gateway fault or? radio related

[olethalb]

Ok so i have a small problem which has now been 100% confirmed

to cut a long story short my car has full mk5 gti loom / modules basically everything electrical is mk5 gti

after i carried out conversion i fitted rcd300 headunit: this unit did not come on with ignition

then picked up rcd 310 (just for silver buttons  ) : this unit did not come on with ignition and randomly went into safe mode every other week

i then fitted an ebay rubbish do everything badly unit : this unit did not store some funtions (memory) but did wake up with ignition on

now the rcd300 and 310 were fitted for a short amount of time and i put it down to gateway coding, then the ebay unit i put down to just being a pile of steaming turd

BUT i have now fitted an MFD2 that the gti originally came with so gateway coding should be ok, but still does not wake up with ignition and flicks through safe on start up, i also have random radio comms fault codes and infotainment? errors

is this a duff gateway or something else? i've bought a replacement gateway of the same part number - 1K0 907 530 F - i don't want to tear the dash down if it's possible something else

any help appreciated

The gateway will need correct coding, and I would have gotten a newer revision (L or Q, for example).

After the gateway is sorted if it still continues with problems I'd check the looms. Something shouldn't be right.

the gateway is coded as factory with mfd2 bud

the replacement was £12 so worth a punt

The gateway to be correctly coded for a MFD2 or even a RNS-510 just needs the Navigation module added as the Analog Radio should already be added in all gateways. Not much into it, really.

sorry i meant the stereo coding is factory (came with mfd2) and is now again fitted with mfd2 so should be fine?

I've still got my old gateway that ran fine with the mfd2. Worth a shot?

It won't be the radio. It ran flawlessly when in my gti

[Shoduchi]

I understood. The gateway should be correctly coded for the MFD2, yes. You just need to make sure it's correctly coded for the rest of your Touran's components and that you have no errors.

For your symptoms I find it hard just to be an issue with the gateway but I'm not electrician...

everything is mk5 bud, every sensor / module / loom etc etc

i've got one on the way from ebay rich, i know it's not the stereo as all 4 have acted oddly, i don't know if it all worked properly in the golf before i stripped it down

it's just a right git getting at the gateway particularly if it could be something else silly

You might have a damaged loom or a poor connection somewhere related to the radio. Even with the gateway not correctly coded the radio turns on/off with ignition.

Sounds like a live/switched problem. Might be worth getting the tester out.

i suspected this but ebay crud came on with ignition

you can hear the disc loading but doesn't 'wake up'

I'd check the canbus coding unless someone has messed with the loom.

[olethalb]

loom all looks good condition and un tampered with

the long coding has boxes ticked for analog and nav in the gateway, thats as much as i've looked at so far
