The BMW M2 Competition needs its own scanner guide. Its S55 engine and associated equipment make it a different buying question from the original N55 M2, even though both cars are called F87. A basic engine reader can be useful, but BMW-aware access matters when your concern involves chassis electronics, the rear differential or M DCT.
This is a documentary buying guide. Unusual Cars has not independently tested this vehicle, scanner or function. Exact access varies by build, controller, vehicle software, interface and tool version.

Quick scanner choice
| What you want to investigate | A sensible route | Confirm before buying |
|---|---|---|
| Engine light and emissions codes | Generic EOBD reader for the first report | Engine baseline; save codes and freeze-frame information |
| S55 BMW fault detail | BMW-aware handheld or supported phone setup | Exact S55 engine fault memory and supporting information |
| DSC, differential or M DCT warning | Confirmed access to the fitted BMW controllers | Named module coverage, not simply “F87 compatible” |
| Guided investigation or software work | BMW specialist using legitimate software | Scope of the report and any separately authorised workshop work |
Three checks before buying
Which M2 Competition does this guide cover?
This guide covers UK rear-wheel-drive F87 M2 Competition fixed-roof Coupés in the selected 2018–2021 production range. The engine is the 3.0-litre S55 twin-turbo straight-six, with a factory six-speed manual or seven-speed M DCT as fitted. See BMW UK M2 Competition introduction and BMW M2 Competition S55 specification.
The original N55 M2, M2 CS, later G87, imports, engine swaps and materially altered electronics or emissions hardware are excluded. Confirm the production date and original specification around the 2018 change. A registration year, facelift description or replacement badge is not enough to identify the engine.
The UK Competition arrived in 2018; the American launch material uses a 2019 model-year label. Those labels should not be mixed up. BMW’s BMW F87 generation production retrospective records the F87 generation through 2021, but an individual car still needs a build check. This guide does not guarantee identical controller software throughout the range.
What a generic OBD2 reader can tell you
Generic EOBD provides the supported engine-emissions baseline: trouble codes, readiness information and basic engine data. It does not establish access to separate BMW stability-control, differential, transmission or body reports. See Gendan EOBD engine tools. The connector fitting the socket does not establish what the tool can read.
For an engine warning, save the full code, description and any available freeze-frame information. A generic report may supply a useful starting point. For a chassis or transmission warning, ask which relevant controller was actually reached rather than treating a clear engine report as a clear whole-car report.
Good evidence includes the original report and the complaint together. Record the dashboard wording, mileage and when the warning appeared. If a controller could not be read, retain that limitation. “No codes” and “module not accessed” are different findings.
An early Competition fault pattern worth preserving
BMW’s BMW SI B12 23 19 July 2019 includes F87 cars with the S55 among the listed engines, produced through 28 February 2019. It describes 160001 or 160020 for a missing or implausible crankshaft signal, occurring with 11A002 for low high-pressure-fuel plausibility. Catalyst-efficiency entries 180001 or 180101 may accompany the pattern.
The important point is the combination of entries and their recorded circumstances. A report reduced to “fuel pressure low” can hide useful context. Ask whether the proposed tool reads the complete BMW engine fault memory and supporting event information for your S55 build.
This is not a diagnosis of every M2 Competition, a reason to replace a fuel pump from one code, or proof of a UK recall or warranty entitlement. The bulletin has a defined production limit and describes a workshop investigation. Its repair and programming procedures are outside this owner buying guide.
Do not carry across the M3/M4 cooling-pump software bulletin simply because those cars also use an S55. A model or engine family match must be checked against the actual document. The original N55 M2’s historical differential action likewise does not automatically apply to a Competition.
Cooling and emissions: identify the fitted arrangement
BMW documents changes to the Competition’s cooling and oil-supply arrangements in BMW UK M2 Competition introduction and BMW M2 Competition EU emissions and cooling description. That supports treating it separately from the original M2. It does not establish that a particular coolant-loss complaint has one common cause or will always store a fault.
If coolant loss is your concern, describe which warning or observation prompted it and keep the complete scan. Ask the workshop to investigate the relevant physical system as well as the electronic evidence. A supported temperature value is information; it does not certify every cooler, hose or connection.
BMW also describes an Otto particulate filter, or OPF, for relevant EU markets in BMW M2 Competition EU emissions and cooling description. Check the car’s actual emissions equipment. Do not use an overseas listing or an altered exhaust as proof of the original UK arrangement. An app’s advertised diesel DPF regeneration feature is not evidence of a supported petrol-filter command on this M2.
For purchasing, name the fault report or data value you want. This guide does not promise OPF tests, regeneration, coding, exhaust changes or coolant-system commands. Product menus and factory equipment vary, and reading a report remains distinct from carrying out a repair.
DSC and Active M Differential need separate coverage
The Competition has revised BMW stability-control and Active M Differential settings, documented in BMW UK M2 Competition introduction and BMW M2 Competition EU emissions and cooling description. These chassis questions sit beyond a generic engine-emissions scan. Ask the supplier about the actual DSC and differential controllers in your car.
Request fault-memory coverage first. If a named live value matters, ask about that value separately. “Supports BMW ABS” is not a complete answer to a differential-controller question, and “all systems” should be backed by an exact model and function response.
Keep the engine and relevant chassis reports together. An entry in another controller can add context without proving that the second unit has failed. Equally, a code-free electronic report does not certify the mechanical condition of the differential or suspension.
Manual or seven-speed M DCT?
The factory manual and optional M DCT arrangements are established by BMW UK M2 Competition introduction. M DCT is not the ZF eight-speed automatic used in many ordinary BMWs. A product’s advertised 8HP data or adaptations should not be assumed to transfer.
For an M DCT warning, ask whether the exact tool and current software read the fitted gearbox’s fault memory. Request confirmation of any desired temperature or other readout separately. This guide does not guarantee clutch learning, adaptations, active tests or programming.
On a factory manual car, do not buy expecting an M DCT report. A clear scan also cannot certify the clutch, flywheel or internal gearbox. Use diagnostic information alongside the symptom and appropriate mechanical assessment.
A BMW-aware handheld: the standalone option
The iCarsoft BMM V3.0 documentation presents the iCarsoft BMM V3.0 as a BMW-focused handheld with broad E/F coverage and advertised lifetime updates through a PC/card reader. That makes it a candidate to verify, rather than an exact S55/M DCT/controller guarantee.
Ask the seller: “Can this exact model and current software read engine, DSC, Active M Differential and fitted M DCT fault memory on my UK M2 Competition?” Give the build date and remove M DCT for a manual. Ask separately about the data and report-saving options you need.
Our iCarsoft BMM V3.0 buying guide explains the package checks. The Amazon search is a comparison route; results can include different generations and multi-brand devices. Keep the supplier’s coverage answer and check the exact item before ordering.
BimmerLink and its adapter are separate purchases
BimmerLink supported vehicles lists the M2 family from 2013. A supported interface and paid full app are separate purchases. The UniCarScan UCSI-2100 UK package is a Bluetooth LE candidate listed for iOS/Android; check Developer adapter selector linked by BimmerLink. The UK BimmerLink listing and release history currently requires iOS 15 or later.
That supports investigating a BimmerLink route for this F87. It does not establish every differential or M DCT readout. Ask about the actual modules and data you want, using the S55 Competition specification rather than simply “BMW M2”.

OBDeleven and the BMW workshop route
OBDeleven vehicle support includes BMW F-series cars. Supported diagnostics use an eligible NextGen 2 or OBDeleven 3, the BMW-capable app and the FREE plan. Optional apps/Credits are separate; PRO manual coding and adaptations are VAG-specific. See OBDeleven Advanced Diagnostics and OBDeleven licence terms.
For a guided investigation beyond a consumer report, BMW AOS is the legitimate BMW workshop route. Current vehicle coverage, entitlement, Windows and interface requirements apply; see BMW AOS technical requirements. A reader or arbitrary Bluetooth adapter does not establish a working programming setup.
Buy the capability you need to gather evidence. If a workshop proposes software work, ask which documented issue or verified finding it addresses. The ability to display a BMW code is not the same as the ability to carry out its remedy.
Before ordering or buying a used Competition
Identify the engine, production date, gearbox, phone if relevant and known software or hardware changes. Write down the systems you need to read, then compare confirmed packages. Extra service icons or subscriptions do not compensate for missing coverage of the controller behind your warning.
For a used car, combine the scan with service history and an appropriate inspection. Recently cleared memory, incomplete module access and unexplained modifications should remain visible in the evidence. A clear scan cannot certify engine internals, the crank hub or the entire cooling system.
Common questions
Can I use the original M2 scanner guide?
Its N55 vehicle scope differs. Use this Competition guide and confirm the S55 build, installed controllers and gearbox before buying.
Does 11A002 prove a failed high-pressure fuel pump?
No. Preserve the complete code pattern and recorded conditions. BMW’s early-car bulletin describes why associated crankshaft and catalyst entries matter.
Can a generic reader see any useful S55 faults?
Yes, supported engine-emissions codes can be useful. That does not establish BMW chassis or M DCT access, or the full manufacturer-specific report.
Is the M2 CS covered?
No. This guide covers ordinary M2 Competition cars. CS, G87 and materially modified arrangements remain separate scopes.
