Engine Warning Light - problem found and help needed

[johnhol78]

Just run your fingernail on the cam lobe surface after you remove the follower.
If the follower is in good condition it should be smooth. If the follower is very worn down but not punched through then it's worth checking the cam for smoothness as a heavy scratched lobe can cause increased wear on the cam follower.

Ok great. will do that this weekend.

Well found the problem.....

Took the fuel pump off and first thing i noticed was fuel to the right and under the pump slightly.

The cam follower is fine, worn slightly but fine (will replace)

The worst thing was the o ring on the pump...perished and half missing. So must be fuel leak from the join to the engine.

So now need an O ring today - not likely from TPS or dealer due to time.

Any angels out there with an O ring for the fuel pump??? Cam follower would also be amazing - otherwise it's left till Monday afternoon.

I have an O ring lying about somewhere but may be pointless if you're not close to Manchester.

The vw dealer may be open on Sunday but the parts department is usually shut

Might give them a call tomorrow and beg someone to grab a part for me.

Hi John, loosing the hpfp seal can be.... If not fully addressed a serious problem! There will not only be the issue with power and the EML light you are experiencing but also the potential consequential damage caused by the fuel seal failing and leaking fuel into the cylinder head! This maybe a given and I apologise if you are already aware of this but you must make sure you change you're oil and filter after an issue such as this as the oil will be thinned out by the fuel which will be less effective as a lubricant and depending on the degree of fuel contamination become way more combustible than it would otherwise be, risking unnecessary wear and at worst severe engine damage!

Right logs attached.....on the way home couldn't accelerate over 3k rpm, found air filter hose not connected to grill and pointing down....reconnected. Went out after dinner and pulling like a train again....Doesn't look fuel related....

This is a nightmare...all fine last night though today on the way home same thing happens. But logged it this time...Fuel Pressure has differences of over 30 sometimes and boosting is none existent.

Log is here: https://docs.google.com/open?id=0B9iyWw-ZADAfQkN3ekxnWno5b3c

Any experts give me an opinion before it goes into a garage.....new pump, sensor??

Any chance you could log block 103 for the low pressure pump?

If that's ok, I'm wondering if you have an A version cam that has worn down in spite of the follower being ok.

Cam felt smooth when i replaced the follower.....Will try and log 103, will be tomorrow now though

Thing that gets me is that it's fine then like the last log - intermittent. If the cam was worn would it not be all the time?
