Cam Follower Change (with banjo bolt)

[Rob.]

I know there are plenty of guides online on how to change the cam follower, but I didn't come across many outlining the differences when you have to tackle a banjo bolt fitting (just a lot of moaning about how awkward it is!)

I went through the usual steps of removing the engine cover, and noticed my HPFP had 2 metal lines underneath.

I didn't have a mirror to hand, so stuck my phone in, looking upward (photo taken after I'd removed the first fuel line)



That'll be the M8 triple square. Luckily I had a set in my kit (needed to remove the front seat mounting bolts)

One of the online guides suggested removing the HPFP fuse and starting the engine, which would cause the pump to depressurise. I checked some wiring guides online, and found the #27 fuse (the blue 15a I'm pointing to...took a photo so I didn't return it to the wrong location!)




Removed the top sensor from the HPFP first, started the car for 10 seconds, then killed it. Remove the fuse, start the car for 10 seconds again (it starts to splutter) then kill it.

When I went to release the pressure from the schrader valve, only a weak spurt of petrol came out (I stupidly didn't have any rags, and kitchen towel isn't really the best thing for the job)

This is the only angle I could get to work on removing the banjo bolt. A ratchet spanner would have been really handy   But I had to crack on like this, taking it slowly as not to cross-thread anything, making a lot of small turns. The 'leccy tape helps with stopping the M8 from falling down onto the undertray.



Once that's loose, as well as the other fuel line, pressure release valve and the T30 torx fixings, you can remove the HPFP and get to the follower. A bit of fuel may spill out when you remove the pump, so have the rags to hand.

This is what mine looked like. Car is on 73k, so I've got to assume that's how old this follower is.



And that's pretty much it. Put in the new follower, carefully line up the fuel pump and tighten the torx bits in stages so it goes in square, replace the pressure release valve and the fuel lines (start with finger tight, so you don't cross thread anything), sensors and finally the #27 fuse.

Prime the pump a few times by half turning the ignition key. Then start her up: as good as new

Do you have these on the tsi engine? or is it just the GTI engine?

Is this a common problem on the Ed 30 lump? If so what sort or mileage should I be checking mine?

Some guides say you need to set the car TDC is this needed?

Just the tfsi

Check every 20,000 or so. According to VW they should be changed at 40k I believe. Not a big job I did mine last month in 30 mins and I had the more alkwood two metal pipes. You don't need to set it at tdc. Have a look on this forum there is loads of info over the last three months to read to make sure you know exactly what it entails and how easy and important it is rather than start another thread as all the good info is already there. It may even be pinned

If modified I'd check every service, if not modified maybe longer.

Some people do 80k without issue, some people eat away their cam in 10k

I don't think Vw even have them in the service schedule, they ignore them along with the fuel filter.

[Human Joist]

Not surprised. The interval must have come from this forum.  Fuel filter is on to do list too.

Anyway here is the link from the other month with other info on links off it. Worth a read

One guide I read referred to setting TDC, but loads of others didn't. I believe it's to do with reducing pressure on the HPFP pump spring due to the lobe being at it's lowest?

Everything's working fine, so I guess it's not vital.

I might have a look at the fuel filter sometime soon too then!

I looked at mine last month and as soon as I touched it one of the clips broke and they are attached to the pipe and mega money

Is there any way of telling its worn without checking it internally? Or how would I know if it's knackerd ?

The follower...... No you need to take it out to check it bud. Does not take long and if your taking it out to check it replace it for peace of mind

If it gets to the point of being knackered, you've got a very expensive repair bill on your hands!

There's heaps of info online and on this forum about cam followers and how/why to check it :)

Cars going in on Wed to vw Southend should I ask then to change it under warranty?
