LC200 'UK Spec' Engine Failing in Asia

[farhanazim]

Dear Friends,

My family owns a 2012 Land Cruiser 200 which was purchased brand new from UK and then shipped to my native country Bangladesh (in South East Asia). The vehicle came with a 1VD-FTV and had Diesel Particular Filters (DPFs) along with Exhaust Gas Recirculation (EGR). Just for your general information, despite having a Toyota dealership in my native country, my family still chose to import from UK as the UK version was more upgraded (air suspension, wheels, interior features) than the spec that was offered through the dealership in my native country. It is important to note that the LC 200s offered through our dealership had the 1VD-FTV engines but did NOT have the DPFs (and probably also did not have EGR). It is also important to note that there are plenty of LC200s in my country that were sold by the dealership.

Now with regard to my LC200, the issues are chronologically outlined below:

1) The DPFs started giving errors from about 13,000 miles

2) I did a DPF delete through installation of an emulator at about 14,500 miles

3) My engine failed/ceased at about 16,000 miles in the year 2016

4) As per the guidance of my authorised service centre, I installed a brand new engine, 2 brand new turbos and another set of brand new DPFs in 2016.

5) In the same year also installed a set of brand new catalytic converters.

6) The DPFs started giving errors again at about 25,000 miles which is when I deleted them again and installed a new set of emulators.

7) The vehicle now has about 32,000 miles. The engine again became extremely (and embarassingly) noisy with a loud, knocking noise bt no vibration per se. It started giving check-sign errors. The fault code is P1605. Every time the fault code is deleted, the engine would run fine for about 20 or 30 km but then the sign would come back and the vehicle would become slow and heavy.

This time I took it to my known third party service centre which took the engine apart. As per the third party service centre, the engine’s bore as well as the connecting rods were damaged. As per the service centre it is due to the diesel in my native country (which I must confess is certainly of an inferior quality than the diesel in UK) not suiting the UK version engine (despite my local dealership LC200s also having 1VD-FTV engine). The service centre concluded that I need a new engine block and one of the turbos.

Additionally, although the part no. of the engine block against my VIN is 1140051030, the part no. of the engine block against my native country’s dealership version is 1140051020. My third party service centre suggesting I go forth with 1140051020 instead of 1140051030.

I am requesting members of this great community to kindly shed some light.

*Is the 2012 UK version 1VD-FTV really different than that in the LC200s that were sold in South East Asia?

*What could really be the main issue due to the repeated breakdown of my engine at such low mileages?

*Is it going to be okay if I install 1140051020 instead of 1140051030? Will it be a direct bolt-on? Will it require any ECU tampering?

*What is the difference really between 1140051020 and 1140051030?

Wow you are not having much luck. Sorry I can't help you very much but I know that in Africa they have 2 types of diesel which have varying amounts of sulphur. It may be worth trying to join a forum in South Africa as they have more experience with 200s and the differing specs and fuels.

Good luck with it

As Stumog suggested it’s worth visiting SA forums. I remember reading discussions in those forums about Sulphur content tolerance for these engines.
It’s worth checking if DPF blockage is the root cause of engine failure. If so, the damage is likely to repeat again.
UK has less than 10PPM sulphur content and the recommended concentration for these engines is less than 15ppm.
Here even the engine oil I use is low SAPS oil.

I remember from forums that 500ppm (LSD) can be tolerated if driven long enough distances in a go regularly.
There are places where high sulphur diesel is still used (2500ppm).
It’s worth checking if local diesel quality, engine oil and driving style are linked to the issues you are facing

So, so far the decision is as such that we are going to replace the engine short block since the cylinder bore diameters have been affected. Now the engine short block part no. against my vehicle’s VIN is 1140051030. However my third party service centre is insisting to proceed with the engine short block with part no. 1140051020. This alternate no. (1140051020) is related to the general export models which do not have DPFs or EGR. According to my service centre the alternate engine short block will be more durable in the long run. But I am wondering whether: i) it will be a direct bolt-on installation, ii) it will give rise to any errors on the dash or fault codes. Can anyone provide some information?
