My blitz turbo timer calculates time fine and displays how long the car will continue running but when i turn the car off the time sets to 0 and turns the car off, it used to work fine but now i dont know whats wrong with it, i messed with a few settings and set the minimum tome to 30 seconds but the car will still turn off.

If it has an uprated turbo the turbo timer runs until it gets to a set temp or length of time

Start at the turbo and check for loose or blown air lines . Check the intercooler for cracks. The turbo whine is normal but you would not be hearing it as the turbo is controlled to vary the amount of boost needed for the throttle setting. If you have to use starting fluid to start a diesel then it is time to consider a re-ring and bearings for the engine.

Run the scanner/computer the BCM can be faulty. do not waste your time and money. the electronic in the new cars tech, is very complicated.

God bless you

Michael,

It sounds like a Turbo timer, but if your local dealership has taken a look and they couldn't see one, then maybe not? Turbo timer's let the engine run for a period after you remove the key to let the turbo cool down before being powered off cold..

Your Volvo does not have have a problem at all. The feature is what is known as a 'turbo timer' and is an important part of most turbocharged vehicles such as yours.

Your volvo is powered by a 5 cyclinder 2.4 liter engine that is turbocharged. Which means the engine works on the principle of 'forced induction' whcih helps it make more power.

A turbo like yours has a small impellor placed in the early section of the exhaust which is then spun up by heated and expanding exhaust vapors. this power is then transferred back to a 'charger or pump that actually forces additional air into the engine resulting in the ability to burn a more powerful mixture of air to fuel. Unlike your engine which even under very aggressive driving will only sustain forces at most approachign 9 thousand rpm, a turbo charger often spins with speeds in the tens or even hundreds of thousands of revolutions per minute. because of this they depend on a steady stream of engine oil to both lubricate and saturate the very rapidly spinning parts to keep them cool.

when the engine is suddenly shut off after a long or spirited drive the oil pump also stops, this could result in overheating and damage to the turbo.

As a result of this, Volvo was one of the fisrt companies to install a 'turbo timer' mechanism in its T models which as you noticed will continue to operate the fan for a pre calculated amount of time after you shut the car off in order to properly cool down the turbo.

Again your car has no problem whatsoever, this is a good thing and a nice feature to have whcih will definably lend itself to extending the overall life of your engine over time.

Hello you def have to start with a good battery!!

If this truck has a turbo it might just be the turbo timer.
or
This could be a sign that your timing is out, (the engine is "running on")

it could be a exhaust leak.or a hole the exhaust .u would think they would be a sensor on the turbo when it starts going yhat make the engine come on.

Yes it pays to have a Turbo timer or let it run for 3 minutes after an outing.
An Intercooler is usually fitted to turbo charged engines.It cools the air entering the engine making it denser,Thats why cars go really well on frosty mornings after they reach running temp.
Hope this helps.
