Volkswagen UK's managing director Paul Willis is due to face MPs on the Transport Select Committee on Monday to answer questions on how the company’s external investigation is going and how it intends to rectify the damage the emissions scandal has caused.
The Society of Motor Manufacturers and Traders' chief executive Mike Hawes will also be questioned on the wider effects of the scandal on the UK's car industry.
Willis will also face the Environmental Select Committee on Thursday.
Volkswagen has said 1.2m Audis and VW models in the UK have the "defeat device", including 400,000 Audi vehicles, 132,000 Skodas and 77,000 Seats. A further 80,000 commercial vehicles are also on the list.
BMW has also been dragged into the scandal after reports that some of its diesel cars, the BMW X3, exceed emissions limits, which the company denies.
Last week VW's US chief Michael Horn admitted that he had been made aware of possible 'emissions non-compliance' a year ago and said it would take at least two years to fix the cars affected in the US and three people have been suspended.
It was revealed last month that the US Environmental Protection Agency and California Air Resources Board had detected software that allow cars to cheat emissions tests, and expected some 500,000 vehicles in the US to be affected, VW has now said more 11m cars around the world are involved.
Several regulators around the world have announced investigations into the issue.
The scandal toppled chief executive Martin Winterkorn, who resigned on 23 September. His replacement Matthias Muller has said he expects VW to start a recall of cars affected in January.
The revelation has driven down VW’s share price by 40 per cent and wiped £20bn off the company’s market value.
