Hi all,
couldn't find much relating to this so starting a new thread.
Been working my way through various problems on a 2006 Golf Plus, with the current one being;
"EMISSIONS GARAGE"
Car turns over but doesn't start.
Fuel pump was changed a few days ago and verified pumping into the filter cylinder.
What could be causing this fault on the display?
EGR valve?
Lambda?
Etc.?
Disconnect the exhaust it maybe a cat issue.

Thanks for that.Quote:

Ok,
cleaned the EGR valve which was well gunked-up. Not near-blocked gunked but dirty. Then tested it, by sucking on the nipple :biglaugh:... (lucky me!)
Then cleaned the V157 flap and tested to see if the motor was turning and engaging. All seems ok.
Still getting "EMISSIONS GARAGE" warning on the dash, with the car not starting.
Speaking of which, can someone confirm that this 'emissions' warning prevents the car from firing?
Edit... Seen other cars with the same warning which start fine so there must also be another problem, shame don't have access to diagnostics
Tomorrow is another day, so intend to get underneath to clean up some more, check the glowplugs, check the LAMBDA and see about disconnecting the exhaust.
It does not have a lambda sensor unless it has a DPF and it should be a BKD engine with cat and no DFP, it needs a fault code read.
I would bleed the injectors, get a safe procedure for that
Also if the fuses were messed up could the relays be also?
They are embedded in the head and are self bleeding.Quote:

All 4 plugs tested @ 0.6Ω, but no voltage, so went to check the relay.
VAG # 038 907 281 D
Bosch # 0 281 003 038
Pin number layout is
G1, G2, G3, G4 - in a row
.... 87, 31, ....
D1, ....30,., ST
Measuring resitance gives either 'open circuit' or readings climbing in the mega ohms before going 'open', which on a normal relay would indicate 'broken'.
Need to get inside to see if there is a transitor or two...
Can't get it open (yet) so does anyone have a schematic or pin-out?
Seem to be getting +12v to both pins 30 and 18 from the relay socket
Got the little fella open.
Far from being a regular relay...
Has a 24 pin microchip as well as 4 N-channel mosfets, a diode and various capacitors and resistors...
Seeing as the fuse is good and the plugs are good, this is getting replaced.
There are lots of bits you could spend weeks teating, replacing and spending money on. Can you not get a VCDS or at least OBD11 type reader off of eBay to give you more info on what to look at?
