minismood Posted July 17, 2007 Report Share Posted July 17, 2007 Hello!Car: Lupo 3L TDI, year 2000, Description: Last night my lupo started to lose power when driving at about 80 km/h. It feels like the turbo is not setting in. Is the turbo charger "broken"?There´s no problem driving the car but I can´t get over 110 km/h and the acceleration is very slow.I haven´t changed the fuel filter for maybe 3 years or so. Can this be a factor?I changed the layers of the two front wheels one month ago. Can the ABS-sensor be a problem?I will be ever so grateful for any help!

Mike_M Posted July 17, 2007 Report Share Posted July 17, 2007 The filter should be changed every two years and the water drained from the filter every 6 months or so........but also sounds like a boost leak Quote Link to comment Share on other sites More sharing options...

Mike_M Posted July 17, 2007 Report Share Posted July 17, 2007 (edited) A popped off hose or even a cracked one...........check from the intercooler to the engine and the airbox to the intercooler.Worth checking small vacum pipes too.I had power loose on my chipped Golf GT TDI 150 and it ended up being the intercooler hose popping off due to the high pressure the engine was creating........ran fine, but until you decide to floor it there is no power. Once put back on power returned.Change your fuel filter on the the TDI too, as it plays a big part with the TDI performance.......draining the water it collects every six months is worth it too. There is a small plug at the bas of the filter that once undone drains the filter of the filtered water, so make sure you have a mug ready.

Mike_M Posted July 18, 2007 Report Share Posted July 18, 2007 No probs.I would change the TDI fuel filter every year, but that is me..........but do drain it every six months at least Quote Link to comment Share on other sites More sharing options...
minismood Posted July 18, 2007 Author Report Share Posted July 18, 2007 No probs.I would change the TDI fuel filter every year, but that is me..........but do drain it every six months at leastToday the power loss began again.. style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> very strange...I´ve driven it about 20-30 miles, about 4-5 times, without any power loss after the fuel filter change. But today it began losing power again. I´ve pulled the car to the curb and switched the engine off and started it again after a few minutes and after that the car ran fine until I got home 30 minutes, a couple of miles, later.On another home page someone mentioned a vacuum hose in bad shape. Should I look for something like that? Or could it be anything else, an electrical problem or something else?Thanks for your help! Quote Link to comment Share on other sites More sharing options...
Mike_M Posted July 18, 2007 Report Share Posted July 18, 2007 As stated before check all the hoses and the small vacum ones too Quote Link to comment Share on other sites More sharing options...
