The TPS is probably for auto tranny, I do not know more about Renault Laguna.
There are other mechanical pump with TPS and N108 to control the timing electronically, and these pump do not have any sort of cold start device, because the cold start timing is setting with a small ECU, but not in your pump, no N108, and mechanical cold start is installed.
If you have a very good deal on it, buy it because It's a 20mm main shaft, lots of small engine renault pump are 20mm main shaft, I do not know why.
