hi
i have a 110 bhp 1.9tdi. being my first diesel i wasn't really sure on how quick iot would be so didn't really think nothing of it when i'm getting top speed of 85-90mph and takes an eternity to get there unless going down a hill. really poor acceleration is standard and if i'm cruising on the motorway and hit a big hill i cannot sustain my speed..
anyway i thought an ecu remap was in order, i had this done and had no real significant gains apart from possibly a tiny bit quicker off the mark. the guy that mapped it was really good and spent 2 hours of his own time with me. he was confused why the map made no difference but on driving it he said that i'm driving the car without a turbo.
i was told that a new maf filter was put on the car by the previous owner less than 2 weeks prior (i had receipt) so his attention went to the turbo. he took off the actuator and tried to wind it up, he was not an audi specialist but didn't think the actuator should be floppy and there should be pressure on the bar. on refitting again no improvement but he was sure there is nothing wrong with the turbo but it doesn't seem to be kicking in fully. i left there with the advise that i need a new actuator.
on returning home i decided to unplug the maf to see what difference it made and it hardly made any!
i'm no expert but if i unplug the maf shouldnt there be a noticable difference in performance? if this is the case then perhaps i didn't have a new maf after all and this is the power problem? can anyone fill me in or advise as i need to unleash the beast!
cheers
