Defender_300Tdi Posted November 9, 2008 Share Posted November 9, 2008 Hi All I normally wouldn’t enter the disco forum (defender all the way)...but here goes! My mate has offered me a Td5 engine disco that has a blown engine....assuming I could get a replacement engine of eblag or something how easy are TD5's to swop? I mean I have done defender 200 and 300 swaps before but have always been scared by TD5 electrics...is it really a case of plug in and play?! Reckon it could be done in a weekend? I have all the tools but am worried about ECU's badgering me around and lots of dash lights flashing at me when and if I get to start the replacement engine after fitting it..... Any help would be great! Thanks Rob Quote Link to comment Share on other sites More sharing options...
bobtail4x4 Posted November 9, 2008 Share Posted November 9, 2008 I think before it will start the new engine need plugging in to a computer. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 9, 2008 Share Posted November 9, 2008 Ideally you want the right age engine for the age of vehicle i.e. 1999-2001 model year or 2002-2006 model year as they are slightly different. You will need a computer to put the injector grades from the new engine into the ECU, even if you change the engine ECU you will still need the computer because then you will need to resync the alarm code.

kevinr Posted November 9, 2008 Share Posted November 9, 2008 Sorry to hijack the thread, but just out of curiosity, do you need a testbook or something like that to get at the ECU, or does a laptop with the right software/cable work aswell..if so, where do I get the software?

sotal Posted November 9, 2008 Share Posted November 9, 2008 For the Td5's Nanocom will do most things - have a search for nanocom and it should answer most of your questions - approx £200+vat last time I looked Quote Link to comment Share on other sites More sharing options...
discojmz Posted November 9, 2008 Share Posted November 9, 2008 not knowing anything much about this, I have always wondered, supposing you managed to get an engine of the right year, and the injectors in the 'blown' engine are in good order, can you not swap the old injectors into the new engine (in the same positions) and plug it all together thus negating the need to do any computer jiggery pokery?

Yes you could do that but doing it the other way is not really a hard job, it takes about 5 min to reprogram injector grades with a Testbook, can't say I have tried it with a Nanocommie. Certainly a lot quicker than changing 2 sets of injectors over Quote Link to comment Share on other sites More sharing options...
Porny Posted November 10, 2008 Share Posted November 10, 2008 Rob, I've replied to your pm, but thought I'd post some of the answer here too for future reference.... A Td5 is no more difficult to swap than a 200 or 300Tdi. In all honesty you can use a Td5 from any age of Discovery or Defender... A Disco and Defender engine are the same bar a few ancilleries that can be easily swapped from the old engine. The ECU issue is an easy one.... If you put any age of Td5 engine in your Disco, it will run with the ECU that is currently fitted... but it won't be ideal. But it will run happily enough for you to do a test drive. If you use a pre 2002 engine.... Then your current ECU will be fine, but you will need to have the injector coding changed to match the injectors fitted to the 'new' engine. This takes about 5 mins once you have the rocker cover off to see what the injector codes are. If you use a post 2002 engine... Then you need a post 2002 ECU. This needs to be flashed with the correct files for a Discovery (if not already - Defender ECU is exactly the same), the throttle pedal will possibly need to be set to a two track (different throttle pedal on early and late Discoverys/Defenders), and you need to change the injector codes to match the 'new' engine. It will also need to be 'matched/learnt' to your Body Control Unit (immobilser function). This doesn't take very long (30 mins). Personnally... I'd go for the newest/low mileage engine I could find regardless of age. The only other thing you will need to change is the EGR set-up if you use a later engine - but I'd get rid of it anyway!! And to answer other questions... You could swap injectors over, but seems a lot more work that swapping a few codes!!! You can use later green top injectors in an early TD5, but I wouldn't put early injectors into a later Td5. Ian Quote Link to comment Share on other sites More sharing options...

If I do decide to buy this disco and get the engine fitted I may well me making the trip up north to have you have a look at the ECU....forum discount!?
