for about 4 months... now very hard start, need to crank for 30 secs when cold just to have the car feel like coughing to a start. no codes. ect reads normal, nothing unusual in vag meas blocks. car is sluggish while running. fuel pump seems good and fuel filter new. 6mo old spark plugs and wires. thoughts?

Where did you get the coolant temp sensor? Failure rate is high, and I have almost zero trust for aftermarket.
