You can guess which is more expensive! And industry efforts to self-regulate have always floundered. Carbon naturally builds up inside the engine, but this carbon is typically burned off when the engine is ran hard and heated up to high temperatures. This post is going to cover the most common N54 engine problems, along with the symptoms and error codes to be able to identify them. Still bewildered, I called a trusted auto-body shop and it recommended Steve Zorbakis, who runs. The gaskets on these cars are very prone to withering away and degrading over time, which results in oil leaks, and a buildup of oil in your engine. My rear tires have leaked since the car was new, but got significantly worse lately. No pot holes were hit and the car was barely driven.
If you would like to write a letter to the editor, please forward it to. This technique uses walnut shells, and blast theme at high pressure into your valves to completely wipe out all of the gunk. Perhaps what bothers me most is the high level of dishonesty I am encountering. The 335is is an N54 sport version of the 335i that was made from 2011-13. Upgrading your chargepipe is a good preventative modification. Hopefully you fall into this warranty. Why would I spend tens of thousands of dollars at a dealership that treats its customers in a such a shoddy fashion when something goes wrong? I have already replaced the run flats once and drove less than 10,000 in this car.
When the engine cools down, the carbon can get stuck inside the engine and inside the injectors, causing clogging. I returned to the dealership and was informed that the tire was shot and that the rim had cracked which it had. Last night I was on the freeway coming from Vegas and where they were working on the pavement, there was a smooth suface then a rough surface. The discount shop looked promising. The cheapest companies may offer a lifetime guarantee, but they often aren't in business when problems arise down the road.
The problem is exacerbated by the run-flat tires, which are very hard and have strong sidewalls resulting in too much of the normal road force from small bumps being transmitted to the rim rather then absorbing some of the shock in the tire. But I promise most of the others are. The fuel injectors are responsible for spraying the spark plugs and with gasoline, so that they ignite on start-up and every revolution thereafter. Replacing the turbochargers is extremely expensive. Walnut Blasting your N54 to Remove Carbon Build-up Once your N54 hits roughly 45,000 miles, it likely has a good amount of carbon built up inside of the valves. This is replacement is usually 15+ hours of labor. My wife had a leak for a while and kept driving and adding oil.
Give the dealership a little push and shove and they will replace all of them. Aside from clogging fuel injectors, carbon buildup in the N54 can result in sluggish performance, and misfires. The leak dripped onto the serpentine belt. Direct injection shoots gasoline into the cylinder, instead of the back of the valve. If it is a clogged injector, you can follow the maintenance steps below to help solve the problem. The real concern, Zorbakis said, is other materials used by installers and the skills they apply. I abuse my car and it takes it like a Champ.
Water Pump Failure The water pumps on the N54 engine are another fragile piece of equipment. And they wouldn't allow a car to be driven before that time. They have come a long way since the first shoddy ones came on the market years ago, and are now the norm in the industry. Instead of offering to replace the broken clips, they had covered it up by gluing the mouldings where the clips had broken, using the windshield adhesive. Carbon buildup is a result of Direct Injection fuel systems, which as the name suggests, injects gasoline at high pressures directly into the combustion chamber of the engine. Pop the coils out and inspect them to see if they are coated in oil. This is a space where subscribers can engage with each other and Globe staff.
If you still are unsure, pull the plugs and look for oil on the spark plug threads, but not on the electrode the tip. Ironically, the week before this happened, I had been talking to their sales department about possibly trading in my 2006 for a newer model. Thank you for the comment, Sdub. The covers are plastic, and therefore are affected more by the increased heat created by turbocharged engines. I have a claim with my insurance co open on this issue so they are paying for it, although something tells me this may have nothing to do with the claim.
When the injectors leak a considerable amount, this will make the spark plugs very wet, which will in turn make it harder for the engine to ignite the spark plug and start the engine. The easiest, most effective, and most efficient way to remove this carbon buildup is through walnut blasting! What is an N54 Wastegate and Why is it Important? I had never seen anything like this in my life! Therefore the valve and the ports do not get cleaned by the gasoline and other detergents as they normally would. I must note that the frontline service rep, Marco, was very polite and tried very hard to be helpful but he did not have the authority to overrule Tim. How to Fix N54 Wastegate Rattle: Repair Options The turbochargers are warrantied for up to 10 years or 82,000 miles. As a result, water risked getting under the top, and popping the seal or cracking the glass when it froze and expanded in winter. Over time the actuator and rods of the turbocharger wear down, resulting in rattle and boost control issues. Why do N54 Fuel Injectors get clogged? New videos are always being uploaded every week! The tire shop put the wheels under water and we saw bubbles coming out of the cracks in the wheels.
Read on to learn the symptoms of Wastegate rattle and learn how to mitigate the chances of it happening to your N54. Direct Injection systems allow for a lot more precise fuel measurements think air to fuel ratios, etc. The Wastegate controls the outflow of exhaust gases away from the turbochargers. Clogged injectors can also cause a bad fuel spray patter. I risked having a windshield that could fly out in a crash because I was allowed to drive away too soon after the installation.
I specifically asked them to check the rims and was told that the rims were carefully inspected and perfectly fine. It seemed apparent to me that he had been through this problem all too often before and did not want to deal with it again. However, it is tough to diagnose without seeing the car in person and testing for codes. But not as responsive to mods. In this case, running higher levels of boost psi on your turbochargers will likely increase your chances of Wastegate failure. Chinese-made windshields are fine now, he says. This procedure can be used to repair existing damaged trim or make custom trim.
