Will you not buy that truck if the answer is "YES"? EGR and DPF problems were never solved on the pre-SCR ISX motors - replace coolers, turbos, dpfs etc as they go is all they have. You might get lucky though, some run just fine.

I was just in Amarillo at a Freightliner dealer and they replace a lot of failed, emission related parts on the DD15 motors - seems mostly sensors or filters go bad so maybe they have a better design? They haven't made a quality truck since the FLD/Classic though.

Is this the best info out there? Really? If this is it, perhaps 2009 and newer are ok? I am planning on buying a 2009 Pete 387 with 385k miles and a brand spank'n new dpf. Does anyone have any thoughts on the matter?

Update

It is fleet return from Prime. No maintenance records available other than the recent work done by Rush Peterbilt in Phoenix. The DPF was replaced because I asked to have it checked out and it it had a crack. So the new DPF has a 1 year warranty. It has been dyno'd which looks good. The ECM download shows very few faults, nothing pertaining to the EGR. I would buy a Premium 2000 Warranty as well. I am a little nervous as it seems as if all California CARB 2008-2010 trucks have potential problems. How do you "pull off" all of the emmisions equipment and stay compliant? (is that a stoopid question?)

Company i used to drive for had 2009 and 2010 ISXs with EGR and DPF...none were trouble free. It's nothing more than a gamble with those motors. I love the ISX but wouldn't own one unless I spent the money to pull off all of the emission equipment. Have you checked how many EGR coolers and turbos that truck had replaced? Is it a fleet return or an O/O truck? Any camshaft issues in the past? What info do you have?

If the emission stuff gets pulled off the truck is out of compliance with CARB and the EPA - but you'll have a long and great running engine. Since you need a truck for Cali (?) you are in a pickle. Some faults that seem unrelated stem from emission equipment. If you're pretty set on that truck have the dealer inspect the cam at his cost (simple and short job). I doubt you can get a decent oil sample - that's probably fresh. I would strongly suggest a pre DPF ISX with just the EGR and run with it unplugged - that'll buy you a few years before you need a DPF. If you look around you may also find a pre-EGR ISX. IIRC those were produced from 2000 till 2003? And when you have to retro fit it with a DPF - no EGR. Overall, try to get as much time from an engine with the least emission equipment required.

There's a reason that the truck has a 'brand spank'n new dpf.'

More than likely this truck is having classic egr issues...before buying this truck...request that you see all maintenance records. ALL of them.

I have a 2010 KW with a 09 ISX 525 HP. I haven't had any DPF problems but had to replace a turbo at 275,000 but it was covered by warranty. I am about to take the truck to PDI and disable the EGR and DPF, upgrade exhaust manifold and turbo. I don't mind taking the small risk of getting caught in California.

I leased a 2009 387 with an ISX 400ST. Put 290k miles on it pulling beer out of Golden, CO and loadboard freight coming home. Ran that truck hard for two years with no problems but never broke 6.4 MPG on fuel gauges for a 30 day avg. Truck had wide singles w/XDAs and XZA3s up front so rolling resistance was low. truck was goverened at 65MPH. Our trailers were all smooth sided with skirts and wide singles with low rolling resistance as well. I loved that truck and the pulling power but thought the MPGs were a little low. I think Detroits are closer to 7mpg avg.
