Its exactly like those ...................... BUT - you will need a STAR at least with an active and current SCN coding subscription ........................ that’s the mechanism to speak to the OEM ECU and make it do what you want. The problem is to know what you want ito both performance and...

I would not waste time and money with an online map even if one would be available because your motor's condition/requirements etc are not the same as the next guy's - as you have seen and experienced the ECU knows nothing about your intentions after you have modified the stock mechanicals etc -...

I assume you have Torque Pro generating that info you posted in your vids above. The OBD interface is limited in the amount of data it can shift/update a second - I would suggest manually fix the range of all gauges there to allow you to see only the expected operating range per gauge. Then grab...

I would go speak to a dealer with the video evidence in hand - no way they should tell you to go away and that its normal

That imo sounds serious enough to stop driving it immediately and return it under guarantee ................... Sounds heavy and crankshaft rotation speed related ................ big end bearing?

Me? - I would first measure the ability of the fuel rails to maintain pressure after the engine has been switched off .................... any individual injector leaking when it should be closed will generate unwanted diesel liquid in the cylinder that not even a perfect ring set will keep out...

TC maybe x2 ................... or one of the bearings on the output shaft - sounds like soon as a gear set is selected that locks the output shaft to that gear set the noise stops because the bearing is stationary:crazy:

Sure is ............................but then it was said also So if the tc is locked there is no way to have a free revving motor with no power. I suspect we don’t have the full story/picture here Just for the record - I have never ever tried to bump-start a diesel like this...

THAT is strange ..................... and imo should not be able to happen on an auto at all.:confused: I am not claiming to know it all, but with an auto there is nothing driving the dead engine (what you experienced?) to restart it mechanically and electrically that can only happen if you...

Given what has been reported as symptoms and investigative results at this stage, I would be inclined to suspect something power/battery/earth/relay related ................. STAR is not necessarily going to be able to pick up such an issue because eg the ignition power disappearing is...

THIS ..............simply no way does that tally with the rest of the story at all

The current flowing through the charge problem indicator lamp is responsible for exciting the alternator in most cases ....................... if the actual lamp is blown you will have no charge situation. Does the lamp ever light up before you start the engine? ........... if not you may have...

IMO with no coolant loss as stated, all the tests already done and all the parts replaced there can only be one answer ................... My guess is the engine was run on a pure water diet over the years iso a coolant mix that would prevent rust - the result is that block's internal coolant...

THIS! ............... and the converse is also true - iow - you cannot have the water in the expansion tank at any temp above the locale atmospheric boiling point of water if its not pressurized......... implication being with the cap off and the water not seen to be boiling, the water temp is...

Did you run it up to temp with the cap removed initially in order to check level constantly? ............... then I would say your experience is perfectly normal. I would first allow the vehicle to cool completely with the cap off ........... check level and refill to correct level when still...

I guess. I don’t know how sensitive and accurate the in dash temp meter indication is on that particular set-up ............... and also how the ECU has been told to control the cooling fans (STAR). On my W168 I can for example set the slow and fast running cooling fan speed switch points...

What is the real-time info on STAR like for the engine while driving? You can see exactly what the temp (and a horde of other parameters) is doing and whether the ECU is the culprit (activating coolant valve for no reason) or some other mechanical issue is in play. If its over-cooling the...

STAR? This thing needs to get on a STAR and you will know all its miseries

So what - you still have air in the pipes?

Stick it on STAR and monitor real-time data on the coolant/engine system. With the warning off, loosen a water hose a let a small amount of coolant (about the volume of the expansion tank) drain out ............................. does the warning light now get triggered? If yes, refill and see...
