The Rover 75 and Freelander (ok, not Rover at that point) diesels were (yet again) detuned BMW lumps..

Freelander used L series and TD5 (Rover 2.5TD, a variation of L series with 5 cylinders and different management system, and planned to be a series of different sized diesels), pretty certain the 75 used the same L series (2.0D) and TD5 (2.5D), but will stand corrected on that.

Certainly, the only BMW engine to go in Rover/LR was the 2.5TD 6cyl that was fitted to the Range Rover 2.5D only

rover 20t2n & 20t2r are both bmw designs which share many design and components as the 6 cylinder which has many codes but is known to us oofers as u25td, x25td, or our euro late owners y25td
the ecu under the bonnet is in same alu casing as miggy too

[JamesV6CDX]

Dean - how do you tension the belt, on the 406 TD?

[JamesV6CDX]

1.9 Is Bomb Proof there are issues with the alternator mounts smashing to pieces !

2.1 is an older citroen engine that can be traced back along time!

HDi Engines are even better despite what people say all the taxis in hereford are HDi 406's

TB do you mean the Rover 2.0 TD engine fitted as fitted in the 620D??? as thats a BL engine

I looked at the HDi - but, they seem to eat up expensive FAP filters (£500 a pop) and requre the device filling at £19 / litre. I've also read of numerous engine management issues on them - which is why for the sake of 5mpg less, I thought the mechanical 1.9TD might be a better bet....

20t2 is the L series designation isn't it?  L series is most definatively a Rover design, a development of the earlier Rover 2.0 diesels fitted to Montego crap. L series is not BMW (nor is TD5), though does use similar Bosch DDE ECU as BMW's 6 cylinder design.  TD5 uses a very different Lucas ECU.

tension pulley on like a cam and tighten but may not be so true as it is over 7years since did one and slept a good few hours since
better than on my embarssingly owned tdi escort which i managed to be a tooth out on fuel pump but managed to put right on pump timing without putting belt right

L series (may be wrong) i am led to believe was based on "perkins" design which fitted the montego and maestrovan

L series is a direct injection develoopment of the montego diesel, which I think you are correct was perkins. Its an exclusive rover design, shared only with Rover's running mate, Honda, before BMW screwed up that relationship.

I am pretty certain the 20t2 engine designation refers to the L series  :-/

only drove the rover tractor since 7december and not even serviced it yet but all seems similar design(minus a couple of pots)to 2.5tdmiggy.
ignition timing (miggycode81) is on injector1 on rover but on injector4 on miggy but all data seems to go to and from ecu in same ideas

Thats because it uses the same basic ECU - Bosch DDE - and thus the same array of sensors. Other than the fact that both engines use the same 3rd party supplier for the engine management, the engines are entirely unrelated.

Later Rover 2/4/600's used the L series which is the Perkins based ex-O series engine.
Rover 75 used the M47 BMW engine (confirmed by a BMW Tech who looked at a 75 engine bay).
The Freelander diesel (from 2000 onwards; Td4) was also the BMW unit as when MGR/Powertrain went bump, all Landrover could sell was Diesel Freelanders as they couldn't get any petrol engines.

James, IIRCC you want a couple of M4(?) bolts to lock pump and crank... Easy job though!

Good stuff. Thanks mate
