BMW 2009 325SE Auto

My partner has had this BMW from new, over the past 5 years he has done very few miles (dec 23 to dec 24 269 miles). It’s not given us any trouble over the years but 2 weeks ago he started it up and put it in reverse and it started to judder the yellow engine warning light came on and when he switched it off there was a smell of petrol. We called the AA out the following week they put on there diagnostics tool and said it recorded/faults 3 misfires, but it did not make sense as the first one was only 250 miles after he brought it and the rest did not correspond to the mileage. (Sorry I am not a car person so the terminology may well be wrong) he said the petrol smell was unburnt fuel. Anyway he reset the fault codes switched it on and it ran fine no problems told us to take it for a run we did for about an hour no problems. Tried to go out in it the next day it started juddering again warning light and smell of petrol. My partner is thinking of scrapping it or selling it for parts as he does not want an expensive repair on a car so old, but I am not so sure. It’s only done 41,000, no major problems in the past, tyre sensors replaced a few years back a new battery fitted in Nov 23. 
last service was 2 years ago by a garage (not dealership). Can anyone help, not sure what to do really apart from that in really good condition.

Welcome to the Forum

2 years since the last service ??? Just because Dealers advertise 30k between services doesn't mean it is good for the car? it is good for the sales campaign (reduced cost for the customer) and while new means the car will take it. All sorts of things can start to fail with age (I know I am old) Spark Plugs I would take a bet that the ones in the car are original. Coil Packs can fail and degrade the ones on the car are probably 15 years old now. 

Google the Register of BMW Specialists there will be one near to you get them to carry out a FULL service and diagnostic scan. Yes it will cost a few ££ but will be a lot cheaper than the cost and agravation of changing the car.
