Hi McGregor, thanks for the offer much appreciated, what i was more interested in was what the logs look like on start up,I'm not a expert with VCD'S myself but if u go into measuring blocks and add blocks to the log as car is started should then store that if i'm correct, i'm pretty sure we have eliminated it to ECU as everything else has been checked and ok.and some of the values showing in measuring blocks don't correspond to values VCDS shows when waving mouse over them and the values VCDS recommends.If u jump on Ross tech site or Google it will show u how to log a scan to the appropriate engine blocks. cheers thnx . Ron

Hi yep checked Battery replaced with new extreme and yes has always had Diesel additive and injector cleaner run thru it, most likely cause is ECU as run out of things to systematically check and some odd values shown up in ECU on VCDS scan, about to replace ECU with second handy and have it reprogrammed to this vin etc $150 + postage for reprogram + 330 second hand ecu, can buy reprogram equipment for bout 80 online but still have to swap EPROMS as that is where they store vin mobiliser info etc as I understand it. modern technology great while it's going bull **** when it isn't LOL Having a rest from it at the moment and catching up on other jobs I need done.

Oh well atleast you tried and got to learn a few new tricks. Good luck with it. Which battery did you get btw I am up for a change soon, thinking of Varta E44.

Ok so ive been trying to find a nice example of the slow to start and then crappy running and low and behold the damn thing is working. Interestingly enough though ive noticed that the glow plug light is staying on cor longer, normally on a cold morning it just flashes by quickly but last two days its been going for 2-3secs. So no example for you yet sorry.
In my case im wondering how my temp sensors are going cos thats just weird.

Hi I put a Exide XDIN66MF with 42 month warranty,and rolls over easier now after doing timing reset and injector reset with dial gauge.

Hi Mcgregor, glow plugs in these run for 2 secs then reduce in voltage, even though they run at 7 volts that first pre glow of 2 secs is at 11 volts then they monitor each cycle and adjust voltage accordingly thru a relay located right way down well hidden under battery box, so in order to get to relay u remove battery and intake air filter hose and access it from engine side, $ 150 for that relay. Ya glow plugs get m of EBAY England 4 NGK 's CZ 304's if memory serves me correctly $102 AUD delivered in 17 days as I saw one ya other posts re glow plugs, yes they original NGK, ceramic tips are used in them, but people here in Aus want $350 for same items I think they call them thieves. Or they must think we are stupid and do not know about the global world. Computer coming tomoz as have had a break from car for past month or more and have pretty much eliminated everything bar computer. So I suspect that is what it has been all along, I hope I am right as I run out things to eliminate. Cheers Ron.

Hey Ron,
Weather getting colder and my ones back up to the same old tricks which has prompted me to remember to check in with you and see how the ecu replacement worked?

Hi Mcgregor,
haven't been back on this site for years.
But did resolve issue on the BMR Passat it turned out it was the sender ring that's pressed onto the rear of crank shaft which is impregnated with metal that gives the RPM sensor the signal basically looks like the old Beetle rear main seal.

Was $180 for new one and borrowed press tool from local VW guys as it is special tool to press it onto crank and that meant removing gearbox and fly wheel obviously.

Like the local Vw guys said with it only coming up as a intermittent RPM sensor code they to would of replaced the rpm sensor as well never thinking it would be the metal impregnated seal.

Glad that head ache was over many years ago, still have the old girl and she's up to 320k and still going, replaced a turbo not long back as banjo bolt oil to turbo blocked and stuffed bearing in turbo, managed to get a new CHAR inner rotating turbines and centre out of Europe for $350 to my door and a bit more spanner work solved that issue but something worth checking and banjo is left hand thread and worth checking every few years.
