Thanks to all of make? the various tests

[Matty23p]

Guys, sorry if I open the post some of you may know up to how many bars of turbocharger reads the map, before the failure??

[Exside81]

As you have brought the bit? Now you failure?

[gcmotor]

Unfortunately, this type of engine is of these jokes, the variable geometry of the tubes, consumed, mud manifold, valves, etc.. maybe before a good clean and then you see the rest

[francescosparco]

hello x for case, the problem is the from of 4 and 5 gear between 2500 - 3000 rpm to meta throttle?

To me also gave

I have gone mad long ago with the 147 jtd original...changed all the sensors with various tests and in the end it was the pierburg that works with the suction pump, and controls the variable geometry. Practically there was a delay in the management, and then the position of the geometry led to pressure peaks, which they sent me protection turbocharger

[jovandj]

Very common problem with the pierburg off or the tubing is cracked, or intake manifold very, very dirty idem air sensor (map) dirty or perfectly calibrated....little tip can sometimes be the actuator vgt the fungus to be clear that it breaks, preventing the proper management of the turbo

Change here change, until it becomes the centre!!!!! But a road test with a diagnosis..... and too difficult.

[huntersub84]

I agree. I at the time to first understand what it was, I had made a log with EDF on the road, I saw these peaks and after that I realized that it was a problem reading the sensors, but a problem of delay of the actuator
