Does your Land Rover Discovery or Defender TD5 suffer from hesitation and a flat spot?
Do you feel the engine is being restricted?
Is your engine less responsive than it used to be?
Belching out black smoke?
Your Land Rover Td5 could be suffering from a faulty EGR (Exhaust Gas Recirculation) valve. The EGR valve is a very crude device that diverts spent, hot, exhaust gases back into the inlet manifold to dilute the fresh clean combustion air.
We all know that to get maximum performance and economy from a diesel engine, you need to get as much air as possible into the combustion chambers. All modern diesel engines use a turbocharger to compress and force more air into the engine. But compressing air heats it up and makes it expand; this is where the intercooler or charge cooler comes into effect. It cools down the compressed air making it more dense so that the maximum amount of air or more importantly oxygen can be forced into the cylinders so that the injected diesel fuel can be burnt more efficiently, producing more power and better economy.
The EGR valve does it's very best to counteract all the things required for maximum performance and economy. The first thing is the actual physical restriction the EGR valve causes downstream of the turbo and intercooler. When the EGR valve opens it allows hot exhaust gases and carbon to flow into the cold, compressed air, making it less dense and diluting the oxygen within that air. At the same time it is robbing the turbocharger of hot exhaust gases to maintain the boost pressure. The exhaust gases and carbon coat the inlet pipes and manifold with a tarry substance that can also restrict air flow. And all this is happening when the EGR valve is working correctly!
If, as quite often happens, the EGR valve fails, it usually remains open all the time robbing the engine of power. This can cause a noticeable loss in power, an increase in smoke and reduced fuel economy.
So you are probably wondering why the EGR system was fitted in the first place. In summary the EGR system is a way of reducing NOx emissions that occur in all combustion engines. NOx is produced when nitrogen and oxygen mix at very high temperatures. Car manufacturers fit these EGR devices to meet strict European emissions regulations but they are not a requirement for the UK MOT or emissions test so can safely be removed.
The best solution is to remove the EGR valve completely, this kit, supplied by JGS 4x4 contains everything you need to remove the EGR valve, safely and easily from both Defender and Discovery 2 TD5 models.
Will NOT affect MOT or emissions test. There are some cheap blanking plate only kits available but these are not ideal, the actual EGR valve is a restriction to air flow and is best removed completely.
The JGS 4x4 TD5 EGR removal kit is a complete solution, the kit contains everything you need, includes the following items:
EGR Valve removal cone & gasket (5mm Precision Laser Cut Steel)
Blanking plate & gasket (5mm Stainless Steel Precision Laser Cut)
EGR solenoid vacuum Blanking Plugs x 2
6 x Stainless Steel Cap Screws

Early TD5 models have a stainless steel EGR pipe running across the front of the engine from the exhaust manifold to the EGR valve. This pipe can be removed completely and the blanking plate and gasket used on the exhaust manifold. Later TD5 engines incorporate a water cooled heat exchanger into the EGR pipe, this cannot easily be removed and is best left in place. The blanking plate and gasket can be used on the EGR valve end of the heat exchanger. The EGR removal cone replaces the EGR valve with a straight through pipe, removing the restriction, allowing the engine to breathe more easily. This cone has a hose retaining bead to prevent the turbo hose coming off under pressure.
The EGR valve is controlled by the ECU and is operated by 1 or 2 small vacuum pipes depending on the year, controlled by either 1 or 2 solenoids. The small vacuum pipes connecting to the EGR valve can be removed and the connections on the solenoid blanked off with the supplied rubber blanking plugs. The ECU continues to think that there is an EGR system fitted and will not throw up a fault code.
Can be easily fitted by a competent DIY mechanic, if you have any doubts how to fit this kit, seek professional advice.
