Haval H9 Problems

You either have a problem with the temperature sensor or the gauge in the dashboard itself. Suspicions would be that it’s the sensor at fault which is not sending the correct signal to the gauge to make it read the actual temperature of the engine. If that’s the case, the sensor would also be sending false information to the car’s engine-management computer, and that’s why you have the check-engine light illuminating. The computer is getting confused at the discrepancy it’s seeing, and firing the engine light to warn you that something’s not right.

Either way, this is a warranty issue, so make it Haval’s problem.

This automatic stop-start is an increasingly common feature on new cars and it's designed to save fuel by switching off the engine when you're, say, waiting at a red light. A lot of people find this function annoying and wish to turn it off permanently.

Depending on what version of the H9 you have, there should be a small switch down low on the centre console (near the hazard flasher switch) This will be marked with the same A-in-a-circle and, once you press it once, will disable the stop-start function. The catch is that you have to press this button every time you restart the car to disable the function.

But if you go into the Settings menu on the info-screen, you should also be able to find a listing for the stop-start function which, if you disable it this way, should keep it switched off.

There’s nothing wrong with having your vehicle serviced by a non-Haval mechanic as a registered workshop will still be authorised to stamp your service booklet and maintain your factory warranty. For many people, a non-Haval workshop is the logical choice as the Haval dealer network is not as wide as some of its competitors. But some independent workshops will forget or not know how to cancel the service indicator on the dashboard, and that’s probably what’s happened in this case.

While some makes and models have a simple, DIY method for cancelling this reminder, it seems these late-model Havals do not and the service indicator needs to be cancelled via the diagnostic port and a laptop with the correct, Haval-specific software. Which could mean a trip to your nearest dealer. The other option is to phone around local workshops to see if they have the software to perform this task. The third option is to put up with the service indicator beaming at you constantly and remembering when the next service is due.
