Thanks for that threedogs I will up the boost and check relays , I just changed changed maf sensor bout half hr ago.
I purchased a 2006 zd30 motor with a cracked number 3 piston that I'm building at the moment. Sourcing Pistons is a night mare trying to fing forged ones? Any info would be greatly appreciated.
I thought about mentioning this too, but I thought the engine light comes on only on the CRD, not Di, if you block the EGR. Somebody correct me if I'm wrong though.Originally Posted by Stropp

Hi, I'm also new to the forum and the ZD30. I've had this once already, don't forget the check engine light on these is also a 'water in fuel' sensor, drain the water out of the fuel filter housing, it needs doing now and again on the ZD30.

If you have a Super Cheap auto near by, they have the machine to tell you what the code is. I think it cost around $15 for them to plug it in. They can also clear the fault codes too. Blocking the EGR prior to fitting the Dawes and needle valve can cause over boost issue and this may have been the cause of the CEL coming on. Also AFAIK, the ECU has a internal battery, like a resistor or what ever they are called to hold power in the unit if the battery goes dead. I do believe you need to disconnect the battery for overnight at least for this to work. I could be wrong but I think I read it here somewhere about it.
Yes its the CRD's where blocking the EGR the CEL will sometimes come on and show a fault of the EGR. In the DI's case its usually an overboost issue, hence the CEL coming on.

Just like to say thanks to everyone, it's been a day and a half so far with no engine light coming on.
What I did , every thing everyone suggested, the problem was over boosting. Thanks again.
Glad the forum could help mate
