stobbie Posted August 28, 2017 Share Posted August 28, 2017 Has anyone on here converted a tdci to 300tdi? We have one of our rental defenders with a broken engine and are fed up with all the TDCI problems. Our 300 TDI's don't give any problems at all.

western Posted August 28, 2017 Share Posted August 28, 2017 Check if your vehicle licencing/testing dept will allow a non Euro 5 or 6 engine to be replaced with a older engine, Quote Link to comment Share on other sites More sharing options...
stobbie Posted August 28, 2017 Author Share Posted August 28, 2017 No, it isn't allowed, but it will never be tested again. We only have tot have an engine conversion tested if the number of cilinders or type of fuel changes.. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted August 28, 2017 Share Posted August 28, 2017 In theory I'm sure it would be possible and I would be interested in how you get on should you try it. Some issues you may come across though: Packaging in engine bay - fairly simple to sort as most of the add-on stuff would go with the Tdci. Instrument pack uses CANBUS - people have adapted round this either with some computer trickery or by mounting older gauges into the newer dash instead. Wrong gearbox - I think an adaptor is available to use the MT82 or you could put an R380 in. Gearsticks clash with dash (if using R380) - IIRC this can be avoided by altering them. General electronics - probably best to strip the Tdci loom down to suit the Tdi. I would suggest however that it may be simpler to just fix the issues with the current engine. Or replace the vehicle.

Arjan Posted August 28, 2017 Share Posted August 28, 2017 Technically possible, but there are few buts in this : - Money. Getting a replacement engine is less money than converting the vehicle - Resale value with original engine likely to be better - Legality. Just because the # of cylinders aren't counted when going for the APK (Dutch MOT) means the change is legal. It could be a cause for the insure to void your cover if you don't tell them. Apart from a few other minor problems.. The Tdci's aren't that bad. Perhaps the drivers needs to training.. Succes ! Quote Link to comment Share on other sites More sharing options...
Happyoldgit Posted August 28, 2017 Share Posted August 28, 2017 Agreed, TDCI's aren't that bad at all - I've had a few. Far far easier to replace like for like then sell the vehicle. Quote Link to comment Share on other sites More sharing options...
stobbie Posted August 29, 2017 Author Share Posted August 29, 2017 We have replaced several low mileage tdci engines for customers this year and have replaced several turbo's, injectors, vcv valves etc. On this rental car we have replaced a turbo already this year and now it has several other problems. It is still running however. Everything is way more expensive on a tdci than on a 300tdi and breaks more often. I almost never have to replace a 300 turbo even at very very high mileages, injectors keep going for ever, no problems with bearings etc. Only a head gasket every other 250.000km, but that's a 3 hour job on a tdi. If I would fit a 300tdi I would use an MT82 adapter and I would retain all wiring and even the engine ecu, without the engine. Then I would just have to fit a tdci temp sender to the 300tdi and everything should work exempt for the rpm signal, but I don't need that. It would be way cheaper than a replacement engine because I have several good 300tdi's lying around. I would just have to buy the mt82 adapter. But I'm not going to do it.... Because it's a rental car it will have to be legal... Quote Link to comment Share on other sites More sharing options...
Arjan Posted August 29, 2017 Share Posted August 29, 2017 Think it is in your own words..... Rental Car... Keep it simple, keep it legal. See if you can swop it, once running again, against a 300 Tdi ? Quote Link to comment Share on other sites More sharing options...
stobbie Posted August 29, 2017 Author Share Posted August 29, 2017 Yes, that would be a possibility.. .. Quote Link to comment Share on other sites More sharing options...
