Any suggestions about remapping my TD6 (2005) Its not got much torque oomph below 2500 rpm
I'm in Kent, and would travel to the midlands ish. (and a GAP tool if it can be home done)
I know about the gearbox problems, but its only done 85,000 miles and the gearbox feels under load when stationary, so I guess its fairly healthy (unless someone says that's a bad sign!!)

Just would be nice to get a bit more lower end grunt.

As always I try to do stuff on a shoestring budget and have got some way to do a custom DIY ECU remap. I just don't have the guts yet to press the "write" button as I need my car for work every day at the moment. Anyway, you need a laptop running Windows XP. A cheap eBay interface with Galletto software. You read the ECU file from your car by selecting BMW E53 X5, then the Siemens ECU. If it connects ok you can then copy the original ECU map file. Once you have the file send it off to a specialist mapper and tell them what you want regarding economy and performance.
The guy who did my remap advised to make sure the car battery is 100% ok and better still have it connected to a charger whilst the write is going on. He warned it could take 20mins or more on some cars. Nothing can interrupt the writing process or you will brick your ecu.
I have the remapped file if you are interested PM Me, it's a modest economy/performance update as I don't want to test the chocolate gearbox torque limits.
I would be very interested to hear of anyone using Galletto to remap a TD6, how did it go?
The guy who did the remap of my file said all is not lost if you brick the ECU, if removed and sent to him he could do the write on a bench and restore the ECU. 2007 TDV8 VSE
2003 TD6 gone.
2002 P38a gone
1999 P38a gone
1997 p38a gone
1993 VSE gone
1992 VSE gone
1966 Series 2a with V8 conversion gone

Check your Turbo Actuator isn't stuck, or not moving for another reason, Mine was missing a bit of vacuum hose and was a slow as hell. Replaced and off she goes.

If you want a remap try Gareth at Empire in Essex, he knows his stuff.

Haven't remapped yet but have done the EGR blank. Made a very noticeable improvement in both pick up/acelleration and economy

Any idea on how to check the turbo, it seems buried and then they built the rest of the car about it!!!!!

I managed to get to the actuator from below, with a pair of grips. And Che k it moved. Then traced the hoses up, and found one missing, replaced and was working again.
