Anyone know if it is possible to retrofit CC to a 987. I am changing from a 986 to a 987 and am having difficulty finding one with CC.

My local OPC says it is not possible, but I have seen the mod for the 986, so I thought it must be possible for a 987, especially as it is an optional extra from new. Part list required would be appreciated.

Thanks in advance, Brian.

Hi

There are no problems for European 987 and 997 to retrofit cruise control. All you need are: 1 stalk, 1 cover ( under ) steering column, 1 short electric cable ( only for the very first models ) and 2 screws for the fixation of the stalk.

Programming with PIWIS tester is needed, max. labour time 0 h 30. Piece of cake.

Thank. I am looking for a 2005 987.

Do you know if there is a step-by-step guide / Technical bulletin available for this?

My local UK OPC says it cant be done. I just want to be sure of what is involved (ie where to make connections etc) before tackling the project.

You mention the short electric cable for early models, where does the connect, and what about later models?

Thanks.

A guide is not really necessary, it's a plug and play system. Take off the steering wheel and the cover under the steering column, fit the stalk in place with the two screws - fit the new cover and the steering wheel - program DME and GATEWAY.

The short cable is only for the early models (LHD). Your OPC can find all information's in PPN or TB

Wow. This sounds too easy!!

So are you saying that the new stalk actually plugs into a socket in the steering column to make the plug and play connection?

Thanks.

How difficult is it to remove the steering wheel and what happens to the air bag?

I contacted my local OPC who say they can supply the parts for around GBP150, but they have confirmed via Porsche HQ that they are unable to code the CC into the onboard computer. How absurd!! :cursing:

Any ideas?

You need to find an independent specialist with a PIWIS and I doubt if there are many around at the moment. The only one I know who profess "We are the only UK Independant who can offer full diagnostic checks on all Porsche models inc 997" are Ninemeister. Whether they have the PIWIS or not I don't know, but it would be worth a phone call. Maybe they just have the Durametric, as this would make the same claim possible. There is also another computer from Autologic, but I don't know if development of the Porsche software is complete yet. I do know that Autologic have a PIWIS which they use for development. They are based in Whitney, Oxon. It might be worth a call to them too. Speak to Jerome.

I'd like to ask if anyone has tried this recently with success?

I went out and bought the required parts (the steering column lower cowl/cover, the fixings and the cruise control switch (part number 997.613.261.00) but when I got to fit the new (extra) crise control switch I found that there is a socket moulded into the rear face of it which looks as though it's meant to take a three pin connector, and there's no obvious loose flying lead with an unused connector to plug in!

My car is an 07MY Cayman but the switch I sourced is a bit older - looks to be July 2004 from the manufactur's sticker, so I'm wondering if this is the problem. RFM said that the 'short cable is only needed for the early models (LHD)' but I'm not sure whether, if I get the cable. where to connect it to, or conversely, if my crusise control switch needs to be replaced with a newer one I still can't see that ther eis anything for it to 'plug and play' into!

Any thoughts or experience?

Regards

James

From what i've read and seen, the steering column stalks / switch also includes a control unit. The control unit is coded via the PWIS tester to enable the cruise and other add on functions. I have an early 987s which I intend to retro fit the multi function wheel controls to. From the PET parts catalogue it suggests there is some form of CAN cable that plugs from the cruise control stalk module into the rear of the wiper stalk above it. There is only one part number listed for the control module , suggesting its common to both options. Its possible that on later cars the flying lead has been replaced and the cruise module just clips directly onto the main stalk assembly with no need for an external cable.

I have just retro fitted cruise control stalk part no 997.613.261.00.01C, but you need the wiring harness to connect the two stalks together, cruise to wiper, wiring harness part no 997.662.674.00

I have just done this retro fit today and will have it coded by my local OPC $tealer (UK) next Tue.

After reconnecting the battery, turn key (still in situ during retro fit) from Pos 0 to Pos 1 and wait 30 seconds to allow Throttle Learning, DO NOT press any foot pedals

Windows up and down to reset onetouch

Reset Clock

Steering calibration. Drive forward with steering at 20 degree angle.

PSM Failure illuminated on dash, take a short drive to clear.

Get coded at OPC $tealer which should take no more than 30 mins labour

Look in the 997 DIY section, my cruise control retrofit notes are in there. If you can't find them PM and I will email you.

Cost is about £150 if you have the standard plastic trim, another extra £175 if you have the leather steering wheel trim.

If you are UK based Porsche are now charging a premium for the cruise control switch, should be about £40 but they are now adding a surcharge of about £175 meaning the £150 job is about £325 which is more or less what it costs for the retrokit. I.e. They are trying to stop you buying just the parts as it is cheaper. Try and source the cruise control stalk from the US if you can, its cheaper!

Any queries just PM me.

Cheers.

How much did it cost you all up? I'm looking at Boxsters right now and not many seem to have cruise (essential for those average speed zones on the motorway). I'd like to know how much to allow for a retrofit.

Thanks.
