I have similar issues and today I'm going to swap crankshaft speed sensor... Hope it will cure jerkynes and I'll keep you posted.

It's not the sensor, it's "CRANKSHAFT PICKUP SENSOR RING 0515T7" the one under the crankshaft pulley you will have to remove the pulley to get to it. And because I wanted to fix it last weekend but euro car parts and gsf car parts doesn't have it I started looking for the second hand one but every single one was sold. So I bet they go bad very often.

They will if you get it from ECP! They do have a poor reputation here amongst myself and other members for dead parts, parts broken, not working that have caused wasted time on tracking non-existent faults when it was faulty parts.

Was your ring mechanically damaged? It should just be a ferromagnetic passive ring, can't understand what could fail if not damaged (broken tooth...)?

AutoDoc holds them on stock for aprox. 15 EUR or less (Febi, Swag, INA, Corteco)

no, it wasn't visually. I'm not familiar with those it's my first one ever done.

My 407 has done this since I had it. I put it down the auto box. Then it's started doing it on very light revs. I've unplugged the MAF (which throws the light on after a couple of starts but no limp mode) it's not done it since. Just need to give the MAF a clean now.
