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...

Can't get my head around this one, my 03 E60 suddenly has no boost. It drives fine, no noises and smooth as it's every been. Scanned the car and came up with these faults. P1253 Boost Pressure Position Circuit Open P1252 Charge air pressure actuator short to ground Thing is that this car has...

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...

hello all, just been and replaced the turbo > intercooler pipe and hose last week as had a huge boost leak from it (clamp attaching to turbo was snapped and the lower connection to intercooler failed on one side.) and since i have changed them and checked INPA boost data i have noticed that the...

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 recently changed my o2 sensor which I got from the breakers yard because i had the one fault oxygen sensor heater activation fault, but since changing the sensor unfortunately all the below errors have now came up - just to add I get the orange emissions light come up when I start...

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...

Hello everyone, I'm new on the forum. My car's problem has forced me to register on every single BMW forum out there. So back to the point. I have a 2003 320d m47n 110kw. last May I had to replace the engine and the turbo(they died). Engine is the same with 110k miles on it. Since then my car...

Hi all, Just to clarify before i start, i have used the search function and have found some very helpful threads, however, i didn't really find any thread with both EML codes. I have a 2005 E46 320d Touring, every since i have had it the EML has been on, only code its really had up until...

Anybody know the location of the boost pressure sensor on a 2008 330d cheers

I was just after some advice.. My car was smoking quite bad on full boost and power was down, I felt like i could hear a hissing or boost leak and knowing I hadn't changed the dreaded intercooler hose, I started to investigate there. I found the old oem pipe to have a split, so I ordered a new...
