335i coils damaged...

[Moe]

just checked with a friend of mine who own another 335i..and he got his coils changed at 18,000 km... !! so i think its a common issue

[RAFiK]

I changed my coils at 135,000 km .... I mean coils should last you at least a 100,000 km !

Good luck Moe, that really sucks ! keep us updated !

The only explaining I can offer, although based on 2 cars only can't qualify the issue as a recall, but....

Since this platform (N54 engine) is BMWs first mass-produced FI car, maybe they've used coils that are near to NA engines specs, therefore not handling the timing requirements associated with turbo cars (more, faster ignition is required per unit of time). Checking part numbers also shows that E92 335i cars up to December 2006 were equipped with coils (part # 12137551049) that got discontinued. What's your production date? Beyond that date, the 335i (N54) and the 330i (N52N) shared the same coils (part # 12137571643). That could be the problem.

hmmm .... :goodpost: !

We were discussing the same issue that it could be that the Coils are not handling the power the car is exerting on them ! ..

Dude my drivin has nothin to do with a coil failure but i would go with ur 1st suggestion i think this car is just Cursed !!!

i was joking around:lol: idioto!

Ur right Black Betty as i installed mine for the amount of 1740dhs along with the rubber sockets that will also set u back for 405dhs...... and ofcourse a set of fresh sparkplugs that cost 300dhs

so it addes up to 2445dhs :bricks:

Man i was really pissed

Thankfully your spark plugs are not as expensive as ours "e46" 110 each.


I did my home work and bought a set of coils for my e46 M3 2 months ago and kept them in the garage just in case.

Moe, cross reference those part numbers with your friend who replaced his coils. If he's got the new part numbers, then mistery solved .

wow sorry to hear that bro, i wonder if mine is damaged already..

[Moe]

Ppl i really can't blv wuts happening , just called the guy and he was like ur coils are ok but ur issue is in the fuel tank.. !!!! -_- wut kinda agent is Agmc !!

[Ayham]

What in your fuel tank needs replacing? Pump?

[Moe]

"a hose " its not deliverin enough fuel to the engine...!

[Ayham]

It's either leaking, or clogged! And it can't get clogged naturally, unless your fuel filter is, which is impossible at your mileage and our fuel standards!

[Moe]

maybe its leaking.. !!!

[SewerSideUp]

If it was leaking enough to not feed the fuel rail properly. then you'd atleast see or smell some fuel somewhere in and/or around the car .

Probably fuel pump pressure, it usually causes that.

Any updates though ? This thread's been dead for some time now ...

[Moe]

got my car a couple of weeks bak and its fine .. :D

[odarwish]

Bro i have a 2008 335 and i had the engine fault warning when my car had 3k on it...but when i was driving you could feel that there is something wrong. and when i fixed it they said it was something with the fuel/air mixture computer its not delivering the proper mixture its delivering alot of fuel no air.

so they changed that and i have never had it again
