Cool, just advising, not advocating non-supermarket or premium fuel, whateverFox889 wrote:I wasn't advocating the OP using 'Premium' fuel just advising, perhaps, he used 'non supermarket' based fuel just to see if it made any difference.Ewazix wrote:There are 35 million cars in the UK and most are run on 95 RON without any problem. The M54 N52 engine is rated by BMW to run on 95 RON and despite what we would like to think there is nothing THAT special about the engine. I use premium because I'd like to think it's 'better' but using 95 ron isn't going to shut your car down and junk you in the fast lane!Fox889 wrote:
Not wishing to upset anyone or face libel action, the first thing I would do is 'not use supermarket fuel'!
Secondly, and for no other reason apart from being 'anal' I would rather use the super-duper stuff than ordinary fuel.
It may make a difference you never know!
The OP has another problem and needs to check for fault codes as a starter, anything else is guesswork.
Either way fuel brand or RON isn't going to cure the problem described by the OP. Hopefully the code reader will give a starting point
after dropping my daughter home tonight I gave the car a bit of gas in 4th down the dual and same again. EML and engine light on and limp mode. Pulled over and the car was reving eraticly between 1500-3000 rpm, turned ignition off and then back on all ok. Got home and plugged OBD back in and this is what it picked up......any ideas? ?
