Peugeot 206 1.9 lx jumpy at 2000rpm

Post by Dulson420 »

i recently bought a 2001 206 1.9lx
rough idle (low revs to normal as if im just blipping throttle) when started from cold sometimes will cut out but starts again instantly.. my main issue is that driving along if i keep the revs the same (1800-2200 anything above or below its fine) it gets really jumpy (feels as if its starved of fuel for a second then gets it back).. any help would be grateful

Worth changing the fuel filter if you're not sure when it was last done.

It could be signs of air ingress especially if its cutting out at startup. Favourite poitns for that on this DW8 engine are the fuel filter housing itself (you'll get a new large ovalish o-ring to fit with a filter which may actually cure it if you're lucky!) or the large seal between the filter housing base and the thermostat housing where its sat as it passes fuel over the top of the housing when cold.

The other possibility is the EGR valve is starting to gum up, common on this engine. *if* it runs OK outside this range, temporarily unplug the small vacuum hose from the EGR valve and plug it (do not leave it 'open'!) and see if its any better.

ok will check both in the morning.. would the filter/housing make it act that way in just the certain rev range.. kind of thought that would do it all the way through?

Sorry for the delay. Surprised no one else posted actually. :)

Anyway: It could have odd effects at certain rpm ranges (you'd be surprised) as air ingress can cause some odd effects. Its certainly worth checking as the filter housing assembly on the DW8 is not as strong (in my opinion) as the XUD one, partly the lid design although to be 100% fair to PSA the lid seal on the DW8 one is better than the XUD but the filter contains the seal on the XUD whereas the DW8 one is a separate item supplied with the filter. I've not seen a third party supplied one without the seal either.

Did you have any progress on it ? :)

I'm very much with Andy on this, although I have no direct experience of the DW8 I do have lots of experience of it's elder XUD siblings and on those air ingress can cause just those problems.

check your MAF sensor.

I had this issue. IT was like a brief missfire jump at 1800-2000rpm.

unplugged maf and it went away but car wouldnt rev past 4000rpm in use(not that i normally use that range but with a dw8 its sometimes required)

Swapped it out and the jump at 1800-2000 rpm was gone and it reved up to 4600 again - even if the limited power stops at 4100 :D

Ebay probably best bet. Avoid ones that are a bit um "too cheap" as they won't last very long.

as you plan to replace it you could clean it up (off the car) with some brake cleaner aerosol. Note: Ensure its *fully* dried before fitting it back. Not a lot lose by trying this if its otherwise going in the bin.

New ones from main dealer silly monies unfortunately.

If you replace it do try and get a genuine Siemens/VDO unit, the cheap ones don't last.
I have bought 3 - 2 for the first of my C5s -ruined it with water and grit sucked up when the wheel arch liner disintegrated.

When the current one began to fail I bought a spray can of carburettor cleaner and drowned it in that and a year and a half later it is still fine (fingers crossed)

Don't drop it under any circumstances and don't touch the two fine wires with anything other than the spray.
They are very delicate.

There's a 6 digit number on the underside of the maf body.

Search for that. There is a website that just does sensors. Cant mind it off my head but that's where I got mine. Can't mind the websites name now but the same maf is on many cars and propper pug ones are about twice the price

The dw8 doesn't have a MAF does it? I'm sure theres just the egr at the start of the inlet - https://www.google.co.uk/search?q=1628g ... =560&dpr=4


Edit: apparantly the dw8b does, but my 206 certainly didn't, even though it was a dw8b engine...

In 2004 and 2006 the dw8 sure has a maf. They are consumable and last about 75-80k before dying otherwise I've been fitting mafs to cars that don't have em .

Just found it on servicebox. Odd as my 206 definately didn't have one (and was definately a dw8b!) Which makes me wonder if it had an engine change at some point.

I think it was around 2001 or 2002 they started to appear, as said the engine type "with MAF" is the DW8B although most will still refer to it as a DW8 anyway, not unlike the very last 1.5TUD units are actually TUD5B...
