On 27th September 2016 I bought an Innovate mtxl wideband for £162.50 (sensor amd sensor control unit for my car).
This was installed by a professional mechanic on 10th October 2016.
On 11th November 2016, less than 1000 miles later, the sensor failed.
I contacted the company I bought it from requesting a refund
but they would only offer a replacement sensor which I eventually accepted.
The replacement was fitted on 21st April 2017 (the car was in stotage over winter),
the replacement sensor then failed on the 26th April 2017 with the exact same error code (E8) again less than 1000 miles later.
I have again contacted the company who sold me the product and they now state that there is no warranty on the product and the first replacement was out of the goodnes of their heart.
Having googled "innovate e8" there are many, many others with the same story.
I do not believe this product to be fit for purpose or of sufficient quality.
No way a sensor on a car should need replacing every 1000 miles.
The manufacturer of the sensor claims an average sensor life of 80,000 km
and other manufacturer's controllers that also use this sensor do seem to manage this.
I sent the company a letter explaining I do not feel this product is fit for purpose and they responded (in a rather unprofessional tone) they they would not be refunding me.
What else can I do to try and resolve this issue?
