All Things V6...

How's the collecting of parts for the V6 Activa going David ? Did you get an unlocked manual ECU for the V6 yet ?

If not you might find this a steal:

https://boschelectronicservice.eu/uk/sp ... 0261206119" onclick="window.open(this.href);return false;

It's a brand new manual gearbox version of the ES9J4 engine ECU, un-programmed, for 49 Euros!

It's not unlocked, but is virgin/un-programmed which means you can program it ONCE using a Lexia to match any CPH, (as long as you have the confidential code for the car the CPH came out of) its then permanently matched to that CPH. (Unless you send it to an unlocker of course...)

The advantage of that over just getting it unlocked is that the transponder immobiliser will still work. If I understand things correctly getting the engine ECU fully unlocked as you were planning will disable the immobiliser system thus make the car easier to steal...

I'm a bit disappointed they don't have the Auto version of the ECU or I would have snapped one up at that price

[DHallworth]

Simon, that's an excellent find!

I've just ordered one.

If you're looking for an ECU to test on your car, you'd be welcome to try mine if it's not to bad a job to change the CPH over.

I managed to get a CD drive and disc for the Sat Nav on the C5 on eBay the other day for £45 inc delivery. I plugged it in today and the menu option for the Nav lit up instantly. It's detecting its location now and appears to be correct.

Just need a cheap set of tyres for it now an it's MOT ready. I'd usually put Michelin's on it but I want to see how reliable it's going to be before spending a fortune on tyres.

David.

Thanks for the heads up guys, I've ordered an ECU for my Activa V6 manual.
Even though I'm currently running with a manual V6 ECU, I have the annoyance of the warning buzzer for 30 sec every time I start the engine.

Interesting - so I assume you have an "unlocked" engine ECU that will work regardless of CPH pairing ?

And you're saying it causes the CPH to complain about the immobiliser every time you start the car ? I can see that would be annoying!

£40 for a new genuine ECU its a no brainer really, you can't even buy a set of V6 spark plug leads for that! Let us know how you get on with programming it when you receive it will you ?

I wouldn't mind following you up on that some time in the next month or so David, before the winter sets in ?

I'm still chasing this poor running problem and if anything it has got worse and more intermittent lately, I've ruled out fuelling issues as well as I reasonably can (fuel pump has been swapped with a second hand one a week ago) and I know compressions are good, so I'm pretty certain its ignition misfire related.

I've tried 2 different coil packs, spark plug leads have been replaced twice (the first pair got damaged with that hole if you remember) spark plugs twice etc... yet it still seems to have an intermittent but serious ignition misfire under load.

The next possibility is a faulty "igniter" diving one of the ignition coils - unfortunately on this engine the igniter is an integral part of the ECU!

A temporary ECU swap would allow me to find out once and for all if there is a fault with the ECU, and if nothing else rule it out.

Re the CPH - I've seen addo post that he can get access to and replace a CPH on a S2 after "only" removing the glove box, I'll see if I can get some details from him on that. The other thing is I need to find out if the transponder keys can be reprogrammed on a Xantia - on a C5 they can only be programmed once, but I think on a Xantia they can be re-programmed again. If they can I could program your CPH fitted in my car to respond to my keys so I'm not having to muck around with trying to remove the transponder chips out of the keys...

I'll post a new thread on the forum a bit later seeking advice to see if this is possible as someone else must have already tried it...

Edit: one other thing David - do you have the 4 character confidential code for the donor V6 car ? Without it keys can't be programmed to the CPH...

[Citroening]

Thanks for that link Simon - I passed it onto a mate who has recently converted his Xantia V6 to a manual, so that will come in very handy.

He's just bought one...

Bet you wish you were on commission now...!

Haha, no I'm not bothered, I just wish they had an automatic one for me at that price!

While you can get away with an automatic ECU in a manual with some minor niggles, I very much doubt the manual version of the ECU would work in an automatic if it has the code for communicating with the gearbox disabled or removed...

C5 tyres are quite common now for the alloys David, but getting another set of alloys for the tyres alone is my favourite at the moment

[DHallworth]

Simon,

I don't know if I've got it or not at the moment but will have a look through the book pack and see what's in it. If I don't I'll get it.

One thing I have seen done before is holding one of the donor car keys next to the ignition switch after taking the pcb out of your key to confuse it.

Will,

That's been my trick recently too!

David.

[Mandrake]

Thanks David.

Edit: I've just thought of something, is your donor V6 a S1 or S2 ?

Or was it the other silver V6 that you sent to Ireland that was a S1 ?

[DHallworth]

Donor V6 is an S2 in Mallard Green, the S1 that was dispatched to NI was a Series 1.

[KP]

Works out quite well and if no-one wants the alloys they get weighed in

[DHallworth]

I always feel guilty weighing in perfectly good alloys that may one day come in handy to me or someone else so have accumulated a massive collect of alloys! At least we have a tyre machine so I can get the tyres off them for storage meaning they take up less room!

[KP]

I don't have such storage I already have a set of 19" ff tdv8 runs with pretty new tread MT/R's fitted, a spare xantia wheel and brace set, another set of 20" SSRR wheels coming tomorrow
And another spare mtr in the garage and some other bits!
The SSRR ones are going up for sale straight away to free up some space!

[Mandrake]

Simon, that's an excellent find!

I've just ordered one.

Just for a laugh I looked up Citroens price for the engine ECU, £982 inc VAT!

Yep, they'll sell a lot at that price...
