....... to offer cruise on the last two years of Xantia hdi production..


after Bosch incorporated cruise into the ecu for what ever reason and Citroen did not bother to offer it on hdis. The option would of been a nice attraction on exclusive's at least and made a nice equipment package..

It works exceptionally well and how I thought. It doesnt use the throttle sesnsor but actually controls internally what the throttle sensor adjusts when you use the throttle.

What I do find when useing it is it appears to feel that the speed increase is more prominent then using the throttle myself. It pulls well on the speed increase.. you can also feel it accellerate to when speed is lost.

it should of been on the options list on the last 2 to 3 years.. If you fancy it its well worth searching out a late X or Y reg car getting the ecu AND body computer and at least one key. This also means you do NOT need the keycard code from either car to install it all.. all you need to do is lexia your RF plip to the replaced body computer.

I'd imagine the cost involved adding it to a model that was about to end production is what stopped it. While you've found it's relatively easy to retrofit, it would have been harder to production quality fit and ensure it worked safely enough for their customers. It's a shame as you say though.

But it was already available on other models of the Xantia!

Ah did not know that, the only one I was aware of for the Xantia was the V6 suction one. For some reason I thought the one people had retrofitted was from a C5. Blame the bug I'm fighting (I'd post a suitable under the weather smilie here but I don't have access to the current live server to sort that out).

Mind you, I don't know if it works the same way.

It was only on the V6 and it is an old-fashioned vacuum one rather than the electronic version on the C5 or like my Berlingo has retrofitted, where it's just a case of plugging the stalk in and activating it in the ECU.

The hdi one is ecu contained and is stalk and brake pedal no connection those are the only connections need making.

This setup is identical to mark one c5s ... as again on them you only need the stalk and switch it on in the engine ecu only. Theres no need to access the bsi on mk.1 c5 hdis to activateit.

It will be the same for any hdi powered thing from 1999 onwards.

Late 2.1 turbodiesel XM's and presumably Xantias have the cruise functionality built in to the injection ECU. It can be retrofitted with the addition of the appropriate switches, relays and wiring - did mine for a Lucas EPIC system.

What counts as a "late" 2.1? ECU Part number? Was the 2.1 ever fitted to S2 Xantias?

Reason for asking is that I saved the ECU from our scrapped 1998 Xantia 2.1 VSX in case anyone wanted it.

Probably post 1995 with the introduction of the Lucas EPIC electronically controlled injection system. My 1996 made XM 2.1TD (RP= 7249) has Lucas ECU label full details as follows:

DCU R04010019A
80708A HOG
Serial no 95045
9627453880
XUDLC01
12V= 05.08.96
OA 12

I'm not familiar with S2 Xantia engine range I'm afraid but Citroen Service does show a 2.1TD option.

EVEN WORSE!!

The same bits were available on the 2.5 XM from its start of production! a good few years before the HDi came along.

Try having the speed set at 60-70 Paul and engage resume at about 30-40.... its pretty dam sharp thats for sure as my bosch 2.5 seems to be able to build boost quicker when using cruise to build backup than the accelerator... i guess its the softer mapping for the TPS where as the ECU and cruise function just sense they are way off where they have been set and dump fuel in as quickly as possible without regard for smoothness.

My 2.0HDi Berlingo (Siemens ECU) also behaves like this. If I've got cruise set to 65 and resume at 40, it's quicker to get back to 60 than with the accelerator and my foot.
