ecu light came on had it put on computer and came up with exhaust sensor got reset was ok then came on again is this a big problem ? what will it do ? what should the cost be about to replace
lambda or oxygen sensors are used to reduce vehicle emissions by ensuring that engines burn their fuel efficiently and cleanly, by measuring the proportion of oxygen in the remaining exhaust gas, and by knowing the volume and temperature of the air entering the cylinders amongst other things, an ECU can determine the amount of fuel required to burn to ensure complete combustion.
not sure what engine you have most sensors are approx £80
kin hell bit of a price difference don't think it came up a code just said exhaust sensor i think might be wrong though ! im going to ring them tom , theres was not a vac cam though( one for all sorts of cars )
is the only these 2 on the exhaust system?
sorry for the 100 questions pall ( wish i had seen you post before i booked it in then would of nipped up )
thats not good, apparently these sensors are not to good, quite a few people with vdubs complaining of the same issue as you. We have a golf at work showing the same problem as yours, its an 09 golf tdi its showing fault code P2453 DPF differential pressure sensor, its going in on monday.
