What do I look for when servicing a Mercedes-Benz A-Class?

Answered by CarsGuide 10 Oct 2021

Home servicing is a great way to learn about your car and get a better idea of what makes it tick. It also means you might even become a more `mechanically sympathetic’ driver and be kinder to the car in a long-term sense.

The service booklet in the car’s glove-box will tell you a lot about what you need to know when it comes to what’s required for a service. But remember that not all services are the same: Some are minor services and some are major. Others require one-off actions such as changing a timing belt or checking the tension of a timing chain, but you can’t afford to ignore any of these things. Other things required by the factory service schedule include checking the thickness of brake material, changing fluid beyond just the oil and plenty of other tasks that might not occur to you naturally. Most of these tasks are either time or distance-covered dependent (sometimes both).

The bottom line is that you really need to be on top of these tasks and know how to do them before you rip the car apart in the driveway one Saturday and then discover you don’t know how it all goes back together. Home maintenance extends way beyond just oil changing, particularly on a modern design such as the Mercedes A-Class. Modern cars are very complex devices and keeping them running sweetly and safely is often the work of a specialist. That said, I’m loathe to try to dissuade you from tackling a job that can be very satisfying and could save you money in the process.

A lot of TAFE colleges once offered car-maintenance courses for the home mechanic, but sadly, many of these seem to have disappeared due to budget cuts across the education system. It would still be worth talking to your local TAFE, though, to see if there’s a short course that might help you out.

Mercedes-Benz A180 2014: Broken valve spring

Answered by CarsGuide 15 Nov 2019

A broken valve spring is not something that would be caused by the fuel. Most likely the spring was faulty, perhaps there was in inclusion in the material it was made from, or there could have been some other manufacturing problem. Use either 95 or 98-octane fuel.

Mercedes-Benz A-Class 2018: Mercedes Me

Answered by CarsGuide 17 May 2019

Your first port of call should be to Mercedes to register a claim for updating your car. It would help if you had the promise in writing, otherwise who is to say who said and promised what. If you feel strongly about it perhaps you could get other affected owners together and contact Mercedes as a group.

Mercedes-Benz A180 coolant and temperature issue

Answered by CarsGuide 25 Jul 2016

Mercedes-Benz Australia spokesman David McCarthy says: "The issue has been, first, a coolant leak from the thermostat therefore displaying the low coolant level light on a slope. After this repair was completed the customer has started to watch his temperature gauge and found the operation different to what he has possibly experienced on other vehicles. The design of the cooling system has located the temperature sensor in an area where the coolant temperature does fluctuate as the thermostat operates. Stop-start operation can also influence this temperature variance because if the engine is not running no heat is generated. This is normal on the A-Class and has been documented from Germany for our dealers."
