BMW 325i 2010 3.0 rough drive and ticking noise

[KPS 0]

Hi guys,

Bought BMW 325i 3.0 in December 2016. Absolutely no issues when I drove it from Auckland to Wellington. After few days I noticed these issues in the BMW

* annoying noise in the cabin when I drive the BMW

* noise goes away when switch to N, in the middle of the driving (that what BMW guys said, they said could be transmission thing, but needs a transmission to hear the noise)

* it runs very rough, not quiet, sounds like Diesel

* ticking noise from the engine

* Steering shakes when idle

* Poor acceleration

* Vibration through the pedals

* Slow shifting of gears

* drives uphill, engines misfires sometimes (Engine light came once)

 

It used to drive very smooth, super quiet and powerful.

I went to one of the European cars specialist in Wellington, they carried out diagnostic scan and no codes found in system, carried out live data test all OK,

they suspect fault with cam followers and rockers rollers.

 

Gave me a hefty quote to fix it, they said all rollers and lifters will need to be replaced, quoted me around $6000

Any suggestions, help would be appreciated.

Any one had similar kind of issues with E90 325i?

what year? and how much did you pay for the car.

Is there no warranty? or was it private sale

you could prob replace the whole motor for that with a wrecked one.

Maybe try dropping the oil, and run a strong magnet through it to see if there's any metal shavings?  You can get those neodymium magnets for doors from Mitre 10 for like $10. 

If you hadn't have gotten it checked over by a Euro Specialist I would have been looking more towards either Vanos, a coil pack, crank or cam sensors.
