Volkswagen Tiguan 2012 Problems

There’s more factors than distance covered when it comes to diesel fuel-injector lifespan. That said, modern, common-rail diesels do seem to work their injectors pretty hard, so it’s possible that yours will be ready for replacement at 165,000km on the odometer.

Other elements that will contribute to injector wear are fuel quality, dirty fuel filters, the overall condition of the system including the fuel pump and simply how well the vehicle has been maintained generally. How it’s been driven will also have a bearing on injector life, including whether it’s been used for highway travel, urban running and whether it’s been used to tow relatively heavy loads.

Fuel-injectors can be rebuilt or reconditioned, but the trade reckons that a reconditioned injector will have about half the useable lifespan of a brand-new replacement injector. As for injector servicing intervals, I’d be guided by what Volkswagen says in its factory service schedule.

All model years 2008-2013 appear to be affected.

We understand a new tensioner was fitted from 2012.

Dealers are now looking for ways to boost profitability, with all sorts of added-cost extras that are good for their bottom line but not for owners or their vehicles. The bottom line is simple: if the car is operating fine, and the suggested service is not on the list of manufacturer requirements, then say a big NO.

It is disappointing when you have spent a lot of money buying what you believed was a quality product to find the truth to be something else. Getting the runaround from the company just adds to the frustration. The only thing you can take some comfort from is that the problems to date have been fixed, and you really can't predict what might or might not happen in the future.
