You start your car up, and nothing, the dashboard stubbornly refuses to light up. The engine is dead, kaput.
A likely culprit is the dashboard or cluster itself rather than the engine. Many car companies buy these in and the electronics are notoriously prone to vibration and damp. Unfortunately, cars do move and get rained on. A lot if you live in England.
So the normal cost if you take your precious car to a garage is about 15 mins work and £1200 at least for the new cluster.
