IS200D questions
Hi!
I have a IS200D and I would like to ask:
What problems were inherited from the IS220D engine to the IS200D engine?
Many people complained about the old IS220D engine has EGR, DPF problems.
Does the newer engine suffer from these?
What did lexus change on the newer engine?
What do I have to pay attention to to get a long engine life?
Best regards

ok... basically the engines are the same. one is the 2AD-FHV and the other i think is the 2AD-FTV. without double checking i think the FHV is the 220d and the FTV is the 200d. basically they de-tuned the earlier engine for lower emissions and subsequently less power. i looked into buying a 200d F sport not too long ago thinking i could undo the de-tuning and get those extra 30hp back but it looks like they changed the high pressure fuel injectors among a couple other things soits cheaper to facelift a mid generation (last of the 220d engine) F sport.
the 200d has the same common EGR and DPF issues though you can clean your EGR out every so often to avoid unnecessary issues with that and your DPF may not be as much of an issue as the internet leads you to believe if you drive the car hard enough sometimes and dont do nothing but short trips without fully warming the engine. my last 220d had a gutted DPF and EGR/DPF disabled in the ECU by remapping. my current 220d has the DPF intact and standard ECU so im conscious driving it but have not had any issues yet. i think i noticed possible DPF regeneration smoke once since i bought the car. i have a couple modifications done and as yet no issues. i will be getting the DPF gutted and DPF/EGR disabled with a remap at some point though as i want the remap for more power (my last 220d i got up to 383lbft/231bhp) as my current 220d is around the 345lbft/192bhp mark as thats what my last put down with the same mods before i had the remap done in conjunction with mods. on my current 220d im hoping to push up nearer 400lbft/250bhp if possible. i believe these 2AD engines are a serious underdog for tuning potential. there is no aftermarket like the VW TDI's or even BMW diesels but these 2.2 2AD's seem to respond very well to power adding mods and have the added benefit of an extra 200cc displacement vs VW/BMW/Mercedes 2.0 diesel 4 cylinders. i have done some experimenting and testing with intake setups on my last 220d, im using the is250/is350 F Sport lower airbox on my current one as well. the F sport lower airbox does not seem to cause the ECU to put up a DPF efificiency fault like the fully fledged intake i made on my last one did befire i had it remapped. i have been working on prototyping and potentially making batches of is200d and is220d intakes since there is nothing available currently, im still working on it but havent decided the best setup for both function and ease of use/installation, etc. and to make it in such a way where ideally it doesnt trip a DPF fault because then you need to get the ECU remapped to kill the fault. basically too free flowing on the intake and it upsets backpressure i nthe DPF that the ECU expects to see and triggers a DPF fault. happens on most modern diesels with a DPF. another issue i have encountered on and off not relating to the intake is a fuel leak fault where i believe too much fuel demand on the injectors causes pressure in the fuel rail to drop and i suspect the suction control valve on the fuel pump is not allowing enough fuel in to keep up with the demand. i have been looking at an aftermarket valve from a company in australia for tthe larger 3.0 toyota D4D as well as potentially modifying a used standard valve for experimenting but god only knows when or if ill get around to figuring that one out.
engine life wise.. really its just EGR and DPF that are the main issues so if you got those sorted and remapped you would really only need to do the routine servicing unless just bad luck sometime and a sensor or part failed, etc. these engines are more reliable than the internet makes you think. i have a facebook group for all the 220d and 200d owners as theres limited info out there so i want to create a sort of hive of knowledge and experience as the cars get older. its "the lexus is220d & is200d Emporium".

No problem. Info/knowledge on the diesels is severely lacking. I pillaged most of what i learned of the sensors and systems on the engine from toyota pdf documents for the 2ad engines in the avensis/auris sr180 or t180 as thats where lexus robbed the engine from.

The IS220d used the 2AD-FHV, this was sold from 2006-2012.
The IS200d used the 2AD-FTV, this was sold from 2011-2012 and replaced the IS220d in some markets.
Most of the engine is identical (block, head, all internals). The differences are external and fuel related only as far as I know. The turbo is different, as are the injection nozzles. The EGR and DPF are the same for both engines.

Hi!
One more question:
I use in my manual transmission SAE75W-90 API GL-5 oils. Should I use the same in the Differential gears? I know in the manuals is :LT 75W-85 GL-5 or equivalent.

Afeter some searching I can answering to my own question: yes, it is possible to use manual transmission SAE75W-90 API GL-5 oils instead of the LT 75W-85 GL-5 differential gear oil.
