Re: [Amel Yacht Owners] Volvos.......
Hi,toggle quoted messageShow quoted text
I had a similar problem on my Amel 54 with Volvo 110hp turbo. Thought it was the turbo but it turned out to be the sensor which measures turbo boost pressure. It is located on starboard side on the Volvo and 5 minute job to change but expensive part 350 euros. Problem solved. I had to get a Volvo technician to diagnose the fault with his computer though as I was unable to diagnose the problem.
Do you have an EVC computer thing giving boost pressure? If that is stuck the EVC will limit the rpm. Sometimes these modern engines can be too clever! You could also check the turbo is sucking and the little arm goes back and forward. If it is stuck just work it with some WD40. If the boost pressure does not come up then I think it is the sensor.
Can you get 2800 in neutral? When I had my problem i could get 2800 in neutral but not under load.
