The device makes itself a reasonable impression of the price, light and compressor functioned well. But to help launch a diesel 1.5l (description promises to 2,2l) it has failed to full line. More like a tortured gurgling of the starter was not to pick up. My vehicle has even decided to disable the ESP, so weak was the performance by the ignition (and obviously the pre-heating of the glow plugs).
Did it 5 times for guidance attempts (long Laden, 1-2min wait after ignition and max. 5 s start), but to no avail. Does the part unfortunately therefore return.
I give him 2 stars, because it is relatively likely that it should work quite passable for gasoline. Before the use of diesel engines, however, I have to advise against.
