• Peugeot diagnostics.
    We have the capability, using our dedicated Peugeot diagnostic equipment and our knowledge of the Peugeot range of vehicles, to reliably diagnose system faults. We use the laptop based PP2000 for most earlier vehicles and DIAGBOX for all of the current Peugeot range. These are the same tools as the main dealers use.

  • All make diagnostics.
    Our "all makes" diagnostic tools are the Snap-On Modis Ultra™ and our latest addition, the Autel MS908 Pro. Together, these high-end tools will reliably assist all-make diagnosis. There is almost complete market coverage for engine diagnosis and other systems such as auto transmission, ABS, airbag, key programming, DPF regeneration etc. This is pretty close to having manufacturer specific capabilities for all makes and the Modis Ultra even includes an oscciloscope to go beyond simply "reading the fault codes" and get the diagnosis right first time. The Autel system also uses a J2534 Pass-Thru programming device to enable software re-flashing and ECU coding on a variety of vehicles.

  • The diagnostics procedure.
    Discuss the symptoms with the customer. Carry out a road test with the customer (if possible). Carry out a diagnostic fault code test. Carry out further diagnostic testing (if necessary) to ascertain the cause of any recorded fault codes (component or wiring failure). Report findings to customer

  • Notes.
    Please note. Upon initial computer diagnosis, a recorded fault code does not always give a definitive diagnosis of the cause of the problem and further checks are required to discover the cause of the symptoms/recorded fault code.

    We have many enquiries from customers who expect the "computer" to provide a definite diagnosis and then we simply exchange the faulty part. This isn't always the case. We prefer to be clear from the outset and make customers aware that diagnostics procedure is not just about plugging up the computer.

    The vehicle's On Board Diagnostics (OBD) system will certainly aid initial diagnosis and provide useful operational 'freeze-frame' data at the time that the fault occurred. But, our experience and knowledge may be required to find the root of the problem. As an example, an engine misfire may produce a P0301 (cylinder 1 misfire) fault code only. But why is cylinder 1 misfiring? Is it an air leak, faulty spark plug, blocked fuel injector, lack of cylinder compression, sticking valve etc. Only further "back to roots diagnosis" will provide the answer. To make it easier, that misfire code could be accompanied by a cylinder 1 fuel injector circuit fault code. So, operation of the injector is causing the misfire, but is the injector or wiring to the injector at fault? Further diagnosis may prove that a wire controlling that injector and several feet away is the actual cause of the fault (not the injector). So, the computer correctly told us that cylinder 1 was misfiring but was not able to tell us why.

    Also, current diesel "HDI" engines incorporating a diesel particulate filter (DPF) can exhibit the "unblock diesel filter" message on the driver's multi function display. This is very misleading for the owner as the message actually relates to the exhaust particulate filter and not the diesel fuel filter. What's more, the error code could be due to a blocked particulate filter, faulty pressure sensor, split/blocked pressure sensor pipe or wiring defect. So, "blocked filter" doesn't always mean just that.

    Please understand that your vehicle's fault monitoring system will only monitor electrical sensor inputs, component outputs and the engine's performance to comply with current emissions regulations. It doesn't substitute the engineers diagnostic abilities.

  • In short, diagnosis of your car's fault, whatever the make, will not be a problem for Autosolutions!
