The diesel 335d is so very different! Unbelievable how many more things are monitored, heated, etc.
DEF tank heating on the active resevoir
Heated fuel filter
Electric booster heater on the HVAC due to diesels taking longer to warm up.
16.5:1 compression ratio.
Many more switchover valves, filters, etc.
Forged Connecting Rods, closed deck and reinforced block and lower girdle.
Different Transmission, torque converter, rear end gear ratio, etc.
I'm really surprised the MSRP on a diesel is only around $3500 more than the gas equivalent.
