Please note, there are three or more of these exhaust gas temp sensors fitted to each car, one before the turbo, one after the turbo (but before the DPF filter) and one after the DPF filter. Also, most cars have lambda probes fitted too, so please ensure you know exactly which item you want to order.

The diagram below shows the layout on most cars, but this can differ and these are a minefield to get right, so it's essential that you have a diagnostic printout from the car and know which item(s) you need to replace before ordering from us.
