Short answer is that it could be except I don't know what ZD30 Neo is. I know as a fact that ZD30 versions engine heads aren't exactly the same, e.g. inlet ports have different shape or size... Sorry can't assist you more. Cheers

You need to check if it is vacuum leak or control solenoid going silly. This is a process of ellimination. You can connect vacuum line directly to actuator to see what will happen. Line with what looks like a little filter is the direct line from vacuum pump. Cheers

Please check the turbo actuator first, it should lift up fully and not fluctuate while the engine is idling. 02 Patrols have vacuum canister mounted next to intercooler and they like to leak so badly that there isn't enough vacuum generated to actuate turbo vanes. You can temporarily bypass it if needed when you see no movement in the actuator. Cheers

G`day, welcome to the forum. Technically, start up shudder is not or it shouldn't be caused by MAF sensor. You could try disconnecting it and than try to start. If you have access to multimeter you could measure MAF outputs at idle voltage should be around 1.7 to 2.0 V. Even better would be access to ECU Talk cable/interface and software, with that you can log engine sensors values to see what is happening. What you also could quickly check if the turbo charger VNT arm goes up/raises when engine starts and goes down when engine is off. Thast would elliminate vacuum control as source of trouble. Like vacuum leak or VNT control solenoid issue. To me, this could also be like classic fuel starvation. Check or replace fuel filter as needed. I'm guessing that if you have EGT gauge you have boost gasuge as well. So boost pressure would also be indicating lower values. There is also a possibility that EGR valve is stuck open perhaps partially this ofcourse only if you haven't blocked already. Cheers

Possibly not but one never knows, it could cause leaks at swivel joints, or if you had open diff breather. Noise could be caused by incorrect type of oil used as well. Cheers

Indeed ZD30 does have EGR valve issues from time to time but most of us fix that with teh shim. ECU uses/applies EGR and VNT control together under certain circumstances. Cheers

You need to check what the ECU is seeing as if your external gauge is showing 10 psi and you are getting limp that means that either the boost is past 18 psi or your MAF voltage is past 3.99 V bellow 3000 RPM. Boost and MAF signals are directly related. ECU Talk software with cable will make this easy, other way is with multimeter. Cheers

Bloody hell, you've been busy... Cheers

Have you tried just locking them to see if the noise changes. Normally noise when backing off is a sign of diff trouble but this being a front one which is normally not driven one wouldn't have thought that it is a problem. Unless this noise happens 4WD mode. Cheers

Do you have auto locking hubs or manual? Cheers

G'day mate, Welcome to the forum. Feel free to liven the space up a bit. Cheers

Here you go bud. One of these should apply.

Hi there, Welcome to the forum. It is a bit quiet at the times but feel free to contribute your wisdom and experiences. 3L GU on 35"s, how do you find the performance and fuel economy? Cheers

Hi there, welcome to the forum. Check the instructions how to diagnose and check subtank issues bellow. The pages are out of order but easily sorted out. Cheers

G'day mate, I'm glad you have sorted it out, in situations like these ECU Talk display or cable and ECUTalk software on the laptop are invaluable for identifying faults like these. I'd be lost without one. Cheers

OK per spring it costed ~ $2, you can have it for free as it is just a hassle to transfer such small amount. I'll PM you my address so all you need to do is send me a self addressed paid return postage envelope, the size of the spring is tiny.... Cheers Edit: PM sent,

I suppose I could part with one but how do you propose we do such exchange, it will be only a couple of bucks.... Cheers

Well I have a couple of spares (Dawes valve HD springs) but that's not much of a use (knowing it physical dimensions). Anyway description on the packet says 0.36x0.032x0.875 (I'm assuming in inches) Prec. comp. Spring there is also name Gardner Spring with part number 1-800-331-3263 and 36061Ci. Don't forget you also need Jaycar hand controller with the JDVM. Cheers

That seems familiar and is well known problem, normally reason for limps is also MAF voltage, usually anything over 3.99V under 3,000RPM will cause the fuel cut (limp) and usually in 3rd or 4th gear. Many of us with Dawes and needle valve boost control are battling this phenomenon either restricting the air flow capability (slower spool up) or using artificial means to alter to MAF signal either clipping it to stay under 3.95 or manipulating it entirely with voltage modifier. Some are slowing the spool up and max rate by reducing the maximum opening of turbo vanes (there is a stop screw in there) or quite a few are now using JDVM (Jaycar Digital Voltage Modifier) unit which works like a charm but is complex to assemble from scratch and also not that easy to configure (trial and error time consuming to find out the best setting). The results are however worth the effort. Cheers

Awesome offroad rig... Cheers

Hi there, Congrats on passing the magic 140,000 km mark after that they suppose to blow up anytime... if you listen to TD42 owners that is. Standards ZD30 is very laggy anyway and running boost at 10-15 psi is alright. Fitting needle valve and Dawes will take care of the lag. Cheers

Hi there, Welcome to the forum. Enjoy your stay and feel free to share your experiences. Cheers

Welcome back, You could have just contacted the admin, lol but hey you got there in the end. Cheers
