[220 GSi turbo]

I have a few spare 5AS units that have been salvaged from cars I have dismantled. I think all of the cars were Rover 25s.

Some have the part number YWC001200, others are YWC106240.

Also, some have the letter D in the corner of the label, others G.

Does anybody know if there are any significant differences between the two?

there are basically two main generations of 5AS

the Early type (typically with a large letter "L" on them - and a single grey connector) and a 98MY version, typically with two connectors. The (white) second connector offers extra options, such as flashing indicators, passive ring, and interior light dimmig. You can fit the later type to earlier cars (and add wiring)

In terms of the D's and G's - these are electically similar, and totally interchangable in terms of hardware. However, The software configuration can differ, depending on what cars they were used for, as there were differences.

For instance, The Rover 25 and 45 bonnet catches are wired differently, one is push-to-make, the other is push-to-break. So 5AS needs to be configured to operate. This can be achived using Rover's Testbook, or T4. You just need to reconfigure the "country code" whilst under a vehicle type.


Incidentially - Fobs marked with 3XTA on the backs/circuit boards can only be matched to "L" Spec 5as's. 3XTB/3XTC & 17TN (aka 3XTD) can be programmed to all 5AS's (however, only B and D's ) contain the mechaisms to "excite" the passive coils.

Now - ive only talked about the 433mhz units that are used in the UK and most of the rest of the world - there are some 315MHZ units, used in a few random countries, and these have a different series of large letters - but you need 315Mhz fobs for them, and they are actually illegal to use in the UK

I actually had a look on the Microfiche for the R8. I've hot sets for early and late cars.

The YWC001200 part code never appears anywhere, although YWC100213, 214, 215, 216 etc. do appear. These seem to be related to different countries by way of exclusion from the general "Europe" group, e.g. Switzerland, Netherlands and the UK. I think these are still all 433MHz units.

The YWC106240 part is definitely the standard unit for the R8 series, or at least, it's the one Rimmer Bros now sells for the entire series.

Some part numbers you get on parts, will never show on the EPC - as they were Internal partnumbers used in manufacturing, but differed when the parts were offered in the spares market. I have no idea why....
