I'm not too flash with C-Rail, but that might suggest a not so healthy injector on 3, with 2 not a whole lot better. Hoon some injector clean through it and give it some jandal? I think Audi/VW forums might be able to shed some light.

Apologies, about 470mm

A tickle over 410 high I believe.

5-pot Audi - S4/S6 would work. They're made to sit on the left, but some handy work with a Tig and the outlets would point the right way.

N/A leaning for altitude compensation is just leaning until you feel some very slight rough-running then yes, back it off on the rich side. Turbocharged things will usually have you keeping an eye on the EGT gauge and the manual might specify 25° lean of peak, eg: lean it out, then keep going leaner once it's hit peak until you hit the number specified.

Yeah, likely a lot less room up the front of an Imp compared to a Skoda Estelle but they survived fine without louvers or slots.

Nah, he's throwing a radiator up the front.

What's the overall condition of the engine? I've seen a Hyundai Lantra? where the dipstick did a similar thing but required multiple dips before anything would show. Sump off revealed a thick layer of hardened sludge within, and a long cone shaped pillar of sludge surrounding the dipstick at a tight enough tolerance that with the dipstick in place, it was oil-tight. Each removal of the stick allowed a little more oil up into the pillar until you'd get a reading.

Depends where they source it from - The usual mob of thieves buy the same stuff as you said, and add the same additives under their own brand names, to achieve the same result. Gull source theirs from elsewhere, hence the higher lab test results - 91 = closer to 93, 95 = closer to 97.5 - coincidentally the figure that BP/Mobil 98 guarantee as their minimum RON and their 98 = closer to 99. NPD likely score their 100 from Gull 98 and top it up with toluene to hit the magic number.

Hopefully, I believe it's cracked (distilled) to a higher octane than the BP/Mobil offerings so has less additives to bump it up to the the 100 mark.

Yep, still ethanol. Throw some NPD 100 at it and enjoy.

Thumpers ring a bell.

Yellow gets my vote - it would look great next to @yoeddynz's blue one!

Good stuff! On the bright side, a gearbox is a relatively simple thing to deal with compared to some of the gremlins that Renaults of this era can have. VW diffs of the recent past have a similar issue where they are retained by a ring of rivets but thankfully there are off the shelf kits with super high strength bolts to replace said rivets.

Correct.

That's an ignition cut, with the fart being the unburnt juice igniting downstream.

And so begins the slow march to 911 ownership! They're not horrifically difficult cars to work on, and there is a decent logic behind the way things are designed and assembled in these and pre-996 911s, as opposed to other high performance vehicles of similar vintage. As you're no doubt discovering, there's a large amount of aftermarket suppliers too which helps.

Likely works off individual wheel speed differential via ABS sensors. Take it for a hoon and see if it clears the light. VW/Audi products light the dash up like a Christmas tree after disconnecting the battery and they'll all resolve within a few hundred meters when they get the feedback they're looking for.

Miami Blue! Otherwise known as beach public toilet block blue... Looks like an easy save and comes with a parts car, so I'd call that a win. Is that an old Octavia sitting to the right of it in the paddock pic?

Nah, it's the ABS sensors - All it's doing is measuring wheel rotations relative to each other while taking in to account steering inputs. There's a good chance the other cases you found were shitty sensor pickups/wiring or just plain shit tires creating a bit of slip.

Another culprit for this - If you've got lower/stiffer springs and the car is capable of cocking a rear wheel around a corner, that pings the TPMS as well. Wheel size won't matter at all, as long as all 4 are the same diameter.

I see a lot of Mk6 imports on those rims - Super light, but being so open they're begging for a big brake conversion behind them...

Fuckin hell that's some serious boots. What's the price point between the 4s and 5s?

Not interested in a Mk7 to add to the herd?
