You could have an engine problem that is causing the vehicle to lose power. The cause of this could literally be a thousand different things. An electronic scan of the vehicle might shed some light on the root cause of the problem, and most mechanics would carry out such a scan before doing anything else.

If the engine is not at fault, you might find the problem can be traced to a transmission that is not shifting gear properly or is slipping, or perhaps even something as simple as a dragging brake or poorly adjusted park-brake. But before you hit the workshop, you can check simple things like the condition of the engine’s air filter to make sure there’s no obvious cause. If your car is a turbocharged model, check the plastic trunking that carries the boost from the turbo to the engine’s intake. This trunking can split or fall off, leading to a loss of boost pressure and, therefore, performance.

These little LED info-screens have been part of dashboards for years now, and they’re a known problem in many makes and models. There are specialist repairers who can either fix the screen you have or remove the dud one and fit a new one. Making sure the odometer still reads to car’s correct mileage is the trick.

Actually, that’s an important point, because a correctly working odometer is a roadworthy item. And one that flashes on and off randomly is definitely not working properly and is, therefore, making the car technically unroadworthy.

You can replace the head unit in your car to a more modern one that features Bluetooth. Make sure it gets installed properly to ensure that the full functionality is retained.

The alternative these days (provided you’re happy with the rest of the stereo’s performance) is to install a small transceiver that fits (usually) into the 12-volt power socket and accepts the bluetooth signal from your phone. From there, the unit transmits that signal via an FM frequency which you tune the existing stereo to. Some of these units work better than others, so paying a bit extra is probably worth it.
