A life extension for your variable geometry diesel turbocharger.
"I bought this after getting remarkable results from the complete kit, which comprises the liquid and a hand-pressurised squirty bottle. What it does is free off the variable vane system inside modern turbos as found on VWs, Volvos, BMWs, Skodas and similar. You go through a little ritual with it, firing the liquid into the engine air intake on a timed cycle (the instructions are on the squirter). In my case, it made an immediate and impressive difference to my 170,000 mile Volvo V70 D5, which was stuck almost permanently in limp-home mode because the air control vanes inside the turbo were jammed in position. This liquid cleaner won't fix the underlying cause of the jammed vanes (in my case, a pretty impressive oil leak) but it will buy you time enough to save up for the real fix (buying a new turbo). The instructions say that in some cases, more than one application is required to get the full effect, so I tried a second dose which is my I bought the refill: My only criticism is that the squirty thing I got in the original kit is not very well made and started falling apart during my second dose process. Unlike the other solutions to sticky vanes, which require the turbo to be opened up or taken off the car for cleaning (aka "Mr Muscle Oven Cleaner" fix), it's possible to use this stuff equipped with no more than a screwdriver and a semi-willing assistant who can read the tacho and press the throttle while you pump and squirt (as it were)." - misterbonduk
