Kaliboy Posted October 26, 2016 Share Posted October 26, 2016 Try getting a remap. TD5s react well to them and they make a substantial difference. As your's is an early model, it might need a chip soldering rather than just a software remap. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted October 26, 2016 Share Posted October 26, 2016 Before any remap, ensure the truck is running properly first! Have you had any diagnostics done? Quote Link to comment Share on other sites More sharing options...
bear Posted October 26, 2016 Share Posted October 26, 2016 Hi, My turbo doesn't seem to kick in till the same as your. I think it's normal as mine's not been re-mapped and is a manual. Griff Quote Link to comment Share on other sites More sharing options...
talby2491 Posted October 26, 2016 Author Share Posted October 26, 2016 thanks all for information I have had the discovery on a diagnostic machine and there are no fault codes showing Quote Link to comment Share on other sites More sharing options...
Rickspark Posted October 27, 2016 Share Posted October 27, 2016 I agree Bear. Had my TD5 for 13 years. Reckon mine starts to really work at just over 2200 rpm. Isn't this just a characteristic of the vehicle? I.e. The engine need to be doing work to make the turbo spin to blow air into the engine?

honitonhobbit Posted October 27, 2016 Share Posted October 27, 2016 What Bowie said, get it checked on a diagnostic first - remapping a malfunctioning engine is like fitting a boost pin; pointless An 'X' reg TD5 is old; it's been owned by a fair few folk, who have progressively spent less and less on maintenance until you bought it. so get it back to spec. Also, it's worth noting that the TD5 auto in standard form is a bit of a slug. I'd suggest a de cat as well as what you have done. Also check the fuel pump and fuel regulator are functioning properly Then when it's functioning A Ok, take it to IRB and get it tweaked Quote Link to comment Share on other sites More sharing options...
spiker3 Posted October 29, 2016 Share Posted October 29, 2016 Hi guys, I have a 2001 td5 manual, It maybe the way I drive but mine seems to kick in around 1500 to 2000 rpm, way before yours. Is that normal or is it me? Quote Link to comment Share on other sites More sharing options...
Tal Posted October 29, 2016 Share Posted October 29, 2016 2000 ish on mine as well. I stall it if I forget and think I'm driving the 200 or 300tdi which both start to power up at lower revs. Quote Link to comment Share on other sites More sharing options...
spiker3 Posted October 30, 2016 Share Posted October 30, 2016 Yeah, You really have to change up and down the gears to make sure the revs don't drop too much. I probably should have got an auto. Quote Link to comment Share on other sites More sharing options...
