2011 Defender 110 Puma 2.4 SW Stornoway Grey

engine has a flat spot @ 2000rpm

Ive had my puma 110 for a year now it has 6,600km on the clock now, and ive noticed today when coming back from the Airport that when i was moving off in traffic I got this flat spot @ around 2000 rpm. no warning light, nothing like that just feel as if its not right.

If it is no remapped, chech the EGR valve.....

1. Switch off the engine
2. disconnect the EGR valve electric connector
3. Test drive

4. Switch off the engine
5. connect the EGR connector

if at point 3 the flat spot is disapeared, it is the EGR Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Drop it into Davis Performance and let Bruce take a look. Which then will be passed onto me, to have a look!

I would suggest that you confirm the EGR is working first before disconnecting the EGR plug. Check that it completes the self test cycle (5x chukka chukkas) then disconnect. That way you know that the EGR valve is closed. If it is at fault you should have other symptoms though
