Always use some high temperature anti seize on those EGR bolts. To avoid spot corrosion, cover them end to end.

[@richardnorris3095]

Will have a go at doing this to mine , thanks for the vid George 👍🏻😎

[@toooldclassics]

I find your videos really helpful :>) I replaced my EGR valve on my 2010 E92 N47 2.0 diesel just recently. The EGR valve is a different type and it was a pig to get out. Both torx heads sheered and needed to be drilled and extracted out. The OEM replacement EGR value part had longer coolant pipes that fouled the cooler so ended-up having to shorten and file to ensure a fix. One of them snapped and left part of the pipe in one of the EGR valve coolant canals so that needed to be extracted out too. The interference fit of the EGR value and the exhaust manifold is very tight so ended-up using some copper grease to ease fitment. All sorted now thank goodness. Your videos gave a great step by step guidence.

[@liamcooper3922]

More patience than i would have had well done.

[@toooldclassics]

By way of an update: the OEM EGR valve I fitted isn't OEM after all. It looks original but sadly seems to be an imitation. It is failing after just over one month of problem free motoring. The fault codes that my cheap mobile phone app (Torque Pro) can detect comprise 1) Insufficient gas flow detected from EGR valve 2) EGR valve stuck open 3) EGR valve stuck closed (yes really). As a consequence, the engine has stalled a few times and can idle rough at times. Disconnecting the EGR valve electrical connector triggers the engine management light in the dash but has eliminated the stalling and rough idling so far. This suggests to me that the EGR valve is operating outside of it's expected operating parameters (or at least it's electrics are communicating that to the ECM or PCM maybe?). The ERG valve will need to the replaced with a BMW original part I suspect. That'll teach me not to try and cheap skate on eBay with procuring some junk intimation part.

On my Lexus diesel the bloody EGR was solid with suit. Its a fine needle that sticks. I used methylated spirits (works really well to remove carbon) and a scraper and electric toothbrush, don't bend the needle! It will make your car run smoother and avoid puffs of smoke coming from exhaust when you apply throttle, that;s my experience anyhow.

[@tigerseye73]

Except for some soot on the valve, there should be no reduction in its intended job performance. I believe this was still fully functional and did not require cleaning at this point in time.

[@stevensimmons7462]

There's no point in waiting for it to fail before you do the work. Always easier to do it in your own time

I have a 2012 bmw x3(f25) 2.0d. N47 engine. I was driving the other day the car started jerking for a few seconds and then went into limp mode with a drivetrain message on the idrive. It was still ok to drive but with a loss of power. Once i switched off the engine and restarted it 5 mins later the warning had gone and the car drove normal again....the following day it happened again. I checked errors with my code reader and it gave 2 faults to do with the egr valve. Drove it for 2 days after this with no errors or warnings but I'm sure it will pop up again soon. Do you think I need to do the remove and clean and replace on mine?

I did mine then looked inside the inlet and had to buy a spare inlet manifold because it was so clogged up. And had to clean out all the inlet ports on the engine. Can't belive how much these clog up.

George, I'm going to make a start on this on mine. I regret not doing it once I discovered the engine light that keeps going on and off. Scan said egr. However yesterday on the roundabout I dropped to 2nd gear and floored it to 40mph, the car when bang! As if pressure built up and blew out the exhaust. Car then went on to half engine power mode. Parked up had a look couldn't see nothing. Got to my location with half a power doing 30mpg. I discovered the manifold actuator "arm popped off" the bang was it didn't open the swirl flaps and pressure built up. So causing the arm to come off. Now I've glued the accuator arm back on. Feels like the small metal clip that holds the spinning bit is lost for ever. Should I clean the egr cooler aswell? Since I am cleaning the egr itself.

Don't suppose anyone can tell me if my 1998 volvo d5252t tdi has one?

hi George just quick to ask what will happen if I remove the EGR valve on n43 engine (petrol) cheers

[@MrMaximo10]

can someone answer the question please

[@0cypher0]

@@MrMaximo10 unless you combine it with a complete remap, your NOx sensor is likely to send your car in limp mode, your fuel consumption will noticeably go up, with the N43 being a lean-burn engine, overfuelling will pretty quickly destroy the cats, on top of that the engine will have an increased chance of knock and you won't pass emissions testing as the CEL will definitely keep turning on and NOx levels will be above Euro 4/5 limit depending on your model year. I'd be more worried about the timing chain and guides, oil pump and injectors than an EGR delete on an N43.

In most of Europe you can't pass technical inspection without egr sadly

Would you prefer to breathe more NOx then?

Question people ... my dpf was modified before I brought the car.. basically my question is if my dpf has been drilled out and I'm getting that funny blocked dpf smell could it be my egr valve causing that same smell? Any info would be great m.o.t in 2 weeks and don't want it falling on emissions..

[@GeorgeAusters]

You will have a diesel smell with DPF removed, it’s normal

[@tomschwer4294]

@@GeorgeAusters is that the same smell you get when dpf is blocked?

[@makantahi3731]

and on petrol engine too

Unfortunately mine is stuck fast onto the engine, even a tap from a hammer won't budge the thing, just wondering how I'm going to get the thing out to clean it ...
