Three diagnostic options to suit your needs
Electronic faults are not always visible. Left untreated, they impair performance and can lead to more serious breakdowns.
Engine warning light and fault codes
Reading and analysing fault codes, guided fault finding: engine, ignition, instruments, air conditioning, ABS, parking sensors, suspension, automatic gearbox adaptations.
Noise, loss of power, difficult starting
Knocking, unstable engine speed, increased oil or fuel consumption, 'Drivetrain' message: an in-depth check to anticipate a serious failure.
Buying or selling a used BMW
In-depth checks for mechanical, electronic or structural abnormalities affecting the vehicle's value or reliability, in three packages.
What engine diagnostics check
The workshop knows the weak points of BMW engines: each measurement confirms or rules out a possible cause.
Fault codes and parameters
Reading, analysing and decoding faults, then comparing actual engine parameters with reference values.
Compression and pressures
Cylinder compression, oil pressure (pump and crankshaft bearings), fuel pressure (pump and regulator).
Borescope
Inspecting hidden engine components without dismantling, to assess their condition and the nature of any damage.
Injectors, ignition and fuel system
Engine smoothness when cold and hot, oscilloscope signals, exhaust gas analysis.
Timing system and turbo
Checking the condition of the timing chain, turbocharger, battery and alternator.

BMW diagnostic check: BMW engine warning light: read fault codes before replacing a part
An engine warning light does not tell you which part to replace: it indicates that a control unit has recorded a fault. Reading the fault codes identifies the circuit involved; guided fault finding, measurements and a road test confirm the cause. This avoids replacing a sensor, coil or EGR valve at random.
In Ostwald, Askwert Motors brings together experience of BMW engines and the equipment and approved software needed for these diagnostics, on BMW and MINI alike.

Which pre-purchase inspection should I choose?
Essential (€180 incl. VAT) covers faults, mileage and a road test; Advanced (€360 incl. VAT) adds history and bodywork; Premium (from €540 incl. VAT) adds borescope inspection, compression tests and a detailed report.
