I bought a replacement crankshaft sensor last weekend (c£70) on the advice of a bosch agent (some of you will know that i have had several months of niggly starting problems).
On Thursday the car refused to start at all so I resolved to fit the new sensor myself this weekend.
It was a real pain in the backside, probably made worse by my taking things off to get it at it that didnt really need to come away in themselves.
I attach some pictures:
Pic 332. With everything in sight as normal, the crankshaft sensor is invisible under the oil filter housing and associated cooling pipes and elements.
Pic 343. This picture is more revealing with water pipes moved from oil filter housing but, by now I was beginning to brick it
Pic 346. This picture shows the oil housing off the engine (already, I had completely sh*t myself and was on 2nd pair of tracky bottoms) with crankshaft sensor completely in view ( pic 347)
Picture 344 and 345 show relative strength of the magnetised sensor - it's not really effective to see here but the newsensor (pic 344) could pick the wiper arm up from the windscreen and the old one (pic 345) could just not do it. Hopefully this will resolve my problem as a stronger impulse will be signalled.
I put everything back together and it seems to have worked ...
Some other points worth discussing?
The old sensor was covered in oily residue and there seemed to be oil down it's chute - is this normal?
TDI club (usa) articles suggest that poor hot starting is a VAG issue due to the ECU some people are wiring in temporary fixes to solve this, though this is not for me. At one point I thought this was my problem too...
A friend at work who subscribes to 'Which' magazine said that they (Which) strongly suggest there have been ECU problems with A2 ...
Needless to say this all began to give me the willies and I was contemplating a new car, now hopefully, I don't need to change it.
It's fired up 7 out of 7 today after being left in various states of cooling, typically the medium hot state where invariably it refused to go.
