I’m sure the engine will fit , but to make it run , you’ll need all the electronics for the Hdi injection system. Can’t see it being an economical proposition .

Agree - a lot of work. The XUD wasn't a bad engine, what's up with it?

Thanks for reply appreciate 1.9 were good engines but so agricultural it makes the car a completely different vehicle. Depending on the changes required would be willing to spend to do it.
thanks Will

Thanks for reply appreciate all input, I agree it wouldn’t be economical on the face of it but I have had a 2.0 hdi in the exact body and it was I cracking vehicle comfy quiet good on juice. I bought the 1.9 without knowing it was a non Hdi with very low mileage and then when I took it off the trailer realised my presumption to be incorrect the 1.9 were good engines but so agricultural it makes the car a completely different vehicle. Depending on the changes required would be willing to spend to do it.

How much are you willing to spend ? Bear in mind you can buy a complete running car for about £1k or less .

Commensurate with the work required, obviously main dealer prices are out. Would be nice in an ideal world to find a retired enthusiast who would take the job on a set fair price. Or if I could find a clear plan to know exactly what was needed to accomplish would do it myself over time. Also factor in the cost of a donor vehicle. In either instance I would do whatever possible to reduce cost. Thanks doc for your reply

There could be all sorts of problems such as are the engine mounting points the same. All these things can be overcome but it's time and money.

In your situation I would sell the xud and buy the best HDi you can find. The money you would have ploughed into the xud could be better spent getting the HDi up to a high standard, changing any oily bits that are worn and having any panel damage rectified. I think that will give you a better result.

It depends on what you intend to use the car for, and how long you expect to keep it. I personally don't like the idea of mixing major parts on cars - unless something has failed and needs replacing, of course. It could make potential buyers suspicious. As said, better to find a 306 with the original HDi engine.

Hi thanks for your reply, personally I love to see an escort with a red top or a cosworth in there and it looks like it grew there, the custom scene has throws wierd and wonderful and all I want to do here is take an hdi that is commonly found in this model and put it in with the correct components , just knowing how extensive the list of changes is all I wanted help with to do decide. It maybe easier to put a hdi in the same way the custom boys do and use aftermarket bits like ecu etc or even a petrol engine and bike carbs, just love the 306 meridian estate and have a great body to be going on with.

Because they are classic vehicles now! To find one with as low a mileage as my 1.9 which is only 30,000 miles is quite unusual, I had my eye out for about five years to find this one.

But if you fitted your ideal engine, what would be the meaning of your 30K miles ?

Some years ago I picked up a 205 Garros hatchback, now a fairly rare car. There was 147K on the clock, but the owner had bought the shell and fitted a correct 1.4 engine from a CJ with about 95K miles. There was no significant rust anywhere (MoT testers always commented) so I spent £2K on a full repaint, and my SiL's brother now takes it to shows for fun.

But that involved fitting the correct (matching) engine. The HDi may need things like wiring looms, never mind whether the engine mounts are compatible.

Hi the relationship to being 30,000 miles is the vehicle itself has also only travelled that mileage it is rust free interior cleaned up like new and even though it’s an xud the trim is a meridian bodywork was a bit bashed but fitted correct colour door and wing painted the roof rails and it looks really nice with only a couple of dings here and there which would fairly easily be addressed it’s on steel wheels which I prefer with brand new tyres. Just drives like a tractor and having had a 2.0 hdi for 20 years I really feel the difference

I still find it strange that a car of this age has an XUD fitted, so long after the HDI became standard. Do you know the full history of this car, or is it already a hybrid ?

It might be interesting to know the VIN of the car, which would give its approximate age and the identity of the engine it was built with ?

Hi the car before me was new to the father as a motability car then passed to the daughter who I purchased from. The trim level is close to meridian although it’s not a meridian on the logbook. To be honest I have never looked at the vin but you have piqued my interest hope it’s not a ringer ??
Since I have owned have asked questions as I wasn’t expecting it to be a non hdi on that year car, and few have said it’s been sold after the run ended and registered late, not sure but that seems to be the opinion, but will be checking the logbook against the car, it has been mot’d since I owned but that doesn’t mean they checked the vin cheers Will

When you take your car for an mot , the registration number is checked against the vin number produced on the certificate and the car chassis. If there’s a mismatch, then the test can’t proceed.

From what we have been told, I would expect the car's reg to match its VIN as that is essentially part of the bodywork (just as on my 205 Garros) but I can't help wondering why there is a XUD engine in it for its age, unless someone changed the engine at some point. If that has been done the VIN (characters 7,8,9) will show the original engine code. Gibbo_Wirral may know those by heart, but if not, the 306 handbook is where to look - if the car still has one. If that has happened it should be possible to put an HDi back in !

Are you sure the engine is an xud and not a dw8 ? the vin will have wjx wjy or wjz in it if it is.

Fine - but if the engine has been changed it's extremely unlikely that the VIN will have been altered to match !

The VIN number can't be changed, not legally anyway.

Late 306's were available with the dw8 engine, the vin should tell you what engine was fitted at manufacture, is the op sure it's an xud?

Just dug out the part-ex docs from 2008, when I traded my 306 Meridian HDi against my present car. The 306 was a late-T plate registered August 1999, VIN was VF3 7ARHYE 32820624. The HYE is the engine code ; its engine number was DYAL 4043663, but I doubt that will tell you much. If you compare the 8-digit vehicle number in my VIN that may indicate when your car left the factory.

EDIT - just realised that the OP hasn't told us the age of his car here, but in his earlier post he said it was 2002. Should definitely have come with an HDI engine IMHO ?

Not quite. The engine code is RHY .

My apologies if Peugeot changed the format of the VIN from the one they used for the 205 :-). On that basis, what is the meaning of the 'E' ?

Going to google and see if I can find it, thanks to everyone trying to help me cheers Will

From the info on the vin number , your engine type is a WJY . Used in many Peugeots and Citroen models.

Have been trying to find on the net what a wjy engine is but no luck so far
Am I to take it that it’s not an xud engine ? It looks to be a dw8 engine looking at a recent post from another member

Thanks for that I think it may be as you suggest, as I’d says wjy need to have a look at what a dw8 engine is and compare what’s under the bonnet as a one family owned 32,000 not expecting it to have been changed
Peugeot 306 1.9 xud - 1.9 xud to Hdi - Andrew Irvine

DW8 is an updated XUD9, indirect mechanical injection and no turbo I believe, there's a wikipedia page on it. Used to mostly see it in small peugeot citroen vans.

Thanks for all your help will have a look at that wiki page cheers
Peugeot 306 1.9 xud - 1.9 xud to Hdi - William Beer
Spot on thanks Andrew it’s a DW8-b wjy engine cheers Will now be able to search internet for info??

All this time have been looking for info on the wrong engine I actually have a dw8-b wjy engine thanks to Andy for clarification regards Will
