Crankshaft sensor failure / malfunction on E90

I am having few issues with my car (only 320i) since last week and here are those:

1- Car hesitates on acceleration and RPM drops for 1-2 seconds and regains it. It happens on heavy acceleration though.
2- As above, but car has died twice while on the road (dangerous). The only way to bring it back to life, is to find a safe place and and restart it after taking out / reinserting the key. Engine light comes on.
3- Car failed to start on one ocassion and long cranks on that ocassion.

Inpa suggests:
Crankshaft sensor error

(recorded three times in three different weather temperatures)

I have read few threads on it and my symptoms are similar to those who have had it.

I have already ordered the sensor today and it will be with me tomorrow.

Now on 320i / 325i/ 330i it is below manifold intake. Few threads suggest that it can be changed if you approach it under the engine (should have tiny hands though).

I have few questions:

1- Has anybody had the same issue? Can you share your experience?
2- Has anybody actually managed to change it by himself?
3- I have been quoted 180 + VAT by my local indy. I think that is a fair price considering if manifold has to be removed / tilted. Any suggestions on the price?


Any suggestions / experiences?
