Hi,
Slowly but surely, my suffering is coming to an end. It's about my Phaeton; the hard drive failed.
I replaced the high-pressure pump (used one), flushed and cleaned everything thoroughly. I had the injectors refurbished, and programmed all the new IMA codes using VCDS.
During assembly, a connector on the leak line broke off, so I bought a new leak line (unused) on eBay.
After that, I went on the first test drive and discovered that I was experiencing intermittent power loss, mostly during strong acceleration or under heavy load.
From that point on, the problems started. At first, I thought it might be the used hard drive, so I bought a new one. Unfortunately, that didn't fix the issue, and to make matters worse, the computer had a very unpleasant warm-start behavior (it took a long time to boot up).
I thought it might be the injectors, so I ordered and installed a second set, but unfortunately, they behaved the same way as the original ones.
It took a long time, and after several tests, I finally found the "new" leak.
The power loss issue is gone, but the cold start behavior is still a problem.
Attached are the values I read out.
Thank you very much.
I assume that cylinders 1, 2, and 5 are faulty.
