E82 · 2010–2013
In spring 2010 the 135i Coupé changes engine without changing power: the N55 replaces the N54 twin-turbo. For engine parts the code matters more than the badge; the March 2011 facelift keeps this engine.

2,979 cc straight-six which, according to BMW, combines TwinPower Turbo, High Precision Injection and VALVETRONIC for the first time; a single twin-scroll turbocharger. 225 kW at 5,800 rpm, 400 Nm from 1,200 to 5,000 rpm. New six-speed manual, or the seven-speed double-clutch gearbox (DKG) available from March 2010. BMW quotes 5.3 s and 8.5 l/100 km with the manual, 5.2 s with the DKG.
The sources consulted do not give the N55 oil change quantity: the TIS archive used (issue 12/2007) predates this engine. Have it read from BMW documentation using the VIN. Longlife-04 oils are approved for petrol engines only in the EU, Switzerland, Norway and Liechtenstein; outside that area, use the approval BMW specifies for the country.

The CBS calculates the oil due date from the fuel used; the sources consulted do not give the N55’s own starting value. The service content follows BMW’s list for petrol models built from 03/2007. At every oil service: oil and filter, handbrake check, microfilter. Every third oil service: air filter and spark plugs. Front and rear pads, brake fluid and the vehicle check each have their own service.
One twin-scroll turbocharger instead of two, an electronically controlled wastegate, VALVETRONIC, and solenoid injectors instead of the N54’s piezo injectors. Injectors, turbo and intake parts are therefore not interchangeable: order them by engine code. The timing drive is still a chain.

Reshaped front apron with Air Curtains, headlights with an accent strip across the top, L-shaped tail lights in an all-red housing, LED accents with the xenon headlights. ADAC lists the facelifted 135i Coupé from 03/2011 to 10/2013, still with the N55, 225 kW and 400 Nm.
Give the VIN so the exact oil quantity can be looked up. Count oil services since the last spark plugs and air filter, and say whether the car has the manual or the DKG.

CBS: starting value 25,000 km
The CBS calculates the due date from the fuel used: 25,000 km is only a starting value. From 09/2008 BMW encodes 30,000 km for several ECE petrol engines, including the N54; the list does not name the N52K.

Two separate services. Pads replaced, brake air ducts cleaned, discs checked (surface, thickness) and replaced below minimum thickness; at the rear the handbrake is checked too.
Source [10]At every oil service
With air conditioning: microfilter replaced at every oil service, per BMW’s operation list for petrol models built from 03/2007.
Source [9]Every third oil service
Replaced at every third oil service, so they follow the oil interval calculated by the CBS.
Source [9]Every third oil service
Filter element replaced at every third oil service; BMW asks for shorter intervals in dusty regions.
Source [9]Due date shown by the CBS
A separate service: brake fluid replaced, then the CBS display reset. The documents consulted for the Coupé and Convertible do not state the interval.

Diagnostic brief test, lights and horn, seat belts, wipers, corrosion, tyres (spare included) and Run Flat Indicator initialisation, battery, steering, coolant and washer levels, brake lines, underbody, steering components and a road test.

Yes: from March 2010 BMW offers the seven-speed double-clutch gearbox instead of the former six-speed automatic. With it the 135i Coupé does 0–100 km/h in 5.2 s at 8.5 l/100 km, less than the former automatic according to BMW.

No: the 2010 recall covers the twin-turbo six and the wastegate warranty extension names the N54. The N55 has a single turbo and is not listed.
It is not published in the sources consulted. Have it read from BMW documentation using the VIN rather than reusing the N54 figure.
AutoKarnet advice
No: ADAC still gives the N55, 225 kW and 400 Nm for the 135i Coupé from 03/2011 to 10/2013, with the six-speed manual or seven-speed DKG.
