2015 335i - Turbo Leaking. Dealer says it is normal!?
I have noticed that there is a leak coming from the bottom of my turbo and dripping onto the subframe below. It is coming from this clamp that is on the turbo which looks to be on the intake charge air side.
Car is still under original factory warranty. This picture shows the location on my turbo (my car is EWG): Picture attached. https://imgur. com/gallery/sJNsaEy Dealership Visits 1st visit: Claims it was residual oil from when they replaced a leaking turbo oil feed line. However, the area and the subframe below was cleaned from that previous visit. They again clean the area and subframe and told me to drive on it. 2nd visit: 5 days after my 1st visit I return because oil can be seen and felt again dripping from that area on the turbo. Long visit debating with shop foreman with the car on the lift and him showing me it was a "small" leak which is considered normal seepage. Wanted me to agree to disassembly where if they did not find anything wrong with turbo, I would pay the labor. Back and forth some more, how is oil leaking from a turbo considered normal? Finally agree that he will clean it up again and take documentation. I am to drive on it and bring it back if it leaks again. Took it to the local mountains (San Gabriel canyon road is right next door...) to beat on it and have not noticed any oil leak yet. My concern: I'm worried he just cleaned up the area and tightened that clamp down. Looking below the car, he even marked the under tray bolts with yellow wax to detect if anyone removes the under panels. This does not solve the underlying problem that there is an oil leak internal to the turbo that seems to be leaking out the intake side clamp (turbo seals?). This oil is likely traveling through the entire intake track: intercooler, throttle body, and coating intake valves. Maybe that contributed to the occasional rough/shakey cold starts I've been having before they replaced the 2 engine mounts. Car is still under original factory warranty so why make it so difficult. They seem reluctant to go to BMW to cover this warranty work, claiming it is normal seepage and BMW expects to see a larger leak before any work is approved under warranty coverage. I think this is unreasonable when I can reach down from above the engine bay and touch the oil that pools under this turbo clamp. Is that not sufficient proof?

So if you weren't within warranty, think they'd suggest parts be replaced? Some of these dealerships make me sick.

So, i'm in the business (Fixed/Service Director for multiple franchises 23 YEARS) and the following is true:
1) Manufacturers do stipulate that there are two types of leaks, normal seapage and what would be referred to as an active leak. They do not allow repair on normal seapage. WITH THAT SAID, IF IT'S DRIPPING, THAT'S ACTIVE. 2) There are many dealers out there that do business correctly, find one that does and give them your business. 3) Keep in mind, dealers get paid great money by the manufacturer to administer warranty repairs and keep you happy, it's in their best interest to do both... GOOD LUCK

I'm thinking about removing the charge air pipe connection on the turbo to intercooler side, which should allow me to inspect the intake compressor side of the turbo for any oil leakage. It seems to be feasible to do from the top of the engine as looking down I see some room to work with. Does any one have recommendations?

EDIT: https://www.quora.com/Is-it-normal-f...RPMs-regularly My understanding is that the turbo seals are supposed to contain this oil within the turbo bearings and from blowing into the intake or exhaust side (?) |

Have you tried taking the car to another dealership?

Oh gotcha, he is referring to combustion blowby and the PCV system. Where in the intake track is the PCV blowby injected back in? Before the intercooler or after the intercooler? Is PCV blowby injected into the intake downstream of the turbo? In which case there shouldn't be oil on the compressor side of the turbo. I tried searching for a diagram of how the PCV system is routed in the N55 motor. EDIT: Nvm, looks like PCV system injects back in after the air filter and before the turbo charger, so blowby oil will be present on the compressor side of the turbo. =\ Last edited by ctbear; 05-12-2019 at 02:52 PM.. |

In my own case I wanted a tech with certain experience to do warranty work on my car. A high level person who used to work at the dealership told me not to bother making that request. He said that the jobs are always just assigned at random to whichever tech is next in line. He said that it was more important that I used a certain Service Adviser who was dedicated and would make sure that it was done correctly. It's just insane that both the BMW dealer hourly rates and the # of hours listed in their book for each job are so ridiculously high. The quality of work should be equally high. Hope that you find a solution. |

Oh, if you have a choice, pick a dealership not owned by the same person or group, just in case it is some particular ownership policy that is causing the action that you are receiving. Good luck! |

A brief story: I had a 2009 Infiniti G37 and while it was still under factory warranty, it started behaving very strangely -- constantly trying to "start itself" (it couldn't as it was a manual) and, when running, constantly shutting itself off. Took it to the dealership closest to me, they informed me it was the alternator. They had the car for 2 weeks. To replace the alternator! Absolutely insane. Communication was horrible. Luckily I was in a nice loaner so it wasn't that big of a deal. I go and pick up the car and on the way home it starts doing it again. I take it to another dealer (35 minutes away from me, but with slightly better reviews). The SA at first didn't want to touch my car as the first dealership "does bad work and we don't touch their fuckups" (his words). I pleaded, and told him the problem. He checked it out himself and immediately went "Oh. It's a PCM module. We'll take care of you" Later that day the car was done and the problem was ACTUALLY fixed. Here's my point: it took one dealership 2 weeks only to misdiagnose and incorrectly repair the vehicle. It took another one 5 minutes to diagnose and 4 hours to repair the SAME problem on the same car... ...This is just one story of many unfortunately. There's only one Fiat dealership within 100 miles of Chicago that I'd let work on my Abarth, and frustratingly it took me going to 4 dealerships before I found it.
