Hi,

I have a 2009 308 HDI 110 with a small amount of oil leaking from under the air doser, type is Delphi 9657485480. I have read the posts about sealing the units before replacing them and wanted to get it off to see where the oil is comming from..
My question is how do you get the hose's off and back on. I tried but they are so tight i thought if i do get them off without snapping something i'd never get them back on.

Thanks

You're right, it is a known issue and can be re-sealed. Best time to remove the hoses are when they're warm and soft.

Had the doser off today and cleaned everything. I was supprised at the amount of oil in the pipes. There were small pools here and there so i removed the pipes from the intercooler expecting to see it full of oil however it was spotless so i'm thinking it's just 40,000 miles of oil vapour building up over 4 years.
Of the 3 mounting pins that the doser sits on, the lower mouting pin was full of oil so it looks like the oil is comming out of the hole under the doser.
Should there be any rubber gaskets or somthing to make a better seal between the doser and mount ?
What is the best stuff to buy to reseal the doser and the doser to it's mount ?

Thanks
Darren

Hi Daren,

It looks like I've got a similar/same issue.

Did you ever figure out what the best method of resealing the doser?

DavidIreland used to say that silicone sealant was used. I'd seen it attempted on two and it was a right bloody mess, so I guess its down to the skill of the applier.

Worryingly that would be me...

At the risk of a thread hijack, would sealing the Doser fix the issue of oil pooling on the top?

Hi

I did my doser used silicone sealer black high temp type very technical this lol

Holes where people had damaged mine used two pence piece put silicone on the coin stuck it on then light coat over the coin to seal

The pipes on mine was only the back one removed it used my finger spread thin layer in pipe popped it back on

The thin layer of oil reduced but does still come from somewhere I used a finger from a latex glove over my electric connection tie wrapped it so stopping ingress of oil

Daft qstn do you know is DavidIreland ok maybe holiday or has he left miss his comments

I never bothered in the end. I removed it and gave everything a good clean and not really had a problem since but this may be down to the low mileage the wife does. Somebody on here said they just remove it every few months and clean it out so thought i'd do the same.
I know it's not a fix but works for the time being.
