BMW E90 3 Series 335i 335i
is it a safe used buy?

The performance-oriented E90 with the N54 twin-turbo six — genuinely exciting to drive, with a purchase decision that should hinge heavily on the fuel system check covered on the engine page.

How the engine fits this car

The E90's chassis handles the N54's power with real confidence, and this combination remains genuinely well regarded by enthusiasts — a large part of why so many examples have been tuned, which has its own implications for a used buyer.

Because this is a performance-focused trim, the used population includes a meaningfully higher proportion of modified cars than the 325i/330i covered elsewhere — worth keeping in mind alongside the fuel system check.

Pre-purchase checklist for this generation

Treat the HPFP and injector history check on the linked engine page as mandatory here — it matters more to this car's overall reliability than anything else.

Ask directly about tuning history, including any remap files, and have a specialist verify boost levels against factory spec if modification is suspected.

A hard cold start or hesitation under load should prompt a specialist fuel system diagnostic before you commit.
