New Mk5 Owner - Cam Follower Nightmare

^^^^ Will, the Cam sensor is 06C 905 163B, I replaced mine after a chat with Kev, smoothed out running issues I was having  @willk86

@fab5freddy cheers pal, that's what I'm hoping for too

FWIW, I've spoken to 4 people about the cam sensor now (2 of them not on the forum) and they've all reported better running after swapping it out.

You do need to pull a battery lead before replacing it though, to re-register it, otherwise the ECU may carry on ignoring it.  They're funny cars these.  They do pre-flight check when you turn the ignition off (you can hear the throttle flapping about), so if you pull a sensor with the battery connected, it'll fault code it.

The timing could be a tooth out if it feels flat off boost.  Have you scanned measuring blocks 91 and 93?

93 should be in the 0 - 3KW region and 91 should show 28KW requested and 27.5 - 28KW actual.

I havent got VCDS to check unfortunately. But i have noticed at times it feels more sprightly than others - I think it may be down to my grabbing brakes at the rear though - My next job! Would there be any other symptoms? It idles well and fuel consumption is okay.

VCDS should be a default purchase for VAG owners!

Your mpg is pretty low as well, and with the intermittent performance you mention, I'd be checking the cam sensor.   It's probably caked in swarf from your cam follower nightmare.  I would replace it personally, it's only £30 from the dealer.    Mine ran a lot smoother, better idle and better mpg when I changed it on mine.  It's a common issue for metal dust to stick to them and skew the readings to the ECU.  You don't get a fault code from it unfortunately.  Good old fashioned detective work required for that one!

I would take the plunge and go for VCDS but it's well out of reach at the moment as it's pretty expensive and can't find it anywhere without spending a couple of hundred. In the meantime I'll have a look at the Sensor just to rule it out - it sounds easy to replace from what I've seen.

Understand that mate.   The way I see it is I can pay £100 for a Dentist checkup now, or put it off for a year and have to pay £1000 to have a new tooth put in 

Have you looked in the VAG-COM location thread to see if any members near you have it?

You don't need the full blown Ross-Tech version.  Some of the cheaper OBD2 setups apparently work well.
