Climatronic Controls 1.9Tdi Ghia X 1999

[Gadget]

New owner of 1999 Galaxy Ghia x 1.9 tdi. has a few faults which I have no problem in dealing with except for one, which is the climatronic control panel ambient air reading shows -- deg C. All other readings and operation of the panel are functioning as expected, assuming that this reading comes from a sensor I suspect the sensor to be faulty, Enquiries at Ford main spares and an online sensor supplier for a replacement result in the response that there is no sensor for ambient air in their database for my vehicle, so where does the climatronic get the reading from.? Obviously no reading without relevant sensor so where is the sensor located, looked under the grills but nothing found except that three pairs of wires appear to have been chopped off near the horn position (the front fog lamps appear to have been removed accounts for one pair of wires, the horn has been rewired to bypass a fault within that system which accounts for another pair, so maybe it's the third pair that should be connected to a sensor?) I understand that this is probably a VW component. So if anyone has a solution to tracing the missing sensor and getting a reading on my climatronic, I would be grateful.

Further to this I have been looking at the climatronic specs and found that if ambient air sensor fails, the controller falls back on the air intake sensor, could it be that ambient air sensor was not fitted to my vehicle from new and therefore relies on the air intake sensor alone. This would explain why fords report no ambient sensor part for my vehicle..??

On the MKII it's here

 

 

The MKII Ghia has a temperature readout in the cluster as part of the trip computer (orange half FIS dislay) which uses the same sensor.

[Gadget]

Unfortunately my Mk1 has no bracket in this area that would hold the sensor or evidence of a connecting cable from that part of the loom. Also from the MK1 handbook, regarding the FIS display states

" EXTERIOR TEMPERATURE (Not displayed if self-regulating air conditioning is fitted) ". There is no orange part on my display just a monochrome LCD window below the rev counter.

But thanks for the picture which shows very clearly where the sensor and cables are located on the Mk2. :-)

Okay found the cables had been chopped off, and a hole that houses the sensor in the lower mudguard adjacent to the near side fog light. Sourced a sensor from a scrapped Sharan and fitted it, job sorted. :-) Temperature now reading on the climatronic.

 

Next sensor to track and fit. in the same loom as the MAF is another pair of cables which have been chopped off, suspect it is the air intake temperature sensor, need to locate where it fits on the air intake assembly, Will dismantle the air filter and hoses when the rain stops to try and see if a hole exists to connect and fit one.
