The Golf had been struggling on Stoner Hill near Petersfield, Hampshire, before the owner brought it into White Rose garage on Station Road. A loss of power in a modern turbocharged car normally points toward a failing turbocharger, a sensor fault, or a blocked intake. It was the last of those three, in the most unexpected way possible. A squirrel had packed approximately 100 acorns into the air intake pipe, restricting airflow so severely the engine could barely breathe.
Garage spokesman Leigh Belton confirmed it was not a one-off.
"It was the second acorn-related incident we've seen this week and suggest drivers consider anti-rodent tape to prevent future problems of this nature."
Two acorn incidents in a single week at one garage in one Hampshire market town is not a coincidence. It is a pattern, and it is not unique to Petersfield. Squirrel damage to parked vehicles has been a documented nuisance across the UK and North America for years, with mechanics reporting everything from acorn hoards in air filters and exhaust systems to chewed wiring looms, destroyed spark plug leads and nests built inside wheel arches. Modern cars have made the problem worse rather than better. Engine bays are warmer, more enclosed and quieter than they used to be, and many manufacturers now use soy-based coatings on electrical wiring, which rodents find considerably more interesting than the petroleum-based alternatives they replaced. What was once an occasional oddity has become a regular enough occurrence that mechanics in high-squirrel-density areas now check intake pipes and air filters as a matter of routine.
The grey squirrel, introduced to Britain from North America in the 1870s, does not actually remember where it buries most of its food. The animal caches nuts obsessively during autumn and early winter by instinct rather than by plan, and retrieves them later by smell rather than memory. That system works well in woodland. It works somewhat less well when the hiding spot is a VW Golf air intake. The squirrel presumably considered the warm, enclosed pipe an excellent larder. The Golf disagreed.

For drivers who park under trees, particularly oak trees in autumn, the practical advice from mechanics is straightforward. Anti-rodent tape, a foil-backed tape treated with capsaicin, can be wound around wiring looms and intake hoses to deter chewing. Strong-smelling deterrents including peppermint oil and mothballs placed in the engine bay have a reasonable track record. Leaving the bonnet open occasionally removes the warmth and darkness that makes an engine bay attractive as a food store. And if the car starts running rough for no obvious reason, it is worth checking the air intake before calling the turbo specialist.
The Golf's owner, at least, was spared the £1,200 bill. The squirrel, reportedly, was not available for comment.
