A BMW M5 E60 or E61 needs a scanner chosen for its S85 V10 and seven-speed SMG III. A basic reader may reveal an engine-emissions code while missing the gearbox or chassis report behind your warning. This generation also needs careful adapter checks, and the Touring adds equipment that the Saloon does not share.
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
| Your question | A sensible route | Confirm before purchasing |
|---|---|---|
| Engine light or emissions codes | Generic EOBD reader for a first look | Engine baseline only; preserve the original code |
| S85 or chassis warning | BMW-aware handheld or supported phone system | S85, DSC and EDC fault-memory access for the exact build |
| SMG warning or gear-selection complaint | Confirmed SMG III reporting or a specialist scan | Separate gearbox fault memory and any named live readouts |
| E61 rear-level or body complaint | Confirmed Touring-specific controller reporting | Actual fitted self-levelling/body equipment, not Saloon assumptions |
Three checks before buying
Which V10 M5s are covered?
This guide covers UK standard rear-wheel-drive E60 M5 four-door Saloons from 2005–2010 and E61 M5 five-door Tourings from 2007–2010. Both use the naturally aspirated 5.0-litre S85 V10 and factory seven-speed SMG III. See BMW 2010 V10 M5 production retrospective, BMW UK 2007 M5 Touring launch and archived BMW ST505 E60 M5 complete-vehicle training, archived.
Manual imports, conversions, other M5/M6 generations, race cars, engine swaps and materially altered electronics are excluded. Keep the production date and original specification with your enquiry. Imported or converted arrangements require their own compatibility confirmation.
The E60/E61 mainstream 5 Series guide has a different engine and transmission scope. Here, the shared S85/SMG III advice is followed by separate Touring equipment checks. A Saloon photograph illustrates the generation; it does not show the E61 or establish a UK gearbox specification.
Generic OBD2 still has a useful role
Generic EOBD can retrieve supported engine-emissions codes, readiness and basic engine information. It does not establish access to separate SMG III, stability-control, damping or Touring body reports. See Gendan EOBD engine tools.
An empty engine report is therefore not an answer to an SMG cog warning or EDC complaint. Ask which controller was actually scanned, and keep unavailable-module information with the report. A reader powering up is not proof that it communicated with the required system.
Save the exact code and description before looking up shortened explanations. A code identifies something the controller detected; it does not automatically identify the failed part. The same symptom can need electronic and mechanical investigation.
S85 throttle-actuator context: both banks matter
BMW’s BMW ST505 E60 M5 complete-vehicle training, archived describes bank-controlled S85 throttles and the MSS65 engine-management arrangement. The S85-specific Beisan S85 throttle-actuator component evidence lists P0638/2B15 for bank 1 and P0639/2B16 for bank 2, alongside BMW pre-drive and monitoring entries.
Some relevant P-codes can appear on a generic reader. It would be inaccurate to say all throttle-actuator faults are invisible to ordinary OBD2. BMW-aware access can add bank-specific wording and related report context; ask what the current product actually reads on your S85.
Retain the originating controller and bank description. A warning involving the engine and DSC does not, by itself, prove two failed units. Equally, a throttle-related code is not a guarantee that a replacement actuator or rebuild kit will solve the complaint.
This guide gives no actuator removal, rebuild or adaptation instructions, and no guaranteed failure mileage. For purchasing, ask about complete S85 fault-memory access first, then any particular value needed for the investigation.
SMG III is not SMG II or M DCT
BMW’s BMW ST505 E60 M5 complete-vehicle training, archived describes SMG III as a dedicated automated seven-speed Getrag arrangement. It differs from the E46 M3’s SMG II and from later M DCT. Its hydraulic pressure, temperature and clutch/selector-related inputs support a separate gearbox investigation.
Ask specifically whether the exact device and software read E60/E61 M5 SMG III fault memory. If you want hydraulic pressure, temperature or a position value, name it and obtain confirmation. The system having a sensor does not establish that every consumer tool displays its value.
“BMW automatic transmission support” is not a complete answer. Neither an eight-speed BMW feature nor an E46 adaptation menu establishes SMG III compatibility. A gearbox warning deserves the correct controller report before a parts decision.
A cog warning does not diagnose the pump
The SMG component supplier’s SMG Society SMG III component troubleshooting describes several possible reasons for the gear symbol, including hydraulic, clutch-actuation and position-information problems. It also lists 510E, 510D and 4FA0 as examples associated with clutch-position sensing or wiring.
Use those examples to understand why the complete report matters, not to order a component from an online description. A general warning does not prove that the hydraulic pump has failed, and a position-related entry is not proof of one replacement part.
A useful scan preserves the complete code, controller name, description and status. Confirmed supporting data can help a suitable specialist decide what to investigate. This guide does not provide pressure thresholds, powered testing, bleeding or adaptation procedures.
Shift feel and thermal protection need context
BMW’s training describes calculated clutch-overload protection that can alter shift behaviour and trigger a warning. That is another reason to retain the circumstances of a complaint; it does not mean every harsh shift is normal or that the transmission is healthy.
Record whether the symptom was intermittent, what warning appeared and what ordinary use preceded it. Ask the workshop to explain how the report relates to the complaint. Do not buy a tool assuming a generic “transmission reset” is the correct next action.
Clutch learning, gearbox adaptations, bleeding and software work are separate capabilities from reading faults. This guide makes no guarantee of those commands. If a repair has already been carried out, request the workshop’s follow-up findings and relevant records.
DSC, EDC and the differential arrangement
DSC is BMW’s stability-control system; EDC is electronic damper control. Both are distinct reporting questions from generic engine-emissions access. The M5’s documented chassis equipment is described in BMW 2010 V10 M5 production retrospective and BMW ST505 E60 M5 complete-vehicle training, archived.
Ask separately about the fitted DSC and EDC fault memory. A supplier’s “ABS support” label should not be assumed to cover damping. A chassis code can guide an investigation without measuring every damper’s physical condition or proving one sensor has failed.
The E60’s Variable M Differential Lock also should not inherit the later F10’s electronic Active M Differential buying checklist. BMW’s training describes its internal pump arrangement. For a physical differential noise, a clear chassis scan remains insufficient to certify mechanical condition.
E61 Touring: rear self-levelling and body checks
BMW’s BMW 2007 M5 Touring technical press pack documents rear air self-levelling, level sensing and compressor operation on the M5 Touring, alongside EDC and its tailgate equipment. These justify a separate E61 section; the shared engine and gearbox do not make every body or suspension question identical.
For a rear-level warning or related complaint, ask about the actual self-levelling controller’s fault memory. If a particular level value is required, confirm that separately. An EDC report is not automatically a complete rear-level-system report.
For a tailgate or other body complaint, identify the fitted equipment and ask which controller the tool can read. Do not assume every convenience option was fitted. A clear engine report does not investigate these systems, and a controller scan alone does not inspect every mechanical component.
This guide provides no suspension calibration, compressor commands or tailgate adjustment instructions. Confirm the exact E61 build and equipment before buying for one of those jobs.
BMW-aware handhelds and older interface support
The iCarsoft BMM V3.0 documentation advertises broad BMW E/F coverage and lifetime PC/card-reader updates for the BMM V3.0. It is a candidate for a standalone route. That general description is not an exact S85, SMG III, DSC, EDC or Touring-controller matrix.
Ask: “Can this exact version read S85, SMG III, DSC and EDC fault memory on my UK M5?” Add the E61 self-levelling or body system if relevant, and give the build date. Ask separately about the interface, any named data and saving a useful report.
Do not infer older diagnostic-line compatibility from a modern F-series cable description. Ask about the actual early or later E60/E61 arrangement rather than improvising connector changes. Our iCarsoft BMM V3.0 guide explains the purchasing checks.
BimmerLink: eligible family, exact SMG access still matters
BimmerLink supported vehicles lists the 5 Series/M5 family from 2003, and the UK BimmerLink listing and release history release history explicitly names E60/E61 support. That supports considering the app route; it does not establish every SMG III or EDC readout. The paid full app and supported adapter remain separate.
The UniCarScan UCSI-2100 UK package is a Bluetooth LE candidate for iOS/Android; compare Developer adapter selector linked by BimmerLink and confirm the exact build. The current iOS requirement is 15 or later. An F-series ENET-only interface should not be treated as an E60/E61 purchase merely because both use an OBD socket.

OBDeleven has an important year boundary here
OBDeleven vehicle support excludes BMWs manufactured before around 2008 and describes support for most later E-series vehicles. The earlier M5s in this guide are outside that coverage; later cars need exact chassis and controller confirmation.
For an eligible later build, supported diagnostics require NextGen 2/OBDeleven 3 and the BMW-capable app, with the FREE plan. Optional apps/Credits differ from diagnostic access; paid VAG coding features do not become BMW functions. See OBDeleven Advanced Diagnostics and OBDeleven licence terms.
Do not buy a device or subscription to overcome an unsupported production year. Compare confirmed coverage against your actual report requirement, especially SMG III. The later registration of an early-built car does not remove that limitation.
Legitimate BMW software and useful records
BMW AOS is the legitimate BMW workshop route. Current entitlement, legacy coverage, Windows and interface requirements must be confirmed; see BMW AOS technical requirements. Historic DIS, GT1 or INPA references describe diagnostic history rather than permission to install copied packages.
For a one-off SMG or Touring investigation, a properly scoped specialist report may be more useful than several unconfirmed purchases. Ask which controllers will be read and what supporting information will be retained.
Keep the original scan, warning, mileage, date and service history together. A clear or recently erased report cannot certify engine bearings, every gearbox component or the rear suspension. Use electronic evidence alongside appropriate mechanical inspection.
Common questions
Does the SMG cog warning mean the pump has failed?
No. Several kinds of complaint can produce the warning. Obtain the separate SMG III report and an appropriate investigation before buying parts.
Can a generic reader show S85 throttle codes?
Some supported P-codes can appear. BMW-specific bank and related-code context can add useful information, but no code alone establishes the failed part.
Is an E46 SMG II scanner feature sufficient?
No. SMG III is a different gearbox arrangement. Obtain confirmation for the E60/E61 M5 and the actual function you need.
Can I treat a Touring scan as a Saloon scan?
The engine/gearbox scope is shared here, but E61 self-levelling and body equipment require separate controller and fitment checks.
