Vauxhall Corsa 2017 1.4 Elite EcoFlex - Car won’t start and says it’s overheating - omgitsmrsv
Hi all,

I was booked in for an MOT and service the other day and when I went to start my car it refused. When I start the ignition the engine turns over and seems to catch, but cuts out straight away. It is also giving messages about the engine overheating, but the engine is running for literally seconds, so I don't think this is actually the case. The first warning is about the AC being turned off due to high engine temperature and the second warning, which shows up after sitting with the ignition at position 2 for a few minutes, is one about the engine overheating while idle (but the engine isn’t idling, because it’s already cut out by that point...).

Really I’m just looking for a bit of a steer on what this could be and how expensive it’s going to be to fix. I’ve contacted a garage and I’m waiting for a reply from them at the moment, but thought I’d ask here too.

Thanks,

Beth

I would say you have a faulty coolant temperature sensor. This is reporting that the engine is hotter than it actually is. Consequently it fuels for a hot engine rather than a cold one. The fuel mixture is therefore too lean and the engine won't run.

Thank you, that’s very helpful. :)

Sound advice from above . Have you noticed the engine temp gauge reading too high ? It uses the same sensor . Also , may be an idea to check the engine coolant level.

Hi, just wondering if you ever got to the bottom of this? I have the exact same car and exact same issue. Thanks
