05 2.2 EGR, loss of power, management light, oil l - DSRenault
Hi Folks,

I am the latest in the line of unofficial development engineers for the famed Espace 2.2DCI, however I will not be beaten by a mere machine (hopes).

In six months I have been through two EGR valves, prior to the last change oil was finding its way out of the valve connection to the induction pipe/hose and of course was loosing oil though not at a tremendous rate - also along with this the management light would come on under mid to high load and the turbo would cut out until the engine was turned off.

Took the car to a specialist and eventually to a main dealer who both diagnosed that the EGR valve (the second by this time) needed replacing as this was causing oil to be drawn through.

Valve changed pipes cleaned and all was well for about 1-2 months then exactly the same problems happen again with the adde bonus of oil appearing somwhere out the top of the engine as the underside of the air intake box is covered.

I have booked the car in at a different garage (one with a lot of experience with diesel engines) for Monday but wondered if anyone could add to the list of things I will ask them to look at below:-

Clean EGR valve and pipework as required (possibley replace)
Oil and filter change to fully synthetic
Check breather pipes (top near injectors)
Check turbo, bearings seals etc.
Check turbo hoses
Check inlet manifold
Check and replace brake light switch and reset

Any thoughts would be much appreciated.

Cheers

Really there are so many problems with these motors its just untrue. It would be a waste of time speculating what might be wrong without access to fault finding kit. Best leave it to a professional with a bit of experience to take a look at it.

I have been to a Renault Specialist and a main dealer - I think that the fault finding kit cannot tell you if there is an oil leak through a gasket for example.

The last time the car was plugged in it was coming up with a turbo sensor fault.

It has also been suggested that the ECU could becutting out the turbo in a safe mode if if detects lubricating oil getting in the cyclinders.

I have had exactly the same issues with my 2005 2.2 DCI Espace. Every 6000 miles the EGR valve packs up. The signs are:

- A big puff of smoke comes out of the exhaust when trying to accelerate. Usually on the motorway.

- Loss of power.

- The car will continue to drive otherwise normally, when you get it home you will notice that the oil level has been reduced by a few millimeters. I just happened to check before the issue occured.

Take the car to the garage (I use an independent one) and get them to clean out the engine pipes\hoses and replace the EGR valve and obviously the oil.

It will run fine again for another 6k miles. If you do not identify and attend to the issue quickly the engine oil will get into parts it shouldnt and all sorts of signs will show up in the engine management system e.g. check injectors.

I wonder why you need to replace the EGR so often when cleaning it and the throttle chamber in particular, are all that is usually required every year or so of motoring. Could be that the turbo "seals" are wearing out of tolerance and starting to allow excessive oil through.

Took the car to a specialist and eventually to a main dealer who both diagnosed that the EGR valve (the second by this time) needed replacing as this was causing oil to be drawn through. My comment : never heard of this before. Seems unlikely.

Valve changed pipes cleaned and all was well for about 1-2 months then exactly the same problems happen again with the adde bonus of oil appearing somwhere out the top of the engine as the underside of the air intake box is covered.

Symptoms of: blacked oil breather causing cankcase pressure to push out oil or worn rings ditto.

I would try removing and cleaning the crankcase breather first - as it should be cheap and easy.

Failing that.. although the turbo has been checked, worn turbo seals.

Does it burn much oil?

The most likely cause of your problem is the inlet manifold as these are pvc they have a habit of warping and are prone to hair cracks these manifolds need to be removed and checked across the 4 inlet ports using a straight edge.Amost common fault on these 2.2 models symptions caused pressuring the sump Hth Regards Mickeybo

I have the exact same problem with my 04 Espace 2.2 dci. Occassional Big and i mean BIG puff of blue smoke. Car drives perfectly otherwise. Did notice , when i serviced it, EGR valve was stuffed with oil sludge. Removed and cleaned it. Not sure what probable cause is? Can faulty EGR valve draw oil into induction pipes? Is Turbo most likely problem? It seems to be working fine, no fault codes. I know inlet manifolds can give trouble, doesn`t have any crankcase pressure issues. Any suggestions would be appreciated
