Hi I'm new to the forum but have been reading it for a while.
Lately I have been suffering some powerloss mainly when on the motorway in 6th at about 3.5k the power just cuts and the accelerator has no response, if this happens a couple of time it goes into a limp mode and does it in all gears.
I done a bit of researching on this forum and decided to change my fuel filter, spark plugs and diverter valve. I done this today and the diverter valve was split so I replaced it with a revision D one and the spark plugs were a bit manky too.

After this I took it for another drive and it felt like a different car so much more power and smoother. But on the motorway the same thing still happens it goes into some sort of limp mode.
I got it scanned on vagcom and it cam up with only one fault. 000135 fuel rail/ system pressure too low.
I can see from the search function a couple of people have had the same problem but in both the threads neither seem to have posted that they resolved it.
Anybody have any ideas?? I was thinking of looking at the cam follower as its a 55 plate on 100k
Cheers

Yes definitely look at the cam follower.
I would further suggest that before you tinker, do some live logging of your requested and actual fuel rail pressure with vcds.
-
is your car standard?
-
Yes car is completely standard.
-
What other sensors are there on the fuel system.
What's the price of the cam follower?
Cheers

If your getting that fault, chances are that your cam follower has failed :sad1:
That will probably mean a new camshaft too. . . :surprised:
-
I hope not as it still runs fine unless your in 6th when it does it, I think it's sensor related because it's intermit ant, there's a low pressure sensor on the fuel pump isn't there, I also heard mention of a fuel pressure switch.
-
Well the car has slowly gotten worse and going into limp mode more, then on weds night the engine management light came on and stayed on!
So I went and got a new cam follower today and changed it and I think i have caught it just in time :surprised:

I also changed the seal on the fuel pump just to be safe too, what a rip off that is! £10 for a bloody O ring,
I can't feel any wear to the cam lobe Either luckily :happy2:
On the test drive after the engine light went straight out and the car is driving faultless now :laugh: soo much quicker now than when we 1st got it :jumpmove:
Cheers

Good to see you got it sorted. :happy2: nice systematic approach to eliminating potential causes.
-
Wow just caught the cam follower in time. :smiley:
-
Yeah glad it's sorted and I sorted via info from this forum :happy2:
Yep think looking at it it's the original it's done 101k :confused:
-
Is that the AXX engine code?
-
That cam follower :surprised:
-
I don't know what the engine code is to be honest it's an 55 plate if that helps with two metal fuel lines on the fuel pump.
-
A 55 plate should be an AXX engine...
