Jaguar F Pace 2.0d low compression
Discussion
Car had been slow to crank so took it to local garage suspecting it might be battery or starter motor. No other issues - drives fine, has oil, serviced a month ago.
Garage called and said there is low compression in cylinder 1 - 100psi, compared to 280psi for the others. They don’t have the right tools to go any further diagnosing.
We have a warranty (Cinch car care) that actually has a comprehensive list of engine parts that it covers. The issue is they need the engine stripped to find the fault causing the low compression. Some garages won’t touch it as they said with the compression they’d be fitting a new engine and don’t want to strip an engine at huge cost to chase a problem. I understand why the warranty company want to see the cause (their money) but my worry is we do this, find the problem, only for them to not cover it anyway.
Just interested in advice or opinions.
I’m tempted to get a specialist to do a better diagnostic to see if they can narrow in on where the issue might be and see if the warranty company are happy enough with that (doubtful..?) or just cut my losses and list on eBay with the engine compression.
Thanks!

This is one of the reasons why we don't get involved with them. Your best option is to give Cinch a call and ask them if they have a list of approved repairers and then book it in with them.
Cinch are happy for it to go anywhere, even main dealer. But they won’t pay for it authorise a repair until the cause of the issue is found (ie. Crankshaft, piston crack etc). So it could be a huge job to find the issue. Also, worried they’ll see a cracked piston but want to know why it cracked and do more investigation before doing any repair. Not trying to be cynical about a warranty company but just trying to weigh up options. I was hoping they’d see the result of the compression test and go ‘that needs a new engine’ and sorting it - but understand why they aren’t going to do that.
The garage it is booked into also mentioned injectors and that it should be fairly simple to see if this is the issue. It looks from the warranty paperwork that as long as it is a covered part that has failed and then caused the other issue (cylinder compression) then it ‘should’ be covered.
Not sure though how simple a fix that would be or if it’s still a case of needing another engine if too much damage has been caused by injectors to the cylinder.
I’ve been online and seen a few f pace for sale as ‘needs new engine’ so looks like others have had to make the same choice with this engine.

Update to this:
Car went to engine specialist today for further diagnostic.
There is scoring inside cylinder 1 so suspect cylinder valve or seal. The fuel injector looked fine.
Now waiting for them to speak to the warranty company to work out what happens next. Either that is enough for them to agree to a repair / replacement engine (as cylinders are covered) or they will need to do more work to see what has actually failed. The mechanics won’t go further until the warranty company agree a way forwards, which is fair enough.
Not great news.

UPDATE:
Warranty company won’t cover the claim because the car was serviced late according to the warranty company service schedule (annually / 10000 miles). We were late to book the service (by 5 months and 4K miles) as hadn’t received the normal service reminder from them until that point (normal email reminding us a service was due). When we got that we booked it in as soon as possible (couple of weeks later).
We have said this to the warranty company but even though they sent the reminder late I think they’ll tell us it still isn’t their concern as we should have serviced the car in line with their contract. Absolutely kicking myself as these services are included in the maintenance pack!
Frustratingly the car had that service (no issues found) and was serviced again this year (no fault found) less than a month before this issue arose.
Not sure whether or not we have grounds to win an appeal with the company (they have admitted internal communication problems) or if we just have to suck up a very expensive mistake

It's not hard to know when your car needs serviced.
But warranty companies will always try and wriggle out, it's what they do
5 months/4k is quite a bit over, even if in reality it probably would not make a difference to the failure.
Yeh cheers for that - feeling pretty great about it obviously. But warranty companies will always try and wriggle out, it's what they do

Grown reliant in this day and age of the reminders being sent. Odd to me that they did send a reminder but one 4 months late. When that got sent we booked a service that day. Not an excuse just saying it how it is - no intention of doing it late.
