Volvo v70 D5 brake fluid level low warning lights
I have a 2009 V70 D5 ex ambulance which is police spec. My low brake fluid level light came on intermittently at first then a few days later stayed on indicating a code of 066 when checked at my local garage (not Volvo). My front wheels also have brake pad wear wires that have been taped up. I also recently had new front tires fitted and noticed these wires. After the light came on i checked these and found that one of the connectors was rubbing on the wheel. I removed the connection, on the other side I noticed that the two sensor wires had been twisted together so I left them as they were as they have been like this for a long time. I will remove the connector to see if this puts the light out. The first time the light came on I was driving in Derbyshire on some hilly steep roads so initially I thought the light was genuine, when checked the fluid tank was full. The steep roads may have caused the sensor float to move more which has alerted the warning lights. Luckily my MOT isn't till July so hopefully will find the problem before then

The manual does not mention a 'low brake fluid level' light. However there is one for 'fault in brake system' which is described as:
Fault in brake system If this symbol illuminates, the brake fluid level may be too low. Stop the car in a safe place and check the level in the brake fluid reservoir, see page 188. If the brake and ABS symbols illuminate at the same time, there may be a fault in the brake force distribution system. 1. Stop the car in a safe place and turn off the engine. 2. Restart the engine. • If both symbols extinguish, continue driving. • If the symbols remain illuminated, check the level in the brake fluid reservoir. See page 188. If the brake fluid level is normal but the symbols are still illuminated, the car can be driven, with great care, to an authorised Volvo workshop to have the brake system checked. |

police spec brake fluid warning light
I have a police spec V70 D5 2009, I had a problem with the brake fluid low. i have now cured the problem by disabling the brake pad wear sensor wire by cutting out the link and rewiring the brown wire to the purple wire on the plud to the brake reservoir. The brake pad loom forms a loop including the brake fluid reservoir so has to form a closed circuit. A break in the circuit will cause the warning lights. Unless you are going to renew the pads with wired pads then there is no need for this loop which if not terminated correctly will eventually cause the issues we've experienced

Thanks saved me a load of grief
Thanks Jerry, I had the dreaded light come on my ex police t6 and it failed the MOT as I wasn’t aware this was a failure, my local garage told me it was the reservoir or the sensor and they’d replace them both, I had a quick google and found your post, when I first changed the pads I opted for the cheaper non sensor pads and a garage soldered the wires together for me so no Warsi light would be displayed, as if never seen the light I would have never have known it would say low brake fluid, after reading this I asked a mechanic to quickly check these wires and sure enough one had come apart, a quick 5 min (cheap) fix and the car passed its mot, thanks for saving me a lot of cash and grief.

This linking of brake fault warnings to non existant brake fuild low levels is not unique to Volvo. I had a Peugeot which had a notorious fault in that when the flimsy handbrake on/off warning micro switch's contacts began to deteriorate and not make a clean contact and break, the low brake fluid warning appeared intermittantly. Apparently this drove other owners mad but once you knew the reason for the problem the solution was a fiddly £2.50 micro switch replacement. You'd think that with something as vital as braking, car manufacturers would fuilly develop the warning systems but apparently they all seem to have a blind spot in this area!

I tried scanning faults to no avail and started thinking it may be a brake control module issue. I google searched the precise details of the fault and landed on your thread. I took both front wheels off only to find that on one side the twin redundant wires that had been cut short and crimped together, one had scuffed over time and become open circuit. Plod didn’t do a very good job of decommissioning this V70 T6. Cleaned it all up and tucked them away properly connected and and encased in silicon. Job done. Can’t thank you enough for the heads up on this. One other thing I found on this car, it doesn’t have regular T6 disc brakes. When I bought new replacements, the motor factor said the bigger size is, as used on the 3.2 version. Thanks again :-) |
