After nearly selling my car a couple of months ago, I decided to keep so just had another professional detail and re-application of G-Techniq ceramic coating.

Had the first one done 2 years ago so this is a top up.

I guess this and the recent after mkt 18” gunmetal Prets means I’ve repented my sin of new car lust and back in the fold for a while, or perhaps forever.

The British Gas engineer called to do the annual service today and said “I’ve been here before”. I said “have you???”. He replied “yes, I remember the car”.

A while ago I was wondering why the start/stop stopped activating in my car, I thought the car actually had enough of the system itself!

Cut to the other week I went out to the car and it wouldn't start, instantly realised it was the battery as the dash clock was showing 00:00. Jumped it and down to Halfords to get a battery health check and it confirmed it was a dead battery.

Lifted a Yuasa EFB battery, and fired it in (Halfords want £50 to fit a battery!?!) 10 minutes later all done, got away without having to code it in.

Looks Great @Toeman! There's something with red paint and silver wheels that always looks fresh!

Disable Start/Stop it causes premature wear to the engine. A few YouTube videos showing 10K miles on S/S VS non S/S and the wear on the journals and bearings was significantly more on the engine with S/S turned on.Basically Engine Stops and the oil drains then a second of running with no oil when the engine starts again.

Did they code the battery? I would also code the battery if not to let the system know it doesn't need to charge the new battery as aggressive as the old one.

I loathe, hate and detest Stop / Start for the reasons above. Just another emissions dodge by manufactures. If I’m stuck in traffic I don’t need some detestable software vs. common sense in determining when to turn the engine off.
Always disable it as soon as I start the engine, second nature now.

Swapped the PCV valve. Straight forward enough. Purely preventive.
Also touched in a stone chip that was starting to bubble.

Had a gearbox failure on 83k, Clutch pack 1 electrical fault when hot, eventually ended up with only 2nd gear  :angry:
Did the ringing around with prices estrimated from £1500 upwards just for the mechatronics unit itself :sick:
So ended up removing it and getting it repaired at ECU Testing 48 hour turn-round and lifetime warranty for c.£500.
Refitted with new oil and filter, full service and fingers crossed all good for now.

Just ticked over 50k miles, so it was time for a manual gearbox oil change. I had my local specialist fill it up with Millers CRX 75W NT+ instead of VW OEM. Transmissions is noticeably quieter, gears slot in much more smoothly and the 1 to 2 shift is little less notchy now. Really happy with the new oil! £50 for 3 litres from Opie Oils and another £100 for labour.

Thanks to GolfDave for the recommendation.
