Conversely, a worn turbo will typically show itself through a noticeable loss of power, an unusual whistling noise under the bonnet, or abnormal oil consumption. Fitting a new turbo compatible with reference 49477-02407 restores the original driving feel that makes this sporty saloon and coupé so rewarding.\u003c\/p\u003e\u003ch2\u003eCompatibility of the new turbo with the BMW Série 4\u003c\/h2\u003e\u003cp\u003eThis new turbo is compatible with the 420i, 428i xDrive, 430i and 430i xDrive petrol variants of the BMW Série 4, fitted with the B48B20 engine with a capacity of 1998 cm³. Before placing an order, we strongly recommend checking the reference printed on the old turbo fitted to your vehicle to confirm exact compatibility with your engine code.\u003c\/p\u003e\u003ch2\u003eEquivalent references\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e49477-02401\u003c\/li\u003e\n\u003cli\u003e49477-02402\u003c\/li\u003e\n\u003cli\u003e49477-02403\u003c\/li\u003e\n\u003cli\u003e49477-02407\u003c\/li\u003e\n\u003cli\u003e49477-02410\u003c\/li\u003e\n\u003cli\u003e49477-02411\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eExchange basis and warranty for this BMW Série 4 turbo\u003c\/h2\u003e\u003cp\u003eThis new turbo is sold on an exchange basis: in accordance with our Terms and Conditions, return of the old turbo is required, but it is only collected after the new turbo has been delivered and fitted, so your BMW Série 4 is never left off the road.

A cracked intercooler or a poorly secured hose can also cause a loss of boost pressure that is harmful to the turbo's operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCheck the condition of the oil circuit and replace the filter before fitting\u003c\/li\u003e\n\u003cli\u003eCheck the hoses and hose clips for leaks\u003c\/li\u003e\n\u003cli\u003eInspect the air intake and intercooler to rule out any leaks\u003c\/li\u003e\n\u003cli\u003ePrime the turbo with oil before first start-up\u003c\/li\u003e\n\u003cli\u003eDrive gently during the first few kilometres after installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThis same turbo also fits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/en\/products\/new-turbo-bmw-serie-1-49477-02407\"\u003eNew BMW Série 1 Turbo – Ref. 49477-02407\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en\/products\/new-turbo-bmw-serie-2-49477-02407\"\u003eNew BMW Série 2 Turbo – Ref. 49477-02407\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en\/products\/new-turbo-bmw-serie-3-49477-02407\"\u003eNew BMW Série 3 Turbo – Ref. 49477-02407\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":46255345631317,"sku":"4947702407_TURBO","price":544.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0656\/9161\/5317\/files\/turbo-echange-standard_b940d142-c4b5-4001-99d5-088eaea80e7a.png?v=1790813758","url":"https:\/\/eden-boites.com\/en\/products\/new-turbo-bmw-serie-4-49477-02407","provider":"EDEN BOITES","version":"1.0","type":"link"}
