This may be a long shot. So, I have a
Renault Megane 2, with a
2.0l Diesel engine with theoretical
340Nm of torque.
The thing that worries me is that when I push the pedal, it just takes some time to respond. It's like lack of torque and only get reasonable power at 2200 rpm, while in the specs sheet of the engine, I should get and appreciable power starting at 1500 rpm.
What can be causing the lag (and loss of power maybe)?
(Additional information: At idle, the engine vibrates, quite a bit, but don't know if it has something to with the problem above.)
EDIT 1 :
@Pᴀᴜʟsᴛᴇʀ2 The car is from 2007 with the 2.0L Diesel M9R. It has 150 000 km (~93 000 miles).
EDIT 2 :
Went to a specialized workshop and they found an error on the on-board computer. It indicated that it was a malfunction of some magnetic valve of the turbo. They cleaned the valve and nothing changed. They even tried a new valve without any success. Their conclusion was that the problem is from the turbo not functioning properly, which means either get this turbo fixed or get a new one.
Is it possible that the problem isn't the turbo?
