OK, so, 2 weeks ago, multipla refused to start. Cranked over, but would not fire. Diagnostics throws up the dreaded P1320 (crankshaft/camshaft etc)
Got it towed to the garage, and Dan checked with his diags, and said it was a camshaft sensor gone. Replaced, refused to start again, throwing up the P1320 again.
Tried another make of sensor and still would niot fire up.
Finally got a Bosch one, and it started, no fault code, but then refused to start a second time, again throwing up P1320 Further investigation showed that the new sensor was shredded!! :eek:
Dan then looked at the sensor mounting and the gear wheel that it runs on, ( circled in red in pic 1 ) and found that the lipped edge the sender runs on was so worn, (circled in pic 2) that it kept clipping the sensors edge, wrecking it. So, he replaced the gear wheel with a new one, and another sensor. Car now starts and fires up, but still throws up the P1320 fault code , and EML comes on.
Dan has now checked the timing, and the belt/flywheel, (both were renewed just 2 years ago, at £800!!) and wiring, and all is as it should be. Car runs OK, but refuses to clear the fault code, every time it's cleared, it returns as soon as engine started.
MOT due in 2 weeks, and won't pass with the EML and a code flashing. Dan has spent hours trying to solve this one, (and ££'s too probably) going well above normal, but is now running out of ideas. Looks like it might have to be scrapped, and will need to find something to replace it.
Unsure where to go with this now. Any advice??

2 weeks without transport!

Just a guess , but can it throw up that error code if there is a mis match between crank and camshaft sensors?
Could anything have broken off the cam pulley when it failed that is affecting the crank pulley reluctor causing it to give a bad reading?
Do you have one of the ABS testing cardsthat SKF bearings used to give out free at trade shows?
I used one to check the crank reluctor on a Fiat Scudo with the Peugeot engine.
