Indeed? I would request them to verify the pricing and inquire if they will be replacing the timing chain as well. That has the potential to significantly raise the price to the level of the first quotation you received. The company promotes its services and repairs for a set fee. I just had my vehicle, a 2017 Grand Sport Elite 2.0cdti 170, serviced. The repair included replacing the timing belt, water pump, and labour, which was estimated at £499. Additionally, the 6-year service, including parts and labour, was priced at £235. All the components used were authorised by Vauxhall. The cost would have increased by around £170 by employing authentic components.
