Hi All, I'm pretty new to the site, but found its a great place to look if you have any problems, i'm driving a 54 octy 1.9 diesel estate on 164K, lately it has lost its oomph, with a noise that sounds like some coins scraping in a bowl, limp mode, emission light appearing etc, following links, I discovered Loftys Mr Muscle treatment guide , with nowt to lose but time, I gave it a go, to say it went easy wouldnt be quite right, one of the allen screws was a bitch to get out, but out it did come.

I didnt have quite the right tubing ( a bit too big) but it did go down into the Turbo, and as the white foam did come out the inlet it must have worked,

working the actuator does hurt the thumb a bit but it did free up, then went for a warm up run,

as I accelerated above 15mph I got an almighty screeching noise, a bit like a squealing fan belt on a alernator with worn bearings.

motor ran fine tho ? the noise seems related to the accelerator foot pressure, figuring that it was some dislodged coke deposit I did the 2nd gear redline and indeed blew a goodly amount of black out the exhaust.

back to the house slightly worried as screeching remained, then on to here and got really worried when i read posts on turbo failings and the big exspense involved. and NOT to drive it if it is a turbo failing

decided only course was to try the treatment again, and maybe dissolve more coke deposit away,

when it had cooled, first went to take the 2 nuts of the connecting pipe, and found I hadnt tightend them up fully, I had left a 2 mm gap, the horrible noise was coming from the metal gasket vibrating, hence it was related to accelerator pressure.

Allthough I only knew this as I took it straight out for a test drive, Silence , and much improved power.

so all ended up fine, but a question if anyone can answer,

How often can this treatment be done, every 6 months ?, a year?, or wait untill limp mode appears again.

I'm an urban driver rarely doing more than a 10 mile drive, and hardly any motorway,

Am I better doing a run on the motorway every now and then to "Excerise" the engine ?

so thanks to all the people who post, in the end I thinks i spent longer on the forum reading than i did doing the job, I must have missed the bit on check everything isput back right n tight.

Italian tune-up, once the engine is warm, is always worth doing for a nice clear-out Think of it a little like having a good cough when your lungs are a bit phlegmy

Do it as and when needed would be my suggestion - wait till the limps start occurring....
