E90 335i fault

MrRigma · 12-16-2017, 11:49 AM

Hi Chaps

Can anyone help me diagnose my 09 335i? 39k miles not driven it for a week or two due to snow etc. Took it out today and it started to fire on 3 cylinders or something ran really rough. Recovered a bit then when i press on it all goes to pot again. No issues starting etc just down on power misfiring and sounds like a 2cv when the engine light comes on. Figured it would be electric perhaps or maybe HPFP? Can't seem to find any details in the computer via the hidden menus so I guess it needs an OBD...

Sounds like injectors or HPFP symptoms, you really need to plug in diagnostics to see what's going on first.

Yeah exactly. I've got a mondial warranty on it, might just chuck it at the stealers!

If you've got warranty I wouldnt have even bothered starting the thread.😂
Chuck it at BMW and they will sort it under the warranty.

£250 excess

Think it's a coil pack P0306

That'll be cheaper than your excess so no brainer really.

Got a new coil pack. Fitted it cleared codes and it's running sweet as a nut again :-)
