Here is the underbody as it came from the factory
Attachment 2210220

Here it is with the underbody guard installed

Attachment 2210218

Could you please share where did you purchase it from and how much did it cost? Is it the official accessory that is provided?? Any potential risks of this becoming a cozy resting spot for rodents??

PS: I drive a 2020 Polo 1.0 TSI MT

I got it from VW service center itself. It's an official part. It would be different for 1.0 TSI.

I think even without the undertray it would still be a good spot for rodents as any engine area is. That is your call to make.

The damage is close to the bellhousing and the clutch inside is spinning as fast as the engine. A loose bolt or nut thrown off at speed should be enough to cause that damage. Even pieces of a broken spring can cause it.

Guys,

Another incident was reported in social media recently, take a look at the pics and compare them with those on first post of this thread. They are eerily similar and now I'm being forced to believe that they might be result of some issue from within the engine. I guess your conclusion seem logical, all these cars cannot have similar kind of crack and failure.

Although I still stand by my experience of seeing cars with damaged engine components, specially oil filter and gearbox due to flying projectiles, the similarity of failure in these cases is shocking and may be points towards some internal failure.

Regards,
Shashi

PS: In first pic, even the block has cracked. And prima facie MASS is saying its due to hydrolocking.

[Leoshashi]

A chap with over 30 years of experience on Maruti engines, opines that all failures are on oil pan from inside out or block which has cracked(in latest case). Hydrolock related failures look exactly the same, pointing to hole developed in the components.

I'll try to search a pic where BHPian sumitsinha0280's Ritz had turned sideways, causing engine oil to enter the combustion area, and when that engine was cranked, it developed a hole too somewhere with a loud bang. Not sure if it did on block or oil pan.

Will keep you guys updated.

Regards,
Shashi

+1 on this. I would be interested to know if this can be put in place in Taigun specifically.

Hello Leoshashi, thanks a ton for sharing your experience here. I have been seeing your posts on this topic since the beginning of this thread.

I need some help. I am about to take delivery of a Ciaz Alpha this week. This is my first Maruti car. Would you by any chance have any comments / advice about the under body engine cover from Maruti or those available on Boodmo for Ciaz? (I will ask Maruti service advisor too but that would be more than a month away when I take the car for the first checkup).

This thread raised a very valid point. I am frantically searching for an engine cover for my 4 years old car now.

Does anyone know where i may get an engine underside protection cover for Hyundai Elite i20 (Facelift) 2018 petrol model?
