2018 Skoda Octavia Pricing and Specs

In most cases, engine life has far more to do with long-term service and maintenance than anything else. A new vehicle with the correct preventative maintenance and servicing can easily cover 200,000, 300,000 or even 400,000km before major work is needed. But the same car with patchy maintenance might last only a fraction of that distance before it needs major engine work. So the service record is where to look first when considering a particular vehicle.

The type of driving the vehicle has done is also important. A car that has spent all its life in stop-start, gridlocked traffic will rarely cover the same distance as a car that has been used for highway driving where it’s in a high gear and just idling along. So try to find out about the car’s ownership history, too.

The price of the car you’re looking at seems to be at the high end of things for this year and mileage, but not by a whole lot. Certainly, most sellers post a price higher than they will take to allow for some haggling room during negotiations.

The DSG gearbox in your car has given Skoda and other members of the Volkswagen family all sorts of grief over the years. The problem you’ve described suggests a build-up of metallic particles (from wear and tear inside the transmission) which are being attracted to the magnetic sensors inside the gearbox and leading to bogus commends being sent to the car’s on-board computer. I’ve also heard of these symptoms being the result of faulty mechatronics and even a software glitch. The mechatronic unit, by the way, is the module that acts as middle-man between the computer and the gear selectors and clutch packs contained within the gearbox itself.

So there are three (among many) possibilities. And the VW (and Skoda) DSG transmission is no stranger to any of them. Either way, a loss of drive at any stage – whether it’s Drive or Reverse – is a potentially dangerous situation and needs to be fixed. Unfortunately, Skoda Australia only extended its factory warranty to five years on vehicles sold after January 1, 2017; after your car was sold. That said, I’d certainly be talking to the brand’s customer relations department with a view to at least finding out what’s wrong and then negotiating on whatever repairs are required.

On the surface, it sounds like the electrical system is somehow letting you down, Todor. The no-charge light comes on because the engine has stalled and is not driving the alternator, so that’s probably not the root cause here. But only when the glow-plug light appears (which it should every time you turn the ignition on ready to crank the engine) will the engine fire. That’s the clue that whatever glitch is at work here has settled down and is allowing the electrical system to work properly. Of course, a diesel engine doesn’t have a spark (electric) ignition system, so we could be barking completely up the wrong tree here. That said, the modern diesel engine does use a series of electric fuel pumps, and a faulty pump could easily cause the problem you’ve described.

With that in mind, the absolute best advice is to take the car to a workshop with the necessary diagnostic gear and have the car scanned to see what fault codes it coughs up. Until you do that, and can isolate the problem, you can run around in circles for months changing perfectly good components in a costly process of elimination.
