TI decided to order the decoders from Andi for the sidelight errors I was having, though I haven't fitted them yet I'm hoping it will cure the problem.
I'd much rather that than changing them out for incandescent lamps.
Dont worry the extra little decoders seem to satisfy the sidelights without any trouble its just the drl thats been a pig on the 07/08 a3 / s3
