Golf GTI Edition 30 : PCV replacement

Started to get a frequent CEL for P0441 Evaporative Emission System Incorrect Purge Flow.
Cleared the code several times (using a generic obdII reader + phone + obd doctor free)
I was ignoring it (as its not harmful) until....

Drove the 20 mile commute into manchester, parked up and the car had a low idle and was 'hunting'
The boost gauge also showed the vaccum had dropped at idle (from 22in Hg to 16 inHg)!
The revs would also rise up to 2k by themselves then drop (with no throttle pedal)
Pulling dipstick = no change in idle, so it was time to dig out the PCV valve I had ordered from ebay a while back for this very eventuality!

2007 Mk5 Edition 30

As at 2018 the current is 

2.0T FSI PCV Valve  06F-129-101-R bought from ebay £43

Old Versions 06F-129-101-N, 06F-129-101-L, 06F-129-101-K (my old version), 06F-129-101-F, 06F-129-101-C

Revision K for revision R.
114,000 miles
Never been replaced so this was the version from the factory.

Easy change on the drive in the dark
  • Engine Cover off
  • disconnect 2 vaccum lines
  • undo 4 bolts and replace (i kept the old pcv gasket)
Note : I did not replace any other components i.e. the rear check valve

While replacing, I did try blowing/sucking the old and new valves.
Interestingly the old valve appeared to seal ok (in fact even better than the new one!) but when fitted it solved the problem.

vacuum level reverted back to 22 inHg at idle, now smoother.

In theory the MPG should also increase
I never noticed any drop in boost levels during this time

A great advert for having a boost gauge

Golf GTI Edition 30 as a great fast vw secondhand buy


2006-2007 Mk5 VW GTI Edition 30: £12k-£18k

Quick facts: 1984cc 4-cyl, 232bhp, 6.8sec 0-62mph, 152mph
> Is this a good idea? ‘Oh yeah. The Mk5 Golf GTI Edition 30 was the first Anniversary model to use an engine that wasn’t shared with the standard GTI – a detuned 232bhp version of the strengthened 266bhp lump used in the Golf R and Audi S3. Coupled with the standard Mk5 Golf GTI chassis this produced a genuinely rapid and agile hot hatch with all the refinement and quality expected of the VW brand.’ 
> How much? ‘A decade ago the Edition 30, limited to 1500 in the UK, weighed in at £22,795. Today a meticulously maintained low-mileage model will nudge £18,000. That’s depreciation with a ‘d’ tiny enough to make a Leon Cupra driver cry.’
>What’s going to break? ‘The TFSI engine has a good reputation for reliability but coil packs can fail and the cam follower that drives the high-pressure DFI fuel pump can wear and needs periodic replacement. Oil consumption is not unusual but shouldn’t be confused with the dipsomaniac chain-driven 2.0 TFSI Audi engine used in the A4/A5. All Mk5s are prone to front-wing rust, DSG automatic models can suffer mechatronic module and clutch pack failures, and always check the air-conditioning.’
> Crippling running costs? ‘Edition 30 owners may be immune from depreciation, but money will need to be spent on cambelt changes which are due every five years or 60,000 miles – budget £400 when the recommended water pump change is included. Servicing is barely any different from more mundane Golfs although tyre life is understandably shorter.’
