Hi, my car volovo xc90 2007 , every time starting the car i get message (ENGINE SYSTEM SERVICE REQUIERED) what are the possible issues may cauze it?

Possibly reset issue.
Google "D3 service interval reset" for instructions.
It is probably through the menu system.

Service interval mileage is also selectable on A8's through the menu system. I very much doubt anyone has altered this.

you need a coile

I don't understand your question do you mean the car won't start or u loss power to the engine the only thing I can tell you if u go to autozone get free diag test tell me what the codes r then I can help you sorry but without codes I'm lost

The light will always come on when starting to indicate it is in working order. No problem unless the light stays on after starting.

Hello,

" service charging system ", means you have an issue with your battery, your alternator, or
your voltage regulator. Something is causing your battery not to charge properly. You should
have it checked as soon as possible. This could keep your vehicle from starting next time.

I hope this helps you.

your fuel pump lines your fuel pump could be the cauze

if you look in your owners manual in the glove box it will tell you how to reset it,it will be in the section oil life

take it back to them,a job done by the dealer has a warrenty period ,,Havent a clue what the fault could be ,anything from the oxygen sensor to a blocked air filter or just a fault in the computer,You could try disconnecting the battery and holding the cables together for a minute to discharge the capacitors that hold the memory in the ECU

The 2.2 ctdi engine has a timing chain

fill port is on the radiator support (passenger side) To fill a volvo s60 you fill in on the high pressure side and most stores sell kits that only fill on low pressure. You might have to take it to a shop to get the a/c refilled.
