Limp mode, egr valve issue, blanking plate fix?

So, 2 weeks and 2 issues with the evoque but only had one other issue in 3 years or so can’t complain too much.

Had an intermittent limp mode but kept rectifying itself over a period of weeks. Car did feel down on power when required. Then went into full limp mode one day. Called AA and they were excellent. EGR valve issue. They Couldn't access egr valve easily as were trying to un plug it, so fitted blanking plate. Car drives great now. Googled it and appears to be a common mod.

What are people’s views on blanking plates on sd4s? I’ve read cleaning the egr valve can rectify it. What have people done when experiencing this? Is the egr valve difficult to remove?

RE: Limp mode, egr valve issue, blanking plate fix?

Surely if it's blanked the ECU will complain about incorrect pressure detected when the EGR opened?

Have you tried a fuel cleaner like Archoil that might get/keep it clean.

I ask as my other halfs Volvo has just had the check engine light, EGR pressure code come up, and am trying archoil to see if it will clear it first.

From my googling some cars seem to throw a code, some don’t If blanked. Mine hasn’t. Seems a popular mod, and if you believe what you read increases mpg, performance, cleaner dpf Andy other bits.

I’ve not tried a fuel cleaner. Would a fuel cleaner clean up the egr with the blanking plate in place?

Re the Volvo, the blanking plates seem to cost 2-3£ and take 5 mins to fit so may be worth trying?

Hi Nickj,

How is it going now without the EGR shoving dirty air back in?? Is it still running good with better MPG without any warning messages?? I will be looking to do this on my SD4 soon , can you get the EGR deleted from the vehicle? Any info would be greatly appreciated.

Cheers Bazz

Hi Bazz, funny you ask. No, blanking plate seems no good on 2.2 sd4. It’s still occasionally on a longer run going into soft limp mode. Also has no low down power, so really laggy when you pull away. Think I either need to try a blanking plate with a hole in it, fix the egr or get a cheap remap that deletes the egr valve.

Hi Nickj,
Very strange, you would have thought it would be better with nice cold fresh air going in, you may well be right about EGR fix or delete. Bloody JLR stuff you which ever way you try to go -- but I don't think it is insurmountable with a bit of electrikery change in softwareWink. I am sure someone here will know the way to go, please keep us informed.

Good luck.

RE: Limp mode, egr valve issue, blanking plate fix?

I bailed out of my 2014 Dynamic Lux Plus after only 9 months due to continual DPF issues after a software upgrade but the problem was failing DPF sensors all the time, like every 10 days.......... JLR told me it wasn’t a big problem, just keep booking the car into the dealer every 10 days after LRA had recovered the car. After posting about it here LR stopped doing the software upgrade until they had a fix for it. It turned out to be a problem caused by a software update done to the 9 speed automatic gearbox software........ made and programmed by ZF

Are there not MOT failure issues with blanking off EGRs on cars designed to have them now?

Now driving a 2018MY Mini Countryman Cooper S E All4 PHEV, alongside my 1996 Defender
TDi300. I hope to be back in a new Land Rover in late 2019 or early 2020 but am having a short break
