Hi, Recently my A5 3.0tdi seems to not come on to boost until around 2000rpm.
Before this I noticed it was down a lot on low end power and initially thought it was to do with the accelerator pedal as you seem to have to give if more for it to actually accelerate as before it was quite effortless with just a small amount of throttle.
I did a throttle calibration and thought it helped at first but seems it hasn't.
Also scanned the ecu with my ross tech cable and I'm not getting any error codes.
What would be the best approach to finding the fault.
When boost does kick in at 2k it kicks in hard .
Also to add it's a manual.
Thanks.
