ally Posted March 27, 2008 Report Posted March 27, 2008 i had to replace my engine on my galaxy mk1 1997 tdi because a piston ring broke and was told too much to fix engine thats in the car. my engine is and was a vw engine. had the engine fitted and all is fine except when you drive over 70 mph. the car will loss all power between 70 - 80 mph and to restore it i have to turn the galaxy off and restart the galaxy and after that the power will be restored. all was fine with my old engine installed no power loss at all. the guy who fitted the engine wasn't sure exactly how the pipes on the turbo go as fords was the ones who removed the turbo but didn't refit it, as they wasn't intrested in repairing the engine or fitting a nother one. oh new engine is a second hand one not new. there are two small pipes one blue and one red these are the pipes he isn't sure on. tryed them both ways and still the same. i have unpluged the maf sensor and the galaxy drives like it does when it loses the power so that makes it worse, so don't think the sensor is faulty. it is possible that the guy who fitted the engine has pipes wrong or wiring or spit pipes, anything like this i think could be the problem , but i never fitted the engine so dont know where to look to see if it is all ok. manual doesnt really show where all the pipes should go. can anyone help ? if possible could anyone help by explaining where to look of a picture would be good.

ini Posted March 27, 2008 Report Posted March 27, 2008 (edited) Your 'Limp mode' could be due to a few different problems (mostly boost & boost control related) Leaks in the vac control tubing, MAF, failing/blocked/wrongly connected N75 boost control valve, sticking VNT mechanism on 110bhp upwards, or oil fouled wategate actuator on 90bhp engines are some of the main culprits for 'overboost' or 'underboost problems. These links are useful for your engine: http://forums.tdiclub.com/showthread.php?p=714028 http://forums.tdiclub.com/showthread.php?t=179589 Most likely vac control leak or vnt 'vanes' sticking. (power loss around 3000rpm in 3rd gear or above, under load/hills or motorway speeds. Cycling the ignition restores power) Edited March 27, 2008 by ini Quote

ini Posted March 28, 2008 Report Posted March 28, 2008 Turbo control pipe info: The diagram on the left is for 90bhp models with an external wastegate. The diagram on the right is for 110bhp+ models with VNT turbo. http://i118.photobucket.com/albums/o99/inisj/N75earlyandlate.jpg Quote
ally Posted April 17, 2008 Author Report Posted April 17, 2008 sorry its been awhile but an update. i have changed all pipes , taken turbo off cleaned it and replaced all gaskets. checked for leaks but dont seem to be any now. how do i test to see if the wastegate is sticking ? i have found a few things the guy had put on wrong and have put them right, if i take a photo of the pipes from where they are and to where they go could some kind person let me know if they are right. oh one more thing rang vw and got a price for a MAF sensor and it was Quote
ally Posted April 19, 2008 Author Report Posted April 19, 2008 (edited) hi i have taken some photo and uploaded them could some nice person take a look and see if all the pipes go to where they should go. also i have changed all the pipes so the blue and red are black now, but have put what ones they are on the photo. also if you need more photos or there not clear enough then let me know , but think there not too bad photo.thanks http://www.freeimagehost.eu/image/63b0d82997557http://www.freeimagehost.eu/image/2cacd02997558http://www.freeimagehost.eu/image/5462a92997559http://www.freeimagehost.eu/image/e8e7942997560http://www.freeimagehost.eu/image/7e98972997561http://www.freeimagehost.eu/image/33794f2997562http://www.freeimagehost.eu/image/7666d92997563 Edited April 19, 2008 by ally Quote
ally Posted April 24, 2008 Author Report Posted April 24, 2008 i have now changed the mass air flow sensor and guess what, still the same. does anyone know what else it could be ? Quote
big_kev Posted April 24, 2008 Report Posted April 24, 2008 Sounds like a lack of fuel.....dodgy pump maybe ? Could also be something electrical confusing the ECU...less likely. Quote
NikpV Posted April 24, 2008 Report Posted April 24, 2008 since its going into limp home mode I think you need to get the dtc codes read Quote
ally Posted April 24, 2008 Author Report Posted April 24, 2008 (edited) the error code is 00575 Intake manifold pressure Edited April 24, 2008 by ally Quote
