I’ve had 3 TDI’s, all of them 2011 models. Driven from 100 000 km to 200 000 km. No problems. I have never even heard of the issues with fuel pump. Anyhow, fuel pumps are not that expensive, if needed to be replaced.
Air suspension troubles are far more common...
They don't get air suspension on the Generation 2 cars in the US.
The HPFP issue seems to be confined to US cars where it appears that diesel lubricity/quality can be an issue thus causing pumps to fail.
Mis-fuelling is an obvious no-no but so is running a Tdi low on fuel.
Regardless of where you are in the world, don't do this and especially don't try seeing just how many kliks or miles you can achieve by running the fuel tank almost dry.
When the pump pressurises the fuel it heats it up.
Not all the fuel sent to the engine is used and surplus hot fuel is returned to the fuel tank via a small cooler.
However the system also relies on the contents of the fuel tank to further cool unwanted diesel.
Therefore the standard advice on here is to treat a 1/4 full fuel tank as EMPTY and to refuel ASAP.
When a pump does fail, it grenades and send shards of metal right through the entire fuel system.
It's a HUGE job to replace parts and it can cost up to $16,000.
