    Hi guys, I own a E87 (118i) manufactured in 2009 with a N43 engine (4 cylinders) which is having a hard time. When cracking, it dies after 1 to 3 seconds if no gas applied. When gas is applied I'm able to keep the engine running but very unstable. I've done some diagnostics and tests and...

  12. BMW 1 Series - Tech Talk For All Gen Of 1 Series
    Looking to buy my first BMW - a 1.6L is all I can afford to run petrol and insurance wise. I've been drawn to the 2008 3dr 116i SE because of its looks, features and the sporty nature of a 3dr. I'm looking for a fun car for a year, nothing longterm. No need for a 5 door unless buying a 3dr is a...

    Low Oil Pressure Light- Doesn’t always happen but when it does it comes on after driving around 10 miles, not the timing chain or pickup pipe as BMW already checked that and replaced the strainer and pickup pipe. Light goes away after turning off but usually comes back on not long after.
