Distance to a marque dealer from Potters Bar is the single biggest variable in what this ends up costing, and it is worth settling before anything is towed. Operators around Potters Bar tend to run vehicles hard and top up from bulk, which puts fluid quality rather than driver error at the top of the likely-cause list. A drain done on the day is usually cheaper than a recovery plus a workshop slot plus the wait, but that is only true where the contamination direction allows it. Seasonal contrast matters here — summer calls skew towards wrong fills at the pump, winter calls towards level and quality warnings that turn out to be temperature-related. None of the local detail changes the verdict: the direction of contamination decides what is recoverable, and the postcode does not. Frequently needs SCR component work rather than a drain.
