2008 328i issues

ramm_e90 · 02-16-2016, 09:34 AM

Just this last week my 328i began to give me a check engine light about a half hour after I began driving. It would happen randomly and the light would go away after I turned the car off. I would accelerate and between 2k and 3k rpm, the transmission would begin to feel heavy and it would downshift randomly and the car would begin to shake. I would stop on the side of the road and turn the car off and everything would reset and it would no longer shake. I am beyond confused and need some help before I go to my BMW dealer.
thanks

If you can scan it do it but at first guess you could be looking at a faulty Valvetronic Eccentric Shaft Sensor, Vanos solenoids or ignition coil(s).

But plz scan your car and post your codes as the possibilities are endless and we are not magicians.

coils?

There's bound to be a stored fault. If it's a misfire on a specific cylinder, then move the coil from that cylinder to another cylinder and see if the fault follows it.

My n52 shakes pretty aggressively at idle and after WOT it would throw check engine and shake terribly u Gil restart car than would go away. Changed plugs & all 6 coils and was good to go. Good luck op and let us know what the dealer says or the codes.

Yeah, I'm thinking coils too since it is not too persistent and the problem disappears after turning the car on and off.

Thank god someone has the same issue. I'm going to do some more research on the coils and plugs and then have the dealer take a look at it before I do anything.

Okay I will give that a try. Thanks

I had the same issue. Replaced all plugs/coils and it was back to normal. Good luck.

ny325 · 02-18-2016, 10:46 PM

Had the same issue this morning. Bringing it in tm my Indy. Most likely a engine coil.

STRMTRPR · 03-03-2016, 07:23 AM

Sounds like it could be Coils.

ramm_e90 · 03-03-2016, 07:26 AM

A $45 OBD2 code reader would have saved you a lot of headache and not wasted a bunch of time.

For about 100 you get Carly for bmw app and their dongle. Shadow codes, parimiters, coding

Also, the dongle works with other apps (torque, obd fusion, etc) so you can use in other vehicles as well.

There are lots of sources for code readers. I was pointing out that when the car has a SES light, the easiest and most convenient device is a simple OBD2 code reader which can be kept in the glove box. If the OP isn't into coding or actually diagnosing and DIY, an OBD2 code reader is an inexpensive device to use on any car.

I agree with above comments on getting the codes read, then you know what you are up against. Also, just had a similar issue on a 2009 328i that showed a misfire so my first step was to swap coils to see if the problem moved... luckily I checked the plugs when I did this and they were fouled and gap wasn't correct so I replaced them and no problems since. If your swapping coils take a peak at your plug, only takes an extra minute or two
