R75 & MG ZT/ZT-T Diesel Identification Codes - MG-Rover.org Forums

Rincewind · 20-01-2006, 11:31

As some people appear to be interested and I've been requested to do it, I've put together a document that lists all of the variant and version codes used for the Rover 75 and MG ZT/ZT-T diesel engines. Sorry it's taken a bit of time to get sorted and on the forum.

In the document you will find the codes used to determine what engine tune you have in your vehicle (either 116 or 131ps). One document looks after Rover 75 Saloon and Tourer and the other one looks after MG ZT & ZT-T (sorry that they are not very pretty to look at. If someone wants to make them look pretty, please carry on, just let me know what you've done before you "publish it" so to speak).

You need to look at your V5 document and at the top there should be 2 lines, one saying Variant and the other saying Version. Match these codes to the document and you should find out if you have what you think you have!

Any problems, drop me a line. I think that I have captured all of the codes, but having gone through documents from 1998, there are quite a few and I may have got a bit number blind!

Hopefully this will help you identifiy what your car was at the time it left MGR at Longbridge and if it's been "fiddled" with since. I hope that it is of use to you all.

Rincewind thanks for doing this, had a bit of a worry with my ZTT 135 CDTi, the V5 checkes out as 03C which is the 116 version, however after checking my VIN plate and seeing the white XPower sticker, it appears that the XPower upgrade was fitted at some point in the car's life.

Not a problem, that's why I did it so people could check their cars. At least yours has been done properly and maked up correctly.

Hmmm ... how else can I tell what version I have, as our documentation in Ireland is different?

Give me as much information as you can about the car. do you have any kind of V5 information that you could give me?

Grendel · 24-01-2006, 18:22

Anything similar for 160/190 ZTs Rince?

I'll have a crack, that could take even longer to sort out, but yes, I should be able to sort something out for the petrol version cars. It's getting a bit busy again at work, so it make take a little longer to sort than it did with the squiesel versions (and that was a while!) but I'll try and sort it out for everyone.

rincewind thanks for the variant codes. i checked my car out last night but there was no variant code on the log book! there were other details missing as well. it is the new type of log book.
i also checked out the wifes and that was a 116.(all ok there)
could anyone check there taxation class and let me know what a diesel saloon should be? we have 2 identical cars with 2 taxation classes!!
cheers ... john

johnnysvoid · 07-02-2006, 09:13

with ref to the above request about the taxation class - it is because the 1st car was registered in 2000 and the wifes was registered in 2001. something to do with emissions testing. two identical cars but two levels of road tax!

Yep a crazy situation my 75 CDT costs less to tax than my slightly older Picasso even though the Picasso produces less emisions Silly or what!

Rincewind · 07-02-2006, 18:03

In a nutshell, yes it's all to do with emissions levels and what not and also the introduction of the different taxation rules by the govt!. All very confusing and far too lengthy to go into here as the emissions directive when printed out is 1" thick and depending on when it was registered, different taxation classes were banded about.

Sorry about the delay - all I have is the chassis number, believe it or not. Can't see anything on the registration certs that give this level of detail. Is there anything on the car itself that might help here?

Dragging up an ancient post was trying to find out if my ZT was a 131 or a 116. No x power sticker on the car and V5 says its a 03C version which makes it a 116, however if the dealer did the bhp upgrade would this not show up on the V5? The dealer has closed and is now a caravan dealer so cant check with their records. Any other way of telling, except for a rolling road?

No, if the dealer has upgraded the car retrospectively, it wouldn't show up anywhere, or on the V5.

I am led to believe that dealers were supposed to add the X Power sticker if they did the upgrade, but I would imagine that some forgot.

MARTIN1973 · 26-01-2007, 14:12

When i can find a rolling road fairly local I may put the car on just to see what the true remap figures are. Knowing main stealers the sticker was probably £15 plus £33.98 + VAT in labour for application

it will show up on testbook as to whether the tune is 116 or 131. I checked mine (had xpower upgrade after delivery... wanted to know it was still there!)
Tune is component of the ZCS coding.

Isis · 29-01-2007, 15:17

Would testbook show a remap like Upsolute?

I was thinking more paper based and visual vehicle checks. Thanks for the info pondweed about testbook though, its good to have these things confirmed
