Hi everyone, This is my first post and I hope I dont p*ss anyone off with my lack of knowledge on the topic :). So I have driven my 1er for around a year now, and have noticed that in sport/sport+ when producing a good amount of revs and releasing the throttle, there is a "dump valve" sort of...

Hi Guys, Recently bought a 2006 bmw 335i with 63,000 miles the day i got it i heard the wastegate rattle ( on start up and on deceleration) and confirmed it was indeed the actuator by turning on the engine and applying pressure to the actuator. There is a good bit of play in it, so armed with...

Hi Guys, So I have an issue with the actuators on my 335i turbos. The garage has taken the turbo's off my car as I requested them. The actuator seems a bit loose but nothing more, but I've been told that the arms and bushes on both turbos prevent the wastegates from closing. I've rang up a few...

I purchased my 335i in February this year, and soon noticed that on cold startup the turbos were rattling away. As the car had FBSH and extended warranty, I decided to take it to BMW, pay the excess and they replaced both the turbos. However, after completing just under 2k miles, there is a new...

Yesterday I took the liberty of replacing my thermostat, whilst doing this I cleaned out the egr valve and inlet manifold opening, after what I thought was a good job well done I started up the vehicle and took it for a drive thinking that removing the crap would make it drive better.... But no...

Hi iv had a problem with my E46 320d where it feels like a limiter cuts in and the car has no boost and won't rev over 3500 so done the usual shit EGR, VAC pipes ect ect couldn't find the fault so I took it to a diesel specialist who after a week diagnosed it as having a wastegate fault he said...

Hi guys, I wanted to pick your brains about a problem i'm having with my engine and it's lack of power 1 in every 15 journeys or so, it's very random so hard to approximate. I've narrowed it down to the turbo wastegate actuator, I believe it is sticking open and not allowing the turbo to do...

Hi There I'm new to this site but wish i'd joined a few years back when i purchased my 335iSE back in 2010.A year later a small rattle started which sounded like it was coming from underneath the car and wasn't that loud so didn't really bother me but after a few more months,especially in the...

So I have a 57 plate X3 2.0D. Brought it 3 years ago from main dealer and have covered 25k in that time. Just recently had a problem with power dropping off and the car going into limp mode. Faults came up saying EGR valve, turbo and air mass sensor. BMW took in and diagnosed EGR valve which...

Hey guys, So i think im starting to get the dreaded Wastegate rattle on my out of warrenty 335i, i called up bmw to enquire into this 8 year 82000mile warranty that iv seen on a few different forums and google searches to be told that there is no such thing. My question is, this extended...

Hi all, hope you guys had a good Christmas and a Happy New Year. Just a quick query, hope somebody in the know can give me an answer. Seems my wastegate or the Vanes on the turbo, whatever this car has, I am unsure, are staying open to around 2000rpm then closing. Under medium to full load...

Guys im looking to buy a 335i. Speaking with the owner asking all the normal questions and he said there is a slight rattle from the turbos/wastegate maybe? He has said this is perfectly normal and is the same on all twin turbo'd Bm's Hes said is been this way for his entire ownership of two...

I need some information regaring actuator wastegate adjustment for bmw 320D M47 engine 136 hp. I think that the ex owner modified that 10mm nut from actuator and now, sometimes i can feel a limp mode because too much pressure, and sometimes a little turbo lag. Has anybody idea how many whirls...

hi all 2006 335i has recently started a rattle from what I've now been told is the turbocharger wastegate. Does anyone know if this is easily repairable? It seems to be a known issue which has been accepted as a fault by BMW in the US but I havent heard anything about it in the UK. I love...

Last year the car developed a problem: it was down on power and sruggled to cruise at even low speeds, now needing more gas - I had a new turbo installed (recon) as it needed one but the problem persisted. Eventually it was tracked down to the pipe coming off the actuator: it had collapsed. The...
