Hi 

I had my 2013 Audi A3 1.6TDI remapped from 105hp to 135hp about 9 months ago, never had any problems been fantastic. But recently when accelerating hard the engine will pretty much go into limp mode and the coil shaped light starts flashing? As soon as I pull over turn the engine on and back off the light goes and the car works perfectly.  It has always started first time. 

When scanning with the Carista OBd scanner 6 Faults detected - I get Heater & Air conditioning - 262914 

Central Electronics - 262934, 266756, 267030, 787211, 787465  

Could it just be as simple as replacing the glow plugs or would they not affect the car when accelerating? 

Thanks any advice is useful 

Hello Alex from the Homeland.

If it were mine, I would be making some enquiries with the folks who remapped it for you. 

Glow plugs? Highly unlikely I would have thought, since they only assist cold starting. 

Kind regads,

Gareth.
