Are you ready for spring?

As we head closer to spring, we’re predicting that there could be a perfect storm of factors that, if they align, could see a potential influx of vehicles into workshops.

The spring months of 2021 have, more than any other, the potential to be a key time for workshops, with a number of factors pulling in the same direction to create a busy time of year for mechanics.

EU and EFTA data shows that new registrations have generally been at their highest across March, April and May in the last 5 years, meaning annual servicing, vehicle worthiness tests and check-ups will likely fall on the anniversary of the original vehicle purchase.

This data reinforces Autodata’s Most Serviced Vehicle report, which shows that March was the most popular month for vehicle servicing and repairs in 2018 and 2019 as mechanics call upon the specs and instructions they need to test and fix a vehicle to get it back on the road.

2021 also brings in the unique aspect of COVID-19 as likely to influence bookings. The pandemic forced several governments to allow motorists to delay legally required vehicle checks past their original due date and these delayed tests and services are now likely to start to feed into workshops over the next few months.

With unprecedented vaccination programmes under way globally, governments are keen to relax strict lockdown measures, refuel the economy and get workers back into offices. With workers remaining wary of using public transport, there is currently a greater temptation to drive to work. But for many homeworkers, having their vehicles parked up and little used for long periods, especially over the winter months, problems are highly likely, requiring the attention of and a thorough safety review by the workshop. 

Home deliveries grew significantly as a result of the pandemic. Autodata saw a 19% rise in requests for LCV service data between Q1 and Q3 2020 as online delivery services expanded, all of which will now be reaching their anniversary and require workshop attention.

So, to help prepare, we’ve listed the key operations our data tells us you could come up against if all things align for a busy spring period.

Key spring servicing operations

Air conditioning

Cars parked for long periods of time attract moisture which can corrode air conditioning valves. Rubber seals are also likely to degrade over time without regular use. Autodata’s air conditioning module contains system information, layout and wiring diagrams to help technicians with service and repair.


Under normal conditions cars should be run at least once a week in order to prevent battery degradation. Cold weather can further worsen battery performance and off-the-shelf jump starters can harm long-term battery life. Consider offering your customer an early battery replacement, especially if the vehicle has been unused over winter. Autodata’s battery module includes information on battery disconnection and reconnection – increasingly important with more connected vehicles.

Windscreen wipers

In addition to tears created by use during winter months on frozen glass, windscreen wipers will crack and degrade under cold conditions. Windscreen wiper blades should be replaced at least once a year or when the blades are no longer making contact with the surface of the windscreen.

Wheels & tyres

With many consumer tyre inflation pumps powered off the car’s 12V supply, vehicle owners working from home are likely to neglect tyre pressure for fear of draining the battery, potentially leading to increased wear on the tyre and even damage to the internal structure. It may also trip tyre pressure monitoring systems which may require diagnostic tools to reset. While local authorities have in some cases been using lockdown as an opportunity to repair roads, winter potholes can also damage tires and wheel suspensions can become misaligned. Check that your customers’ tyres are safe and ensure that their geometry is correct. Autodata’s dedicated Wheel Alignment module includes a comprehensive guide on subjects such as camber angle, ride height, tyres, and adjustment procedures, while the Tyres and Tyre Pressure Monitoring System modules show correct pressures for each wheel size and special procedures around resetting TPMS systems.


Potholes are caused by the expansion of water that freezes in cracks in the road. Vehicles driving over the cracks deepens them and may cause damage to tyres, alloys, springs, suspension components and move wheel alignments, making these must-check areas when vehicles come into workshops for spring servicing. Vehicles which have seen limited use over lockdown may also see suspension failures due to cracks and corrosion – Green Flag reports this is especially dangerous in areas near salt water which can severely weak a spring if cracks should form in the plastic coating.

Autodata provides workshops with the technical data required to service, maintain and repair 99% of vehicles on the road. If you haven’t got Autodata installed, your first month is available at a reduced price. For more information visit
