1.9 multijet 150 egr valve removal / cleaning

first you will need a 10mm spanner or deep socket, a 13mm socket and a t25 torx bit and can of intake/carb cleaner and most importantly some gloves my hands are still dirty and safety glasses.now remove engine cover and locate egr valve at the top rear right hand corner of the engine joining onto the inlet manifold.

you can remove plug to solenoid now or when valve is off is a bit easier to get at it.
mine has a bracket fixed to it that requires removal first by undoing the two nuts with 10mm socket.next the two large bolts with 13mm socket were slackened off, then the remaining 4 bolts to the manifold were removed the 2 on the right were easy but the 2 on the left needed a spanner as my socket was not deep enough, there is a metal gasket between valve and inlet manifold dont lose it.next remove the 2 large bolts but be aware there is a metal gasket below valve between flanges, i kept and reused both of my gaskets but next time its cleaned will try to get new gaskets.

this was build up in inside of the inlet manifold looked same at 2mm or so, i did not disturb any of this as didnt want chunks going through my engine.

next you will need to split the valve into two by removing the 4 screws with your t25.i scribed the join of the two halves to make sure it goes back together in same position.

there is nothing you can loose out of valve body so now get it a blast of carb cleaner, i recommend safety glasses as i got quite a lot of splashback i also used a small stiff brush to help clean(just dont use one that will lose its bristles in the valve)

the solenoid half of the valve required minimal cleaning as its only leakage through the valve stem that gets in there.check for free movement of plunger mine was nice and free, i thought about spray lube inside but decided against it incase it gunks up so left dry.
all thats left is to reassemble the two halves and then refit valve in reverse order be carefull with gaskets.

i decided not to clean the exhaust gas pipe, will leave that for next years clean but if you decide to do it it looked like a 5mm allen key is required to undo a clamp down below im guessing theres a gasket of some sort in there and would need realigning upon refitting.
not sure on correct diclaimer so follow this guide at your own risk.

Re: 1.9 multijet 150 egr valve removal / cleaning

Well did mine today it was in one hell of a state after 30000 miles it looked like it had been buried in a caol mine. But after 2 bottles of carb cleaner and a toothbrush its sparkly clean now. only prob i had appart from losing the erg manifold-Gasket somewhere in the engine was the engine warning light came on with the massage "engine problem" or something. But after a blast around the block and i mean blast the car goes like a rocket now the warning no longer comes on, must have needed a blow out.

This is how bad it was... I should have taken a pic of "inside" the egr valve, but you get the picture

Re: 1.9 multijet 150 egr valve removal / cleaning

I have a question... i recently cleaned my EGR out on my 150 M-Jet... yet on the part of my valve where the spring is (i.e. the bit pictured above) it was completely clean? not so much as a trace of soot. Does this mean it's not working as it should, or that its working correctly?

Thank you

I did the same mate and my engine light came on, telling me the sensor is not detecting enough preassure... or something like that. Had to take the blanking plate off which sucks. Reseted the engine lights a few times before doing that but no luck, not until plate removed.

Any idea how to avoid the engine light failure much appreciated.

Re: 1.9 multijet 150 egr valve removal / cleaning

cheers for the guide! Just did the EGR valve on my Bravo, and she runs much smoother.
Was driving home from work a couple of weeks ago, stopped at some lights. When I attempted to take off, the engine lost pretty much all oomph, and I blinded the guy behind me with a nice load of soot. At first I thought the turbo had crapped out, but reading of similar experiences on this forum, I started to suspect the EGR - now its cleaned, everything back to normal...

Re: 1.9 multijet 150 egr valve removal / cleaning

Many thanks for this guide!

I had my EGR valve replaced due to this 2 years ago / 20,000 miles ago. It had been playing up again the past few weeks, so with the help of your guide I was able to take it apart and clean it, rather than spend a fortune again. The plunger was rock solid on mine until some force was applied.

She is driving beautifully again.

Re: 1.9 multijet 150 egr valve removal / cleaning

Hi

I notice that you did not clean the inlet manifold in case chunks went into your engine. Is there a way of cleaning it off without that happening? Also if it did, would it be damaging in a big way? Thinking of doing mine as it is really bad. I had a new one put on at 67000 miles, now on 107000, but it has been giving me intermittent jip for the past 20000 miles. Do you think this is quite straight forward to do i.e. what is the worst that could go wrong? Thanks!
