Could just be that the parts are abit try as the oils not been flowing around keeping them lubed up mate

Definatly something to keep an eye on tho

 

[cupra collins]

the charcoal filter taps alot on a cold start this is perfectly normal so im told

 

[chrisbond69]

nah its got worse more apparent than before,

I doubt its that the parts are dry to be honest, Mine was sat for 2 months while i had the brakes sorted and if anything it feels better for it.

If your still in Benson, i can meet you and scan it with vagcom just for pieace of mind, even though i dont think knocking would throw a fault code? Im free all this week if you need it mate.

 

[chrisbond69]

im actually back home on leave in cirencester mate, wont be back at benson till 5-6th jan but yes please if possible

 

[__B3NNY__]

If you havent sorted it by then bud give me a shout and ill pop up.

Theres actully a very good road for logging near there aswell

 

[chrisbond69]

oh is there where would that be not the a34 is it

 

[__B3NNY__]

No, not there mate abit busy for that. I would have thought the road that runs near M+P`s would be good aslong as its not busy and late`ish, Ive just started using the small bit of bypass down near sainsburys at the oxford end if you know it. Not busy at all and never any cops around.

 

[chrisbond69]

ok well ill let you know in the meantime if anyone else has any ideas please post them

make sure the oil is topped up, my old car used to do the same thing if the oil was on the lower end of the dipstick.

Other than that take it for a good run, make sure everything gets nice and hot, as the hydraulic cam followers may have emptied over the time it's been stood (the check valves in the followers sometimes do leak).

 

[chrisbond69]

yeah i check before use most days but ill let it sit on more of a flat, still any more suggestions would be brill thanks

cold oil.... thick for pickup pipe on pump?
what grade oil in there.

 

[chrisbond69]

its only had service 2k ago, whatever the garage used, im not sure if not do you think i should replace it with some good quality stuff bill, if so where do you suggest getting some from and what brand,??

 

[chrisbond69]

anyone?

Had similar problem with mine recently. Dunno whether its the same but had a very noise engine on start up and knocking. Would settle down after a minute or two. If you drove on it though when it was still noisey, I'd get an oil warning light. Ended up that I had aparently drove through a big puddle at some stage and all my filters and stuff were soaking wet. Water had aparently somehow got into my oil too and that was causing the extra noise.... also why i was getting the warning light as the water was causing the oil pressure to take longer to build up.

Oil changed and everything dried out. Fixed the problem 100%.

Brill got some new oil today so hopefully that will be sorted
