100% correct.
Or sometimes your lucky and get a vehicle that never has problems. I wonder if the previous owner replaced the cp4 in my car before the diesel gate scandle. Or had it tuned, deleted with the cp3 pump and returned it to stock. No idea of knowing unless the prev owner remembers the vin and is on here.
VCDS will give you some info..... other tools will give you more.... the dealer tool can compare what it reads off whatever vehicle against their database, and as soon as it doesn't match, they know you've "messed with it".
Ahhhh I see, but my question now is if my mk6 and my buddies mk6 have kerma and they still did all his work under warranty I’m guessing I have a 50/50 chance of them being lazy with my tdi?There's also the CVN (ECU flash checksum more or less, which if it doesn't match what VAG has is a big red flag)
Yupp. It was tuned before. 3 are from me. 13 attempts and 8 successful. 2 would be from vw.VCDS will give you some info..... other tools will give you more.... the dealer tool can compare what it reads off whatever vehicle against their database, and as soon as it doesn't match, they know you've "messed with it".
My crystal ball is broken, so I can't tell you what the odds are.
Sometimes they just quickly read the codes and authorize the repair. I was asked a few times to bring my car in. Then was called by the supervising tech. Flat out said, "we'll cover a failed hpfp regardless of tune. Done it more than a few times. (Even my stage 4) We cannot prove the tune caused it to fail, because we have virgin vehicles they fail on. turbos are iffy though. But with 140k on yours I'm surprised it hasn't been replaced. We've had new hpfp fail in 30k" but many of them here are tuned. I've seen 3 others blowing black. But yeah 50/50 all they can say is no. But you can go through voa and they have to prove without a shadow of a doubt that the tune caused it to fail... They can't.
Some of the tech here use vcds to avoid that.
Only about 3k miles left on warranty. I checked ash/soot load yesterday and both were still low (.04l ash / 10.46g soot measured, 19.9 calc). I had to force a regen in July when the soot hit 52g measured, No leaks under the car or in the valley, no noises, etc. My cars never go anywhere unless a specific warranty issue or recall. Nothing gets done that would affect an existing tune once I have one (BEW glow plugs...).
Huh? Doesn't your CPNB use the newer "staked flaps" on the manifold instead of the old style individual runner valves? Are you removing the whole V157 unit and airguide pipe or just making some adapter, etc? Post a pic of your parts so I can understand what's happening.
It may be the generic name of their delete tune. I only specified that I was removing the DPF/Cat downpipe. Most of the hardware will stay in place, the tune just stops using it. EGR mostly (I assume flaps close to increase EGR flow?). The DPF/Cat is getting removed. Since I believe I have to revert to stock annually, everything else will stay in place. I'll check the readiness monitors to confirm, but my understanding is that the will show "not ready", but no CEL. N/A may pass - depends on if DMVs computers have gotten smarter or not.
It seems to be like my BEW EGR delete. There was a throttle and little flappers in the intake that closed to increase EGR flow and mixing. With the delete tune, they just no longer operated but stayed in place. Throttle open all the time (I removed the throttle plate anyway). Since the EGR never opens, no blank is needed.
). That probably took longer than the whole rest of the exhaust replacement. Next time will be cake.
It feels pretty good. Low RPM torque is noticeably improved. It pulls in drive like it did down a gear in sport prior. Not neck breaking by any means. The TCU tune should help some from what I understand. I did some pulls in manual mode yesterday and it kept upshifting on it's own early. It may not have been warmed up though. My drive home today should give a better chance to play with it.
