🚗 BMW 640d GRAN COUPÉ-BEFORE & AFTER

This BMW 640d Gran Coupé came to us with a swirl flap fault, causing the car to repeatedly go into limp mode.

🔧 The problem:
The swirl flaps were faulty and replacement was looking at around £300–£400.

💡 Our solution:
Rather than replacing the flaps at that cost, we carried out a cost-effective solution to resolve the issue-completed for a fraction of the price.
✅ Fault resolved
✅ Limp mode issue addressed
✅ Major saving for the customer
✅ No unnecessary expense

Another example of why proper diagnostics and the right solution matter.
