Mobile drain
Expect a fixed price of roughly £150–£300 for a car where the engine hasn't been started, including fuel and disposal. Ours is published on our prices page.
What adds cost
Running the engine (extra flushing and often a filter), AdBlue contamination, large tanks, or needing recovery off a motorway first.
Repairs after driving on
Replacing a diesel high-pressure pump, injectors and lines at a dealer can cost several thousand pounds. Stopping early is the biggest saving you can make.
