I dont know if anyone has any idea about this????

I now have a YRV turbo 1.3 and had a boost guage fitted reading 6/7 psi( i thought a little low)

My car had to go back to the dealer for new pads & discs(only 4K on the clock) when i picked it up from the dealer it was reading 10/11 psi(thats better )

I phoned the dealer to see if they had done anything to the car but was told "no we only changed the pads & discs"

Now 1 week later and a few more miles the brakes feel soft again and my boost is back down to 6 psi

ANY IDEAS?

 

perhaps the dealer disconnected the battery whilst doing the brakes which reset the ecu.

Try disconnecting the battery over night and see if the boost returns.

Run it on Optimax or super unleaded and see if the boost remains.

Spongy brakes - take it back and have a moan.
