Here's a little story about a few events over the past week or so. Bare with me.
I have a 2005 ZD30 auto that I bought to eventually put my TD42Ti motor into. When I got it, it had an "oil leak" from somewhere under the engine cover but didn't know exactly where. Never really mattered to me as it seemed to go ok.
A week or so ago I got some gauges fitted including boost and pyro. The guys doing the work had to take the engine cover off to fir the sensors. They showed my the state of the engine under the cover and it was a mess. No wonder it used to "mark its spot" in the driveway. I sort of knew I was in for a new intercooler as well.
Anyway, they replaced a cracked piece of intake hose, fitted the gauges, and by after 5pm I was on my way home ........
Until I got about 5km down the road and she had almost no power in her. It got the better me so I pulled over to see if I could see what happened. It had blown an intake hose off. Fixed it. On my way again.
On good Friday we headed to Dorrigo with some friends in a convoy. Up Dorrigo mountain she started blowing heaps of smoke and had little power, pyro went close to 700degC and boost only went to 5psi.
I put it down to the leaky intercooler, so persevered with it over the weekend. Ordered a new intercooler off ebay and de-greased the engine bay. That's when I noticed the culprit. The bloody intake hose had come off again.
So did it up again - all good.
Nope. The thing was making a weird squealing noise, and making heaps of boost. I assumed it was because the ECU had "learned" from the previous boost leak.
I remember reading somewhere here, maybe GEEYOUTOO's thread, that if you disconnect the battery for 20 minutes, the ECU will reset. So on Sunday I disconnected the battery and waited.
When I reconnected the battery I was really anxious to see if the trick had worked. 2 seconds later a siren starts going off under the bonnet.
DAMN. Look around and notice there is a little speaker on the rhs inner wheel guard. Bloody after-market security system that I had no idea was in the car. So I go looking through the owner's manual to see if there was any info on it. BAM - here is the brochure. Damn - no security PIN. What to do now.
Out come the pliers and off comes the speaker. Problem fixed. Security system is coming out on Friday so I don't have to worry about the hazard lights going while driving down the highway.
Now the boost seems ok. Slight intake noise but the engine cover is not on yet so hopefully it's nothing to worry about.
All this drama and the ZD30 is coming out in a month or 2 anyway.
