Reinhard Leimroth was trained as a diesel technician by Robert Bosch in Germany in 1956. He has been working on diesels since that time and loves nothing more than to talk about diesel and share his passion with others. He was sent to Australia as a troubleshooter by Bosch in 1960 and was based in Sydney. His troubleshooting and specialist diesel skills meant that he traveled throughout the country to many unique places solving diesel problems that others could not. Such jobs included getting large road train trucks moving again in the central desert to repairing large ship engines on Sydney Harbour and tuning Naval Patrol boats for increased performance. He was also manager of a large diesel workshop and pump room in western Sydney for many years before moving to the historic township of Berrima where he set up the business ‘Berrima Diesel Service’.

Andrew Leimroth was born in 1968 and loved pulling things apart and putting them back together from an early age. He followed in his father’s footsteps and studied to become an automotive technician upon leaving school. He achieved national recognition awards during his mechanical studies and is Australia’s premier turbo installer having personally fitted 3 turbos a week for the past 20 years. Andrew is now the CEO of AWDTech, the parent company of Berrima Diesel Service.
