Hi guys and girls im back in a a4!!! swapped a 07 mondeo zetec for a lovely 55 se avant 2.0 tdi on 167000 (wish it was the 1.9) drives absolutely faultlessly at a cruise has all its power goes through the gears perfectly. But (always a but) she is a pig to start no matter hot or cold at least 5 sec of cranking before she even splutters, and still need to hold the key until the revs pick up. i get the flashing coil light constantly flashing when she is running. Only code stored is p0727 engine sped sensor no signal (along those lines) now the guy i got it from showed me that about 2 days ago he had a new cps fitted (audi genuine) iv noticed that the wiring has been played with in the past and am after the correct 3 pin out diagram from the cps to the loom. so that way i can know 100% this is correct. Another thing to note is that coming to jnc ect she will randomly just cut out and a pig to start again unless im quick to dip the clutch. I have rad about the 461 relay and cam sensor, i have a voltmeter but electrics are not my thing. Any help is greatly appreciated.
