Skoda SUV Range

With a full AdBlue tank, your car should be good for the next few thousand kilometres at the very least, not just 600km. This makes me think the sensors that measures the contents of the AdBlue tank are telling the car’s computer lies about how full it is.

As you’ve identified, if the computer thinks the AdBLue tank is empty (even if it’s still full) it can refuse to restart the engine. So you need to sort out the sensor and sender units in the AdBlue tank to make sure that the car know it has plenty of AdBlue remaining. This could involve a recalibration or perhaps some new sensors and parts.

In the meantime, I’d keep the AdBlue topped up to full all the time to avoid being stranded with a car that won’t start. Pay attention to the car’s performance, too. In some cases, the computer will first scale back performance if the vehicle is low on AdBlue before it stops the engine altogether. So any unexplained fall off in performance might indicate the vehicle is beginning to think it’s out of AdBlue.

The Skoda Kamiq is built in Mladá Boleslav, Czech Republic.

Modern cars like the Skoda have sealed cooling systems which means they shouldn’t need regular top-ups. As the engine heats up and the coolant expands, any excess coolant is captured by an overflow tank which stores the coolant and then allows it to be sucked back into the engine’s cooling system as the car cools down. This is all perfectly normal. All of which means that if you have coolant disappearing, then there’s a leak somewhere, but don’t necessarily jump to the conclusion that the radiator is at fault.

The problem could be one of many things, including a failed radiator hose or some other piece of critical plumbing, a faulty water pump, cracked cylinder head, blown head gasket, broken overflow tank, failed radiator cap, split cylinder bore, leaking heater matrix and more. The dealership should be able to tackle this as a warranty job and will probably pressurise the cooling system and see where, if anywhere, coolant starts to appear where it shouldn’t.
