I have recently bought a 2003 BMW E60 530D Automatic with 130k miles. Drives lovely. Only issue is when I'm driving say 50mph on dual carriageway and want to accelerate hard, it kicks down fine and the engine revs, but no real power. All of a sudden I'll get about 2 seconds of boost/power...

Hey guys. So I got E61 530D, and like a month ago started to notice that sometimes it haven’t got power when I start driving from traffic lights, and wont go past like 2.1k RPM. And i can hold it as long as I want , and its barely moving (and if i hold it for very long engine starts to kinda...

I am experiencing no torque under 2500 rpm, almost feels like a turbo lag. And car spews black smoke but not instantly after pressing the pedal. I have changed the air filter, changed MAP, and an injector The previous MAP read 1300kpa at idle and without turning the car on, now it reads...

I'm trying to fit a sprint boost controller to my new e93 335i. I successfully installed and took it off my 325i, but cannot get it on my 335i The problem I am having is that once I have undone the bolt holding the accelerator down, I can't then remove the existing plug from the accelerator. It...

I took my 335d to the remapper today and on the dyno he said my small turbo isn't boosting, it only boosts when it hits around 3000 revs, I've been reading a few posts and they say it could be a turno preassure solenoid valve is this correct ?

Hello guy, I own a E46 320d 2005 EU4 BMW and I'm starting to face a problem with a turbo. When it's cold the car works fine, but the hotter outside, the more my turbo gets lost. Sometimes it starts pulsating, sometimes it stops working and when that happens changing a gear sometimes brings it...

2004 E46 330Cd Boost Problems - FIXED! Hey all, So I've not driven the car much the last few months because of a lower back problem I have, but it seems to have now developed a bit of a problem with the turbo not boosting properly. It's completely random. Sometimes it will boost fine...

I'm a total noob when it comes to BNWs, I'm no mechanic either, so please bear with me. I bought a 2016 535d a week ago, low milage 29k, in nice condition. I've noticed over the week that the throttle response seems to vary a lot. Occasionally at around 40/50mph the lightest press of the...

I decided to write a quick guide on how to install a boost gauge in a 1 series (e87, e82 etc) because no one else on any forum I could find has. Its also the same procedure for hardwiring a dash cam which I did at the same time but the wire routing is different. Q: Why would you install a boost...

Hey peeps, So I was doing my spring inspection on my e46 320d and I found that I've got what seems to be a slow oil leak from the boost pipe. It seems to be dripping from right under where the rubber pipe connects to the metal elbow just before the EGR valve. Its drips very slowly on to the...

Hi All, I have a rather frustrating issue that has reared its head. When on a journey I find the car goes into limp home mode, no engine warning light, oil light or smoke. Just extremely slow. There is no boost from the turbo at all. On the same journey it can come back to life again. The car...
