Seat travel I am 76" tall and I cannot get the power seat back far enough to be comfortable. My car is a 2001 525i. Is the range of seat travel adjustable?

That is likely built in and is not adjustable. Sorry.

Seat adjustment ranges are sometimes limited and sometimes there is a fault, such as a coin or something falling into one of the runners.

Cars intended for the premium market often have forward/back, up/down and sometimes tilt adjustment for the driver seat while for the small car, basic or budget market usually only have forward or back. Because on average a person who has shorter legs and needs the seat forward will also have a shorter body so enterprising designers have made the seat runners of some models slope upwards to lift the driver as the seat is moved forward.

Adjustable steering columns are fairly common, though only in the rise/fall plane. I haven't seen a telescopic column for many years. What is really needed is adjustable pedals but designers and manufacturers are very reluctant to go down that avenue, though there are companies specialising in such modifications.

You need to be on the ground on your knees with a good light looking under the seat to see if the available adjustment range takes the seat to the true limit of its travel in both directions.

Hello: Move seats all the way forward, raise seat up as far as it will go. Remove covers over seat tracks in rear(go through the back door on each side) remove 15mm nut or bolt on each track, pick up rear of seat far enough to release the front hooks pull seat back and lift seat out of car. Make sure you disconnect the power seat wiring after you get the seat positioned for removal. Prior to removing seat. Also disconnect the side air bag wiring (yellow) if equipped.

apart from a visit to a surgeon then i would suggest that unbolt the seat runners and re-drill the fixing holes a bit further back .This i have done on some different vehicles over the last 40 yrs for tall people and also i have done it for small people with big cars whose feet dont reach the pedals and bloted blocks of wood to the pedals as well ,then i have had to change the seat belt as well as after moving everything forewards the seat belt wouldnt stretch enough

you need to reset by obd for learn the start point

Your seat is bolted down. slide the seat all the way back as far as it will go, and look at the slide rails( tracks that the seat travels on), you will see 2 bolts. going into the floor on the rails. just undo the 2 bolts, and then slide the seat forward(slowly, the front has no bolts holding it), on the back side of the rails, are 2 more bolts. Remove thise bolts, and you should be able to remove the seat. (This is a manual seat, not a power seat) hope this helps, please rate helpful or not

First thing I'd do is go to any used car lot and sit in a similar vehicle. at 6'3" you are not excessively tall but that depends on how much of you is leg...sounds funny but people are not exactly the same. If that one is comfortable, check to make sure there is nothing caught in the track for your seat, and that it is going back as much as the one you tested.
If both vehicles are the same, you can remove the seat from the floor and re-locate the seat back a few inches. On many vehicles, at least two of the bolts may go directly into the top of the frame. You will need to tap new threads into those holes. I also recommend that you use a large (2"-3") washer on the bottom side of the others to prevent the bolt from pulling through in an accident. Track repairs if necessary on your seat are generally difficult and expensive unless you find something minor...in that case you can replace the entire seat with one from a scrapyard. If you don't have an unusual color, they are fairly easy to match.

i just pugt a 10" sub in my 89 k1500 regular cab right behind the drivers seat, sony, pioneer and alpine all make a box that doesnt affect how far back your seat will travel

Have you removed the seat from vehicle? I'd have to look at it, to go further.

If the seat track mechanism has play, it is possible that it is binding up because it reached the rearward limit of its travel, stalling the motor. You can try having someone <carefully> force the seat forward from behind as you engage the "forward" function of the switch. This may be enough to "unbind" the mechanism- if this is the issue.
Otherwise, it is likely that the forward function of the ower seat switch is no longer working. You could try to spray some electrical contact cleaner into the switch (being careful not to stain the seat upholstery), let it dry and then try the switch again, possibly wiggling it as you push it forward. If this works, it is likely a temporary fix and you should replace the switch to prevent it happening again.
