The selected X5 E70 tank is restricted to the listed 2007–2008 3.0d and 3.0sd six-cylinder diesel applications. Its cap and level-sensor inclusions do not establish the correct reservoir for every E70 or X5 engine.
Keep the early diesel scope with the original reference and physical connections. A shared X5 name or broadly similar black tank is not a complete application check.
Read the listed references within the stated scope
The early E70 diesel tank with cap and sensor lists 17137552546, 17137647290 and 17138621092. Use those references within this selected application, not as a reason to widen the offer to unlisted petrol or later builds.
Send the VIN, actual build month and engine/application details when requesting confirmation. A broad catalogue family entry should not override the narrower supply scope.
Compare the complete tank and original sensor connection
Match the reservoir shape, filler neck, hose connections, mounting tabs and original level-sensor connection. Establish the photograph orientation before interpreting where an outlet sits.
A cap and sensor supplied with the tank still need to be the correct configuration. Do not infer an unlisted cap-pressure value, sensor pinout or diagnostic reading from a picture.
Keep service items separate from the package
The offer contains one reservoir with cap and level sensor. Hoses, coolant and mounting hardware are excluded. Have the installer determine any further items required after diagnosing the complaint.
A warning or loss-of-coolant concern does not by itself prove that the tank or its sensor has failed. Selection and fault finding remain separate checks.
Make a difference easy to review
Provide labelled original-part photographs of the whole tank, hose outlets, mounts and sensor connection, alongside the VIN and reference. Identify anything that does not agree. Use the vehicle-specific service procedure for testing, filling and installation.
