My obd is saying my jaguar xk is a 2006 to 2009 model but is registered as 2011

It's not unknown for cars to hang around in dealers before being sold, often they will run a demonstrator car on trade plates for extended periods and/or the car may have originally gone to say Penzance, not sold after 6 months so was transferred to Dundee and sat there for 6 months until a dealer in London said they had a customer. Said customer would then back out of the deal after the dealer transferred the car to them so it would sit another 6 months until finding its first owner.

Tha's 18 months after first build so could eaily be a 2009 car registered in 2011 if you see what i mean.

Hi

Pm your reg, I can look on Jaguar sdd and it should tell me when it was made

if its a 4.2 v8, the engine number is the time and date it was made, that will give you a good idea

cheers

Joe
