CallumBB Posted April 7, 2018 Share Posted April 7, 2018 Hi Guys, I recently bought my 2003 1.6 FSI A3 and am having a problem with the fuel. When I start from cold and drive off it pulls lovely and seems faultless. Then 15 minutes into the drive once the engine has reached normal temperature I suddenly have no power at all. I'm dropping down gears, 5th has no pull whatsoever and 2nd, 3rd, 4th are all terrible. The engine still revs as normal however the car just doesn't go anywhere. I read the code P0191 from it which is linked to fuel pressure so my guess is that the high pressure pump isnt getting the fuel from the low pressure pump? Has anyone else had this before or know any tips?? Much appreciated, Callum. Quote Link to comment Share on other sites More sharing options...
Magnet Posted April 7, 2018 Share Posted April 7, 2018 Hello Callum, OK cold, problem when hot tends to suggest the car is running with a rich mixture. There could be a number of reasons, inc. the coolant temperature sensor, and although I am not a fan on being solely dependent on getting the car plugged into the diagnostics, it may well be worth doing so to hopefully determine the cause. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
