For sure! I've never gone over the 10k mi, usually I change it closer to 8k honestly. I write my sticker for 7-10k to give a buffer. And always with that LM Top Tech 4200 5w-30, I get it through FCP and do the LRG with it cause I'd be crazy not to.

Wow that's wild then. How many miles were on it when you bought it? Can you verify which oil the first owner used?

I can't remember exactly how many miles between 50 and 60k when I bought for sure though. And no I can't, car was from Michigan and I bought it from a local dealer that mostly sold TDI cars as the owner was an enthusiast. He got it from an auction. I think I am the second or third owner, I believe it was a buy back car.

I'm. I wonder if the first owner or two had run crap oil and long intervals. Nothing in Carfax to corroborate oil change interval?

To be honest I don't know nor remember what it said. I was thinking that too though possibly. Do you think I should even really worry about it? Only real reason I'm asking is because before I go about fixing a NOX cat efficiency issue I want to have an idea if it will be worth it.

Car is definitely not in warranty? That would be a great place to start. @SaVAGeSoot can probably answer better if it's worth it or not at this immediate point.

Nope for sure out of warranty, that was up end of last year I think, but it is for sure out.

What are you dragging me into now @volkswagens-for-life ?
You're a prime suspect for advising him, since you dumped yours because of emission failure fear.....
I also don't now what NOx issue he's having, as there's no link to where this "problem" is being discussed\diagnosed. 🤷‍♂️

Yeah, you're not wrong at all

He's concerned about how loud his chain has become. Maybe he should start a new thread to not clog this one up so we can chat @7P_Nate

SaVAGeSoot · Sep 9, 2024

Well, he's working with a CATA, so that means 4 chains vs 2 chains on the CNRBs like mine, so there's a few more chains and tensioners and slides in the system.... so this value we are tracking here isn't really a black and white metric or diagnostic method.

I can do that if you'd like! The issue is NOX cat efficiency below threshold bank 1 cat 1.

I kinda thought about this too, basically what you're saying is who's to say in one of the other three chains there isn't an issue.

I had my chains changed on my CNRB when I had the upper oil pan done under warranty. I have maybe 60-70k km on the chains. I am at +1.60°

If you want to be added to the table, post proper details.

Arrh, for the majority of its life it’s been 15k km, but last couple of years iv’e dropped them to 10k km.

After a year it has now started to rattle at idle. Here's an update for vehicle #2. And, just to answer the inevitable question: Yes, I am making plans to change the chain drive now that the end of my dieselgate warranty is approaching.
