So 24 month (oil, brake fluid, coolant) service went fine including optimisation however I had my check engine light investigated and turned out the exhaust valve had been “stuck” open somehow.
Not a huge issue as only the my 2017 cars and newer have this which just means the car is louder under 2500rpm, as you exceed that RPM the valve then opens fully anyway.
In practise the valve makes hardly any difference in quietening the car down so I never turned it on!
I have experienced another intermittent issue which is the nav unit occasionally turning off. Seems to be no rhyme or reason behind this but it powers back on fine. As predicted Nissan couldn’t replicate the problem.
After the track day the tyres and brake had taken a hammering and the OEM discs have started to develop hairline cracks, showing a 70% total wear on the brakes according to Nissan. Apparently very common and means they often get switched to higher performance discs.
Tyres are 3mm front and 4mm rear so not totally gone but slightly marbling is making the ride abit rough so will switch them out ASAP.
The rear wheel bearings are on their way out too which is suprising and can be heard at low speed which is annoying.
All this considered Nissan kindly dropped a modest bill, totalling £15k!
Broken down into the below:
- 4 new tyres £2k
- front discs + pads £2k
- new nav unit £7k (warranty covered)
- rear wheel bearings £1k (warranty covered)
- exhaust valve + new back box £3k (warranty covered)
So £11k warranty work and £4K consumables.
I have had quotes from auto torque and litchfields for the brakes + tyres for circa £2.5k which do not affect the warranty either.
First month of ownership is going well
