Compare BMW 4 Series engine and cooling repair quotes from specialist garages

Looming hundreds of feet up in Munich's skyline is BMW's headquarters, a vast and impressive building designed to look like four engine cylinders - the configuration that drove much of the brand's early success.

BMW has come a long way since 1927, when it produced its first car, the Dixi, shortly to be renamed the BMW 3/15. In 2022, it was awarded 'Best Manufacturer' at the AutoCar Britain's Best Car Awards, and the same year, it triumphed at the WhatCar? Awards, winning more accolades than any other brand. The M5 special edition, celebrating 20 years of BMW motorsport, is one of the rarest M automobiles in the world.

A typical car engine has around 200 parts, all of which must be maintained and replaced if they stop functioning correctly. As such, car engine repair is a broad term that covers a wide range of problems.

Signs of potential engine issues include loss of power, illumination of the check engine light, a knocking noise, excessive or discoloured exhaust smoke, overheating and frequent stalling. If an engine fault repair is needed, a mechanic will often conduct a diagnostic test first to determine which component is to blame.

An engine oil leak repair is one of the most common jobs done by mechanics; other repairs might involve the engine management light or engine cooling system. Booking a car engine service from time to time is the best way to prevent problems from developing. Not only does it extend the life of components, it often saves you money in the long term, too.
