Hello all.


Got a problem with our Audi 80 TDi b4. The headlight bulbs needed changing so I changed like for like (H4 bulb) and they are now working. The full beam no doesn't work and when I press the switch towards the dash for the full beam it cuts the headlights off (maybe this is normal, but points me towards a second, or wrong bulb?) I'm getting no headlight/full beam symbols on the dash either. I've checked fuses for high beam (8,9) and they are ok. Just to add we recently had someone remove the immobiliser and recode the ecu as had an intermittent problem - I'm wondering if this is anything to do with the problem. Any help appreciated!
