Most shops should be able to quickly check them with a DRB handheld scanner. This is the best way to do it.

You have a few possibilities here one cleaning may fix it which is about 500,00 to have done the proper way or you can order a complete set of rebuilt injectors.

How many miles are on it and what year is the engine? 24 or 12V?

its a 2007 12v
How many miles are on the engine?
Customer: replied 5 years ago.
156 000
If the engine is from 2007 it should be a 24v

But I would recommend replacing all with rebuild injectors.

You can send the old ones in to be rebuild to have a backup set for the next few hundred thoudand miles as well.
