The saga continued in ways I wouldn't beleive.
Clearly I was learning some as I went.
The iCarsoft was decidedly unreliable. MAP pressure wasn't reading on one page, it was on another. It would also try to read other pressure in centigrade.
It had been on 2 Star machines and nothing conclusive.
I had done a fair bit of trial and error w/o success. I had gained a wiring diagram that was close to mine but not a perfect match so started testing and effectively redrawing as I went. That was slow, but at least it was nice weather, back then.
I bought a 4x DVD set off eBay, it takes about 70gig of PC space, 1 DVD wouldn't load and none works until all has loaded, the seller sent another. Loading these takes many hours but then I had the correct drawing, so back to testing.
Cabling all good, components test as good. When testing from ECU plug through components there were MAF, EGR and turbo actuator issues. It's possible that while testing I could have pushed the probes and opened the conectors, but I'm pretty sure the MAF and EGR poor connections aren't down to me. So connections restored and still the same.
I found the crankcase vent heater that plugs into the air duct out, had been for many ,000's of miles, still no difference.
I attempted to buy a Star for better interogation. The seller turned out to be totally unreliable, a long spin off story but it took 7 weeks to recover my money.
I bought a Star from another seller, more expensive it arrived in 2 days. It reset and the car was off, it even wheel span out of the road unexpedly, then back to fault. I reset MAF adaptations (a suggestion from and Indie on t'other side) and that seemed to be the answer.
Next day I took it on a 230 mile run. Here and there I could smell exhaust fumes and consumption was poor, occasionally it would go into limp and reset on the key.
The DPF temp sensor had thrown its hand in.
Remember I had stripped and rebuilt all sorts, over the months I had tried all sorts, including contacting 2 other Indies fairly local as I just wanted to say take the frickin' thing and let me know how you do. Being ex long they refused as their ramps and workshops couldn't cater.
I replaced the temp sensor, now it started smoking heavily, the exhaust fumes were strong. Nothing on Star aside from a communications code 8.600.0, I never got to find out what that could be.
I replaced the DPF, no surprise, no different.
Out with the 6 injectors and off for testing. All working ok but for no 6, that failed electrically. All were reading 183K ohms, but I now understand that there is more than a continuity test to look at electrically on these.
I bought a refurb injector, not realising that these are Piezo and many say a refurb of these isn't possible. The injector arrived and clearly it has new component parts.
Cut the seats for peace of mind, checked with a boroscope to be sure they were good,
new stretch bolts and copper washers. Smear injector grease on the shafts. Torqued to 7Nm +90, left overnight, it was late anyway. Next day add another 60 /70 degrees.
Bloody thing still smoking from about 40 degrees while warming up. Starts sweet, runs smooth, loads of power, just choking any other poor sucker on the road.
Maybe it's in regen mode? Still shouldn't smoke like this though.
2 weeks later the seller of the Star I was using messaged to say that software has been incorrectly installed and 'could' damage the ECU, too dangerous to use that then. He offered to take, right it and return it. I returned to him. As this was an eBay return case, at his request, they withheld £599 from him. He requested the money from eBay prior to returning the Star to me, they refunded me instead again w/o my asking.
I could just see more delays here, and in truth while I've learned lots I realise this could still be a steep curve, and I NEED transport.
And I don't mind doing some on mo mo's but crawling about under them hoping it isn't going to rain (or snow as is common up here) is something I want to leave in my past.
Is the replacement injector good?
Said Indie has suggested the possibility of an online software upgrade for the new DPF, well that's even beyond the Star machine if I had it.
Concerned that over fuelling could cause hydro lock, said Indie has assured that this is near impossible. On Saturday I drive 150+ miles and leave it for his attention, Larisa will follow me for the return home.
I am concerned that the hi exhaust temps may be detrimental.
Beleive it or not this is the short version,
I would be surprised if it helps others much but I hope.
Find a GOOD Indie and stick with him. After I fannied about with so much I'm lucky there is one, that so far gives confidence, that will touch it. I wouldn't want to.
after replacing CPS, DPS, EGR valve, manifolds, turbo, instrument cluster, etc.!
