No mate, seem to be working 7.5 days a week at the minute!

That's not good. Everyone needs a day off now and again.

I have them in stock

Thanks Alex. Are you going to Chessington on Sunday?

A few years ago, Alex (error404) was able to supply gold contacts to put into the MAF connectors. No idea if they are still available but I'm sure I've read somewhere in a Bentley service manual that there is a procedure during fault finding on the engine that; the factory specify replacing with gold plated terminals.

Put some in and avoid corrosion problems in the future!

(or find an aftermarket connect with gold pins already in and solder that into your loom maybe)

Ok, I read up here about the MAF connector. I cleaned it up with proper contact cleaner (I think I used WD40 before). Took her for a spin and........... ... wow she really goes. No boost cut, smooth as a turbine all the way to the top

Ah that old chestnut, you maybe read that it took me ages to finally cure mine. If it seems to be coming back again then pop the pins out of the connector shell and clean them properly or replace them.

Glad she’s going properly !

That is gonna be a worthwhile investment. Make sure to post some details on what its like to use.

This video is the best one I could find that shows how the tool is used and its the same set up as the S2 Avant. I wouldn't recommend using the air gun during the procedure as if something isn't lined up correctly, things could get broken fairly quickly.

Looking good

Thanks very much. All the hard work is starting to pay off

And I found this

Zoom in and you can just see the outline of the Scotts motor tune sticker that was on all the Nothelle cars.

Then gave her a good scrub


And oil change no 4 since the engine re-build. Gone semi synthetic for this one then will be fully synthetic Fuchs next one ( in about 1000 miles).

Is it a hard cut out ( tries to chuck you through the windscreen?) overboost or MAF cut?
Or a misfire?
Misfire at 4K might be IAT sensor..
Anyway, pull codes and see if you’ve got a boost pressure exceeded code

not going through the windscreen. Boost cut I think. I will check for codes later today.

Surely its run in buy now? The only thing that might need some sort of running in are the rings and bearing surfaces? And I would think they are fine after a few little drives. Never seen anyone in any sort of motorsport doing any running in... They whack it together, start them, warm up and then just send it. Dirtbikes, snowmobiles, cars whatever. I do understand your concern though, as this car keeps haunting you with niggles.
