Arranging the work for the Z4
Need a diagnostic check for the 2020 BMW Z4? We arrange it with a trusted shop; the work is never done by CarmaCars. A steady check engine light needs a check soon; a flashing one means pull over safely and get help.
About your Z4
Bring the owner's manual or service records if you have them. Mention the trim and engine in your request; parts differ between them. If you have the service history of your Z4, have it ready for the shop. Under the hood: the 2.0L 4-cylinder turbo and rear-wheel drive.
What CarmaCars does here
We follow up until the shop has the car booked in. We keep you posted until the car is booked in. Send the car's details and what it needs; we take it from there.
Stay on the road
If the repair runs long, keep the rental longer. Pick a car that suits your week from our fleet. We deliver across the Toronto area, or you collect the car from our location for free.
What to ask
Ask what warranty the shop gives on its parts and labour. Ask how long the job should take, so you know how long to rent for. Ask how the shop takes payment before you pick the car up.
Small things that help
Look at the tire tread before long trips. If the car pulls to one side, ask the shop to check the alignment and the tires. Have the battery tested before winter if it is more than a few years old.
Questions first?
Need the work and a rental? One request covers both.
