My Dad has had to replace the temperature sensor on his Picasso after getting incorrect readings on the temperature gauge. The old sensor came out fine along with the clip that holds it in. the problem is that when fitting the new sensor the piece of plastic that the clip sits in to hold the sensor in place has broken meaning it won't hold in place.
Is there any way to easily fix this or is it a case of removing the housing that holds the sensor in place and replacing it? It's looking like it could be a garage job if the housing has to be removed and replaced as the small nuts and bolts that hold it in place are extremely difficult to get to without risk of losing them.
Thanks
Dave
