Hopefully i can help..


The "engine system service required" is basically your warning message that the ecu flags up if in the event a fault is picked by the cars main ECU "Engine Control Module/Unit" in regards to the engine control management side of things bit like the engine managment light - Its not a service light alot of people think that but its not - however this message can cover a huge area of possible faults in regards to the engine itself from wiring/plug connection fault/air intake leaks or vacuum leaks/fuelling issues even to mass air flow sensor problems.So in reality to fully confirm exactly what the ecu is seeing the car needs to be diagnostically tested - in which a diagnostic machine suitable or covers this type of vehicle will need to plugged in to determine or retrieve and clear the faults codes from the ecu - only then once you/garage - which does not have to be the dealer - can you really progress further with this and check and investigate further into the problem...Its most definitely the cheapest way forward to do the testing first rather then just replace parts.but a full visual inspection of any split air intake tubes/vacuum lines any loose wiring plugs around the engine can be checked for first if required - So as above that's about the only way forward with this one unfortunately..
