During his Radio 2 breakfast show on Friday, Wogan told 8 million listeners he had called Mercedes Assistance at 11am having discovered that the car did not come with the correct bolts to fit the spare wheel.
The vehicle was recovered at 5.30pm after two failed attempts; the first truck reportedly went to the wrong BBC centre, and the second was too small to tow the luxury saloon.
In its statement, the manufacturer said: “We are making a personal apology to Sir Terry Wogan for the exceptionally poor service he received recently.
“Our customers have the right to expect a high standard of service and we clearly failed to deliver on this occasion. We’re looking into every aspect of what happened to ensure that no other Mercedes-Benz driver has the same experience.
“It would be inappropriate for us to comment further until we have investigated fully."
