LC5F's Graphite Blue GTI - Pilgrimage to Caffeine & Machine
pudding:
Mine's in for MOT now. Got given a god awful Up! as a loaner :grin: I know it's a cheap car, with only 30K on it, but it feels and sounds about 10x older than my GTI :grin:
Anyway, well done on the cable tie trick, that's what I do :happy2: I don't even like jacking the car up to do an oil change, let alone a belt!
Those intake valves aren't actually too bad, in terms of carbon build up. I've seen a lot worse!
Interesting on the remaps. You could look through the history and call the dealer(s), or HQ, to see if it had a dealer update at some point? It will be on their records if it has. I'm not aware of any dealer applied ECU updates (mine's never had any) but you never know.
LC5F:
Pleased to say the Golf the passed its MOT -
I was a little nervous of my new PipeWerx sport-cat downpipe, been reading a lot of alarming reports on here of these failing their first MOT...
But shouldn't have worried, it provided CO figures of:
Fast idle - 0.07% - Maximum of 0.20%
Natural idle - 0.04% - Maximum of 0.30%
Typical - last night after a sudden burst of speed the ABS light flashed up and went away...cleared it this morning and took it for a 20 minute drive before dropping the Golf off 15 minutes before MOT appointment.
Only one advisory - sticking off-side handbrake cable - hopefully that can wait till spring, will replace both at the same time - fingers crossed we don't get snow, my Mk5 is the best car I have ever had for hand brake turns.

Yes - seen much worse valves too, but feel they were cruddy enough - if they hadn't been destroyed - I would have wanted them cleaned.
Are you saying it possibly a dealer update rather than re-map? it has a lot of dealer stamps in it its service book.
Got some time off next week, may make a trip out to the dealer with something to bribe them to look the information up
-Halloween is great for cheap sweets!

Hooray! Those are some cracking numbers for a sports cat... do PipeWerx use MagnaFlow cats do you know? Every car I’ve ever had with a MagnaFlow cat on has passed its mot and I’m pretty sure this one on my MPD downpipe is.

Cheers -
I was going to say I didn't know... but remembered I did snap a picture of the CAT PN and googled... you are correct, it's a Manaflow 59959:

Thanks for the prompt - it's good information to know and have the confidence that it should provide years of good use.

Nice :happy2:
Yes Magnaflow and Borla cats pass MOTs no problem. Being American, they have to be California compliant......the strictest air quality regulations in the world.
Years ago, boring story bro, I built a Corrado VR6 turbo and the only aftermarket cat that got it through an MOT was a Magnaflow cat from a truck. A large square one, not the barrel design like the one linked, but that one looks great for building your own DP :happy2: Notice how cheap exhaust parts are in America compared to rip off UK!
Not ALL aftermarket cats fail the UK MOT, and not always on the first test. But many of them require excessive warming up prior to the test, and fail on the 2nd, 3rd or 4th test.
The Magnaflow one just breezed it. No need to rag the sh1t out the car round the block 3 times prior to hooking up the gas analyzer. Every single time I've used a sports cat (even a GESI one - often touted as the best), the tester always comments on them being borderline.
Anyway, cats schmats. Boring topic.
Yeah it may just be a dealer update. Just bought a MK6 TDI recently and that's been flashed. Unfortunately we need VAS-PC and/or ODIS to compare the ECU file to what's on VW's firmware servers to be 100% sure.
