Rokasgr Posted November 3, 2018 Report Share Posted November 3, 2018 Hello, I have a VW lupo 3L and i have a problem with start up. It starts only with the cold engine. Abs ant parking brake lights are blinking. And another issue when I drive it, it doesnt run faster than 80km/h it just locks and only on cold engine the power is fine and i can go faster, but when it warm up it lose power.

mk2 Posted November 3, 2018 Report Share Posted November 3, 2018 Welcome to club lupo! Check the temperature sensor. But it is possible the fuel filter may have water in it? ABS and brake lights may be low brake fluid and faulty wheel sensor? Quote Link to comment Share on other sites More sharing options...
Skezza Posted November 4, 2018 Report Share Posted November 4, 2018 I would start with the fuel filter as mk2 said, but also check the accumulator. It might not be getting into the higher gears. Quote Link to comment Share on other sites More sharing options...
RAB Posted November 5, 2018 Report Share Posted November 5, 2018 Get it scanned with VCDS. When was the fuel filter last changed? If you don't know, change it. A problem with the accumulator would disable the accelerator. RAB Quote Link to comment Share on other sites More sharing options...
Rokasgr Posted November 6, 2018 Author Report Share Posted November 6, 2018 And i forgot to mention that, this car has a bad fuel economy. It uses 6.5-7l/100km diesel. Does the fuel filter have a huge impact? Quote Link to comment Share on other sites More sharing options...
RAB Posted November 7, 2018 Report Share Posted November 7, 2018 When was the air filter last changed? Can you manually move the VNT mechanism? RAB Quote Link to comment Share on other sites More sharing options...
Rokasgr Posted November 7, 2018 Author Report Share Posted November 7, 2018 I have changed air filter one week ago. I havent checked VNT. I have bought new glow plugs, oil and oil filter. And now i need to change it Quote Link to comment Share on other sites More sharing options...
