A good new battery does make the car feel newer. They come to life a bit quicker and are slightly less grumbling.
That's a very good way to put it!
It also started this morning, so wasn't just a random draw on the battery which is a niggle that was playing in the back of my mind.



Also managed to get to a small local car show at the weekend, with an eclectic mix of vehicles.
Selection of Porsches, Ferrari's, classic Fiats, BL, Japanese Imports, American, my st heap and some motorbikes. Was lovely to chat to a father and son who also had a 2.8 quattro avant in paradise green.

Incurred a lumpy idle over the past couple of weeks, with the plugs approaching 20k and the coil and leads approaching 140k i thought it could be wise to start replacing the aging parts.

Ordered some Desno K20TT plugs, as the marketing spiel grabbed my attention. Seems it also did when i last did plugs as i thought i'd not used these before. laugh At £17 for six, it's a relative bargain.
Not that i entirely know what i'm looking at but i don't think they're too horrendous.


The idle has been improved but still some shaking when onto low.
So today ordered a new NGK coil. At £90 quid.

Once that's arrived, i think i will get some custom HT leads made up. In Red, or yellow. Haven't decided yet. As i'm sure it's probably all over due changing.

Simply Audi has been re booked too!

It's Saturday morning, the sun is shining, i've 150 miles to travel.

My lovely automobile decides to absolutely scare the st out of me, with this sizable puddle of oil.
Level checks, engine oil is full, as is hydraulic oil for steering. Hmmm...Brakes, full.

Squeeze my head under the car. Can certainly say, it is the most relief i have felt for a failed hydraulic engine mount.


Well, we shall just add that to the list of mounts and actually do them all. That now means; snub nose, both oil filled engine mounts and the pair of grearbox. Gonna be a long day doing all those.
I don't think it's all leaked out as there isn't any greater NVH in the cabin. But will definitely get onto it after i've sorted ignition stuff.

Glad it's only a mount! And it's not much oil.
I'd be happier if my clio only left puddles of oil that small!

The photo makes it look better but yes, it's not excessive.
Haha, where does that leak from? OR where doesn't it? laugh






With the lumpy idle, i've decided to start going through some old parts that need replacing. Plugs done first and then the ignition pack. Purchased a NGK unit for approx £90. *Over night parts from Germany* which were very well packaged.


Surprisingly heavy.



As we can see, the original unit is pretty nasty. I have kept it as a back up, as did seem to be working just maybe not as efficiently as the new one.

Thankfully it's in a great location so was very easy to get to and replace.

I did notice however, that one of the bolts for the power steering pulley had backed out some.


Got that nipped up. Will have to keep an eye on it and maybe threadlock in place.


And back together.
Once again idle has improved but it's not perfect.

Seems to get worse when the car is very hot. So think definitely worth changing the ignition leads. Might try and find some yellow ones. Continue the arduous task of firing the parts cannon at it. Least the engine bay is slowly looking more fresh. rolleyes

I'm just trying to think of other things that have caused a dodgy tick over. Idle control valve? Dirty throttle butterfly valve?
Always happy to come up with more things to add to other people's part cannon.

At that age and mileage it'll be worth replacing the CPS and cleaning the MAF. You can check g/s in VCDS to see if the max airflow corresponds to the expected power output.

Yeah i think all are good potentials. It hunts the slightest amount on warm tick over but negligible. I still am leaning to it dropping a cylinder slightly. Perhaps will clean TB next. But that is buried. Eugh.

Would VCDS also pick up CPS issues? Didn't think of that tbh.

How hard is it to access injectors?

I don't think too hideous, Right on the top of the inlet mani. Can see the fuel rail surrounding the runners.

I can't believe the transformation you have made to this car after looking at page 1 and then seeing the photo further up this page, it's incredible, I love it.

Thank you, means a lot.
Certainly has come on along way. As always, still plenty to do!
