I’m at 84k and I have zero issues also. Forums tend to make u paranoid tho. fuckin BMW trying to be all techy and shit. Why couldn’t they just have used a regular crank-driven waterpump instead of some $500 electric water pump b.s. I’m sorta liking the accord sport lol. ---

> [@Clean Baldy](#): > > Well, I hate to join this thread, but my 335 started to hesitate when giving it some throttle and hitting boost. It then threw a CEL, so I brought it in last month and it’s been back twice so far this month, with a 3rd visit coming soon. > > They initially just replaced the low pressure fuel sensor, which got rid of the CEL. Sadly, the hesitating didn’t go away, so I brought it back. On my second visit, they replaced all of the injectors and the HPFP (3rd time) and it STILL isn’t right. It feels like it’s running smoother, but at that 3k-4k mark, it still hesitates and is jerky. I had asked them about the weird rattling that I’m pretty sure is the wastegates, after reading this post and watching some youtube videos of wastegate rattle. My car definitely has that noise, but they’ve been telling me it’s the injectors. > > Now that they’ve replaced the injectors and the sound is still there… I just called them again and left a VM. Bummer… I don’t like that my car needs to be taken apart this much just to fix my strange power issues when my car hits boost. > > I feel like it could be the computer hiccuping when the turbos start to spool at 3k. Or, the turbos/wastegate could be leaking and delivering incorrect power, causing it to hesitate. Hopefully they find out what’s wrong with it soon. ☹ > > Goff, if you’ve been working lately, I bet you’ve seen my car… it’s a red '08 335xi sedan with 18" wheels. You should be seeing it again soon… perhaps you can take a look? Sounds like either carbon build up on the valves or the cats are clogged up if the injectors were sticking open before they were replaced. Could also be the turbos, almost all N54s have some sort of wastegate rattle but they could be worn out to the point of allowing a boost leak/ not building sufficient boost. ---

Thanks Goff. The car has 78k miles on it and I definitely hear the rattle that others are showing in some youtube vids. It’d be nice if the turbos were rock solid, but again… with this weird hesitate right around 3k… I’m kind of hoping that they are the problem. I just got a hold of Adam and will be dropping it off Tuesday the 21st, the next available day. That’s 2 weeks away… must be crazy busy over there… In the meantime, is there something I can do myself to clean the valves and/or cat of the possible build up? ---

Very easy to do just need the adaptor/wands for the intake ports If someone gets in done in an hour they are not doing a good job. Took me better part of the day to get them spotless.

> [@Jeller](#): > > How messy was it using the walnut shells? Are they eveywhere? It really wasn’t bad, next engine bay will be taped off fully with plastic. Lets just say the garage is full of them. I got the vacuum in and got most of them out. Had a moment of mis communication with my helper, he turned the air on before the wand was in the valve, whoops! Mine were pretty bad, really hard to get pictures but ill post a couple. Lots of blasting, scraping with a pick to get off weird angles, some carb cleaner, and re blasting. But over all im happy with them Starting off [ATTACH=CONFIG]23757[/ATTACH] Getting clean [ATTACH=CONFIG]23758[/ATTACH] Clean! [ATTACH=CONFIG]23756[/ATTACH] ---
