It does not have power to overtake although when stood it will rev it is an audi A3 1.9 tdi and is 2000
Your motor probably runs in "failsafe" mode (won't go past 3000rpm in highest gear), but in that case the ECU warning light should also come on (which might also be broken ofcourse).
Try releasing and reconnecting the battery (-connectors), which should "reset" any fault-codes in the ECU and see if the TDI power is back. Please note that the "cause" of the ECU faultcodes will probably put the motor back in "failsafe" mode within minutes ! But at least you've verified that your motor runs in "failsafe" mode due to serious faultcodes in the ECU.
You should have a dealer/expert read the ECU faultcodes using VAGCOM to determine the cause. A dealer will charge something like 50~60$ for it.
Since it's a 1.9TDI my best guess is that's it a broken N75 turbo-valve (common TDI issue, replacing the part yourself will cost less than $30 and 15 minutes). When the dealer suggests a complete replacement of the Turbo-unit (quite expensive), please have a TDI-expert do an 2nd opinion ...
