Which MAF Sensor is correct?

[Mr Roboto]

Can any one tell me which one of these MAF Sensors is correct.

They both have the same part number stamped on them.

The top one is the standard Bosch Sensor and looks the same as my old sensor.

The bottom one is a after market one but it has the wire on the out side.

Are the the same just the Bosch one has the wire inside the plastic casing?

it looks like the top one has the connectors for the the resistor like the bottom one, you sure it hasnt fallen off?

 

[Mr Roboto]

Don't know?

My old Bosch one looks the same as my new Bosch one with no wire.

It's just my after market one does?

I would of thought the after market one was correct but having two Bosch sensors with out the wire is to strange

 

[Mr Roboto]

Got the answer direct from SEAT.

My ECU does not require the heated wire/resistor

Instead my ECU just needs uses the filament.

Tried both now and they are right!

The wire one confuses my car and throws up a error.

The filament sensor SEAT sent me works a treat.
