It appears only in neutral and disappears as soon as you slot it in 1st and start moving even a little. Has anyone else has such a noise? It comes and goes at its own will and mostly comes after the engine has reached around 80-90% of its working temperature ruling out cold start knocking AFIAIK
Also after coming home and parking the car i noticed the engine oil pressure light was glowing a dull yellow. Checked out the manual it said there could be a problem in the engine oil pressure. Decided to go to the workshop to check it out in the morning.
The next day: Me and father went to the JMD Skoda Workshop in Charkop as it is the nearest for our house and have been there once before. The Assistant works manager attended to us quickly as we had called earlier and informed him we were coming. After great difficulty we were able to reproduce the tak-tak sound owing to the heavy rains but the Works Manager said he would call for a mechanical expert to check it out.
Meanwhile, the warning light was found out to be an electrical fault in the instrument cluster as the engine oil sign is next to the handbrake sign it appears with a dull glow only when the handbrake is engaged. The electrical fellow responded as if it was a known issue and then said that if we turn on the headlights then a few more lights would come on. I tried that and lo and behold! the EPS warning light came on with a dull green glow. The works manager said the instrument cluster will have to be replaced but they would be able to do it only after a week or so (without providing any valid reason).
The mechanic was not available even then to check out the sound and me and dad were getting late for some other important engagement and the rain had begun relentlessly so the works manager assured perfect attention if we came tomorrow morning and hopefully it would not be raining then and it would be easier to isolate the sound. Waiting to visit again in the morning.
All recommendations and advice is welcome as this is our first over-engineered European vehicle and it has barely been 3 months and 1000 kms in the Yeti.
Almost forgot another worrying detail: As soon as we reached home from the workshop, there was a weird smell coming from the exhaust after parking and also there was a lot of smoke(mostly white, almost transparent) coming from the exhaust. It was raining very heavily on the way back if that fact is of any help.
Sorry for the long post but I am kinda worried.

Hi Sid,
First of all, check the battery connections on your car. They should be fully tight and there should be no corrosion on the terminals. Such issues of random lights/ flickering is often caused by weak electrical contacts. The second possibility is of water damage to some cable which is causing current leakage- this should also be diagnosable with a VAG Scan, which can indicate where there is a current leakage in the wiring harness.
In Mumbai it is raining quite heavily and you need to be a little extra careful with the electricals.
What I also suspect is that you are having an issue of brake calipers jamming, either due to rust on the moving parts or mud. In rainy seasons it does happen once in a while if the car is not driven frequently. Check your brake discs and the brake pads for free movement.
On the tak-tak sound, is it regular / periodic or is intermittent? In lower temperatures (below 20 Degrees) the diesel engines take some time (upto 10 min) to warm up and then the clattering noises reduce. Before this, you will find the clatter a lot more). The clattering noises are due to the valve mechanisms and the cams, which abate once the engine warms up and the oil supply is sufficient and at a warm temperature. Do check the oil level in the engine yourself that it is sufficient. It is also possible that the oil level may have fallen due to low oil level. There is a remote chance that the oil circulating pump which feeds oil to the valves/ cams etc may be damaged - do get this checked asap, as if you continue driving the car, it can cause a lot more damage.
The oil pump if damaged should certainly throw up error codes with a VAG Scan if the oil pressure is not enough.
On the exhaust smoke smell, it is ok once in a while for the engine to go in DPF regeneration mode, wherein it runs the engine at a higher speed to make the exhaust temperature higher to burn the deposits in the Diesel particulate filter.
But if the smoke is also white in colour (and not steam from water) you need to be more careful as white smoke is often a sign of an Oil starved engine.
Some of these issues should be easy to pinpoint with a full diagnostic scan of the car (apart from the brakes issues), so do get a full scan done and preferably in front of yourself in the workshop.
Hope you do get the resolution to your issues quickly. Do keep us posted.
