luck in your hunt.
