Hi All, 

 

I'm having an issue when car (Octavia 2006) is parked outside in hot summer days (35 Celsius degrees or higher). 

Once I run the engine it starts with turning off the electronic devices one by one.

Within 20 seconds the air condition and its temperature display turn-off. Soon after, the right and left blinkers stop working (strangely all 4 are working fine at the same time) etc. until eventually the engine turns off (not always).

Often cannot start the engine again (dashboard has lights and no error indications on it) until it cools down for few minutes or longer. 

 

No such problems outside summer whatsoever. 

 

Any suggestion on this please? I tried at the auto-repair shop but they had no clue about this.

I have a suspicion there may be a fractured solder joint somewhere in the instrument cluster which is causing your problem.

 

Also you could try carefully and slowly applying water from a hose to various wiring areas in the engine compartment to try and localise things by cooling but I still think the instrument cluster is where the fault lies.

Can you please explain to me, what exactly you mean whan you say instrument cluster?

Do you mean on main electronic boar in front of drivers legs, or something else?

The instrument cluster is the unit behind the steering wheel which comprises the speedometer, tachometer and the other various gauges and warning lights.

 

It is not uncommon for the lead-free solder joints to fail over time causing problems from instrument illumination failure to engine cut-out and non start conditions as it also contains immobiliser components.

 

You will find helpful posts on this forum with similar problems and videos on YT showing how you can remove the cluster and fix such issues.
