Ok here we go.
I bought the car on the 21st November about a week later after visiting Chris at beaniesport and going for my first proper drive, I felt something was wrong. I went back to Chris the next day to see if we could investigate. Carried out the usual LSD tests, but they didn't apply. I checked gearbox numbers and we removed the shaft to make sure the diff was in there. All checked out so far. Even called Renault to confirm cup pack fitted and the gearbox numbers they had. I called Ktec and spoke to Steven their workshop manager and asked him how I could test it was working. He told me it would be very difficult to tell if it's working or not and the best thing was to pull the shaft and check the diff was fitted.
I notified Ktec of the issue on the 2nd December and said that I was going to visit another specialist and compare it against another megane and will come back to them.
Ktec responded on the same day asking why I thought there was an issue. I explained that the car was not behaving as expected. I had checked tyre condition, tyre pressure, different driving styles, different road conditions etc and that I would go to the specialist and take it from there.
I then went to see Alex at Awmotorworks shortly after. He drove my car and said yup something is not right. We went out in a megane and it was different for sure. The invoice stated there is an issue with the diff, but in order to find out what the gearbox would need to be removed.
I went back to Ktec on the 7th December stating what Alex had said and that I wanted the car repaired.
Ktec responded same day saying they couldn't look at the car because they were busy and that I should bring it back for a refund and send over the report from Alex. I responded saying I liked the car and didn't want to return it. I asked about repairing it elsewhere to which they rejected. They stated from a legal business obligation they would like to buy back the car so they could repair it in their own time and I could purchase elsewhere.
(It is worth noting I hadn't sent to report from Alex to them yet as I wanted a second opinion to be sure, so Ktec were still requesting evidence)
I visited another specialist and they drove my car. Initially they said it seemed OK, but we went round a few more roundabouts and the inside wheel span a couple times. He turned to me and said mine has never done that, there is something wrong. We then went out in his megane and even with cold semi slicks it didn't spin like mine did.
I then did some thinking and on the 22nd December I sent a formal email with the report from Alex stating I'm rejecting the refund and wanted a repair. If they didn't repair then I would look to repair myself and recover costs. They were given 14 days to respond and I have heard nothing since.
The car is booked in for next week to begin the investigation.
