I'm happy that worked out well for you. I get the impression you do a heck of a lot more driving than I do. So far my choice has always worked out well for me too, as it has for Jmagee.

To halve the wear and tear rate on the lock mechanisms/motors. And if you feel the threat level is negligible due to location and journey destinations as mentioned. Both apply to me.

Fair enough. I wonder if some pipework in/out of the EGR might be (partially) blocked, causing sensors to perceive a flow fault with the EGR itself? If that's what those codes relate to. Has the car had the emissions 'fix'?

The momentum of the car keeps the engine rotating, because it's still connected by being in gear. Accurate mpg figures are easy to produce for each tankful when refilled to (say) the first click. Simply note down miles covered since previous refill, then zero the trip meter each time you fill; convert number of litres of refill into gallons (divide by 4.55) and divide previous trip meter reading by number of gallons just used to refill. That's how many miles your car did per gallon on average, during the previous tankful. Doesn't everyone have a spreadsheet of these records? Alternative is to use a website such as fuelly.com or spritmonitor.de where you just feed in your data and it does the sums for you; watch your unit selections though.

Read fault codes before deciding on the cause of the warning light.

Have you checked this?

Munching some food now, but I seem to remember that a member with a rather inappropriate/over-modest username works in the battery industry and has previously commented about the robustness of the cars' systems with regards to 'sorting themselves out' irrespective of coding. @BigEjit are you able to assist, please? Completely understand if you don't wish to comment if it might come back at you professionally somehow.

Will have another look later, just off out to gym. Looked at a quick glance to be good, plausible engineering sense to me, and Banner are a VW group OEM I think.

Some great info here about the self-learning which makes coding just a 'speeds up the process' thing: ⊳ Registering the battery - How to do it properly ❘ Banner know-how (bannerbatterien.com) An 'executive summary' type quote from that page: Conclusion: Purchasing and BEM coding an original replacement battery instead of a replacement battery from the independent aftermarket –– which does not have BEM coding –– only has the short-term advantage that the complete functionality of all systems is immediately available. Please note: The battery reaches this functionality without BEM code, usually also after some time and various „trigger events“ (impulses, signals e.g. starts, cold starts, cycles).

Was the old alt pulley maybe moved across to the new alt?

Leave it on the car, connect it up as per the manual and you have more chance of things settling down.

It won't have done the battery any harm.

^ So that the car's battery monitoring system knows that it is being charged.

Fingers crossed that it doesn't tell you anything too sad.

You can buy a compression tester for about £15.

I would get a compression test if there's nothing obviously wrong with the spark plug on cylinder 3.

What is making you think they keep failing, fault codes? Have you tried swapping them around to see if fault follows coilpack? Is it the 6-valve 54bhp or 12-valve 64? Which cylinder is giving the trouble?

Have you checked the spark plug(s)?

I'd have a few more goes with the charger, since you have it.

I just knew you'd be along at some point to be a miseryguts. If you don't want to play, don't.

Awoken to power outage, so it may have to be the big petrol one instead!

Sadly, you both live far away, so no danger of that. I think I'd like it if you were neighbours. 🙂
