Hi,

 

As title says.. struggling to hit 90, seems to take a while.. longer than usual. Also can drop a little during a journey too - this isn't normal.

 

Possible issues? Thermostat? 

 

Cheers,

Not sure on the RS3 but I had the same issue on the RS4 I used to have and the thermostat itself was about £90 IIRC - then labour on top too if you’re not doing it yourself

Yeah I was leaning towards the Thermostat tbh..

 

Just rung my Local Dealership East Kent Audi - Quoted £105 (inc VAT) for it including housing.

Update: N492 Valve cured the issue. Water Temp warms up much quicker and sticks to 90.
