Walnut blasting 335d

Si-M240i · 10-09-2014, 01:12 PM

Well this will be controversial I'm sure. Flame suit on.... My local BMW independent specialist who does walnut blasting says he has never needed to do a diesel or been asked to. It is only a petrol engine issue. I guess as I was running 380bhp at 35k miles I didn't need it then and the car only seems to be getting better at 45k miles.....thoughts anyone?

taibanl · 10-09-2014, 01:21 PM

It's not controversial, its just simply wrong.

If you personally don't need it, great! Your fuel in UK is better and your emissions system less intrusive/problematic (EGR)

Hoooper · 10-09-2014, 01:42 PM

Most in the US probably havent been asked either since it manifests in a wholly different way than the gassers do. The diesels throw a bunch of codes and start to run poorly seemingly out of the blue for most people. The gassers dont do that until they are REALLY bad. I would bet if you asked the indys in the US most of them would say the same thing. It does seem like you guys in UK have fewer issues though, cant help but wonder if the EGR was not cranked up so high there

Valid points I see a lot of you guys over the pond having issues and posting nasty pics. I have always run my 335d on she'll nitro so maybe that has helped. I a also change my oil every 10,000miles

I think the fuel has a lot to do with it. I finally found a Shell that sells premium diesel, so I've been using that. Everywhere else just has diesel.

Pierre Louis · 10-12-2014, 12:13 AM

I know people that work for Shell and in the past other engineers. Its European and has, in some parts of the US, its own pipeline (vs the local "distiller" ha ha). I doubt there is only enough detergent and other qualities just to get by. They are in business and cannot lose customers by supplying an inferior product. They do not sell crappy fuel while what I have heard from owners of non-brand name stations often do.

This may or may not have anything to do with 335d problems or lack thereof, but I'll bet that it does.

Everything I have learned by calling distributors in the Baltimore area is that most or all stations use the same general fuel but the additive package my differ. (And that may be a significant difference for some.)

kbsilver · 10-12-2014, 01:18 PM

I was under the impression that Diesel had little to no additives (being very different than gasoline). I know they blend in some kerosene in the winter so it will flow at lower temperatures.

Additive by the fuel supplier is critical and apparently tailored to the base stock, which varies quite a bit.

I spoke with an SA at the BMW dealership. He told me that brand name (Shell, Chevron, Exxon etc.) fuels are filtered better than the "off-brand."

I can only say that most of my diesels like(d) Chevron. BP and Shell diesel somehow didn't cut it, causing occasional rough running but never Chevron.

Might be psychological, ha ha. Haven't been treated to the CBU debacle yet and I keep my DI diesels a long time. Did have one injector fail on my old CDI (injector #1 gets more thermal variability being in front).

This I agree with. My approach is to only go to major brand stations that move a lot of fuel so I know it's fresh. My one exception is to purchase fuel from a fuel oil supplier very close to my house that does a lot of volume. They have truck racks, deliver fuel to construction equipment, have off road Diesel, kerosene, etc. Prices are good and the car seems to like it (seems to be better MPG). They pick it up themselves in their own trucks every few days from the depot.

Pierre Louis · 10-13-2014, 08:26 PM

Got a call from the regional BG rep about my inquiry. He will supply private mechanics with the additional tooling required to do BMW diesels. I told him I would be maybe doing it early next year, but he was going to supply them anyway. He even knew who the mechanics were in the area.

Hi everyone, new to the forum but wanted to see what the experience has been if you've had your car walnut blasted. My 335D has been in the shop since 11/1/14 with no end in sight. Apparently there have been further complications with the car continuing to throw codes and BMW NA engineering has been brought in. I don't mind the '14 328i x-drive loaner however I do miss the diesel.

Prior to this service, a faulty injector was to blame, replaced and rough idle continued.

Anyone had their car be a service bay queen for a crazy duration and who to push to get the issue resolved?

Thanks!

dixy2k · 12-16-2014, 09:16 PM

There are people here that could've had a baby while their car was at the dealer.

The dealer had my car in the shop for a total of 3 months in 2014!

Here in Puerto Rico Puma Stations are running the cleanest DIESEL on the island , guess how I found out, was speaking to my old high school buddy that HAPPENS to be one of the big bosses of Puma( I didnt know he was the one of the bosses) here on the island he told me that their product is by far the best on the island and he even challenged me to it, and one of his customers is the U.S. Coast Guard so one of the quality managers when he was active is a friend of mines , me doubtful as usual called my friend the ex bass fisher and asked him and he confirmed it. Puma stations have the cleanest DIESEL in the island so now Im using their product enough said

PR. You can't just trust everything people say.

Any data on the diesel? Cetane? Additives? lubricity?

It's like someone telling you this scoop will have 10 more hp because it's red (sorry). Data is the truth, but even it can be made to lie.

And you trusted the leprechaun? I've seen the movie the tooth fairy and he did not smoke crack in it. Hollywood has to be right with their fact.

My car was in about 2 months ago @ 53K miles for an SES that was due to CBU. While the SES was for an injector & rough idle, there was nothing wrong with the injector, it was CBU. CBU cleaned, no injectors replaced and car runs perfectly. I brought the car in with the knowledge it would be used by BMW engineers to gather more information about the CBU issue which added a couple of days. I believe the point was to develop better CBU diagnostic procedures. They had the car a little over a week.

dixy2k · 12-17-2014, 10:02 AM

To OP
Your mechanic probably has not seen too many high mileage diesel BMW's.
On Youtube there are a few shops advertising CBU cleaning and a bunch of private videos wit DYI. Start with youtube and extrapolate from there.

There are 100k + 35d's in the UK and to my knowledge still no CBU issues. I'm approaching 50k and my car pulls like a train with a rock steady idle still.

All I run is Shell Nitro (Diesel VPower) it is supposed to have excellent clean burn and cleaning properties as well as high cetane levels and upper cylinder lubrication. Maybe this coupled with the fact that emission control is very different on the UK cars to the US, is why we are not seeing the same CBU issues in the UK.
