I also had my dipstick end break off recently but this is now a minor worry.
I am in the middle of replacing the engine on my 1.4 TDI. I have a replacement from a Polo and thought I had swapped all the relevant bits until I noticed the oil level sensor. The Polo doesn't have this although the casting is essentially the same on the front of the engine as on the Audi but they haven't bored the holes for the sensor and mounting bolt. Of course I have only seen this after changing the cambelt etc. and in any case I don't think I can get the toothed wheel on the crankshaft off. How tight is that?The casting is behind this wheel.
So firstly, has the Polo 9N an oil level sensor, it seems not but if so where is it? Secondly could I just continue and not bother with the sensor or bridge the terminals so it doesn't operate the alarm and warning light? ( is this going to happen?) Or another possibility is to drill a bolt mounting hole for the sensor, fit the engine see if it works and if I have an issue with warning lights and buzzers, I could take off the sump and drill a hole fr the sensor from below. Is this a stupid plan? I'm not sure which is the best and or quickest route. Can anyone advise?
Also am I just stupid but if I want to start a new thread, for example to discuss this sensor issue, where do I find the link to do this. I have had this problem before on the site ( although not always) and have had to give up.
Thanks
