1/ Electronic oil level sensors are none too reliable. I believe they are easy to renew. 2/ Yes it is normal for the fan to run for a few minutes, though I forget the reason why.

OBD11 is recommended by several folk on the forum. Your eight year old battery is well past its "sell by" date, and no, you can not revive the battery with any equipment. Internal sulphation of the electrodes and dendrite growth is irreversible.

11.7 volts the day after being used suggests the battery is dying, as do all the other symptoms you describe. You should get the battery professionally tested at a dealer or auto electrician, because a simple voltmeter test will not reveal internal faults in the battery which can interfere with the cars electronics. If a new battery is needed ensure you get it coded to the car.

Michael. You can certainly record music onto SD cards, but you need to record it in a format that the car is capable of playing. There are numerous formats such as mp3, wav, ogg for examples so you need to find what format your car needs. If your car does not have an SD card slot then you will need an adaptor to plug into whatever input socket is available. If the car has a USB socket consider using USB sticks instead of SD cards, though the same considerations of formatting must be applied. There are many classes of SD card which are categorised on data transfer speed and capacity. I think even a low speed card will be sufficient for music, though it is always worth getting something better than the bare minimum. https://www.kingston.com/unitedkingdom/en/blog/personal-storage/memory-card-speed-classes The subject is really too big to cover here so do some research or consult a car audio specialist.

Alex. There's no anger or snottiness on my part. I am simply telling you your legal position to avoid you having to bear the cost of the repair once the 30 days has expired. It is advice that you will find frequently re-iterated throughout this forum, however if you would rather not receive such advice I am happy to withdraw from the discussion. Good luck.

In a word: no. Nothing you can put in the fuel tank would have made more than a slight and very temporary difference to a blocked DPF, so you would have had to get it properly cleaned or replaced anyway.

For goodness sake take it back to the dealer as soon as you can, and forget about hurting his feelings or upsetting him. You have a statutory 30 days in which to reject the car if it is faulty. After that time the dealer will not want to know you as he will be laughing all the way to the bank. There's a very good reason secondhand car dealers have a poor reputation.

Not necessarily. The new belt may have jumped a tooth if the tension was wrong. Did you renew the tensioner at the same time as the belt? If the timing proves to be correct it is going to be difficult to diagnose the fault without a lot more information and testing. In your position I would get it professionally diagnosed to check against your own diagnostic tester.

That's what the manufacturers claim, though I don't know what the Stop/Start function has to do with it unless there is a specific setting for AGM batteries.

Jon. Have the five responses you have received and read been of any help?

I fully agree with Syed that no intervention is needed under normal driving usage.

That does seem to point to the ECM, though I am surprised it does not show on diagnostics. I suggest we wait for somebody more experienced to respond.

Good news Andy, and thanks for letting us know.

Emily. I fully agree with everything Magnet has mentioned. The voltage reading and the lack of starting problems are not sufficient evidence nowadays to prove a battery is healthy, therefore it remains suspect in my view until professionally tested. (I don't count Kwikfit as professionals in this respect.) I really don't believe I can add anything new to this topic until a proper battery test has been done.

Sorry Shaz, but as usual with audio recordings it is impossible to hear anything unusual. If the noise started after new tyres were fitted it may simply be they are generally noisier than the previous tyres, however it would not hurt to have them balanced again. It is not unknown for new balance weights to fly off.

How old is the 12 volt battery?

Listening to audio recordings has always been a problem for us. We each become attuned to the noises our own car makes, so when an unusual noise occurs the human brain can mentally filter out the normal noises and hear the abnormal noise. Unfortunately when a stranger hears an audio recording he hears every noise and can not distinguish the abnormal one.

Emily. I see you have looked the forum today. Any news?

That moisture is significant, and may indicate corroded contacts. There should be no moisture at all if the lamp is properly sealed. You could try spraying with contact cleaner, but I am not optimistic it will cure the problem.

Before spending any money it would be worth confirming a blockage by independantly flushing the heater matrix and the main radiator with water.

To be clear, the warning message refers to oil temperature, while the guage shows coolant temperature. It seems to me that the oil is cool because the engine is cool, so the real problem lies in your engine cooling system. Put that right and the oil temperature will sort itself out. The most likely problem is a faulty thermostat, though there are other possible causes.

I have merged this topic with the original from Siyab to maintain continuity and provide all the relevent information.

Ah, it seems I misunderstood. Sorry. If it is correct James that you are leaving the car at home while you are abroad why not just leave the old battery in the car until you return, and then renew it? If you are going to renew it anyway it does not matter if it discharges while you are away. Or have I still not understood the situation? Some more detail would help.
