Good morning all

My 08 Doblo 1.9 Multijet 105 appears to be suffering from EGR syndrome
It has run off power for a few months while l found the time to take it off.
I did it yesterday and cleaned it out but never split the actuator from the body and didn't get the needle moving, so really job not done. From reading on this forum l have decided to fit a new one as it was a right fiddle taking it off and not something that l want to do on a regular basis. The car has done an priginal 30000 so a little surpirsed to have this problem so early.

The guides here were priceless on how to remove it, thanks for that.
On this engine the bolts underneath were not Torx but 8mm allens... so not knowing this until l got it off and being unable to release them i took off the drop tube at the next joint removed it all as one lump then seperated them - why did the clamp bolt get fitted from below when you can't get to it because of the gearbox. I have re-fitted it with the bolt accessible from above with extensions on a 1/4 drive socket.

What l would like some help on is where l can get a new EGR at the best price. Initial searches reveal £140 to £54 , but not sure the cheaper will fit a multijet as it says JTD version. Any advice from the helpful forum greatly appreciated.

Thanks to all

Re: EGR Valve

i would either fix it, or get a s/h one. at 30,000 you probably have another problem clogging it up, like oil from leaky turbo seal being thrown in. I took mine apart at 100,000 with it sticking.

if the solenoid is not done, then they can usually be sorted with enough cleaning agents. Now before every mot I just spray some EGR cleaner into the valve end(as well as inlet chamber of engine).. without removing the entire thing.. emissions are always fine now.

I get good parts from these guys. They stock up on common parts, then check the operation before they send, and you can get refund if not happy.

Re: EGR Valve

Thanks for the advic e Crinkle
I succumbed to temptation yesterday and took it off and cleaned it, pin was stuck and lots of sooty deposits, cleaned it and refitted.
Drives better but still feels a little off, although l did have 200kg of ceramic tiles in the back...
I disconnected the multi pin plug to see if the MAF was causing some loss but it ran worse so reconnected. Injector light came on and has stayed on despite doing three starts with it reconnected....
Is it worth fitting a blank plate to this engine, all the advice l have read on the Forum is for the JTD engine not the multijet? If so a solid plate or with a hole in it?
This seemed to start after l changed the oil and fitted 5w40 fully synthetic oil, thinking it was better protection, but wonder if if was too thin and was getting passed the rings. Anybody else had adverse outcome from using this grade or synth oil?
Disappointed with this, l have run diesels from the eighties, Citroen, Peugeots, BMW and Mercedes all with no problems at all, this is making petrol engines more inviting again.
Looking forward to some help and thanks

Maybe but those vehicles would never be allowed on UK roads with todays tight emissions so you can't compares cars from 30 years ago to the modern car.

1980's l meant!!!
The Citroens were Picvasso C4 with less than 120 on the governments richter emissions scale,Peugeots were 405's then 406's TD, the BMW was a 59 plate company car 316D - below 99 and £30 rfl, the MB is a C220 CDi still on the fleet.

I do much less mileage now and petrol is becoming the better option than diesel with all the trickery, EGR's DPF's etc which roll over and kill the engines in urban traffic.

I was really pleased with the Doblo, the cavernous boot and the reasonable driving, but the fuel economy is unimpressive compared to the easy 55+ of the BMW and the regular 45+ of the MB, and too many members are reporting simialr symptoms which don't seem to be diagnosed and remedied by dealers more trial and error till they stumble on the cause.

Will stick with this one now and try to make the best of it.
Blank plate next on the agenda.
Have ordered a Multiscan, should be with me this week.

Thanks for the advice and help from all

lol sorry I read your post as 'from' the 80's.

I get 52-55 from both my doblos average after a month which is around 1000 miles, thats local and motorway driving.

Members (of FF) report similar faults because thats why most people come here the same as if you went to a Ford/renault forum etc you would see a pattern of faults. I like known faults as you have a better chance of diagnosing them....I have spare column switch, map sensor, boot handle/lock in the shed Nothing worse than obscure intermittent faults.

I find them very versatile, nothing can tick the boxes (for me) like the doblo does ut each to his/her own I guess. I work on them daily and find them comparable in terms of reliability as any other car in its class, after all taxi drivers use them and they don't like spending money

Thanks again T14086 for your reply

Agree re other forums, l belong to the MB owners club and as you say similar postings there.

I suppose it is just frustration at diagnosing the fault, once that's done l can fix it, but don't look forward to doing johnnie Cash...one piece at a time!

As you work on them l would aprceiate your opinion on my next move

Looks like it was the EGR, once cleaned l have lost most of the cloud that followed me follwoing a burst of throttle.

Is it advisable to fit a blank plate to the 105 1.9 Multijet, advice differs on the forum?

Could the 5w 40W fully synthetic oil be an issue and shoud l revert back to a different grade, another post was asked what grade oil he had fitted?

Lastly, where does the plate go at the top of the EGR or the bottom pipe?


I hope once done my economy may be simialr to yours, but so far max has been 43 at 55mph on a 200 mile trip, but more often in normal driving high 30's low 40's if lucky. I'm not a white van driver...though used to drive fire engines some years ago!


Thanks again for your posts, great to get advice

Remove the 2 x 7mm allen key bolts at the EGR going to the small metal pipe and remove the metal gasket, replace with blanking gasket (do not use swirl gasket) and road test.

I have used cardboard blanking gaskets as a quick test however as you are best to try it out for a day or two then use metal. you can used a coke can or similar if stuck but best to use something a little thicker.

Thanks for that. I have ordered the plate and will fit at weekend.
Be great to get it back to what it used to be, i'll report bak on the outcome.

Best wishes

Hi all
Fitted the EGR blanking plate
What a difference thanks for the advice T14086

The Maxiscan MS300 sends a linking error so won't read codes, anybody else had this problem?

The injector warning light is still on, will see if it stays on after three overnight cycles

Best wishes

what am i missing here, why not just remove the power plug that goes into the EGR ? If the valve cannot open this is the same result as a blanking plate ?

Electrically yes, mechanically no. Is plunger complete or damaged even snapped...is it open or shut, you don't know.

you can tell what its doing by removing the front pipe and revving the engine.

Anyway i thought the idea of blanking the EGR was not related to its condition... blanking it is to stop it operating whether it works or not for performance reasons ?

So presuming you disconnect the cable, then rev the engine and check its not opening. so whats the difference between that and blanking it off ?

The OP done it to see if the EGR was faulty, why don't you try 'electrically' disconnecting the EGR then next day 'mechanically' disconnecting it (blank it off) and see what results you get.

Personally I run my doblos with fully operational EGR's.

I did without EGR for a year, but it was hard to gauge the difference as I didnt plug and unplug it to compare. it seemed like there was more power, at first.. but when i replugged it after a year couldnt tell the difference. I only unplugged it after i saw all the gunk the EGR throws into the engine and a major MOT fail for that.

then there was a thread here that the engine is optimized for the EGR so I plugged it back in. Maybe that was your thread. After about 9 months with EGR in the exhaust is smoky on start up due to the gunk build up, so i just clean the air inlet of the gunk before every mot. passes emissions with no problems... also oil change every 6000 miles with EGR on, as the crap going back into engine ends up mucking up the oil faster.

Got the Autel MS300 from Amazon (Vairocana) to read fault codes and it wouldn't link. Contacted company, excellent service and got a MS309 which linked straight away rad the fault code and reset the injector warning lamp, so all fine now. Can recommend the comapany and reader.

Thought it was too easy.....EML came on again, erased once more but came back within the obligatory three starts.
Want to fit a new EHGR now, just to end the saga, problem is which one. Engine is a 1.9 Multijet 105 hp 2008. Cant fin d one to fit, only a JTD 1.9 or the 120 hp version. Any suggestions where l can get a new Pierburg for a good price?
Looked online at Pierburg catalogue, three to choose from.
Car parts 4 less have one at £127, but not sure it's the right one
