Peugeot Boxer 4th gear

[engelside]

Had our first proper outing in the MH a couple of weeks ago and I noticed that to get into 4th gear on any type of hill the revs really need to be well above 2000 otherwise it will just not pull. Peugeaot Boxer 2.8 2004 MH.

I'm not sure how much experience you have of driving any larger vehicles such as motorhome.
Your busy finding out that the turbo needs to be singing to make progress, the sheer weight & having to punch a huge hole in the air takes its toll.

6 speed box? Mine pulls like a tractor in 4 5 6th 2.2 57reg

No, it's a 5 speed box.

2.8jtd probably 5 speed.
As ambulancekidd said, keep the turbo singing sweetly.
At that age it might be worth changing the gearbox oil and overfilling as per it might not have been done before, and overfilling as per recommendations. There are threads on here about it if you do a search.
It's a simple DIY job but involves removing the air filter housing.

Like Mr Figaro said.
My 56plate 2.8 jtd pulls well enough. Keep the revs up. 5th is only any good for cruising above 50 on the flat, bit like overdrive if you are old enough to remember that.

2004 2.8 will most likely be the HDI, mine was. Nothing much happens below 2400rpm and nothing much above 3000rpm except it’s handy to hold it at about 3100-3200 to give it an “Italian service” it blows all the crap out ?
If you can see what’s happening half a mile to a mile away give it some stick to get it moving then I change down to fourth about 2200rpm which is just over 50mph or so that will get the revs back in the powerband.

Ours is the Fiat 2.3 130bhp and I've found that changing up has to happen only when the new gear will take at least 2100 rpm, otherwise the turbo quickly goes "off-song" and I'm struggling, especially if I'm on an up incline.

I was always taught to listen to the engine and if it appears to be labouring then change down. On the Fiat the gear spacing is a bit uneven so changes 1/2, 2/3, 3/4 etc all need to be at different rev settings, up to 3000 rpm dependant on conditions. With a bit of practice I no longer notice, just making the change when it needs it.

IMO too many people are "taught" to drive by rote, rather than assessment - not sure that's the right description but I'm sure you know what I mean (long day standing around at NEC talking to people!)

Thanks for all the replies. Will ensure I keep the revs up.

The other thing I noticed was as times when I was accelerating hard in 4th (and in 5th I think). The ECU light came on momentarily. It doesn't stay on and doesn't come on at any other time. Any ideas?

 

[TerryL]

The ECU trying to decide if it should commence the self-cleaning routine I would guess. It needs a good "thrashing" for it to work properly - that's called the "Italian Tuneup". Wouldn't worry too much about it unless it stays on.

Don't think the ECU does that, DBF maybe but the 2.8Jtd might not have one.

 

[TerryL]

Yep, you're right, DBF is what I was thinking of. But any kind of problem there will flash up a warning on the dash. 'Twas just a thought.
