This is in turn is causing your warning gong and its killing the power to these lights as a safety feature, making you think they are not working. Coding should fix that - although if memory serves me right I think you also need the latest FRM3 module, which is your car probably won't have if its of 2007MY.
Sorry for my post being unclear. I have no coding.

I thought they should have at least have some light but what your saying does make sense.

Can the FRM2 not be coded or will i definatly need the FRM3 module. How much would this cost to supply and fit if you know?

I just wanted to confirm as the garage would charge me for coding and it still not work..
