I don't know about the turbo running at half, but I can give you two ideas.

If it only started after the timing belt was replaced there is a very good chance that the timing is off. The car has very specific instructions due to the variable valve timing.

There is also a chance that there is a hole in one of the turbo hoses. One way to check for a leaking turbo hose is to put the car in reverse and set the parking brake. have someone listen for a large air leak while you power stall the engine. if there is a leak it will make a lot of noise and you can feel for it with your hand, just don't burn yourself.

DO NOT POWERSTALL THE ENGINE MORE THAT THIRTY SECONDS AT A TIME AND NO MORE THAN TWICE. IT WILL GET VERY HOT VERY QUICKLY.

DO NOT SHUT OFF THE ENGINE RIGHT AFTER POWERSTALLING. THERE IS TO MUCH HEAT AND COULD CAUSE DAMAGE. LET THE ENGINE IDLE FOR THREE MINUTES AND IT WILL BE FINE.


I hope this helps

We imported a Volvo V70 Turbo diesel model 2000 in Abu Dhabi...It seems to be the only one in UAE and the Volvo dealer is not able to diagnose the engine problem we experience, no technician and no computer software to check it.\r\nThe engine run smooth at idlle but there is no power at all when we accelerate the engine.
The problem started first with the fact that the turbo was not kicking in. Then we drove the car without the turbo but the car was reaching its top speed but without the added power for accelaration. Now the problem is worsening as less and less power is delivered.

Yes, your intercooler is a problem cos it cools down the turbo charger. The turbo is what gives you your extra power, and when it overheats, it loses pressure and thatcauses loss of power.

Volvo V70 xc AWD '98 - fuel filter change


Brandonlo168,

The fuel filter can be located under the carpeted cargo storage floor at the rear of the wagon. Remove the four 10mm bolts, remove the cover. You will then see a removeable plate to the right just behind the rear passenger seat. Fuel filter can be seen through hole in hole. Replaced from underneath wagon. Be sure to make sure lines are fully inserted onto filter. Check for leaks. No smoking, extinguisher handy. Note arrow on filter for correct fuel flow.
