Hi I believe I need to change my TV Hybrid unit in my 2009 L322 because I’m getting the temperature error which has been covered on this forum.
The one that is on it at the minute says TCR TV hybrid with the code 7H42 19C063-AB.
Replacements that I have seen don’t say ‘TCR’ (I have seen some that have ‘PAG’ on them) and have a different code for the first 2 and last 2 characters. The ‘42 19C063‘ is the same however. For eg AH42 19C063-??/ UH42 19C063-??

The question is what, if any, are the differences between them and will they fit and function in my truck?

Thanks 2009 FFRR 3.6 TDV8

Update

After searching through the the internet I found a module that was the same as mine which had been taken off a 2008 disco 3 the only difference was the end two characters were AA as opposed to the AB on mine. I have plugged it in and it seems to have done the trick (touch wood)

Now just need to find out how to take the old one out and insert the new one. 2009 FFRR 3.6 TDV8

Yes, I ended up with a unit off an RRS/Disco as well, I'd have to check the exact code, but the final letter was slightly different I think. As long as you don't get one of the Japanese/US market ones, which have a different preceding code, you should be fine.

Very easy to remove and replace from the left hand rear cubby in the boot, but not much space for hands to work in to extract/replace the bolts.

If it's the same as my RRS/Disco unit, then you might find that the mounting holes are in the top of the tuner, whilst the L322 uses side mounting holes. In my unit, the holes were pyhsically there, just not tapped out to accept the screws, so I just used the appropriate size tap (sadly I didn't write it down in my thread what it was!), and then it mounted as per the original. For a few days I ran around with it just Duck taped down, to prove it really did work before tapping it out, and that was fine too!
