Citroen XM Forum

Just phoned Citroen UK and they gave me FV600001991 for the engine number. She didn't inspire much confidence, computer says...!

Here's hoping for a simple H Reg No from DVLA.

That seems a bit of a coincidence Marc if the year of the car is also 1991! The number suggested by John sounds more likely. Just out of interest what is the car RP number (on front left hand side door pillar) that will determine the day the car left the factory. The VIN number suggests that your car is later than mine and my RP is 5072. With regards, Matthew T.

Apply with the number given from Citroen.
Make a written record of that conversation and keep it with the copy of the application and the V5 when it comes.
If at a later date an actual check proves a different number then just apply to get the V5 amended as an engine change.

How did you work that out?

I wondered that myself Will but did not dare to ask assuming I had missed something!! With regards, Matthew T.

Marcs RP number is 5177 which gives 11 January 1991.

My logic came from finding out that all 1991 V6-24v cars were numbered in the same VIN sequence.
I had previously assumed that RHD cars would have had a separate VIN block.
Took the difference between the VIN's and added it to the known engine number.
Hence the need to prove the logic with a third set of data.

This is possible, it's beginning to make sense.

John said the engine number is in the order of

Note there are nine digits after the FV.

I have log books for three cars and note that the early car engine number has no prefix, so suspect Matthews is similar.
In build date order mine are
000660
DA49060042
DA43000154

I suspect he newer car had an older style engine as it has no EGR fitted, hence the lower engine type number. (DA43)

I suspect the prefix for the v6 is FV starting at 1 and running upwards, so a newer engine can have an apparently lower number.

Hopping in at a very late stage; well done on the MOT pass Marc.

I know I'm hellish late with this...

Great news on the MOT pass! It's always a big sigh of relief to get that good news.

If it helps to prove the theory, here's the details of the 3 24v's I've got:

Chassis No: AL0859, Engine No: 002832 (1991, J Reg)
Chassis No: AL1063, Engine No: 003388 (1991, J Reg)
Chassis No: AL0805, Engine No: 002809 (1992, K Reg)

Interesting to note the 1992 K plate has a lower engine number then the two 1991 J plates... I can't however prove it's never been changed either I guess.
