SaFas: South Africans

All SaFas get their intercooler from the UK, usually from Allisport or AliveTuning, the local products are just not goof enough.

BTW, I live in Stellenbosch. If you want to see a Puma with BAS remap + Allisport intercooler, give me a shout  --

I have a Defender Td4 2007 with 165000 km on the clock. All is well, except that sometimes, especially in the long ramps with the throttle pedal down (I'm still in charge over 3,2 tonnes), there is a loss of power: first, the engine looks to limit around 2700 rpm and if I keep the pedal down, it goes in extreme limp mode (about 800 rpm), the temp needle sharply rises into red and there is no MIL amber light.
The temperature stays high for around 10 or 15 seconds, then comes down back again rapidly to normal, the problem disapeared and having a “cool” driving, I can once again have a normal driving.
When a slight loss of power occurs, if I put a lower gear for having a small reserve to accelerate, it does not turn onto limp mode .
This occurred the first time in the Dolomites in Italy (km 55 000 on the clock): the EGR valve was changed, fuel filter and thermostat changed, MAP and MAF sensors cleaned, water pressure system is OK, ... and every time, none fault codes with the scanner.
This occured several times: in Brazil (km 60,000), in Chile in Paso del Libertador (km 90,000 ) , in the Ethiopian mountains (km 140,000 ), ........ Now, I'm in Cape Town, Africa South.
For more information, in Ethiopia, under the same conditions, another TD4 (year 2010 and 60000km on the clock) had the same problems as mine, while the third TD4 (year 2008 and too 60000km) was OK?
If anyone can help me because I'm always looking for a solution.
Thank you so much

there are (depending if your car have ABS or not) it is the 1st (w/o ABS) or the 2nd (with ABS).

Check the socket contacts (they must be solid) and the relay teperature after 10-15 min of drive.

When the water temp. indicator is going to the RED zone, normanlly it is a problem "main relay" related.

Sounds like you are gunning it in 6th and the ECU is cutting power to prevent damage to the engine.

Lots of SaFas had this issue as well, cured by fitting a bigger intercooler.

Should be, but the strange things is the Water temp on RED (comon on main relay related failure) with normal H2O real temp Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Yes, it occurs when I'm gunning on 6th but why my water temp on red ? and how to know the real water temp?
I think there is only one sensor CHT on the back of the engine cylinderhead

It is an electric problem related!!! Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Don't gun it in 6th when towing uphill, rather gear down.

The only way to know the coolant temp is to fit a Madman-type engine monitoring system or read it off with a Scangauge/Ultragauge --

Mongolia,

I've experienced both the intercooler and relay issues discussed above.

If I was travelling up long inclines in 6th gear at altitudes over 1,000m above sea level in warm weather (30+ degrees) the vehicle would go into limp mode. It would cut back power and I wasn't able to get the revs over 2,200 rpm in 6th and 2,500 in 5th if I geared down. The temperature gauge would not move and no MIL light came on, nor were there any fault codes stored. The only solution at the time was to throttle back and take it slowly. I fitted a new intercooler 6 months ago and the problem hasn't resurfaced.

The relay issue would happen at any time, even just after start up. The temp needle would shoot off into the red and the vehicle would cut out. This got progressively worse over a couple of weeks, until Land Rover replaced the relay. They diagnosed the fault quickly so maybe it stored a fault in the ECU, but I can't say that for certain.

Replacing the relay is certainly going to be the cheaper option, but it may not be the cause of your problems. The intercooler issue is known to Land Rover South Africa, but they are of the opinion that the standard intercooler is good enough - there are plenty of us who disagree, including workshop managers, who ostensibly work for LRSA through their franchises.

You need to be very clear on the conditions in which your limp mode occurred, if it was random have a look at the relay, but if it was hot and at altitude and the vehicle was under strain, the intercooler may well be your problem.

PS. I imported my intercooler from Allisport in the UK, but there is a local version (the core is made in Europe) for sale, which is significantly cheaper.
