Hello everyone. First post here. I also have a 2013 EB. I have seen a lot of post of ticking from the engine compartment and the general opinion is that it is the direct injection. This is the first thread I have found even close to my problem. I have a noise coming from the passenger side floor board a cruising speed. It is very faint and the dealer says it is air coming through my vents. Dealer BS. Like I said it is very faint so under hard acceleration I don't hear it. It almost sounds like a break pad rubbing or a old mechanical tach cable. A very metallic sound. I can't think it is anything bad as the truck is driving and running great. Its just one of those things that every now and then I turn the radio down to see inf it is still there. The truck is 4wd and has 1500 miles on it. I started noticing it around 700. I have since tried switching to a higher octain fuel but no change. I have now done a leveling kit and tires and wheels and no change. My front end shop gave everything a good looking over and found nothing. Any ideas?
