Now, as I said, I drive for short runs regularly 3 kms - 4 kms at-least twice every day and longer runs every alternate day, will doing this adversely affect the Diesel engine life? Would I be better off with TSI instead purely from a engine reliability perspective? |
The short version of the answer is, buy the TSI.
Before I elaborate, let mention in advance, that while my daily drive is a Vento 1.6 TDI and we also have a Vento TSI in the family, both of which are maintained by me, and so the answer below contains both the practical lived aspects, as well as the theoretical ones. So, here goes:
1. Engine damage: Diesel engines typically take 6-8km to get warmed up to operating temperature. Before that, the engine is suffering more wear and tear, consuming more oil, and giving lesser mileage. Also, because the engine doesn't get to warm adequately most of the time, you'll also get a fair bit of carbon buildup. Technically, we're talking about everything that compromises engine reliability.
Having said that, the kind of life and tolerances these engines are built for, practically, for you, it's unlikely there would be any effect you will see in your maintenance costs, except for increased engine oil usage - I'm guessing an additional 1-2 litres every year, in top-up costs. Before you get psyched, this is expected behaviour, and VW warns you about it as well, in the manual - your expected driving pattern is labelled by VW as high stress driving. I've personally witnessed this increase in engine oil consumption, in 2 out of my 5.5 years of usage, when work meant I was making a lot of very short trips.
2. Higher Torque: High Torque is just one way to enjoy a car's performance. Arguably, the more popular way has typically been the linear surge of power that petrol engines deliver, and that is especially true of the TSI. Both the TSI engine and the DSG gearbox are individually brilliant, but where they shine in the TSI is in the setup; how VW has paired them together. I've extensively driven a TDI + DSG in both the Jetta & the Ameo, and I promise you, the TDI + DSG is not even half as fun as the TSI + DSG pairing. Of course, you don't have to take my word for it; take both cars for a long enthusiastic drive, and you'll know what I mean. And especially the snarl of the TSI as you rev high, plus that continues wave of power is awesomely addictive.
My point is, both cars deliver fun in their own way, so the engine isn't really a + for the TDI.
In fact, I marginally prefer the TSI, purely from a driving POV, for two reasons: that linear, non-stop surge of power I mentioned earlier, and the fact that it's dead quiet, compared to the TDI, which still makes some noise. When I drive, I mostly like to listen to the engine, and don't put on music, so your mileage may vary here. If you have music on all the time, there's much less of a perceived difference between the two from a refinement POV.
3. Lower running cost (duh!) & higher resale value: I'd like to clarify that you're wrong on both counts here:
In 5.5 years of TDI ownership and nearly 4 years the TSI ownership, I'd say that the TSI is actually slightly more expensive to maintain. Service costs are otherwise very marginally lower for the TSI, but every second year, it's recommended that you change the spark plugs, which is, if I recall correctly, cost ~2.5k. So, pretty much the same.
As far as resale value goes, anecdotally, it seems TSI's lose more value compared to diesel - it's got to do entirely with out national aversion to petrol cars. Also, mind you, you're paying quite a bit of a premium when you're buying the TDI, instead of the TSI.
Of course, fuel costs are lower for the TDI, but considering you barely drive, you'll never recover that additional premium you're paying for diesel when you buy the car.
4. Peace of mind of not being worried about terrible FE when stuck in bumper to bumper traffic in Mumbai when on Petrol.: It's true that diesels deliver better fuel efficiency in bumper to bumper traffic than petrol, but again, given how much you drive, I promise you, it barely matters.

In short, as a dispassionate observer, I'd say, logic says, go TSI. Otherwise, both are brilliant cars, and you can't really go wrong with either. So, all the best, and do let me know if I can answer any more of your queries.
