I wish I was like everyone else on the forum, talking about the new 135i that I'm buying. Instead, My 118i gave up on me on the way home from work.

Took off from a traffic light and got a bit of a jerk, the power dropped and the consumption increased exponentially. Lucky I was 2km from home and was able to drive it back.
Its idling like a car with an after market cam and I can smell fuel. Absolutely no power, just driveable (enough to get me to a mechanic).

No lights have popped up on my dash.

Anyone have any idea what could be wrong?? Spark plugs? Coil pack?
The plugs were last changed 23 000km ago. The recommended mileage is 50 000km. (Still, I'm hoping its just the plugs misfiring.) :bangdesk::argh::bangdesk::argh:

:dunno:

But hope you can sort it out quickly and cheaply:thumbs:

Sorry to hear bud :sorry:

I'm no expert (far from it, actually), but what about the fuel pump?

 

[DangerD]

Double post. Mods, please delete the last thread. Shot.

@petri. I hope so too man. I just sold the car. Meant to take it in next Monday!!!:argh:

I doubt its the fuel pump. It's idling quite heavy. The engine is all over the place on the idle.

I opened the bonnet and thought to myself "!@#$, this is not a golf 1."

Howzit bud, a few things you should, Maf sensor, Vanos or oil pump any one of them will give you the above symptoms, my gut says the vanos. drain out a bit of oil from the engine. take about 500ml diesel and pour in to the engine, let the engine run for a bit and rev it a few times. switch off let the oil drain over night so everything gets out, replace the oil filter and new oil and see if its fine. should clean out most of the crap in the engine. if it works do this every 5000kms for about 3 times this will ensure that your engine is free of all the crap that caused the issue :thumbs:

+1 Try this first :thumbs:

It's probably a coil pack that has failed. Best to get diagnostics done to see which cylinder is misfiring.

A safer way to clean the "gum" inside of an engine is to add one 500ml bottle of ATF and drive like that for 1000km at normal rpm, no red lining the engine. Drain oil and replace filter and oil.

My gut still says coil pack or maybe even plug.

And the winner is.... SP33DYV! :bravo:

Took it to Autoway in Fourways (on recommendation of a friend).
Dropped it off at 8am, quoted at 10am, picked up the car at 1pm.

It was two of the coil packs. The mech recommended that I change all four but after I told him that I'm trading it in on Monday he said it's fine to replace just those two.

If anyone is curious, packs came to R500ea (excl VAT)

Glad it all worked out.

Nice one :rollsmile:

Also replaced my coil pack month ago. The mech says when one starts giving trouble wont be long before the rest also that why BMW recommend you replace all at once.
