I just went through this and if it shows 5088 or 5088 L1-L4 (Foxwell NT-510) the 5088 is the magnetic reed switch in the valve body.

If it shows the 5088 L1-L4 then it's the mechatronic gearshift.

The interlock cable can also be screwed up and may show as either.

The L1-L4 is show in the extension description on the Foxwell but I have no idea if it or how it shows with other scanners.
