E92 330i fuel issue N53

[mike9009]

Hi

I couldn't find anything on the net on this issue.

Last two fill-ups, my car has smelt of petrol. The smell clears after a couple of gallons. It smells inside and out. During this time the car occasionally splutters and has stalled. However once the smell has gone, the rough running also disappears. No warning lights come on.

Any likely culprits? Is the rough running coincidental?

Thanks

Just to close this item.

Took my 330i Coupe into BMW for an MOT yesterday. When I dropped it off, noticed a recall was due. (My car had not been to BMW since about 2011, but serviced every year at a specialist)

The recall was new injectors and new coils. The injectors have now been replaced (coils in a couple of weeks) but this 'seems' to have solved the issues.

And passed the MOT with one advisory (front tyre)

Hi Mike,

I have a 330i/N53 in the E91 (2008 LCI) and haven't heard about this recall. I was aware of the injector/coil/HPFP issues with the N53 and that BMW was offering to replace these components when they had failed, but not on a precautionary basis, as your post would seem to suggest? What year is your E92 and how did the dealer raise the recall issue with you please?

Cheers

I was a little surprised too. Mine is a late 2007 (57 plate), but as stated mine has not been to BMW since 2010- 2011, so has probably missed any work/ recalls as it has been outside the network. Mine is low mileage (51k), but this should have no influence, surely?

The dealership had not looked at the car to diagnose injector/ coil issues, but when booking the MOT I did ask for an intermittent EML and some running issues when the fuel tank was full, to be looked at. The recall stamp was on the paperwork when I arrived to drop the car off for MOT.

The other odd thing is I am only the second owner - so getting in touch with the original owner 'should' have been quite simple for BMW??

When I drop the car off for the coils, I will probe a little further to see what VIN numbers/ criteria are used for my 'recall'.

I will try to ask about what injectors were fitted too. (Sorry cannot be bothered taking my daily apart for this - I have too much on-going work to do on my T25......)

Me bad, sorry to mislead everyone but the injectors were not replaced after all, there was simply an item to check the injectors in the recall notice. There were no reported issues with them. Not sure if they would be replaced FOC if there was an issue?? The service desk personnel do not seem that knowledgeable.....

I have had the ignition coils replaced under recall though.

Whilst in, BMW completed some diagnostics, and the NOx sensor is throwing some errors. They quoted £480 to replace.

So, my question is, will the ignition coil replacement potentially solve the NOx errors being thrown up? I will wait and see if my EML comes on again or not before committing to replacing the NOx sensor. The EML only comes on when cold on a morning, about once a fortnight. Stopping and restarting clears the EML.
