[SOLVED] 2.0HDi cruise control

[benoliver999]

I was having a quick look at the user manual and notice a passing mention of cruise control. Then I looked it up here and found dozens of threads. I'm just trying to get my ducks in a row to see if it's possible to retrofit it.

My understanding from reading here is:

• Check there's a socket for it on the steering column opposite the radio stalk
  
• Check for brake & clutch switches
  
• Check if the throttle pedal supports a limiter?
  
• Get a stalk and fit it
  
• Enable CC in the ECU & BSI
  

My questions are:

• Where do I find the code for the throttle pedal about the limiter?
  
• What is the stalk part number? Does that depend on whether I need a limiter?
  
• Where do I look to see if brake a clutch switches are fitted?
  

The car is a 2003 2.0HDi M59

I've fitted CC to 2 M59's both of them had the correct steering column & also had the clutch & brake switches so chances are that yours will have, although as it's 2003 maybe not.

The steering column is an easy enough check, just get the covers off and you should see where the CC stalk goes, there will probably be a cover over the socket.

Not sure if the limiter is possible on the M59 2.0, others will know.

In any case you'll need access to Lexia for the programming of the BSI & ECU. Lexia will also be able to tell you via the actuator tests if the switches are present & working & if the stalk is working.

I think just about any genuine used stalk will work, don't be tempted to buy a Chinese copy. I've had a quick look on eBay, the first few stalks I looked at are CC & Limter stalks. From earlier threads on here, the limiter stalk will work for just CC.

The column almost certainly will have a socket for the CC stalk, hidden behind the shroud so you'd have to cut a hole out of it.

The stalk just plugs in - but get a genuine one from a breaker or reputable retailer, NOT one of the cheap new Chinese clones flooding the market - they don't work.

You will probably already have the clutch switch and one of the two brake switches needed. The one you have is a push to make and operates the brake lights. As I understand it, a second brake switch may or may not be needed, a push to break to tell the BSI to cut the CC as soon as you use the brake pedal. Not sure on this point.

You will need Diagbox & Lexia to program it in.

Your gas pedal must be cable-controlled, i.e. it must have a wire cable going through the bulkhead. If it only has electric wires instead, you're out of luck.

If it does have a cable into the engine bay, then there's a further two possibilities. Either the cable goes all the way to your carb, in which case you can have CC with limiter; or it goes to a throttle position sensor on a bracket in the offside of the engine bay, and from there you have some electric wires going further. In this case you can have CC but not limiter. I have posted pics of that bracket in my car in earlier posts.

The CC stalks come with or without limiter switches; some say that you have to have the correct one or it will not work properly.

What sort of instrument cluster do you have? It is probable that you have the standard M59 one which is no good for CC. This has a small LCD at top centre which displays miles and trip miles. What you need is a different cluster with a larger LCD taking up the right hand dial position (water temp in the standard cluster). These are almost impossible to find - see posts on the subject by saskak, who lists part numbers for them.

If you do swap clusters, make sure the replacement has a lower mileage on it than your car has clocked up - otherwise your car will adopt the higher reading from the replacement cluster and there's nothing you can do about it. So make sure the cluster seller specifies its displayed mileage. If it is lower than your car, then the car will update the cluster with your actual mileage, and that is also irreversible.

I was lucky enough to get one of these clusters from one of our regular posters, and to have it serviced by another one, with the hope of adding CC to my 53 reg 1.4i. But I have been ill since before Xmas so haven't been up to doing it yet. I hope to have a bash in a few months' time.

One thing I am hoping to attempt when I do get round to this, is to read the signals which update the CC data shown on its LCD, and then to make up a small 'add-on' display which, if it works, would allow M59s with standard clusters to have CC. But again, this project will be a long way off.

Thanks both, this is precisely all the stuff I've been try to collate from the forums. It's tricky though because you can be reading something then realise it's for a B9.

Do you reckon the CC with work without the instrument cluster? EDIT: Looks like it will, but the instruments won't!

[Sol]

Hard to say, on the B9 it's usually straightforward but the M59 as Rasputin says, can be tricky. If the instrument cluster is the wrong type, the gauges all drop dead while CC is engaged I believe from others who have tried on the M59. @saskak has gotten further than most I think and needed a euro cluster which came in KMH and was very hard to find.

Likely he will be along to confirm.

[benoliver999]

@saskak 's thread is really interesting , thanks for the pointer

Looks like you can get a euro cluster and reprogram the epprom - involved but not impossible!

Unless there's something particularly odd about a 2003 setup, the 2.0 should not be a problem so far as the instrument cluster is concerned, there was no need to change anything on my '05 2.0 HDi. It was my first dabble with Lexia, done with help from someone on the Peugeot forum.
The problem is with the 1.6HDi engine which has a different ECU.

I've attached some notes that I made at the time, one thing that's missing is the BSI programming code which is 03114

Interesting, in that case I'll give it a go without the instrument cluster and see how I get on.

Seems that I did a bit of reading on the subject & made notes of the links I visited..

[saskak]

AFAIK, the 2.0HDi should be straight forward without the need to upgrade the instrument cluster. Make sure that the CC controls (up/down/on/off) are recognised in Lexia, I think under the actuator tests, i.e. you ca see them changing values accordingly. See if it works and if it does not let us know.
