Claim travel without a logbook

I have source code 3802 on my IRP5 but I did not keep a logbook, can i claim for the perks tax paid via source code 3802 if I don't have a logbook?

Unfortunately, you can only complete the travel allowance section and claim for business mileage if you kept a vehicle logbook. If SARS does request supporting documents from you, they will require this information to back-up your claim.
