fixed turbo prob, lots of black smoke now won\'t start! help!!!!
i bought a 1996 audi a4 1.9tdi 110 bhp with a turbo fault.
vag com only picked up -
exhaust gas recirculation valve (n18) open or short to ground.
i was planning to replace or at least test the n18 and i found a huge split in one of the major hoses. i replaced the hose and i had a working turbo.
i took it out for a drive and straight away i noticed lots of black smoke from the exhaust when i put my foot down. not put off as was used to some black smoke (the car has done big miles ) and with a big smile on my face as there was torque so i continued.
the car was fine for about 20 minutes and i was getting good response, i tried to push it a bit harder and i lost power and turbo whistle was noisier. i think it went into limp mode which i have heard about??? i drove home slowly with really bad idling and loads of smoke.
i went to try again last night and it didn't start! tried again this morning and nothing. it's always been on the button.
vag-com now brings up........
01265 - exhaust gas recirc valve (n18) - open or short to ground
00519 - intake manifold pressure (g71) short to b+
00550 start of injection regulation 17-00 control difference
how best to sort this???
any help is greatly appreciated as i'm now in the [img]/ubbthreads/images/graemlins/swear.gif[/img] without wheels
