C6 S6 - a love(hate) story. (long...)

Not a nag, I share those same concerns. But having lived in China for many years, I think I can spot a cheap Chinese knock from a mile away. I’m hopeful, mostly because the packaging looks legit and the Chinese knockoffs are horrible with packaging. They just don’t care.

But I do have my fingers crossed and will report back when I can…

Good attitude. I sometimes hate saying things to people as most people want to always believe that they found gold when its not. You have a good outlook and as you mentioned probably have a good idea on what to keep an eye out for.

Just to let you know its not just me. This is what komseh said about the cheaper injectors. As like I mentioned some people got the same cheaper injectors and had some serious issues. When you get the car back you should be able to log the car and see if there are any issues.

Now that I think about it. If you had 3 bad injectors even 3 not top flowing injectors are going to be better. so it will be interesting to hear how it runs now that it has 10 fully woroking injectors.

Finally. Out of action for a few months because of summer, but I got the car back after cleaning injectors and replacing 4 new ones. Also had to replace 1 coil pack that was installed about 5 months ago.

I only did a short drive last night, but the car starts and drives smoothly with no detected misfires. It also sounds a bit louder now–but I think that’s because I’ve been driving tiny rental cars lately.

It’s still too early to say about the Hitachi injectors, but they seem to be working fine for now. At <$60 each, this could be the place to go: https://www.wpdusa.com/products/26574/225702-Fuel-Injector-Hitachi-840151080397-FIJ0033.aspx.

Someone buy one and get them flow-tested against a ASNU-cleaned OEM injector. I have a spare one to contribute to the cause…

its good to hear the car is back up and running.

The car is going to have a different sound as the one injector was bad as you said. That will rob the motor of a lot of power. Did you get any real reasults from the testing and can you post them

No fancy write up with results. Apparently that is a separate software package and these guys do mainly turbo diesels. I just got some photos. Here is a sample with the bad injectors after cleaning.

WOW thats a big difference and you said thats after cleaning. I would wonder what it looked like after cleaning.

Those are all over the place. None of them look really consistent. This is the number one reason why I keep telling people to get the injectors cleaned and tested. Getting new injectors is a nice idea but over all you still want to have them tested. Moxofia your situation is a little different you were running out of time and didnt know you had a few bad injectors.

That picture says a 1000 words and its important that people see this. That one cylinder looks to be 50% down on the other injectors. What that means is that cylinder is going to be running super lean and the end result usually is a bad cylinder after a while.

Yes. I ended up replacing 4 injectors - 2 were flowing too low and 1 had a burned pin. Now I’ve got no more misfires, and the car generally runs well.

But I’ve got this crankcase vacuum problem and also this code:

P0024 - Camshaft Position Actuator B Bank 2, Timing Over-Advanced

That solenoid has its wiring harness resoldered. There may be a bad connection or the solenoid itself is bad. Don’t know yet.

Try clearing the code if it comes right back then you might have an issue with the wire

With a new cam solenoid and the repair of a bad pin connection into ECU2, it seems like all my big problems are over. New plugs/packs/fuel filter, fuel injectors cleaned/replaced, fresh oil change and now everything is running smooth again.

I’m going to wait until I drive at least a full tank without a CEL before I call it done, but right now the dash is dark and it’s a think of beauty. I haven’t replaced the belly pan yet - and I think that makes the car sound even better.

WOW great update. These cars are very solid once you get the maintenance all worked out. In your case you had just some odd bugs that probably popped up when you had the motor out. Those can be hard to track down but you kept with it. Great job now you should be clear sailing for many many miles now that you have done all the work

If everything is still clear after 500 Km, I’m willing to call the misfire issue done. But I still have the following on deck:

  • install new AC compressor & related parts
  • new or JHM upgraded intake manifold (currently running without internal changeover flaps)
  • install driver-side valve gasket
  • check possible front diff oil leak

Other than that, I just need to do an annual service interval.

But the bigger problem is 2-fold: 1) my wife has lost faith in the car, and 2) we’re moving to Malaysia (RHD) in 7-8 months for a 3-year posting. So I have to decide if I am going to sell the car (here in BG or back the US) or send it back to CA for my brother to drive while I’m gone. I still have some time to see if the car can win back her doubters, but we’ll see…
