It wouldn't fit, the TT is a Golf and the Fabia is a Polo. Tell the idiot to learn how to use a tape measure.

Don't bother buying expensive snake oils, stick with box fresh bog standard brake fluid, for the best performance freshness is the most important quality by far.

Yes, crisis averted. It's not a racing engine so plug choice is really not critical.

There is more than one plug which will work just fine with your engine, I thought the BKY was a 1.2 3 cylinder engine, not a 1.4 4 cylinder engine. Do you need 3 spark plugs or 4?

The plug you fitted was a bog standard single electrode type, these don't last very well but they're cheap, the triple electrode type is an upgrade and will last much longer.

NGK codes are easy to understand: B means 14x1.25 thread size K means 3/8" hex U means surface discharge R means resistor 6 is the heat range rating E means 3/4" reach T means triple ground electrodes 10 means 1.0 mm gap.

Don't forget that a diesel operates in the opposite sense to a petrol engine, more fuel means more heat in a diesel, less fuel is therefore injected during EGR which has the effect of reducing EGT whilst maintaining cylinder filling, this allows a diesel engine to operate in a lean cruise mode which reduces fuel consumption and therefore also reduces emissions.

It won't make any difference, the compression ratio is too high for the junk fuel you put in it, the ECU can't retard the ignition enough to stop the pinking.

Yes. Absolutely.

They're good plugs, it's bad fuel that ruins good plugs, so much electrode erosion that pinking is a certainty, you should only be using super unleaded with that engine.

No, it's still the resistor pack.

Try a stiff wire brush to get all that loose rust off the carriers.

What exactly is the point of the additional gauge?

I can't quite see how you'd extract the old bush and press in the new one without proper access to both sides of it. Knocking might be a broken spring or may actually be coming from the front from the droplinks.

At least one of your speakers has blown, it won't be the wiring.

The problem is the garage doing the scanning, it's almost certainly a coil pack but there should be a code for the misfire.

I wonder if your ASV flap is jammed causing the juddering and the fault code.

I would replace the front shocks as well since at 125k they will be effectively knackered.

35mm is equivalent to 1 3/8" so I doubt it's that size, 36mm bi-hex sounds about right.

spray contact adhesive.

Bed them in harder, sounds like they're glazing over, you should use new brakes hard in short, sharp stabs rather than riding them lightly.

Crazy talk, dyno figures aren't accurate anyway, a twenty percent increase for £300 is entirely reasonable.

Start again dude.

You're doing it with the drum off and the pistons have popped out of the cylinder.

It's entirely possible that the ECT sensor has drifted out of spec. causing the problem, replacing it is cheap and easy to do.
