1999 996 immobiliser stolen

[neilcerche]

Hi There,

I bought a 1999 996 Cabriolet manual 6 speed that had been stolen trashed and recovered, minus the immobiliser.

The car is a UK import to Australia VIN is WP0ZZZ99ZXS644456.

the ECU BOSCH # 0 261 204 605 / 996.618.601.04

I understand the immobiliser is a M534 model, My question is what is the immobiliser number

I need to get my car running and then start a restoration of this car.

I have spoken to several suppliers in the UK however none of them will send me the correct and matching

immobiliser part number.

They say we don't have the matching part, leaving me back at square one!

Can anyone please provide me with the part number?

Best regards,

Neil

:welcome:

For your VIN you will need: 996 618 260 06 (M534 version)

It will need to be programmed by a Porsche OPC using a PST2 or PIWIS tester.

Thank you so much Loren for your prompt reply.

Can I buy a used one from UK with keys?

Is it possible for this to be programmed more than once?

Will it have to be reprogrammed to my existing ECU?

People tell me I need a full set as being sold as plug and play?

Are there any traps to avoid with this?

Another option I believe is to have the immobiliser bypassed altogether as per the racing fraternity?

Best regards,

Neil

Can I buy a used one from UK with keys?

Yes, but you can likely reprogram it to use your keys (you will need the unique 40 digit ID number for each of your keys).

Is it possible for this to be programmed more than once?

Yes, with the proper codes and keys.

Will it have to be reprogrammed to my existing ECU?

Yes the two work together - so the programming affects both.

People tell me I need a full set as being sold as plug and play?

Are there any traps to avoid with this?

As I said above you need working keys, IPAS codes (available from the OPC), and your cars unique 40 digit ID number for each of your keys.

Another option I believe is to have the immobiliser bypassed altogether as per the racing fraternity?

Porsche race cars use a completely different DME (ECU). Unless you plan to use the car only on the track I do not recommend this.

Sorry Loren, but the Alarm Control Unit can only be programmed with an immobilser code once. However, if you know the immobiliser code for the donor ACU, you could have the DME programmed with that code, so that the units match. You would need the IPAS codes for both vehicles.

[Loren]

Sorry - Richard is correct.

Hi Loren and Richard,

Thanks again for the valuable information.

I have a British supplier who is really trying to help with my dilemma.

Can you read his email and tell me which ECU kit is the right one for my 99 996 Cabriolet manual?

My car is a UK import to Australia VIN is WP0ZZZ99ZXS644456.

the ECU BOSCH # 0 261 204 605 / 996.618.601.04

Dear Neil

I have just removed an ECU set from a 1999 996 today, VIN # WPOZZZ99ZYS602402. Barrel & housing with key included in price. Door handles/locks no problem.

Immobiliser number M534 996.618.260.06

ECU number 996.618.605.00 Bosch 0261 204 790

All units are coded together. ECU number different but it won't give you a problem. *****

Also removed a Boxster ECU set today off a 98 model. Alarm number is 996.618.260.04 M534, ECU number is 996.618.601.04 (Bosch 0261 204 605) VIN # WPOZZZ98ZWS604904.

Quite bizarre how all numbers are very similar between Boxster & 996 models.

Also got a couple of sets of 996 ECU sets from 99/00 models with the following numbers:

Immobiliser 996.618.262.00 & ECU # 996.618.605.00 (Bosch 0261 204 790)

Immobiliser 996.618.260.06 & ECU # 996.618.605.00 (Bosch 0261 204 790)

Thanks for reading this lengthy post, however I really need some expert advise!

Thanking you in advance.

Best regards,

Neil

You will need to make sure that the DME comes from a MY1998 or MY1999 Carrera 2 (which has mechanical throttle) rather than any Carrera 4 (which has eGas), and definitely not from a later Model Year. The Alarm Control Unit and DME can be re-coded with a PST2 or PIWIS to suit the model variants, BUT they cannot be re-programmed for the fuel map, immobiliser code, or for new keys. A Boxster DME will have the wrong fuel map.

The key blades can be swapped from the original car, so you won't need the locks. It is the immobiliser pills and radio remotes from the donor car which you will need to use with the DME and ACU set. Bear in mind that if you don't have the IPAS codes from the donor car, you won't be able to get a new key head programmed to it.

Here are the option codes for your car, btw:

Thanks Richard,

That's it in a nutshell!

Hi All,

It turns out I have been hood winked ! 

After fitting the new immobiliser and had everything encoded the engine will not fully crank as it has been blown up!

I am now up for a rebuilt engine for the car.

 

Can anyone recommend a good source for another engine for a 1999 996 3.4L 6 speed in Australia, or elsewhere for that matter?

I think it prudent to get an engine with the IMS fix applied, am I right on that?

How much is this likely to cost?

Best regards,

Neil
