Question about Volvo S40

My car started loosing power, i had it in the garage and they cleaned out a filter that appeared to be blocking the turbo from cutting in, it has since gone into safe mode and wont rev above 2800 rpm. I had the air particulate filter serviced about 18 months ago.

Whistling when accelerating outlander turbo diesel

turbo whistle is common as it comes from the tips of the compressor wheel passing through the sound barrier and the turbulence occurs. IN the older trucks you would the turbo whistle as the engine reached full RPM just before a gear change. In smaller engine it is not do noticeable as there is an excess of air pressure that keeps the compressor wheel at a lower rpm and the pressure is dumped out. Turbo compressors reach revolutions in excess of 120.000 rpm under full load If it has just started to make the noise then check the intercooler system for leaks--loose clamps--- splits - Have the turbo compressor checked for damaged fins from the ingress of fine dirt from a bad air filter---check the air filter is not blocked as the turbo speed may result from running in a partial vacuum ( no load on the compressor wheel)

Loss of power

I would start by checking for a fouled spark plug/wire. Also, check the fuel filter. It doesn't have to be good just because it is new. Could have a factory defect.

My peugeot 206 diesel keeps cutting out, now it

In my opinion cut off problem occurs if engine is not getting sufficient fuel and/or air. Clean the air filter, turbo filter and fuel filter. Check the continuity of diesel flow from filter to hdi pump. If you haven't found any problem there then the possibily the hdi pump and injectors section needs to be checked. If the car has done more than 100000 miles then clean inlet and outlet manifolds including check of turbo and EGR valve. Do everything whatever possible before you take your car to garage. If there is no luck then let your car diagnosed and check any error code recorded by ecu.

19 tdi loss of power

I have a 1999 VW golf tdi with intermittent loss of power. The turbo will cut in for a few seconds, then die forcing you to change gear and get a small boost again. The turbo will not boost much past 2200 rpm. The cars computer has been plugged in at the garage and does not show any problems. Various people have said, replace turbo, air mass meter or just simply wash turbo filters in WD40. Can anyone help?
