I thought all the sumps were replaced years ago... sounds like a Defender that has not been near a dealer for ages and they probably done all the outstanding service bulletins which of course includes the ECU re-map??

vaucluse, all i can suggest is that you get stroppy and take it up with the Dealer Principal. That's your best bet when arguing that your car was fine when it went in and now knocks like a bag of spanners. Then perhaps a complaint to LR in Solihull.

Is there any way of checking what downloads if any were done and when etc..?

If you have the right tool then you can read the software version installed on the ECU, though there are numerous software builds for the defender. The software version will look something like this: 7H12-12K532-AAA which would have been installed on the very first batch of Pumas off the production line. To see what updated software version you have you need to check what the last letter is, A is the original build and the latest version ends in E. So the latest up to date LR software version will then be 7H12-12K532-AAE. Below is an out of date list of software builds for the Puma and you will see that they all end in D, which was the last update when that list was generated. When LR release the next update the software version will end in F and that is how you can tell how many times the ECU has been updated, as it can only be updated 14 times before needing replaced or reflashed back to zero count.

The below pic is of my Puma and you can see the software version, you may also notice that it ends in B as this software version allows my Puma to run like a little sweetie and I do not want LR to possibly it up by installing the later version of software and end up with it running like a bag of spanners.

If you have a fault code reader check for injector imbalance DTC's which would be a good indication that you need to redo pilot correction learn. The process itself is pretty straight forward if you have the relevant diagnostic tool. Also if they did upgrade the software they will have definitely needed to redo pilot correction learn, it is possible that either this was not done, or done incorrectly.

Mark - Try a tank of fuel conditioner which will probably help with the noise.

Re Hawkeye, this is based on the T4 Mobile system introduced in dealerships around the late 90's. The idea was that a busy workshop will need to spread its diagnostic resources, so rather than have to spend 5-10k on a second T4 system, the techs could use the limited resources offered by the much cheaper T4 mobile system. From what I understand, Omitec (who put the Rover/LR Testbook system together) decided to release this again on the open market as a DIY solution. I've not used it at all, but I do know T4 will not calculate fuel efficiency etc, like many of the other systems, so I guess Hawkeye won't. Also don't forget that T4 does not operate past the Td5 engines on Defender or Discovery, so the chances are that the software running on the Hawkeye for the Tdci engines is probably related to the Omitec UCM which has a limited coverage (unfortunately because it is very good otherwise).

Moving to the latest question, SDD (which used to be called IDS or IDS Legacy) will make a record of any diagnostic work done which is then stored on the SDD system as a 'Session', so it is possible to put the fault codes back onto a vehicle if you have already deleted them, and it also records what happened in previous sessions, all based on the unique VIN of a vehicle. When looking into a problem, SDD will show mileage and time of when the code was flagged. Now what I can't say is if SDD can look deeper into a vehicle and see what was done in relation to a software download onto the vehicle. I know it does throw a strop if another diagnostic system has been used as very often it ends up spending time reading and correcting software it considers erronious.

Regarding the mapping, what I tend to do is read the map file from a vehicle and send it to Gary at Alive who more often than not can trace the origins (and often the faults ) of the tune.

If they replaced the sump do you think it is possible that the mechanic started the car without putting oil in it? Are you sure it is a diesel knock?

How long could the puma run on no oil before siezing?

It's surprising how long a motor will run with just oil residues in it just ticking over - hours
