Herbmiester 927 Report post Posted January 26, 2020 So I was helping Boytie with a Stage 1 MHD tune on his 2014 M135i. Everything went very smoothly and as we took it for its first run there was a pop sound and warning flashed up on the screen. A quick look under the bonnet revealed that the factory charge pipe had exploded where it meets the MAF. Now I know N54s are notorious for it but was surprised that a basic stage 1 tune would pop it, especially on a low km vehicle. Anyway I am looking for a charge pipe, any recommendations on who might have one in NZ? Poor old Mark has to slob it in my Toyota until I get it sorted.

blake12 23 Report post Posted January 27, 2020 No one should be upping the boost on their n54/55's without upgrading charge pipe first. The pipes have gone even on stock tunes. Best bet is trademe if you want one without waiting for overseas shipping 1 Quote Share this post Link to post Share on other sites
brenthay 10 Report post Posted January 27, 2020 I bought one from Ali Express for my n54, was cheap and quality was good. Have had it on the car for over 5000km's and no issues so far. Quote Share this post Link to post Share on other sites
KwS 2425 Report post Posted January 27, 2020 I still dont know how my Stage2+ N54 was running the stock charge pipe.... Obviously had all the hopes and dreams. Quote Share this post Link to post Share on other sites
Dom. 5 Report post Posted January 27, 2020 I have my OEM N54 chargepipe from when I took it out. Around 40,000kms on it. No idea if it would fit but let me know if you want it Quote Share this post Link to post Share on other sites
BlackrazorNZ 83 Report post Posted January 27, 2020 N55 chargepipes are notorious for blowing, even on factory setup, and often with as little as 30-50k on the clock. To the point it became one of those 'expect to have to fix it under warranty' issues for new buyers. Quote Share this post Link to post Share on other sites
Matth5 471 Report post Posted January 28, 2020 Mine blew just with the BMW PPK tune. And nobody in NZ had a replacement in stock at the rime, stock or aftermarket... The CPE/BMS one is good. Make sure to get the o-ring too if the original disappeared when it blew. And c-clip if you lost that. Mine was resting on an undertray panel behind the engine.

Herbmiester 927 Report post Posted January 29, 2020 Thanks all, I found one at https://www.nzperformancetuning.co.nz Looks to be well made, comes with a new clip just in case the old one isn't on the under-tray. Having blown the CP on my N54 335i I am well aware of charge pipe weakness what surprised me is that on the F20's the pipe is different and supposedly upgraded and is also used on the M2 so i thought it might be a bit stronger, apparently not. Anyway will fit it tomorrow and get the boost back. 2 Quote Share this post Link to post Share on other sites
