Laurie,BMW 320D Touring
My 2004 BMW 320d with over 70000 miles on the clock recently gave me over 700 miles from a single tankful of fuel. And I wasn't driving slowly!
Just wanted to update you with progress. No problems fitting the unit now - quite clear where the little tinker is supposed to reside. Plug fitted in-circuit in about 10 mins then a bit of head scratching on where to position the unit itself. In the end I went for what looks like a redundant plastic bracket at the front of the air filter assembly on nearside (I'm thinking plastic might reduce vibration somewhat) and the cable routes alongside other cables on top of the rad. This also makes it easy to uninstall for service time (I'm a bit paranoid about Volvo dealer whingeing about warranty etc. so I'll take the short time to remove and refit as it's so straightforward). Couldn't resist tweaking the dial from 5 to 6 but won't go beyond that - no need in retrospect. Results: Amazing! Very, very impressed that such a straightforward addition can provide substantive and noticeable all round improvements - without any apparent compromises (are there any?) - specifically: - Engine is much smoother, particularly at idle up to about 1600 rpm which is normal 'about town' traffic; is also smoother at motorway speeds - Noticeable improvement in power/torque at mid- high-range rpm and certainly faster pick up from low revs - there was a considerable 'lag' before that has reduced considerably. It's a different drive. - After just one weekend and about 250 miles of mixed motoring the mpg meter is returning an improvement of +2mpg to normal (now just over 48mpg) - I've not got over this before and I'm certain with some longer runs this is going to be much improved - I'll let you know in a month's time how it's going. End result - very happy for now. What I don't understand is how or why Volvo with all their R&D capability can't deliver this on the car itself? Or is this just 2 years of technology development? Thanks a
