What can water leaking from the exhaust pipe mean?
Water drips from the exhaust pipe and the question arises: is that normal, or is some problem with the engine starting? Many drivers notice it especially in winter or in the morning after starting ...
Adding oil – on a cold or warm engine, and how often should you top up the lubricant in your car?
A low oil level is one of those problems drivers often only notice once the engine starts running louder or the oil warning light comes on. And by then it can already be very close to a serious fai...
Your diesel has no power? There can be many causes
A diesel that suddenly starts accelerating poorly does not always mean a damaged turbocharger or an expensive rebuild straight away. In many cases the problem begins much more "down to earth" – wit...
Water in the fuel – symptoms, effects, how to get rid of it? Find out!
On the face of it everything works normally, but the car starts losing power, is harder to start or jerks strangely – and that's usually exactly when a problem begins that can't be seen with the na...
A damaged catalytic converter: symptoms
Problems with the catalytic converter rarely appear suddenly. Usually it starts innocently – the car loses a little power, the engine runs less evenly, fuel consumption slowly rises, and a strange ...
B0 fuel – pure diesel with no biocomponents. What is it, where can you buy it and is it worth it?
B0 fuel is pure diesel with no added biocomponents (FAME) – the kind we used to fill up with before 2009, when the EU imposed mandatory blending. It is valued for its stability, its resistance to m...
Oil in the coolant – which symptoms shouldn't be dismissed?
Sometimes one look into the expansion tank is enough to know that something bad is starting to happen in the engine. A greasy layer appears on the surface of the coolant, the colour turns suspiciou...
Fuel pump replacement – how much does it cost, how long does it take and how is it done?
A fuel pump very rarely fails from one day to the next. Usually there are small signals beforehand: the car starts worse, sometimes it jerks under acceleration or loses power at higher revs. Many d...
A faulty water pump – what are the symptoms, the causes and what about the repair? Rely on proven advice
Has your car started behaving strangely – the temperature climbs one moment, you hear a worrying whine from under the hood the next, and something is dripping onto the driveway? Very often the prob...
Oil in the exhaust: causes, effects and solutions
First a dark stain appears at the exhaust tip, then you notice the characteristic smell of burnt oil. After a moment you start wondering whether that's normal, or whether something is beginning to ...
Symptoms of a clogged catalytic converter
A drop in power, higher fuel consumption, strange engine behaviour – many drivers put it down to “the car's age” or poorer fuel. Meanwhile, the culprit is very often a clogged catalytic converter, ...
Metal filings in the fuel: how do you recognise them?
Sometimes it all starts with a trifle. The engine cranks a little longer when starting, the car loses its urge, and fuel consumption suddenly rises by a litre or two. Many drivers put it down to fu...
Types of diesel fuel: B7, B10, XTL and the seasonal grades – which diesel for which car?
At Polish stations diesel comes in three official designations shown in a square label: B7 (up to 7% FAME biocomponents), B10 (up to 10%) and XTL (synthetic diesel with no crude oil). On top of tha...
B7 fuel for diesels – the key facts
B7 is standard diesel with up to 7% of the FAME biocomponent added – the fuel you will put in the tank today at practically every station in Poland. It is safe for the vast majority of diesel engin...
A noticeable smell of petrol in the oil – the problem may be a leaking petrol injector!
Sometimes it's enough to unscrew the oil filler cap or check the dipstick and a strange impression appears – the oil smells of petrol. Many drivers ignore this signal at first. The engine works, af...
B0 or B7 diesel – which fuel should you put in your car?
In most cars you simply put in B7 and that is fine – provided your engine’s manufacturer allows it. B0 is pure diesel with no biocomponents: it copes better with frost and long storage, but it is m...
The DPF warning light – what to do when it comes on?
A DPF warning light does not always mean a breakdown requiring a flatbed and an immediate rebuild. In many cases it is simply a signal that the particulate filter has collected too much soot and ne...
Injector regeneration – when can injectors still be saved, and when is it better not to “resuscitate” them?
Injector regeneration is not a matter of quickly “flushing through” the fuel system and clearing the fault codes. It is a full diagnostic and service procedure whose purpose is to restore correct f...
High idle speed – why does the engine rev up on its own when idling?
If the engine spins faster than it should when idling, it usually means something is going on with the air supply or with the control electronics. A properly warmed-up petrol engine should hold rou...
Cold engine starting problems – the causes and how to deal with them
If the car cranks for a long time before it fires, or in a frost will not start at all, the usual culprits are: a blocked fuel filter, water and wax in the diesel, worn plugs (glow plugs in a diese...
Look after your radiator to avoid costly failures – see how to do it with TEC 2000
A working radiator keeps the engine at operating temperature and protects it from overheating. When it fails, you are no longer talking about hundreds but thousands of euros – because overheating b...
How to burn off the DPF while driving? Regenerating the particulate filter in practice
A DPF does not block up suddenly, overnight. Most often the problem builds up gradually – the car tries to start a regeneration more and more often, fuel consumption rises, a sluggish response to t...
How to check whether the thermostat in your car is working?
If you have the impression that the engine takes too long to warm up, or the opposite – the temperature starts climbing faster than usual, your first thought should be simple: check the thermostat....
Why does the engine stall at idle? Intake, fuel and electronics under the microscope
The car starts normally, you pull away, everything is fine… and suddenly, as you approach the traffic lights, the engine stalls. No warning, no message, just silence. This is one of those problems ...
