Petrol and Diesel cars splash guards ?

[Klajoklis]

Hey, so I noticed a difference between splash guards for petrol and diesel cars. Basically, petrol cars only has like a front shield, that is only protecting the front part, or as i would say, there is only half of the splash guard that diesel has. Diesel cars has splash guard that covers the whole engine from underneath.. So, why is that, is it because of overheating or why ?

My petrol car has a full engine bay splashguard, a right royal pain to remove when changing the oil and filter.

As per this in quite a few cars I’ve had.

Depends on the car.

Many VW for example have full undertray on both petrol and diesel.

Some TDI have them though , because it helps reduce noise.


My M135i has a full length under tray and it has a flap to access the sump plug. So it doesn't need to be removed!

Hmm, interesting. Audi a3 for example. 1.6 petrol front guard only. Audi with 1.9tdi comes with the full one. Some people on the internet said, that if car comes with front guard only, putting full one might start overheating the engine or at least raise the temperature by some.

Unlikely to overheat in our temperatures, more likely to reduce engine noise. Similar to diesels having padding under the bonnet whilst alot of petrol models don't.

But is the front guard enough for protecting the engine ? Because if it's not, what is the point of it..

Can't really see the point of this thread either.

Same could be said about your comment too.

Point is, i'm trying to find out why are they putting half of the guard if they could put the full ones. I have both of them, but if it came from the factory with front guard only, should I stay with it or should I put the full one. I have a petrol car by the way.

I suspect it makes not a blind bit of difference but you could always ask your local dealer.

Its not a guard,it's an undertray.
My car has neither and I'm worried about it now.......

[Monkeylegend]

Stop, we will be prompting a panic buy on undertrays if we are not careful

This ive seen plenty of smashed sumps mainly on vw group cars as they sit pretty low with plastic covers covering them. Op they aren't splash guards.

All they're for is for stopping dirt and excess water from entering the engine bay. Some do a really good job. Compare two cars, one with the factory splash guard and another one with it missing. The latter will have corrosion and dirt aplenty..

Aww, right, man, right, lets not give a f about older cars, because why should we, huh ? Well I do, I want to keep it at best condition as I can, so that is why i'm asking some opinions

But everyone got butthurt af as I see, hehe. Thanks anyways.

Sorry, many petrols do, probably most of them.
