The difference between the two is?

just the brand name?

Bosch supplies VW with the lambda sensor. There is a slight superficial cosmetic difference between the two but the sensor is identical. I should know as I'm using the Bosch one.   :smiley:

Cheers Ayoub  :drinking:  will look into this first before thinking about changing!

Well today, I started of with a simple boost/vacuum leak test, the objective was to find bubbles from where I had sprayed the different parts with soapy water, no bubbles, none seemed to be sucked away either, I replaced the PCV gasket, nice new one in there now, replaced all the boost hoses in around the DV, serviced the DV, some fresh forge grease in, added a custom spacer in, only cost 10p, so thought I would try it,  re-fitted the throttle body hose, as I was not 100% happy with the fit, clips all tightened up, replaced the MAF sensor with a spare I had, scanned and out for a test drive, I have to say the car drives great  :driver:  love it... But problem still there!

The next thing I would like to try, is cleaning the throttle-body flap, what would be the best to use?

My idle seems to tick over between 720-760 rpm's, can this be adjusted in anyway?

Thanks

Nope.  It reads the speed.  The idle is in the mapping.

Get rid of the forge valve and try a rev G.  Could also be a small leak from the brake servo pipes.

Probably cheaper to just get a new hose if there is any doubts for just under £29. And you will need the small green plastic bung as well if you get a new hose part #  056129777
