Checking the boost pressure, reading fault codes (power loss, under-boost, over-boost) and visually inspecting the turbo (shaft play, oil traces on the intake or exhaust side, abnormal whistling under acceleration) will confirm whether the part is genuinely at fault before committing to a replacement. On these twin-turbo engines, it is also worth checking the condition of the vacuum hoses and wastegate actuators, which frequently produce symptoms similar to a turbo failure.\u003c\/p\u003e\u003ch2\u003eA new turbo compatible with reference 49131-07171\u003c\/h2\u003e\u003cp\u003eThis new turbo is compatible with reference 49131-07171, used on the BMW Série 3 335i and 335xi (E90\/E91\/E92\/E93) powered by the 2979 cm³ petrol engines with engine codes N54 B30 A, N54 B30 B and N55 B30 A.

A clogged intercooler or a driving style characterised by hard acceleration without allowing the turbo to cool down (switching the engine off immediately after a spirited run) will also accelerate bearing wear.\u003c\/p\u003e\u003ch2\u003ePoints to check before fitting\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCleanliness and condition of the oil circuit (feed and return lines)\u003c\/li\u003e\n\u003cli\u003eCondition of the boost and vacuum hoses\u003c\/li\u003e\n\u003cli\u003eCleanliness of the air intake and associated filter\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWhen starting up, it is recommended to prime the oil circuit before the first engine start, to ensure immediate lubrication of the new turbo.\u003c\/p\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":46255034302549,"sku":"4913107171_TURBO","price":384.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/9161\/5317\/files\/turbo-echange-standard_ef4df325-f7f4-4c2b-ae86-7d0e4a4a65ee.png?v=1790810349","url":"https:\/\/eden-boites.com\/en\/products\/new-turbo-bmw-serie-3-335i-335xi-49131-07171","provider":"EDEN BOITES","version":"1.0","type":"link"}
