Yes, I'm on a stage 2 flash tune with catless downpipes at 80,000km.

Are you using Dinan also ? Yikes....

[mffarrell]

What you have is called bore scoring.

1. Localized thermal hot spots causing the oil film to break down between the piston and cylinder bore.

2. The engine running dangerously close to its' safe design limits.

3. Not changing the oil often enough, as unburned fuel mixes with the oil and reduces viscosity.

4. Leaking fuel injectors allowing fuel to intermix with oil.

Any updates on this ? Curious to see if BMW decided to give you a new engine.
I would want new versus "reconditioned" if it were me.

I am having the same issue as well but I have the JB4 tune. Did you have any luck with BMW? I'm being told I need a new engine as well only at 43k miles.

Following. Dinan stage 1 tune as well. This tune has to be the mildest of any of the tunes - BM3, Carbahn, JB4 and customs. I am inclined to think that the Dinan tune is not the cause. Dinan full exhaust certainly has nothing to do with this.

The Dinan warranty is only in effect while the factory warranty is in effect. CPO doesn't count.

OP, Definitely strip it down to stock and bring it in. Hopefully BMW steps in with some goodwill.

I'm certainly going to pop my hood and listen closely. Isn't a certain amount of "tick" normal? I'll post a video for reference.

That's normal. When the tick is louder than every other engine noise, then there's a problem. You'll definitely notice it.

Thank you! This thread definitely got me paranoid. The mic on the phone definitely picks up more sounds than I noticed while taking it.

Would agree that sounds like every other BMW / German car I've owned or driven.

I think all of us are probably a little paranoid given the two recent posts like this.

OP - truly wishing you the best of luck. I can imagine this is pretty frustrating.

I guess this is why on the TU3 they added the following updates:

* Electric arc wire sprayed cylinder walls
* Piston skirt coating

I was wondering, how long do you think the spray / coating lasts?

I was just thinking of ceramic coating (I know not the same) lasts a few years, maybe just long enough to get past the warranty?

Yeah, I am not convinced BMW introduced these two enhancements on the TU3 as a direct relation to what's going on here. The TU2 has been installed in the 7-Series since mid 2015 for the 2016-19 MY's and in the G30 M550 from 2017-2019. Scorching of the cylinder walls has not been anywhere near a common theme or common complaint or we would see a lot of these 7 year old 7-series breaking down. Although, these seem like nice enhancements and worthy coatings.

I do a flush every other and a Liqui Moly CeraTec (Ceramic) treatment with every oil change. At the end of the day, the same principles in place for 100 years - quality and frequent oil changes help to minimize engine failure and promote longevity. Not saying the issues in this thread are due to lack of quality and frequent oil changes, but some things never change with regard to oil.

And more.......

Electric arc wire sprayed cylinder walls
Piston skirt coating
Crankshaft re-balanced with new main bearing shells
Forged rods from S63TU4
Larger turbochargers with electrical blow-off valves
Updated ignition system, taken from modular B series engines

Found a great article that details the TU1, TU2, TU3, etc ...

I think I'll be placing an order for CeraTec in the very near future. My oil change isn't due until July, but I can afford an extra can for 4 months of additional protection... Was going to do this anyway, but dang, these motors seem to be built on the ragged edge. Glad I don't have a tune.

My shop swears by it. You need two bottles for our engines as they take almost 10 quarts. Well worth $50 bucks.

After reading all this crazy shit, i'm changing my oil every 5k miles. I dont care if BMW says its good for 10k. Not risking it !

That's a good move. It's what I've always done. There's no harm in too many or frequent fills of fresh oil.

Don't get freaked out Mark. Issues with BMW V8's come with the territory. Some severe, some easier on the wallet. I've owned many BMW V8's. From the Nakasil issue on the E32 to the timing chain guide issue on the E39 540. The worst has been the TU only and I skipped that on my F10 and went with the I6. The TU2/3 has been relatively problem free, relatively speaking. Don't beat the shit out of it and change the oil.

Thx Joe. I currently have 12k on the odometer and its had 2 oil changes. So i'm on track (somewhat) for the 5k changes. I will use www.ultimatebimmerservices.com for my next oil change and have them add the liquid moly additive. Its an indie shop thats literally 4 miles from me and they have great reviews.

Sorry to Hijack OP ! Let us know what BMW is doing for you when you get a chance.
