Afternoon all.
The car had a service today and I've had an advisory on the air doser. (oil leaking from it) They want £291.06 to sort it.
Found one on ebay for £65.00 Not necessarily the one i'm going to buy but it give me options.eBay - The UK's Online Marketplace

Anyway my question is, is it easy to fit?
It looks fairly straight forward but any help/info/comments greatly appreciated.

doesnt look too problematic
That's what i'm hoping for.:lol:
Found one on eurocarparts after much faffing about for £124.80 no picture though.....hope it's the right part. They've got a branch near me, so might have a trip down there.

Also after a bit of research, i've read that oil can pass through the turbo seals and cause this problem.

Always get a little oil pass through... intercooler always has a film of oil inside, so makes sense that the air doser will too :nod:

There is info on this problem. The dosier valve is to be removed and sealed around its edge. This cures the problem.
The valve is NOT to be replaced. :nono:
The new one will probably leak also! :nod:

That's what I'd read/heard.
I have no objection to buying a new part, as long as it cures the problem, however if this could happen again with a new part then I'd rather save myself the money.
It's not like oil is pouring out everywhere, infact it's not used any oil in the last 15 months.

The guy at peugeot told me it could be sealed but it doesn't always work and I'd be better off with a new part.
Do you have the info so I could print out and show them?

If there is info on it, the guy at your Peugeot has it, but chosen not to follow it 100% :nod:

It does work.
Was this coming from the guy that was selling a new part for x price?
I rest my case.

Cannot give you the info. Trust me its there.

Yes it was. I'll take a trip back to the garage tomorrow and have a word.

Thanks for the replies and info everyone.:thumb:

davidireland, do you have any idea how much this work might cost me?

I don't know, half hour to an hours labour plus black sealer?
Dependent on dealer.

I found an independent garage who specialize in peugeot/citroens.

Had a quote from them to have the air doser sealed.

£50 plus vat.

Good result I think.:D

I just thought I'd add to this thread, seeing as how I've just seen DGH!

I went to look at a 307 1.6 110 with the same engine in Preston last month, and that had an air doser problem - oil was present on top of the alternator, oil cooler and pipes.

The garage had replaced the doser (£190 from Peugeot).

The old doser had been attempted to be repaired and re-sealed but it hadn't worked.

I don't think this is a common issue (after all its the same engine as the 407), it took a bit of searching to find a small handful of reports, and most of them relate to damage to other components (starter motor and alternator) due to oil ingress.

A post on a generic TDI forum from a 406 owner with the same problem was told its a common fault on remapped 406's because of higher intake pressures.

Also, if you wanted to save a bit of money by taking it off in preparation to be sealed then it's actually a really simple job, 3 long 10mm bolts, and then the jubilee clips for the pipes, and that is it!

From memory there is a bolt on the top, side and front, it's basically mated to an aluminum bracket which is bolted to the head.

An update

Evening all.
Just thought I'd give a little update to my air doser problem.

A new air doser bought and fitted, and all seems to be well.......just jinxed myself there haven't I. :lol:

Anyway, the old one didn't look too healthy. :nono:

Why didn't you just seal it. Sealing around the outer edge is an official Peugeot repair of the leak!

David, I hope you don't think I was disregarding your input, it was much appreciated, however my local peugeot garage and an independent I had found were not interested in sealing the doser.
Also with the doser being broken on the bottom (see picture) I thought I'd be better off with a new part.
I hope I can still call on your advice in the future.
