Turbo Surge Under Boost

[threedogs]

In a perfect set up yes then the exhaust drives the turbo not the ecu so much,
In your case you may need to drill a 10mm hole in the EGR plate so the ECU
doesn't throw up the engine light all the time, unless you have a scan gauge or similar

[Getaboutabit]

Yes I've got a scan Gauge so will be able to clear
engine light if or when it comes on

[threedogs]

would it be worthwhile taking the IC off and pressure testing it.?

[Getaboutabit]

That should be easy enough to do
I wonder what sort of pressure it would take
Probably not much needed to test

[threedogs]

I would only use a bike pump, or a quick squirt with the air gun ,tape up one end
and dip it in some water,
Dry with a hair dryer before installing again.

When was the last time you changed the fuel filter

[Mjcpatrol]

Had my surge under load and check light come on

[Mjcpatrol]

I check codes and it said dirty fuel or blocked fuel filter Chaged fuel filter and problem solved

[Getaboutabit]

It's going in for a service (40,000ks) this week so I'm waiting till that's done
before I do much else.

Just an update Nissan seem to think its a turbo problem
I'm getting a new turbo fitted next week all going well.
It's still under warranty so price is right will see what happens
