Jarno Trulli believes that fixing the power steering problems that have plagued his start to the season is key to taking a step forward in form.
Although the team's T128 is a good improvement over last year's chassis, Trulli has struggled with power steering issues that hamper his ability to feel what the car is doing. With a major car update planned for the Spanish Grand Prix, Trulli is hoping that he will be able to benefit from the developments by having the steering sorted as quickly as possible.
"I am still struggling quite a lot with the power steering," Trulli told AUTOSPORT. "We have the issue with it, which is affecting me a lot and I am not able to feel it – which doesn't help when there are also problems with the tires.
"I hope I can get this sorted soon. The team is working on this more than the aero updates, as it really is for me the main issue. I can't feel the car; I can't drive it. But once the power steering is fixed then I think I can give the team everything they want in terms of feedback."
When asked if he was confident that solutions were in the pipeline, Trulli said: "Some have already come but none of them are working yet.
"We can still see from the data that there are still some troubles there. I hope we have got a fix for Turkey, because it is frustrating driving something when you don't know what is going to happen. I hope we can get it sorted."
Looking ahead to the updates that are coming for Barcelona – which will include a Red Bull-style blown diffuser, Trulli said: "This will give a bit boost to the team in terms of numbers. So for me, I really need working power steering. Once we get this, we can start really thinking about scoring points. Points are realistic, but whether it is possible or not we will find out. But it is looking good – it is looking positive."
