Hello all, So I am aware of the horror stories and problems with the various F10/11 powe units such as the N47, rarely the N57, N20, N53, etc. I am wondering if you have any feedback as to how the B47 which is the current, modular 2.0 diesel engine introduced into the 5 series before any...

Hi, first post unfortunately looking for help..... My low pressure fuel sensor failed and passed fuel through the loom to the ECU and this has failed. You could head fuel sloshing about inside the case... I’ve had it tested and the report back is that it’s unreadable even for cloning. Does...

My son is looking to buy a 10 plate (May 2010) 120d M Sport Coupe. Is it the N47 engine on this car and if so is it as troublesome as some say? Car has service history and 62k

I need to replace the valve cover gasket on my 2007 3.0 Si N52 engine done 60,000 miles. We have had this car for 3 years now and I have only had to change the starter motor and clean the vanos solenoids. So although I am comfortable working on the engine, I need to get all the advise that I...

Hi, hope someone here can help. Drove home from work yesterday evening, everything was fine. Nipped out to shops about 90 mins later and my engine has started making a hell of a noise (see clip), along with a short 1-2 second hiss when it's turned back off. https://vimeo.com/362757191 Initial...

I know there's separate forum for intros but I'll start by saying I own a 2006 (E87) 120D, it has the M47 engine and has over 103k miles. It is my first car and I am keen to learn how to maintain it myself and do small jobs myself, namely servicing. I've just done a service, with help from a...

Hi Folks, Strange thing happened tonight. Came out to find a dead battery on my E90 (320D, 2005 model) I got a jump from the neighbor, car started up more or less fine. Drove to work and the entire drive in i seemed to be missing what feels like around 60hp from the engine. It feels like the...

Hi- 320d N47 is haemorrhaging diesel from under the engine bay when engine running. First noticed a bit of a whistle when turning engine off after it had ran for a while. Then I noticed loads of diesel pouring out from underneath the engine. Any ideas if the two are likely to be related??

Good evening all! Currently having a problem with my BMW 320i. As hopefully you can see in the attached images my revs are at a constant 650rpm until it drops (nearly hitting 500rpm) every so often, somtimes 3 or 4 times in a row. Sometimes its perfectly steady, and yet others, it feels like it...

I fancy a 4wd f30 as my next motor, however I'm not too sure on the best engine option. Currently I have an e90 330d manual with a remap which makes a great daily driver. It's the only derv I've ever owned as I've never been the greatest fan of them. Ideally I'd like a petrol with a manual...
