Hi all, I've recently had some issues with my Ibiza starting. At first it was the odd few extra seconds cranking, or it would fire on the second attempt. It then packed it and cranked no start. Code read it (not vagcom) and it gave "Engine speed sensor - No signal". Checked the wiring, checked for continuity between the CPS (crankshaft position sensor) plug and ECU and ensured the sensor itself wasn't open circuit. Checked the plugs and terminals, cleaned them up and put it back together. It then started, I cleared the codes and went on my way. It worked for a day or two then returned to a crank no start state. Rechecked the wiring, cranked with camshaft position sensor unplugged which made no difference. Ordered up a crank sensor and oil filter housing gasket from TPS and got it today. Bit of a pig, oil pressure switch off, 4 filter housing bolts off (snapped my ball-end hex in one, lovely). As I was on my driveway I left the coolant lines connected and the turbo oil feed pipe. Some more swearing later I got the pesky 12 point bolt out holding the CPS in and tried to budge it.
