Just curious, and if so, how many miles? Also, where can I buy block plates? thanks Gentlemen. I have 25K and no issues, but want to block EGR before it becomes and issue.

[WreckerX5d]

73k miles, just got my car back yesterday from a 2 1/2 week long CBU/injector fix.

iaknown sells the plates.

[dixy2k]

yes. started at about 50k, many parts replaced and finally at 62k the official word is I need a clean up. It wasn't done initially (just a lot of parts were replaced).

[2deerwhistlers]

Yeah duramax talk to Iaknown .. He's got what you're looking for.. Ive been rocking his block off with my dpf delete pipe and ecotune touched my ECM

[crugeman]

So far I have not had any problems. Just ticked over 60K on my '11.

It would be good to know what is done by everyone regarding risk factors for CBU.

Fuel brand? Additives? Heavy or light foot? Oil change interval? Strict use of LL04? Electronic engine management recall done?

I have had no issues, but notice a steady decrease in mpg - could be my driving style changed, but... I did need a fix of burned out catalytic converters and fouled NOx sensors which happened after I used a fuel stabilizer additive and changed my driving style to one which would normally (in my past cars without a DPF) cause a cloud of black smoke on flooring/downshifting strongly. I believe I dislodged too much crud and put it into the converters which burned them out. Now I routinely do a strong downshift to clear out the crud.

Now at 42,000 miles, 50/50 city/highway, daily local trips. No additives. Mostly Texaco diesel.

43k and still running good so far

[dubulup]

just rolled over 50k...had CBU around 43-45k...car was in the shop multiple times longest being 120 days for the media blasting.

Dealer extended my warranty (highest one includes nav) to 100k/7yr no charge

Four months?? I have never heard of any brand that has had this sort of problem. Mine was in for only 94 days!

55K just had CBU. Cleaning took 1 week. Would have been ready sooner, but gasket was on backorder.

[modobrew]

just dropped mine off this morning. Injector 2 code. Waiting on my SA to call me and give me the update. Also having the fuel filter replaced while its in there. Just a tad over 66k. LL04 at every change.

[AzureHaze]

41k and still good!

[BB_cuda]

32k and all still fine. No performance or mileage degradation yet. I'm told the performance change relative to CBU is slow to notice thing. So, I might not be noticing. Block off kit going in when "other" ecotune work happens shortly. I have intentionally not been driving the car since beginning of year. My daily commute is short (4.2 miles each way) so I'm a prime candidate for CBU. I've been driving 2003 truck back and forth to work and use D for longer/higher speed trips to minimize build up (hopefully).

[skychismo]

I bought mine with 34k on it. The SES light came on the second day I had it, and it's been at the dealers since then (going on two weeks) for CBU issues.

[duramax]

Crap, thanks for the info guys. I am going to buy the block plates and look at the DFP delete and code after the warranty is up.

UPDATE: Just got word from my SA, replacing 6 fuel injectors. we'll see how long that fix lasts.

For over 18 months, I got a recurring SES light, injector #2 and #4 zero quantity limits codes. I had a total of 2+2+6+6 = 16 injectors replacement and that did not fix the problem. Currently, my car is at the dealer for 1 month now, they are trying to fix it. For me the multiples injectors replacement did not fix anything.

Before someone ask me: No they did not replace the DDE.

Yeah, I mentioned that to my SA and she said they just recently finished doing a cleaning to one for CBU. I also mentioned the DDE and she said they done that to one as well. They went ahead and did 6 injectors to save me the hassle of coming back in to have other done and having to pay the $50 deductible each time. Only time will tell....

[montr]

I keep track of everything fixed and replace on my car in a spreadsheet. New parts are guarantee for 2Y. If they fail during the warrantee period, I do not have to pay the $50 deductible of my extended warrantee.

That's how it all starts.

Got mine back from the dealer today and the SES light came back on eight hours later...
