What do bad injectors (usually caused by dirt or water in fuel, not high sulfur) have to do with low compression (usually caused by bad rings or valves)?
Could GO be gazoil? Accumulation of fuel is definitely caused by bad injectors unless you have a Euro 5 or 6 engine in which case if it has "in-cylinder regeneration cycles" it could be a symptom of a malfunctioning emission system (extra fuel injected in exhaust cycle to burn soot out of DPF).
If your Defender takes DEF it also probably has a DPF. You DO need to buy the euro diesel unless you delete your emission system which usually also requires software changes. There are many vendors in the States that supply this for US diesel pickups but I had to look hard for someone that can do it for my diesel X5. I don't know if this is available in Europe due to EC wide inspection requirements. Alaska for example does not require emission inspections, most of California (but not all!) counties do require it, also many other states. Canada not so much.
Roro, it is possible that your engine was ruined by the engine's attempt to follow the emissions software. Usually damaged injectors due to dirt/water will produce gradually increasing easily recognized symptoms like missing, loss of power and lots of black and/or white smoke. Which will further instigate the emissions system to do more and more soot "burnouts".
Iran and parts of Africa have some of the highest sulfur diesel in the world - some places 10000 ppm! This will quickly damage/destroy a DEF/DPF type emissions system which will cause various (bad) effects on the engine as "side effects". As I have repetitively written previously, the sulfur does not damage the engine directly (except that it uses up the alkalinity of the lube oil much more quickly and then acidity can cause internal engine damage if the oil is not changed/replaced with high alkalinity oil [ACEA E4/MB228.5]) but it will eventually destroy the emissions system at a rate dependant on sulfur level. Then the "side effects" can destroy the engine.

Sorry for my bad english...and thanks for your reply.
Yes GO means Gaz Oil (diesel).
I'm going to try what my mechanic told me:
Bad diesel causes dammage to injectors first.
Then bad injectors fill cylinders with diesel and this causes bad lubrification then bad compressions.
Sorry for these incomplete explications because I don't know english terms for them.
I don't know if my Def TD5 is Euro 5 or 6 , it was made in 2006.

Dirty or watery diesel does damage injectors but that has absolutely nothing to do with the sulfur content; just the cleanliness. The prevention is to have at least 2 fuel filters with the primary having a water trap, and to check it very soon after a fill-up. Secondly to always try to buy fuel from reputable outlets, not out of drums etc.
A 2006 vehicle is euro 3 or at the most 4, but you said it took DEF (AdBlue) which is usually euro 5 or 6?? If your vehicle does not take DEF or have a DPF (diesel particulate filter) you should be able to burn high sulfur fuel no problem. However, especially in view of your experience, I would fit a primary filter with water trap like a Racor:

BTW, we've just had a bad experience with fuel in Kosh-Agash. We filled up (200 liters!) at the АЗС station. It's just another of the many modern petrol station in the village, not cheaper than the other ones, chosen at random.

Just after crossing the border, we've had a stuttering engine and white smoke coming off the exhaust. So we've just drained all of it and replaced it with fresh diesel from Mongolia ("Petrovic" seems OK). Seems much better so far, no damage except for the wallet.:oops2:

Maybe the bottom of the tank, or a bad batch. Shit happens. :rain:

TD5 IS a common rail diesel and you should always try to get the Euro Diesel. Older Cruisers and mechanical injection Rovers are fine on regular diesel.

As above, fit a 2nd filter with water separator if you have a common rail diesel, that is pretty much a necessity.

I know no stinkin' TD5, mine is an HZ1, 4.2l 6cyl Toyota. :oops2:
Rock solid.

And yes, I have also installed a Raccor water separator, even without a common-rail it helps. Sometimes.
