Default Washer Adjustment for Front Turbo - E60 535i with Dynamic Drive - 12-19-2019, 12:49 PM

Fellow N54 boosters -

Long story short, does anyone have experience doing the washer wastegate adjustment on the front turbo of an E60 535i with dynamic drive.

I am trying to track down a 30FF code. I have lots of wastegate rattle and dealer says the front turbo is done. I replaced both boost solenoids which helped but still get lag and the code under hard throttle. Next up is vacuum lines and TMAP.

I have heard that the washer adjustment on the front turbo wastegate actuator housing is the best way to adjust the play in that wastegate...on the 3 series...since the arm itself is impossible to reach. I have watched some videos and feel like I could do this myself. But my indy (who I trust) notes there is no easy way to gain access for that adjustment on my 2010 535i because there is so much in the way, including the dynamic drive sway bar (ARS). To get there would require several hours of labor, the cost of which brings turbo replacement into the picture.

I'm hoping to avoid the big ticket for a little while longer. Any input is appreciated.

Thanks,
John

Save yourself the time and headache, just replace them. These turbos are hell to get thru on a rwd,I can’t imagine a xi with dynamic.

I've done it myself on 335i on ramps in my garage. Pretty easy once you find the right position for your hands. Took me about 2 hours. Not sure about 535though. Rattle disappeared completely and still not there after 20k. I wasn't getting 30ff, but spool is also much faster.

FWIW, I am RWD.

Maybe I can get there by taking off the wheel well liner.

Replaced some vacuum lines and then took a look underneath yesterday. Think I've found the source of my boost errors. Ug.

Isn't that your inlet with the puncture?

I think that's just a smudge from the RB logo. It's more that the inlet is moreorless of off the turbo snout. I think that is why I'm getting under- and over-boost errors.

Shouldn't affect boost should it? Not part of the charge system. However I could see it allowing MORE air than expected to enter the turbo, but having it allow more air and less restriction should let the turbos run at their maximum efficiency. Although with the chance of sucking in debris and ruining them of course.

Inlets coming loose is actually one of the things to check for in the case of 30ff. I saw it in the service bulletin that someone had copied in a thread somewhere. My theory is that it's easier to condense air if it reaches the compressor wheel inside a confined tube that is sending air onto the wheel.Rather than pulling unrestricted air from outside the tube.

Of course, it could just be that the wastegate(s) are worn to the point where one or both cannot seal. Dealer said the front wastegate was toast. But I just had both checked about 6 weeks ago, before the boost started. Rear was closed at 5 Hg and the front at 7Hg. That's why I'm leaning towards this inlet as my issue.

This is incorrect.

Well my indy smoke tested and found a leak at the intercooler coupling. Between that and re-attaching the rear inlet, I'll see how it drives shortly. If no good, I see the an attempt at the washer fix on the front actuator in my future. Still hopeful

A little improvement, but nothing close to normal. Indy took time to explain and field my questions. He suspects that this is not the wastegate at all, but bearings are gone and I'm hearing fins scraping the housing. He may be right. When I first the noise I thought it was different from wastegate rattle. He stated most stock N54 turbos crap out at 50-60K miles. Mine are at 60K.

Damn, I wanted to put this behind me. Now I've got some decisions to make.

Ive done the washer on the front turbo of my e60 way back when i was on factory turbos. It can be dont from the top. Its not easy but pull the coolant reservoir and vacuum canisters for more room. with patience you can get it.

Thanks, Tuppidsay.

At this point, I feel like I might have missed the window. The washers seem like a very short term fix and I am sooooo tired of the rattle, lag and 30FF. I'm just about to pull the trigger on a set of RB Ones and get back to driving enjoyment.

For me it toned down the rattle but the big thing was the lag. Its a band aid at best. New turbos is the best choice hands down.
