ok cut a long story short my 2003 bmw 318 e46 has not been started for 3 months i went to it today

done

fresh fuel

new oil and filter

turned engine over by hand

and had a genral visual check for anything wrong

i then connected the jump leads to it and begane to start the car it took alot of turning over coughing and spluttering sometimes only got a clicking noise as if battery was really flat other times it would turn over fine but we kept trying for about 20 mins and then eventually fired up but with a god almighty loud and i mean very loud tapping noise coming from the top end and a very intermitant like deep poping back noise coming from like bottom end but this was very rare and only poped like 3 times in 2 mins i had a mechanic friend look at it and he said its acting like the timing is out is also dont really want to stay running for very long unless you keep the jump leads on it

please please any ideas any one

Hmm interesting. It shouldn't be acting up like this

Was it okay before she was sat for 3 months?
