2010 Holden Captiva Pricing and Specs

There’s a variety of ways a turbocharged engine can lose boost. You might have a problem with the intercooler or even something simple like a dirty air filter. Don’t rule out a fuel supply problem which is causing the computer to reduce boost to account for a lack of fuel.

But one thing that has been noted in these cars is a cracked or broken boost pipe. If that happens, the boost will be lost to the atmosphere before it can get to the engine. Black smoke from the exhaust is a common accompaniment to this problem.

This is not an unknown problem with the diesel Captiva. The root of the problem is probably within the fuel system which is over-fuelling the engine. You need to check the fuel-pump pressure as well as make sure all the relevant filters and clean and there are no leaks anywhere in the system. Even then, the actual cause is most often worn out fuel injectors which need to be either reconditioned or replaced. Conventional wisdom suggests that reconditioned injectors will last about half as long as brand new ones before needing attention again. That said, reconditioned injectors are cheaper to buy.

Worn out or dirty injectors have been by far the most common cause of diesel over-fuelling, and the problem is not confined to the Holden Captiva.

The most common way to do this is to lower the window completely via the button, and hold the button down for an extra five seconds. Then, close the window fully with the up button, and hold that for another five seconds. Usually, this will reset the windows so that the body computer knowns where they are and can operate the automatic up and down functions correctly.

In some cars, you can achieve the same by standing next to the car and holding the locking button down on the key fob for 30 seconds. If that doesn’t work, try the unlock button for the same 30 seconds.
