Strange long cranking on a 328d

BimmerMat135 · 12-21-2017, 05:45 PM

I had a hard time starting the car which was warm at the time. It did crank for 5-7 seconds before starting. It felt strange as it is the first time I ever experienced anything like that. I stop it after while and it restart right up like nothing happen. The only thing I could see is that maybe I wasn't pressing hard enough on the brake pedal. Anybody ever had this problem?

Pressing on the brake pedal is required so that the car doesn't start and immediately take off. If you weren't pressing hard enough on the pedal the engine wouldn't turn over at all.

so this hasn't happened to my f30 but it did happen to my e90. It happened a few times within a few months and then eventually the starter died.

Well I guess it all part of bmw legendary reliability. The warranty is ending in March so it's a good time for the starter to fail after that.

I had the "long-cranking" symptom in my 2007 E92 335i, and it turned out to be the infamous high-pressure fuel pump problem which was immediately fixed by the dealership at no cost. Aside from that, I've not had any reliability issues with any of the BMWs I've owned. Since yours is a diesel, it could be a fuel pump problem, the starter, or a temperature-related problem. I don't know if the newer diesels have glow-plugs to warm the combustion chambers for cold-starts, but it certainly could be related to the starter not turning the engine over fast enough.

Well, there you go...wasn't aware of that, but it sounds plausible. The gas-engine cars have something similar that starts the LPFP so it will prime the HPFP when you unlock or open a door to prevent the same type problem with long-cranking.

Why are you thinking the starter is failing?

I'm reading it is cranking... typical speed or slow?

Likely fuel pressure, (low or high pressure) if it is not attempting to start while cranking.

I saw few videos of this It actually look similar to the hpfp video. It is something I'm looking after in my 1M since it also have the N54 engine

It could be this but the car was warm at the time so probably it wouldn't need the glow plug to start.

Well as far as I know and as far as I could hear the starter seem perfectly fine. I was thinking out loud following a previous reply. I wonder if diesel models got the same fuel system including the hpfp and lpfp as well? I will have to find parts # in order to know if they are the same as gasoline car.

Something else that came to my mind could be the transmission engagement I remember looking at the rev around 300rpm while the car was cranking. Also there was much more vibration than usual. Is it possible that somehow the torque converter was partly engaged even with the car in park?

You need it on diagnostics, to see what codes it is showing, if any.

Both low and high pressure must be OK to get a start. Doesn't necessarily mean pumps are the cause, could be a sensor at fault.
