new pads, new rotors .. new brake sensor??

[drken]

Hi Guys,

Recently purchased a black mk5 R32 second hand. Due to personal reasons, the rwc couldn't be sorted by the seller in time, so we're handling the rwc... Unfortunately, the car didn't pass the rwc as the pads and rotors were too worn! Fortunately, the seller agreed to pay however much it costs to make the car road worthy. We were given a quote (which will be covered by the seller) to replace both the rotors and pads.
After waiting 4 hours, the mechanic tells me that the brake sensor (im not sure what this is... maybe he means the brake pad sensors?) needs to be replaced too as its faulty. Now this is kind of weird as he tells me that after replacing the pads and rotors, he did the road worthy certificate without any problems with the sensor, but after that, the sensor starts to play up, and now he says its going to cost me $100 to replace the sensors...

I'm just wondering, have i void my warranty/extended warranty by getting the pads and rotors done outside of vw? Will my warranty cover the brake sensors in this circumstance? What will be my best choice in this situation?

I've had little experience with warranty and just wanted to get a good idea before I do anything.

Thanks!

The pad sensors should've been quoted up, and replaced with the pads. No excuses.

Unfortunately for you, a sensor has probably broken when being installed in the new pads (the wires get brittle after a while, due to the heat). Ask for the extra money to sort out the pad sensors.

As for VW warranty, as long as you've used genuine parts, and the work was carried out by a lisenced workshop, your cover remains the same.

So does licenced work shop mean vw licenced workshop or just a licenced mechanic ?

Means both.

The wording in the book is "suitably qualified personnel", so as long as the mechanic has his MVRIC licence your good to go. This doesn't mean the warranty covers the mechanics balls-ups.

I've not looked at a MKV brake pad but I was under the impression the sensor was integrated into the brake pad? As UmaiiNai said, it should have been quoted. ANy mechanic that done a few brakes would know that these things stuff up more often than not. You quote them & if they are OK, you reduce the final bill.

We have a strict policy of replacing them regardless. It's not worth the headaches when they fail on the post-work road test.

Ah i see, do you guys know what this sensor does? Should I be receiving some kind of warning on my dashboard if it is faulty? Looking at the manual, the brake sensor light isn't on (the one thats at the top of the half MFD)

It is a wire loop in the brake pad friction material, that is placed in the last couple of mm from the metal back plate of the pad. Many brands don't have it and are just fine without it. Brake pads are visually checked when you car is serviced, so missing brake pads sensor is not a big deal. The sensor feature can also be disabled using VCDS (vagcom) or just cutting the wire from the pads and rejoining it, insulate it and tape it as close to the connector.
