19558 is no signal to the manifold flap. When you cleaned out the EGR did you disturb the wiring to the mani flap? Wiring ok to the motor? Because no connection is being made.

16785 - Did you disconnect the egr wiring or is the valve stuck?

The battery trick might do it, if not they will have to be cleared on vagcom.

imf update...

phoned eurocar parts today and they told me they hadn't got any in stock but can special order me 1 so going to order tomo.

had light taken out again today as came on after 3 days of driving vagcom on order from ebay so be able to do it myself.

even with light reset imf valve is wide open when engine is of and i can move it open and shut ..think by the sounds of it it is completely knackerd as have been told by a few people now the valve should be shut when engine of.so suspect that the valve does not work what so ever.

also glow plug fault came up so wondering how easy to do as may put new ones in at the same time.

hopefully once dun all will be good .........

And you are sure that all wiring and fuses to it are ok, because that would kill it off too...im not sure if it would kill it open or closed.... suppose whenever the power supply was disconnected.

Hi there. This is my 1st time time on this forum, not quite sure how to post a thread. But I hope this can msg can be circulated. I have an audi a3 1.6 SE petrol 55 plate. The fan comes on when i start the car and stays on. The engine management light shows up.The temperature gage doesnt move from zero. The fan only turns off after I turn off the ignition and turn it back on immediately BUT only when the car has been driven for a minimum of 45mins. With the fan turning off, the temperature gage also starts working again and the engine management light turns off. The fan is basically working the oppostitely by coming on when the engine is cool and turning off when the engine has warmed up. may i also note that the car does NOT overheat. Can someone please help as i have got the thermostat looked at,the water pump checked and the air pressure switch that sits above the condenser also checked out but the problem is still exists.

There is a temperature switch for the fans on the radiator mate, id change that first. Its prob telling the fans that its hot and thus running them.

Sounds like it could be that or a dodgy engine temp sensor.

If the fans are on, it shouldnt prevent the engine from warming up. The thermostat should be closed, thus the fan would be cooling a cold radiator as the radiator will be isolated from the engine as the thermostats closed it off.

I think they call it a dual thermo switch

Part number should be: 1J0 959 481 A

Yeh cheers mate. thanx 4 the swift response. will follow up on ur advice regarding dual thermo switch. I dont have any warranty on the car so im going to have to fork out me pocket but judging from ur suggetions i would assume it wont be 2 costly as its a matter of looking at sensors or switches (fans wont need changing). oh with regards to the above diagram is number 10 the dual thermo switch? thanx again 4 ur assistance

Yep it is mate no 10. on the diagram. I'd start with that, I wouldn't say it would be overly expensive.
