I can certainly imagine that living by the coast would mean that exposed parts of the vehicle would be more likely to corrode then a car which was kept inland. I think that you will need to take some expert advice on this.
In terms of the clutch problem, it certainly seems to me that you are probably right. I would expect the clutch to last longer than 21,700 miles.
Under the consumer rights act you are entitled to have a vehicle which is of satisfactory quality and remains that way for a reasonable period of time. I don't think you need to worry about the warranty. Warranties often simply impose limitations which are intended to confused people as to the true nature of their rights under statute.
I would suggest that you find another reputable garage – authorised by Peugeot – to give you a quote for diagnosing and repairing the clutch problem. Best to get two quotes but don't stint. Make sure the quotes come from authorised Peugeot repairers.
Then send the quotes to your dealer and tell them that if they don't agree to repair the clutch under your statutory rights that you will have the repair carried out by one of the garages which provide you with an independent quotation and you will then come to them for reimbursement – in the courts if necessary.
By the way as part of the report from these two garages, you should get from them a statement confirming that they believe that the clutch should have lasted longer than the 21,700 miles.
If it is necessary to have the car transported to these dealers then it would be a good idea to inform your own garage first that this is what you are going to do and that you will be looking to them to pay all of the expenses that you are giving them seven days to agree to carry the work out themselves including transporting vehicle.
Does all that make sense?
Argh. I no sooner sort out a parking problem when back I come for an alleged driving offence, received today. I'm confused, though, because..
(a) The location they give for the offence - there is no camera at that point.
(b) They are a bit ambiguous with whether it's a speeding offence only or also a red light offence, as the NoI says "This vehicle's speed was recorded at (or seconds into red if traffic light offence): Speed 40mph"
Should I in the first instance just ask for a photo? (Whilst I am the main driver of the car, my partner occasionally drives it, so a photo would clear up this, but more importantly it would clear up the whereabouts of the mystery camera.) If so, I would rather mail a letter to them rather than go online to check, would this be okay?
Don't touch them owe me £500 since January 2019 make excuse after excuse. Seem they always have software problems sending money out. Keep saying they will call back or email nothing been chasing it now for 6 mths the phone staff always have the same banter we will chase it up and get back to you then nothing!
