My regret (not even a problem) was that when moving from E to F, BMW matched gearboxes and diffs more closely to stock engine torques, which in my mind was a bit of step back, because you could always count on 3 things with BMW gearboxes in the past 1. they did not provided greatest feedback 2. they always had decent of headroom potential tune 3. every-time you changed gear you felt like you reloaded WW1 full caliber rifle. Deposits can cause misfires and power loss. Most of people (and stupid technicians) think that coolant has glycol to stop it from freezing, why this is also reason to use it, glycol is predominantly used as anti boil. ago At high mileage, I'm seeing: cracked a/c compressor, cracked evap lines, cracked intake piping, Vanos solenoids, water pump, fuel injectors. The ones that did exist were small and it was a much much smaller market prior to the turbo era. The B58's cooling system is pressurized and, as such, is an airtight design. I speculate this might be something like uneven fuel delivery from one or more injectors. That could be said for many modern engines. We think the Supra carrying the B58 helps the platform a lot, too. Injectors are getting loud again at 200k so its time to replace them. Whats your thoughts on this? Although, Im not sure if they have anything for the M340i. Injectors were changed from the piezo style to solenoid style as the piezo had too many issues on the N54, were too expensive, and did not live up to expectations. JavaScript is disabled.

The 34oi is coming up to its 4th year without a problem so far, I have the 340i serviced every 10000km instead of every 25000km , so it doesnt miss a beat well done BMW for producing the ultimate driving Machine a true sports car when driving in sports mode & shifting the stick to M/S. Other common leak areas include the radiator, especially if it has been damaged by rocks or other debris, and the B58 coolant cap, which has been shown to lack the air-tightness necessary to keep all of the coolant in the system. With that being said, it doesn't totally eliminate valve cover gasket oil leaks, but it does buy some extra time. We've seen some VANOS problems with the B58 engine. Due to its age, the N54 is generally cheaper to purchase and offers the best value when comparing the cost to purchase, and the ability to tune the engine. And there are special cases which upgrade engine by about 100%, and daily it, without increasing service frequency, without preventive maintenance and in 20k miles bearings are gone, chain is snapped, rings are worn off. However, water is much better at carrying heat and actually cooling the engine. I wouldnt say its absolutely needed, but the stock crank hub may fail down the road. With that being said, there are some shared issues between the three engines, like VANOS solenoid failure and oil filter issues. Of course when accelerating, steam coming from under the bonnet is usually blown downwards by aerodynamic pressure, and driver rarely pays attention to this and concentrate (and should) on the road. Had n55 in a 2011 335cvt, w manual. Washed my hands with it and looking forward to my next car (not BMW).

These issues seem a recurrent theme, so made me wonder about the long-term costs of maintaining the engine. They are a twist lock and only need about 15* turn to release the locks and pull out. Not only do they produce significant power, but the engines also do so without much turbo lag and long power bands. We did not include that as we do not consider carbon build-up an issue. If possible, How much would it cost? Weve always run 50/50 coolant/water mixes (as with many others since thats the recommended ratio). Now I still experience a bit of coolant loss, but much, much less. We use cookies to improve your experience on our website. I too have had the coolant loss issue. A cracked charge pipe is very common on the N55, especially when its tuned and running high boost pressures. Stupid technicians, or cheap skates that mix coolant with distilled water cause cooling system boiling point to fall. Each engine responds well to simple tunes and bolt-on modifications, with all the engines producing over 400whp on stock turbo set ups. Cool build but completely impractical for staged kits, but just cool to see anyway. I just bought a 2017 April F20 M140i x drive and I am If youre having any warranty work done youll probably want to remove the JB4 tune to error on the side of caution. 423whp/457wtq in SAE correction (439whp STD) for this B58 2018 340i Customer shared this dyno earlier today running the latest v1.6 Stage 2 93 octane (98RON for those in Europe) OTS map. Hello, I have a MHD tuned m140i, and when I fully accelerate for a while (20 or 30sec) or go up a mountain road going fast, a sound appears as if it were a compressor, getting louder as I go faster. Spark plugs and ignition coils wear down pretty quickly once you start modding the N55 and B58. Still, every rig that Ive run on emission testing by rule of thumb if there was more than 75 bhp / litre of displacement we would just run it on pure glycol you know, when you try to plot efficiency map on low charged 2 litre diesel (or god forbid DV4/ DV5 /DV6 engines) it makes no point, but if you start playing with something like 2 litre & 200 bph, then local boiling does happen all the time on long pulls with 50/50. Space is very limited but its doable. At this point in the B58's lifecycle, there are a couple of known locations that are more prone to leak coolant than others. AND BTW, I dont know whenever new caps will fix anything. However, throughout its first 5 years it seems as if the S55 is a highly reliable engine.
