New member - Hi folks - with a problem of course......!!

2003 V70 D5 suddenly puts up dashboard message 'check brake lights'. I do so, neither side working, so assume its the bulbs (both at once....??) and replace. Still out. High level LED bar on tailgate working fine by the way.

Check fuses - boot fuse box no.3 and 14 intact (as identified from handbook) and have live feed. Under bonnet fuse 12 intact.

Earth from rear light assembly fine (indicators use same earth and no problem at all).

So.....?? As the LED bar is working the brake pedal switch must be working - unless it has separate contacts for the LED bar and the 21w circuits. Anyone know whether that is the case?

If so, where is the brake pedal switch so I can test / replace?

Any help/ideas/wiring diagrams much appreciated. A

Well I'm most impressed with the response............

In case it helps anyone else I tracked the poblem to a relay on the power board in the boot behind the LH trim. Blue (or with blue stripe) it 'splits' the brake pedal signal between the high level bar on the tailgate (which was operating fine) and the two cluster brake lights on the sides (which were not working). £5.00 for genuine Volvo part, and fitted in seconds - once you've worked out how to lift and pop off the trim.

Sorted - and the dealership said they do sell/fit quite a few......!!! A

Hi
Just got my V70 back today from a Volvo dealer with this problem.
Have been charged for two relays questioned why and was told that there were two? Part no. V08651661 and V30765030 £7.80 and £4.45 plus labour £34.40 all plus VAT. Wish that i'd read this first! Mike
