Question is the technician said he can hear a ticking noise coming he thinks from the HPFP and said it could be the bearing that actuates the pump ? they have done a lot of B58 tunes and did say mine sounded different albeit slightly due to this noise he can hear.
I myself can't hear anything but that means nothing lol
Did an oil and filter change and NGK spark plug change 1 week prior the tune to make sure it was at it's best.
Car is 2016 stock 340i except from full cat back remus exhaust system.
Had the noisy cold start removed and the sport display update to show new power levels, running extremely well and my butt dyno can sure feel the extra grunt.
Is it worth me removing the HPFP and pulling the follower to pump drive out for inspection ?
29000 miles and ZERO issues so far.
Anyone want to see the dyno print out i will sort it.
Older dude but still love my cars  |
if you could post a recording that'd be great
