Thread: 2014 DEFENDER ISSUES

Brilliant!

I took delivery of a MY14 110 wagon in April 2014. I now have just under 24,000 km on the clock and have had a total of zero issues so far.

Let's hope it stays that way

Fair enough Pat, but in terms of the balance of my question, why do owners disable it, and are there any dangers in doing so?
Pickles.

They disable it because it's been proven without question that engines run better without them,the sluggish hesitant traits of many engines are caused by the EGR. Pat

Thanks, Like a lot of "anti-pollution" stuff,...I can understand that.
Finally, are there said to be any "dangers", or anything of a negative nature that could occur to the engine, that could be attributed to this, in any operating circumstance?
I did say I was "mechanically hopeless"! Pickles.

By disconnecting it all you are doing is making the engine the same as any other pre 2000 or so diesel engine,going off the experience of the Td5 which was the first LR engine to have an EGR and the first to be disconnected it'll pull harder,get better economy,run smoother and in pretty much every sense be better.

just recently bought into a BAS remap primarily to disable the EGR after reading for months many stories related to how the normal means (blank it off) don't work so well on the TDCis.

Exchanged emails with Pete Bell about this how his remap might get me to where I want to go (EGR always closed and no MIL lights or other issues).

An interesting comment he made at one stage was that the TDCi ECU does make "emergency" calls to the EGR (to open up) to protect the engine (my assumptions: by lowering power output & combustion (?) temperature when it is deemed such action is needed.)

Thus a benefit of (his) remap is that in normal operation the remap may call for 0% EGR open. However if a critical situation arises and the ECU wants to deal with it by opening the EGR to lower power output and combustion temps - it still can.

Sounds pretty reasonable and sensible to me.

^^^ The reason BAS and Alive are so highly rated,I bet the chip makers don't have that. Pat
